Li Daoyu: Direction is more important than hard work

Direction is more important than hard work. Attaching abrasive tools to provide services for national major equipment projects, accelerating innovation speed, undertaking social responsibility, technological upgrading of production equipment is an important direction for enterprise transformation.

In April of this year, Shanghai and Gao (Zhong) used to represent the Coating Abrasives Association to participate in the "International Forum on the Development of Modern Machinery Industry" sponsored by China Machinery Industry Federation and China Mechanical Engineering Society. In this international forum, the academic level of the speaker is relatively high. For example, the former chief engineer of the Shanghai Machine Tool Plant, Mr. Zhou Qinzhi, an academician of the National Academy of Engineering of China, Professor Zhang Wei of Tongji University, and the CEO of many famous enterprises. And the young and powerful Ph.D., they have both profound theories, rich practical experience, and modern cutting-edge knowledge, which is called the last summit forum. After listening to their speeches, they benefited a lot. In the first half of the year, we also visited several exhibitions in Shanghai, which also broadened our horizons. Here I will talk about some of the feelings I received at international forums and exhibitions, so the topic of my speech today is "My feelings and associations."

First of all, I gave me the biggest feeling in the international forum. All industries are paying close attention to the future direction of technology development. I remember that the president of Tsinghua University warned them at the graduation ceremony of master's and doctoral students that the first thing is that "direction is more important than hard work." This direction is not only important for the development of individuals, but also a very important and serious issue for every enterprise and every industry.

Professor Qu Xianming, former deputy director of the China Academy of Mechanical Science, said in his speech that Laomei is also considering this issue. In the past, labor costs in the United States were very high, and a large number of manufacturing industries were moved overseas, and a large part of them were Moved to China, so China has taken advantage of low labor costs in the past few years, and has gradually become a manufacturing power in the world driven by the old America and the world market. What kind of result did Laomei do after doing this? The result is that the deficit between imports and exports is very large, and the fiscal deficit is very heavy. Everyone knows that our country has bought a large number of US Treasury bonds, which is the accumulation of the hard-earned money of hundreds of millions of working people. Now, the old Americans feel that this is not going to happen. They want to reverse this situation. But they can't beat China by manpower. It's only by technology. So in January this year, in the Washington Post, there was an American whimsy professor, Professor Wadwa, who published a In an article, he said: "When we combine artificial intelligence, robotics and digital manufacturing technology, there will be a revolution in manufacturing, which allows American entrepreneurs to start construction locally and produce a variety of Products, so how does China compete with us? The United States is destined to regain leadership in the manufacturing industry, and it will soon be the turn of China to turn around." He quickly passed on to the ears of our central leadership. The Central Committee asked the Ministry of Industry and Information Technology to study this issue. Some people who may be present may feel that the old beauty is a little delusional, but the science and technology of the old America is very developed. Our "Shen Jiu" has recently gone to the sky. Everyone is excited and happy for the progress of China's space technology; but the old American spacecraft has crossed. The solar system entered the Milky Way, and they will soon land on Mars. From the development of the old American aerospace technology, it can be seen that his scientific and technological strength is very strong, and some of the ideas that seem technically difficult now, in the near future It is possible to achieve.

Today, Old America emphasizes the development of "artificial intelligence." What is "artificial intelligence"? This includes two links. One is to have a perception system, just like human vision, hearing and touch. The second is to have a decision-making ability, which can decide the specific actions of the actuator according to the actual situation of the production site. After all, "artificial intelligence" means that the production experience and data accumulated by human beings are stored in the computer, and it is called on demand. The best example at the moment is that people play chess with computers. The CNC machine tools we use today only work according to the procedures compiled before the personnel, and can only do the prescribed actions, and cannot change the action according to the situation. Nowadays, a robot is often added in front of the CNC machine. The robot replaces the person to complete the automatic loading and unloading of the workpiece and the tool, and even allows the robot to move the workpiece. The idea of ​​the American is to add an "artificial intelligence" command system to both the robot and the CNC machine. After you hand over to such a production line, the machine can automatically produce according to what you need. He just doesn't want to. Relying on artificial labor, we want to achieve a high degree of automated production. I visited Yuli this morning and saw the control method of your rubber workshop. Although it is not the level of artificial intelligence, you have reached the level of parameter control. You need to match the glue. You only need to input the rubber number. It will automatically carry out all aspects of the work, which is a big improvement.

The question raised by the old beauty whimsy master has reminded the domestic scientific community to attach great importance to it. Everyone has begun to consider how this will be done if the foreigner really wants to do this. This is a very forward-looking direction. In addition, I got a message on the forum. Everyone knows that Foxconn, Foxconn is a Taiwanese company, is run by Guo Taiming. There are 400,000 workers in a factory in Shenzhen. Now there are his factories everywhere in the country. His workers are in us. There are millions in the country, but he is now equipped with 1 million robots on the production line in 2015. In addition, I heard that due to the difficulty of recruitment and the increase of labor costs, some stainless steel products companies in Dongguan and Wenzhou also raised the demand for polishing automation. What is the need for such processing automation to come up with new requirements for our coated abrasives manufacturing industry in the future? How do our products adapt to this development?

Yesterday I also visited Fengpu, and Feng Pu’s general manager told us that one of their products has been applied in a fully automated production line of Foxconn. I am very happy about this. The problem of direction is in many places. The key issue is energy. The key is whether our energy structure should develop nuclear power. After the earthquake in Japan, the nuclear power plant went wrong. Later, Japan shut down all the nuclear power plants, but then it was slowly closed. It’s too much to eat, and now it’s gradually opening up. The world is also debating this issue. Bill Gates said that we have a lot of energy, wind, solar, and tidal energy, but all these energy sources are better than nuclear energy. It is believed that nuclear energy is the most promising. This is a question that determines whether our energy development direction is correct in the future. Now the relevant state is studying it carefully.

I am talking about these few examples mainly about the direction of the problem, why should we mention this direction? The State Council issued an "Industrial Enterprise Transformation Plan" in January this year. What is transformation? It is estimated that many leaders have already heard the familiarity, but some comrades may not know much about what is called transformation. In fact, "enterprise transformation" is to make our enterprise rely mainly on expanding production capacity and expanding resource consumption. The way to change is a more effective way to increase product value and protect the environment. In the past two days, I was very happy to see that companies like Yuli have noticed environmental protection issues and achieved many results in controlling emissions. Environmental protection is an important issue in the transition, and the most important in the transformation. The question is still what kind of product, the Machine Tool Association has put forward a requirement for the enterprises in the association, that is, we hope to provide equipment and services for the core manufacturing field.
Breakthrough progress has been made. What are the core equipment? That is our nuclear power, big aircraft projects, shipbuilding, automobiles and advanced aerospace, etc., all of which require many of our companies to serve it. This morning, I saw that Yuli has used their products in some advanced processing fields. Congratulations on this.

At this China Modern Machinery Industry Development Forum, I introduced some of the results of our coated abrasive tools in providing services for major equipment projects.

The first is the grinding of large steam turbine blades for nuclear power plants. The blades of such steam turbines are very complex three-dimensional curved surfaces. After initial molding by numerical control milling, the milling must be further eliminated by grinding. Improve the surface roughness, thereby not only avoiding stress concentration, but also improving the smoothness of the airflow, which is very important for improving the efficiency and reliability of the whole machine. However, it is impossible to use the grinding wheel to process. First, the temperature of the grinding wheel is higher, and the heating process of our belt grinding process is relatively small. It has the reputation of cold grinding and does not cause surface burn on the workpiece; It is the grinding wheel to achieve a certain grinding line speed, the diameter is generally made larger, can not meet the requirements of the small radius of curvature of the blade, and the diameter of the contact wheel for grinding the belt can be made small. Chongqing Sanma Haida Company developed the six-axis linkage CNC blade belt grinding machine in 2008 with the demand of Dongfang Steam Turbine Co., Ltd. to manufacture 600,000 kilowatt steam turbine. Its maximum machinable quality is 180 kilograms and its length can reach two meters. It is impossible for such a heavy workpiece to be polished by several people like the small steam turbine blades used in the past; and the material it processes is not ordinary carbon steel, it is a high-strength nickel-based heat-resistant alloy steel, which is very difficult to process. . It can now be machined using a CNC belt grinder, but the belts used are not our usual silicon carbide belts, alumina belts and zirconium corundum belts, but imported VSM ceramic abrasives and stacked abrasive belts. The coarse-grained life of the abrasive belts currently used can last for about 2 to 3 hours, and the fine-grained belts can be used for 6 to 8 hours. Just visiting the picture of Yuli said that your belt is also used in the grinding of steam turbine blades. Is it also your newly developed stacked abrasive belt? This six-axis linkage large steam turbine blade CNC belt grinding machine has also been applied in Shanghai Electric Siemens Steam Turbine Co., Ltd. (known as the domestic famous Shanghai Steam Turbine Plant), which now produces supercritical large steam turbines. It can be seen from this figure that the Dongqi Group has used nine TX-6 six-axis linkage CNC blade belt grinding machines. It is reported that the total time of one blade coarse grinding is 121 minutes, and the processing of one belt grinding machine The ability can be matched with five CNC milling machines. By April 2011, the output value created by Dongqi Company in grinding blades had reached 330 million yuan.

This picture is a belt grinding machine for steam turbine wheel top round processing. It was specially designed and manufactured by Hangzhou Machine Tool Plant for Harbin Steam Turbine Works. It was put into production in 2007. After the blades of the steam turbine are completed, the pieces are assembled into an impeller disc. After the impeller disc is assembled, the top circular surface will have some unevenness. Now it is processed by abrasive belt grinding. One piece only needs 4 Hours, and the original processing with vertical car takes 72 hours; it can also ensure that the diameter error of the top circle is less than 0.04mm, and the radial runout reaches 0.02mm. However, the abrasive belt used is not a domestic abrasive belt. It is a 3M ceramic abrasive belt in the United States. A 42# abrasive belt can process three impeller disks.

Let us look at the high-pressure, heavy-duty containers in the nuclear power plant. Most of these containers are made of stainless steel or chemically stable nickel-based materials. The inner diameter of the 900 MW pressurized water reactor is 4 meters and 10-12 high. The wall thickness of the rice is generally more than 40 mm, the wall thickness of the active zone is 220 mm, and the weight of the whole pressure shell is about 300-400 tons. The stack of all welding bevels, weld height and inner circular surface is required in the manufacturing process. The weld layer is ground and the grinding work is quite large. Because the weld material is Inke 690 nickel-based alloy, the surfacing material is 20Cr-10Ni precipitated stainless steel, the material has poor thermal conductivity, the grinding wheel is easy to form blockage, and the grinding process does not allow the use of coolant, which is easy to cause surface burn; Moreover, problems such as deformation and dimensional instability may occur due to large grinding force, so grinding wheel grinding is not suitable, and abrasive belt grinding is used abroad. Imported nuclear power high-pressure container automatic high-efficiency grinding equipment, flexible and reliable, high processing accuracy and efficiency, but each unit sold for more than 1 million euros, and now Sanma Haida has also been able to produce such equipment. However, when it comes to the grinding belt used for grinding, it is still mainly imported sand belt. Other zirconium alloy cladding tubes, such as containment and encapsulation of nuclear fuel pellets, need to be ground with abrasive belts to ensure uniform wall thickness. Nowadays, this equipment has also been localized, thus ending the long-term dependence of China's cladding tubes. The situation of imports.

The following is a description of the services that need to be applied to the development of China's aviation industry. One of the major and important industrial projects in our country is the large aircraft project. At the same time, we are accelerating the technological advancement of the advanced fighters for national defense. The third-generation fighter æ­¼10 has been officially installed in the army, and the æ­¼20 with invisible function is still in the process. Flight test phase. Everyone knows that the United States has announced that its strategic focus has shifted eastward, deploying multiple aircraft carriers on the coast close to China, and its partner countries Japan and South Korea to purchase a large number of the latest all-weather fighter F35 from the United States. Vietnam and India also want to buy a lot. The purpose of this advanced fighter is to target China. We will not accelerate the development of our own national defense, and it will be very dangerous in the future. In the process of developing the aircraft manufacturing industry, aviation engines are a very important issue. The aircraft we built in the past were mainly purchased from the United Kingdom, the former Soviet Union, and Ukraine. This channel alone cannot be guaranteed for a long time. It must be subject to people. We must master the advanced aero-engine manufacturing capabilities of our own intellectual property. Here also encountered a grinding problem of the engine blade. The blades in the aero engine are different from the blades of the steam turbine. The blades of the turbine engine are large, while the blades of the aero-engine are small, generally 150 mm long. Some of the precision-forged titanium alloy blades are less than 2 mm thick. The thickness is even thinner to 0.15mm, and there are many places where the radius of curvature of the curved surface is very small, and there should be no sparks on the grinding. Otherwise, the blade will be scrapped. According to the introduction, the blade material of the large aircraft project is 200,000 RMB and 1 kg. The control requirements for the grinding force are extremely fine, only about 30 grams, and the processing process must not be negligent.

In the history of the development of our coated abrasives, there was a story. As early as 1958, the Shenyang Aircraft Factory, based on the advice of Soviet experts, used sand to grind the engine blades of the MiG fighter. At that time, the Chinese people I don’t know what to do, I will find the three mills to help solve this problem. Among the people who have experienced this matter, there is the general manager of Huang Sundong of Golden Sun Company. They have never seen the abrasive belt, but they have obtained it. A little bit of information, a number of abrasive belts were completely made by hand. Once it was used, it was the first chapter in the history of abrasive belt grinding in China. The first processing object was the aircraft engine blades. From the 2012 Nanjing CNC Machine Tool Show, we are pleased to learn that Chongqing Sanmao Haida Company and Beijing Shengwei Hongji Company have successively developed six-axis CNC belt grinding machines specially designed for aircraft engine blade grinding, respectively. West Air Power and "Wuxi Blade" were put into production. Unfortunately, the abrasive belts used today are still imported.

The propeller of a large steamer is made of copper alloy. After the milling of the propeller, the roughness is improved by grinding, but the grinding wheel cannot be used. Because the copper is easy to block the grinding wheel, the surface is polished with a belt after milling. Similarly, the accuracy and roughness of the propeller profile have a great influence on the ship's driving efficiency. Our national Wuhan Heavy Machine Tool Plant has already built a 5m diameter gantry CNC milling machine for processing large ship propellers. When this machine was presented to the central leadership in 2005, President Hu immediately asked: "Can this be processed? The propeller of the submarine?" This question is for a reason. In the 1980s, there was a "Toshiba incident" that had been raging in the world. When the submarine of the former Soviet Union arrived, the United States would immediately know that because the submarine propeller of the former Soviet Union would have a vortex when it was rotated. The sound, the United States can use the sonar to detect it at once, they feel very safe, but after a while the United States suddenly found out that they did not know where the submarine of the former Soviet Union was, immediately let the intelligence bureau investigate and found that it was a Toshiba in Japan. The company exported two CNC belt grinding machines to the former Soviet Union, so that the processed submarine propellers had no sound during operation. So if we can master these technologies, then our nuclear submarines can also be muted. Comrade Hu Jintao, who is the chairman of the Central Military Commission, is of course very concerned about this technology. Since all countries in the world are in the scope of national defense secrecy, China has not reported on this. However, the blade of the marine adjustable pitch propeller has now achieved abrasive belt grinding. This picture is the belt grinding machine of the adjustable pitch propeller of Sanma Haida. It can also be speculated that the abrasive belt grinding technology of our submarine propeller may have been solved.

There are also many important industrial occasions that require sand to be ground. The above examples are sufficient to show that the belt seems to be just a small tool. It seems to be insufficient, but it has a unique role in providing equipment and services for China's core manufacturing field. . In the “Twelfth Five-Year Plan” of the machine tool industry, China Machine Tool & Tool Industry Association has listed superhard material coated abrasives, polyester cloth strong grinding abrasive belts and special coated abrasive belts as key development products. Our accumulated abrasive belts produced by Yuli, the diamond belts produced by Zhengzhou Reiter and the ceramic abrasives successfully developed by the Far East are all examples of the progress of our industry. However, I still deeply feel that the development of these new types of abrasives and new coated abrasives in our industry is too slow. Many experts, including Professor Huang Yun of Chongqing University and Dean Zou Wenjun of Henan University of Technology, have been calling for speeding up. The speed of advancement of coated abrasive technology in China. In 2004, Sisha reported in the magazine that its ceramic abrasives have passed the provincial appraisal, but until now I have not seen the coated abrasives of domestic ceramic abrasives. The Secretary-General Dai Hongjun said that it has been used to consolidate abrasive tools. Can we work harder and use our coated abrasives? Our foreign counterparts have not stopped moving forward for a moment. 3M's ceramic abrasives have evolved from the first-generation products with irregular shapes to the second-generation products of regular equilateral triangles. The grinding efficiency is higher than in the past. It is. I hope that the entrepreneurs here can bravely take up the social responsibility of developing advanced coated abrasives. The safety of the country and the progress of the country require your contribution!

Professor Huang Yun introduced in a paper in 1998 that the proportion of abrasive belts in developed countries accounted for 30%-40%. At that time, the belts accounted for only 4% of the coated abrasives in our country. Better, some people estimate that it may account for 15-20%. I think the abrasive belt has the highest technical content in the application of coated abrasives. We must make the abrasive belt better. Now I have to go back to the sand page. Although the technical content is not particularly high, it is also an indispensable product in the society. The sand sheet product accounts for 50% of the annual output of coated abrasives, and the output value accounts for 25%. What is the progress of the sand page? I also came to Tongcheng with such questions. I am very happy to see that many sand sheet factories in Tongcheng have already had specific ideas to make sand sheets better. Some sand sheet factories have already put their own products. In the electronics industry with very high technical requirements; some sand sheet factories have set a specific goal of catching up with imported sand sheets, and have established two performances that are not as good as others. What is more valuable is that they are trying to buy instruments to test these two. Item performance, use data to evaluate the size of this gap. Talking with data is a very good idea. This concept is very worth learning. We can no longer rely on experience, eye-catching, and hand-touching to evaluate the goodness and badness of technology. It has entered the 21st century. The Party Central Committee has been advocating the scientific concept of development. It is necessary to use scientific methods and methods. To guide our technological progress.

Finally, talk about the technical upgrading of production equipment, which is also one of the important directions in the transformation of enterprises. As far as the entire industry of coated abrasives is concerned, the primary purpose of equipment upgrades is to improve the stability of product quality. I have visited many companies and the slogan “Stability is overwhelming” can be seen everywhere, indicating that everyone has paid attention to this issue. To improve stability, it is necessary to rely on people's sense of responsibility and technical quality, but the level of production line equipment is still the foundation of the material basis. In 2011, during the Zhengzhou Sanmao Exhibition, I heard a report by a British expert from Shengquan. One of his ideas is “no control without measurement”. The measurement here refers to the online measurement of the production process. I think this sentence is very correct. The measurement of the whole production process is basically post-event measurement. It is said that the β-ray instruments for online measurement imported by many factories are almost completely destroyed by the whole army, and all are removed from the production line. Last time I asked the US island company how to control the thickness of the adhesive layer in the process of producing tape film. They say that they use a beta-ray meter. Why do the measuring instruments that are bought at a large price do not accept water and soil in our country? This question deserves our deep thought. This time, Haifeng Paper Factory in Tongcheng saw a domestic online measuring instrument for paper quantitative and moisture content produced by “Gundam Technology”, which also uses the principle of β-ray. “Gundang Technology” is a high-tech enterprise jointly established by the Institute of Computing Technology of the Chinese Academy of Sciences and Mianyang, Sichuan. It has developed many online measuring equipment for the paper industry. It can be seen that our industry is far behind the control of the paper industry. Another example is that there are several foreign-owned companies in China's wood-based panel industry. Foreigners don't need to travel from Germany or Austria to China to direct production. Instead, they use the internet network for remote control. What brands are imported today? The production link is adjusted in place through digital control; if a fault occurs, it is only necessary to look at the computer's control system abroad, and after identifying the fault point, notify the Chinese technical personnel to eliminate it, which is completely remote control. And in the last international forum, I also got such a message. In September 2011, with the approval of the State Council, the special plan for intelligent manufacturing equipment innovation project was officially launched. The first batch of support has a total of ten directions, among which there is a certain relationship with our industry. The intelligent weaving equipment, etc., can be seen that all industries in the country are accelerating the upgrading of equipment control technology. However, what I often hear in our industry is: "I am an import line!" to show off your equipment level. It is true that foreign experience in the application of abrasive tools and equipment manufacturing quality has many places worthy of in-depth study, but with the rapid development of technology, the imported equipment in the past will not be the most advanced. In the long-distance running competition, some athletes may follow the tactics, and the purpose is to finally surpass. If we have never thought of making the production line level better than foreign countries, we can only be in a backward position. The purpose of upgrading the equipment level is to change our manufacturing powers to manufacturing powers. As a person who is engaged in equipment, there are still many improvements that can be considered in the equipment of coated abrasives. This morning, Secretary-General Wang Mingyuan praised the entire company that produces equipment for the industry. Indeed, there are many improvements in the products of the whole industry. Can you work harder on the control level of the production line? Now to evaluate the advanced or not of the equipment, the first thing to look at is control. It is hereby called on whether the whole industry can unite, conduct an in-depth analysis of our existing production lines one by one, find out the direction to be improved, and then propose a solution to the division of labor. The results will be finally shared, so that our overall equipment technology level will pass. This transformation process has been upgraded to an updated grade.
