After two years of scientific and technological research, Lanzhou Branch of Chalco as a "low-temperature low-voltage aluminum electrolytic aluminum reduction technology in aluminum 180-400kA series application and demonstration" projects, recently colored by the Association to carry out specific implementation unit Acceptance by relevant experts of the organization.
　　
It is understood that "low-temperature and low-voltage aluminum electrolysis technology in the promotion and application of China Aluminum 180-400kA aluminum electrolytic series series and demonstration" technology project, the feasibility study report was prepared at the beginning of 2013, and reported to the Ministry of Science and Technology through the China Nonferrous Metals Industry Association. The National Science and Technology Support Program was approved by the Ministry of Science and Technology in February 2013 and was granted a grant of RMB 600,000. This project combined with the technology promotion projects that Lanzhou Branch has carried out in recent years. Under the condition of non-stop-groove improvement, 341 electrolysis troughs have been popularized and applied. The average voltage before implementation was reduced by 0.194V, and the average power consumption per ton of aluminum decreased by 398 kilowatts. At the time, the average coefficient of effect fell by 0.207 times/day, and all the indicators were significantly improved. The energy saving brought annual emission reduction equivalents of 95,700 tons of carbon dioxide. Under the condition of stop-groove improvement, 105 "double steel rods" technology and steady flow technology tanks have been promoted and applied. The average voltage before stop tanks was reduced by 0.26V, the average per-ton aluminum direct current electricity consumption was reduced by 495 kWh, and the average effect factor was reduced. At 0.195 times/day, electricity savings brought about 45,800 tons of carbon dioxide reduction per year.
　　
During the acceptance process, the expert group listened to the report of the task group, reviewed the acceptance data, watched the company's on-site operation of the video material, and after questioning and discussion, the expert group finally agreed that the acceptance information provided by the project team was complete, standardized, and The use of funds is basically reasonable, and self-raised funds are in place. The project has fulfilled the tasks stipulated in the mission book, and has met all the technical and economic indicators required by the mission book. The economic and social benefits achieved have been significant. They agreed to pass the acceptance check.
　　
It is reported that due to the project's application for grants to the State, on the one hand, through the purchase of a batch of electrolytic testing equipment, it supplements the testing capabilities of the Electrolysis Plant and the Electrolysis Plant. On the other hand, the Zhengzhou Institute was entrusted with the Electrolysis Plant and the Electrolysis Plant. "Physics field" test, timely mastered the company's "double steel bar" technology and steady flow technology electrolytic cell operation, at the same time, to promote the company's technical progress related to the technical backbone of the performance incentives, greatly enhancing the technological innovation enthusiasm . The smooth implementation and acceptance of the project not only obtained state capital support, but also contributed to the company's improvement of aluminum electrolysis production technology, and accumulated management experience for the company to carry out scientific and technological innovation projects to support national science and technology projects.
