Widening the trolley is a successful technique that many small sintering machines explored in the 1980s. The experiment was conducted on the sintered cup: A ring-shaped steel plate was placed on top of the sintered cup, and a part of the circumference was closed to conduct a sintering cup test. As a result, it was found that there was no significant influence on the sintering time and there was no raw material in the lower part of the material layer. Based on this result, the manufacturer widened the upper part of the trolley under the condition that the width of the draft was constant, and achieved good results. With less investment, it is possible to increase the sintering area and increase production.
The method of transformation is to widen the side of the trolley to the two sides, the skateboard and the wheels of the trolley remain unchanged, the structure of the wind box is unchanged, the trolley is widened, and the trolley is used in the case that the area of ​​the exhausted air does not increase. The edge effect of the air flow is used during the draft to increase the effective sintering area so that the sintering area is larger than the air drawing area. Through the above transformation, the increase in sintering area is an important means to increase the output of sinter. After the trolley was widened, the corresponding mixing hoppers, bottom hoppers, tube feeders, and multi-roller feeders were all widened and refitted. The specifications of the trolleys for the ignition furnaces were redesigned and transformed, and the investment in these transformations was relatively small.
After the material layer of the sintering machine is raised, the effect of automatic animal heat is enhanced, and the quality of the sinter ore can be improved and the consumption of solid fuel can be saved. Therefore, when the sintering machine is reformed, the height of the trolley bar is increased, and the thickness of the bed is further increased. At the same time, the influence of the air permeability caused by the rise of the material layer can be reduced by adjusting the feeder. Through the modification of the fan starter: The liquid speed control resistor replaces the original frequency sensitive resistor. Not only achieved the full load of the start, while reducing the start-up current, the motor starts more smoothly than before, which also creates conditions for increasing the air volume of the fan. For insurance, the existing foundation must be reinforced. Moreover, the existing liquid-speed regulating resistor can completely satisfy the start-up after the increase of the motor.
In the past several times in the transformation of the sintering machine, because the only consideration is to increase the sintering production, the technical transformation of the cold machine is not much investment, just to adjust the sampan, so it is difficult to meet the current production requirements. Therefore, in order to increase production, it is necessary to improve the ability to bring cold machines. If you increase the length of the cold machine and increase the cooling area, although you can achieve the desired results, there are many changes to the project, and the investment is also very large and difficult to implement. According to the current technological conditions and location conditions and the technological transformation experience of similar plants, it is possible to increase the blower at the bottom with the cold machine to achieve the next drum up pumping method to strengthen the cooling, improve the cooling effect, so as to meet the requirements of the sinter ore production increase.
