According to the relevant information, we can use quartz as flux, and choose quartz stone instead of current white sand (SiO2%: 60%), which can reduce the flux rate, increase the amount of raw materials into the furnace, and reduce the amount of impurities, thus reducing the amount of slag , to achieve the purpose of improving the yield of metal straight.
1. Formulate measures
Blowpipe improvements include:
(1) change shape, change the shape of the straight tube to the shape of an elbow;
(2) Tube coating material formulation and production improvement;
(3) require slag.
2, production practices and results
According to the measures formulated, after the following improvements in the production practice, the management of various technical conditions in the production process of the electrolysis cell is also very important for prolonging the service life of the cell. How to make the operation of the cell under the adjustment of technical conditions? Good electrical, thermal, magnetic, and melt flow characteristics, especially maintaining a stable thermal balance and forming a stable furnace crust, is a priority for production managers and technicians, and also for obtaining the life of the tank. Important link.
3. Some conclusions and suggestions
The problem of aluminum electrolytic cell life is one of the major gaps between China's aluminum electrolysis technology and the international advanced level. It is also an important issue for the development of aluminum electrolysis technology in China. Based on the above discussion, the author puts forward the following conclusions and recommendations:
(1) The factors affecting the life of the aluminum reduction cell are various, involving the electrolytic cell physics, tank lining design and material selection, tank lining construction, roasting start-up and production management, etc. Research should be carried out comprehensively systematically. jobs;
(2) The physical field study is the inherent theoretical basis for extending the service life of the tank. It should be further studied and its application in the electrolytic tank design should be emphasized.
(3) The selection of tank lining structure design and materials is an important part to prevent early leakage of the electrolytic cell, and the in-depth study of the anti-seepage structure and anti-seepage material of the electrolytic cell should be emphasized; (4) The service life of the electrolytic cell With obvious influence, attention should be paid to the management of the electrolytic cell construction, the improvement of construction methods, and strict construction procedures;
(5) The roasting start-up and production management is the final step in the electrolyzer's long life. Improvement of the roasting start-up method and improvement of the production technology level are also crucial for prolonging the service life of the tank.
