Abstract


The quality of calcined aluminum reduction cell electrolyzer tank life has a great impact of the current general domestic use liquid aluminum roasting and baking method electrolyzer coke calcining the uneven heating due to thermal shock and other reasons, the aluminum reduction cell of life is greatly shortened. In this paper, the research status at home and abroad related fields , in 75kA Prebake Aluminum roasting on a new method of high-temperature gas research . Major research and study are as follows: 1 for the conventional calcination method has the disadvantage , the development of high-temperature gas tank 75kA aluminum roasting apparatus . 2 by the method of mathematical modeling distribution chamber combustion devices were simulated according to the flow field and temperature field simulation results for each distribution outlet structure has been optimized . 3 after optimization of the combustion device operation laboratory tests to verify the combustion apparatus has a very good temperature control and temperature and energy balance. 4 aluminum reduction cell will develop high temperature flue gas roasting techniques and devices used in Shanxi Guanlv company 75kA aluminum cell , and achieved good results .
