目前世界铝工业的发展趋势是采用大容量预焙阳极电解槽。国外这种电解槽的寿命一般为4~5年。我国大型预焙阳极电解槽的寿命,就某铝厂大型试验场所进行的四台槽七个槽次的试验来看,除2~#槽和1~#槽第二槽次寿命较长以外(2~#槽运行五年,1~#槽运行二年,在因故停槽及刨炉时均未发现破损);其它槽次寿命均较短,一般为一年左右。就系列化试验槽来看,在生产的两年半中,陆续破损的占73.9%,其中已停槽大修的占47.8%。上述情况说明:我国,大型预焙槽的寿命问题,是一个必须认真研究和解决的问题。
The current development trend of the world aluminum industry is the use of large-capacity prebaked anode cell. The life of this cell abroad is generally 4 to 5 years. China’s large prebaked anode cell life, a large aluminum test site for the test of the four slots of seven slots, in addition to 2 ~ # slot and 1 ~ # slot second slot life longer 2 ~ # slot run for five years, 1 ~ # slot run for two years, in some cases when the slot and planing furnace were not damaged); other slot life are shorter, usually about a year. In the series of test tanks, in the two and a half years of production, 73.9% were gradually damaged, of which 47.8% were overhauled. The above situation shows that the problem of the life span of large prebaked reservoirs in our country is a problem that must be seriously studied and solved.
