电解铝阳极炭块溶液浸渍优化处理

Optimization and Treatment on Electrolyze Aluminum Anode Carbon Lump

阳极炭块优化处理的目的是降低炭块孔隙率 ,提高其抗氧化性能 ,降低阳极消耗 ;提高阳极炭块的导电率 ,降低电耗 ,提高经济效益和改善环境质量。溶液浸渍处理法 :阳极炭块先用AlCl3 溶液浸渍 ,再用氨水浸渍 ,然后在 95 0℃进行焙烧处理。研究表明 :影响阳极炭块优化处理质量的主要因素是焙烧时间、溶液浓度和浸渍时间。采用AIIBIICIII条件优化处理的阳极炭块与空白阳极炭块相比 ,填充率达到 19.0 6% ,电阻率降低幅度高达 34 .2 4 %。

How to reduce to small opening ratio and to increase resist oxidation capability and to reduce consume of anode carbon lump, as well as how to improve to electric conductivity ratio and to reduce electric power consumption of anode carbon lump and to increase economy benefit is main purpose on optimization and treatment on electrolyze aluminum anode carbon lump. Immersion method is introduced. Electrolyze aluminum anode carbon lump is soaked by AlCl 3 solution at first, then it is soaked by ammonia, it is treated by roasting at 950℃.The results show: The main factors affecting the quality of electrolyze aluminum anode carbon lump are roasting time ,solution concentration and immersion time. It's fill ratio is 19.06% , the range of resistance ratio descending is 34.24% under A II B II C III condition comparing to without treatment.
