在总结新建 190kA预焙槽系列焙烧启动实践基础上 ,指出采用焦粒焙烧 ,相邻槽间分流 ,干法启动等措施 ,具有提升电流速度快 ,分流器分流量大 ,冲击电压低 ,焙烧时间短 ,焙烧过程阴阳极电流分布均匀 ,操作简单 ,启动速度快且平稳 ,炭渣分离良好 ,电解质不含碳等优点 ,且从第 10d开始更换阳极 ,延长启动期阳极碳块使用时间 ,减少工人劳动量
On the basis of summarizing the roasting start-up practice of newly built 190kA prebaked cell series, it is pointed out that using coke grain roasting, shunting between adjacent trenches and dry start-up and other measures have the advantages of fast current rise, large diverter shunt, low impulse voltage, Short and roasting process, the anode and cathode currents are evenly distributed, the operation is simple, the startup speed is fast and stable, the carbon residue is well separated, the electrolyte does not contain carbon and the like, and the anode is replaced from the 10th day to prolong the use time of the anode carbon block in the start- Labor
