在焙烧电解槽槽底时,砸固缝和阴极碳块之间产生收缩缝,熔体经收缩缝渗到碳块下面,接着碳块上抬,砸固缝裂开,这就是槽底破损的一般过程。槽底破损导致电解槽停槽大修。底部糊捣固操作性质的研究,是在改进的密度测定装置上用冲击法进行的(图1)。 When roasting the bottom of the electrolytic cell tank, a shrinkage crack is generated between the solid crack and the cathode carbon block, the melt infiltrates into the carbon block through the shrinkage slit, and then the carbon block is lifted up to break the solid crack, which is the broken bottom of the tank General process. Slot bottom damage caused cell overhaul. The nature of the bottom paste tamping operation was investigated using the impact method on an improved densitometer (Figure 1).
