摘要
针对异型电渣熔铸件生产过程中出现的熔渣内溢现象,分析探讨了影响此现象形成因素,并从更换电极操作与熔铸工艺进行改进优化,实际生产效果良好.结果表明,更换电极中断功率操作后,供电工艺参数与结晶器冷却强度不匹配是导致结晶器内熔渣溢流的主要原因.
The inward overflow of molten slag appressed to water - cooled copper of electro - slag casting for large - scale castings is very common. In this aritical, we analyse the causes, ameliorate the process of changing electrode and ameliorate the remelting parameters, the actual effect is good. The results show that the unmerited electric power and the cooling technology of water - cooled copper is the main reason of the inward overflow of the molten slag.
