冲天炉在熔炼过程中,由于种种原因,其出铁口往往容易“冻结”,严重时不得不停止熔炼,被迫提前打炉,我们在生产实践中,模索出一种修补出铁口的方法,现介绍如下。1.在沿前炉炉底处,设置一个φ80～φ100的大出渣口,这既为打炉时出净残渣和残余铁水,又为修补出铁口创造了有利条件。 Cupola in the smelting process, due to various reasons, the taphole often easy to “freeze”, in severe cases had to stop smelting, was forced to charge the stove in advance, in our production practice, the mold to find a way to repair the taphole Now introduced as follows. 1. In the furnace along the front of the furnace, set a φ80 ~ φ100 large slag hole, which is both a net residue and residual molten iron when the furnace hit, but also to create favorable conditions for taphole repair.
