    中频炉的炉内留铁水是否对炉壁内衬损害？ 中频炉熔化灰铸铁的，熔化结束后，约三分之一的铁水留在炉内，是否对炉壁内衬的寿命有影响？ 一般来讲是无害的，这主要还要看你的炉壁内衬是什么材料的。 三分之一的铁水太多了 正常情况要看你是多大的炉子 骤热骤冷会对炉子的寿命有影响的 可以留铁水，但不要留太多的铁水。 Does the molten iron remaining in the induction melting furnace damage the inner lining of the furnace wall? When the induction melting furnace melts gray cast iron, about one-third of the molten iron remains in the furnace after melting. Does it affect the life of the furnace wall lining? Generally speaking, it is harmless, it mainly depends on the material of your furnace wall lining. One-third of the molten iron is too much. Normally, it depends on how big your furnace is. Sudden heating and cooling will affect the life of the furnace. You can leave molten iron, but don't leave too much molten iron.
