钢包加盖可以减少钢水热损失,虽然过去也有先例.但是真正实现这一节能措施,还是在近代优质绝热耐火材料问世之后才开始的,过去一个20吨重的包盖,现用轻型耐火材料只用1.5吨就够了。目前,使用效果比较好的一种包盖是 Ladle capping can reduce the heat loss of molten steel, although in the past there are precedents, but the real realization of this energy-saving measures, or in the modern high-quality adiabatic refractories only after the advent of the past a 20-ton cap, light refractory materials Only 1.5 tons is enough. At present, the effect of using a better cover is
