生产0.4t、平均壁厚48mm的钢锭模,常在冲天炉炉料中配入约50%的铸造生铁、45%的回炉料和5%的废钢。使用这种炉料的钢锭模寿命约为48次。浇注1t钢锭需消耗33.3kg钢锭模。已完成的研究指出:钢锭模寿命不高的主要原因是含碳量偏低(≈3.35%),与最佳含量(4.1%)相差很多。因此,在生产 Production 0.4t, average wall thickness of 48mm steel ingot mold, often in the cupola charge with about 50% of cast iron, 45% of the back charge and 5% of the scrap. The life of a steel ingot using this charge is about 48 times. Pouring 1t ingot requires 33.3kg ingot mold. The completed research indicates that the main reason for the poor life of the steel ingot mold is the low carbon content (≈3.35%), which is quite different from the best content (4.1%). So in production
