钢锭模的消耗约占钢成本的1.5～3%,假如不计炼钢原材料的成本,那这数值是炼钢总加工费的8～10%。同时在冶金工业中钢锭模的需要量很大,它的产量甚至能占整个铸铁件产量的十分之一。因此提高钢锭模的寿命,降低其消耗数量,具有很大的国民经济意义。例如年产两千万吨钢,每年就需要 Steel ingot mold consumption accounts for about 1.5 to 3% of the cost of steel, if not including the cost of steel raw materials, then that value is the total cost of steel processing 8 to 10%. At the same time in the metallurgical industry needs a large amount of ingot mold, and its output can account for even one-tenth of the entire cast iron production. Therefore, increasing the life of ingot mold, reducing the amount of consumption, with great national economic significance. For example, an annual output of 20 million tons of steel is needed on an annual basis
