冲天炉的材料平衡,是检验与分析熔炼过程的主要方法。所有加入冲天炉中的各种材料与熔炼时所得产品的化学分析,以及衡量的结果,是组成冲天炉平衡的原始资料。铁水主要是由铁料熔化而得,但亦吸收了极少量焦炭中的碳、硫和磷。 Cupola material balance, testing and analysis of the main method of melting process. The chemical analysis of all the materials added to the cupola and the products obtained during smelting, as well as the measurement results, are the raw materials that make up the balance of the cupola. Hot metal is mainly melted from iron, but it also absorbs very small amounts of carbon, sulfur and phosphorus in coke.
