一、前言冲天炉熔炼是铸造过程的主要工序之一,它既影响铸件材质的性能,又直接决定了铸造的经济效益。而配料义是熔炼中的一个关键。过去和现在使用的手工配料计算的落后性表现在:(1)只考虑化学成分,根本不顾及成本;(2)不能适应炉 I. Introduction Cupola melting is one of the main processes in the casting process, which not only affects the performance of the casting material, but also directly determines the economic benefits of casting. The sense of ingredients is a key in smelting. The backwardness of past and present manual ingredient calculations is manifested in the following aspects: (1) chemical composition alone, without regard to cost; (2) incompatible with furnace
