摘　　要：为降低灰铸铁中合金炉料的成本，针对W（Cu）、W（Mn）两个因子在三个水平上进行了正交试验，优化了灰铸铁中cu、Mn合金的含量。结果表明，将w（Cu）控制在0．4％～0．5％范围，将W（Mn）降低至0．4％左右，在灰铸铁抗拉强度较优的同时降低了合金成本。优化的合金含量在生产中得到了试验验证。In order to reduce the cost of alloy charge in gray cast iron, the contents of Cu and Mn in gray cast iron were optimized by the orthogonal experiment designed with three levels and two factors. The results show that the tensile strength of gray cast iron is optimal when the content of Cu is controlled in a range of 0.4%-0.5% and the content of Mn is decreased to about 0.4%, thus the cost of alloy in gray cast iron is reduced. The optimized alloy contents have been verified in production.
