摘　　要：分析了铸态珠光体球墨铸铁的形成条件 ,利用正交试验确定了球墨铸铁连杆 Si、Mn、Cu等元素的成分 ,通过研究碳当量对组织性能的影响 ,确定了 C元素的成分。生产试验证明 。The conditions to get pearlite ductile cast iron were analyzed.Chemical composition of Si,Mn,Cu element was given out by means of experiments,and the carbon content was also confirmed by studying the influence of CE on ductile cast iron structure and mechanical properties.The productive tests showed that it was possible to make pitmans using pearlite ductile cast iron as cast instead of malleable cast iron.
