摘要
分析了铸态珠光体球墨铸铁的形成条件,利用正交设计确定了球墨铸铁连杆Si、Mn、Cu等元素的化学成分,通过研究碳当量对组织性能的影响,确定了C元素的化学成分。生产试验证明,球墨铸铁连杆件可替代进口可锻铸铁件。
The formation condition of as-cast pearlite ductile iron was analyzed.The Si,Mn and Cu contents of ductile iron connecting rod was determined by experiments designed according to the orthogonal method,and the carbon content was determined by investigating the influence of carbon equivalent on the structure and mechanical properties.The production experiment proved that ductile iron connecting rod could be used as the substitute for the imported malleable iron casting.
