| Abstract: | 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. |
