Through production practice，during the processing design of splitting con-rod, the forging con-rod quantity produced by splitting of local and imported raw materials were contrasted with different forging heating temperatures and control parameters of cooling rate. The questions found in each link including inside quality inspection, slitting machining test, fatigue test, table and road test were researched and improved. After a series improving of techniques design and process control means, the forging technological parameters and technology standard of splitting con-rod were established to meet the performance index of strength and toughness. The mass production of splitting con-rod with good mechanical properties, brittle fracture feature of fractures and machining ability etc. were realized.
