铸态珠光体球铁曲轴生产工艺的研究

Production Technology for Crankshaft made of Cast Pearlitic Ductile Cast Iron

铸态珠光体球铁曲轴的生产过程应严格控制铁液化学成分 ,采用正确的球化处理工艺和瞬时孕育 ,加入适量的铜、锡 ,方可稳定生产铸态珠光体球铁曲轴。

It was concluded from the investigation that the as cast ductile iron crankshaft with the pearlite matrix can be stably produced by controlled compositions,right spheroidization process,instant modification and suitable addition of Cu and Sn
