化学成分变化对铸铁管球化品质影响的研究

Influence of Chemical Composition Change on Spheroidization Quality of Ductile Iron Pipe

在实际生产的条件下 ,研究了小口径球墨铸铁管在球化后主要化学成分的分布和变化对铸态球化效果的影响 ,并对铸管存在的球化衰退进行了分析 ;根据试验结果 ,提出了对成分及工艺条件进一步的改进措施。

In this paper,the essential chemical composition on the spheroidized quality of small sized ductile iron pipes have been investigated,and the degeneration of spheroidal graphite in ductile iron pipe was analyzed,under practical manufacturing condition And more,some improved measures in regard to composition and process parameters have been brought forward.
