球墨铸铁机体缩孔分析和防止

Analysis and prevention of shrinkage in ductile iron diesel body

介绍了球墨铸铁机体的铸造工艺,针对生产过程中热节位置孔洞类铸造缺陷的特征和出现规律,对铸造缺陷性质进行了判定,并采取了相应工艺措施。经生产验证,该工艺措施有效,达到了消除缺陷的目的。

The casting process of the ductile cast iron diesel body has been introduced.Aiming at the characteristics and appearance rules of the hole casting defects at the hot spot position during the production process,the nature of the casting defects has been judged,and corresponding process measures have been taken.After production verification,the process measures are effective which achieves the purpose of eliminating defects.
