高牌号复杂灰铁前端箱体的生产

Production control of complex and high grade of gray cast iron front end box

阐述了从国外引进的前端箱体铸件的铸造工艺,在试生产阶段废品率较高,通过对在实际生产过程中出现的缩松、气孔、漂芯等问题的分析,提出了工艺改进方案,最终显著提高了前端箱体的成品率。

It was expounded casting process of the Front End Box introduced from abroad in this article .The rejection rate was higher in the trial production stage. Through the analysis on the actual production in the process of problem such as Shrinkage, porosity, floating core, etc. the process improvement measures were proposed. Ultimately the casting yield was increased significantly.
