高硅钼球铁连接件的潮模砂铸造工艺改进

Green-sand casting process improvement of high silicon molybdenum ductile iron connector

分析了铸件产生缩松、砂孔等铸造缺陷的原因,通过结合生产实际的经验,制定了该类零件铸造工艺的优化改进措施。实施证明,铸件的缩松、砂孔缺陷得到消除,提高了该类铸件的合格率和出品率,降低了生产成本,有极高的经济效益,并可广泛使用。

Analysis are conducted on the root causes of casting defects such as shrinkage porosity and sand inclusion and measures are worked out to improve and optimize the casting process for the part based on the actual production experience. Through implementation it proves that defects of shrinkage porosity and sand inclusion are eliminated and conformity and yield rate of the castings have been improved, and cost has been reduced as well. The method has been approved to have high economic benefit and can be widely used.
