石油装备钩体的铸造工艺改进

Improvement of Casting Technique of Hook Used on Petroleum Equipment

钩体属于石油装备关键零部件。针对原工艺容易出现的严重缩松和夹渣问题,根据生产经验,提出三种工艺改进方案,借助计算机模拟技术,找出了一种合理的工艺方案。实践表明,该方案不仅解决了缩松、夹渣问题,而且铸件质量稳定。

Hook is the key part of petroleum equipment.According to the casting defects such as dispersed shrinkage,slag inclusion etc of the original technique,three improved casting techniques were put forward on the basis of production experience,a reasonable casting technique was determined by computer simulation technology.The practical production shows that the casting defects such as dispersed shrinkage,slag inclusion etc.were eliminated with the improved casting technique,and the casting quality was stable.
