摘要
以石灰石砂生产铸钢件易产生气孔等铸造缺陷。通过对石灰石砂特点进行分析,找出了产生该铸造缺陷的主要原因,提出了相应的工艺措施。生产实践表明,该工艺措施对防止气孔产生,提高铸件质量是行之有效的。
Aimed to the problems of easy engendering casting defects,such as blowholes,in producing castings with limestone molding sand,the characteristic of the limestone molding sand was analyzed.The main reasons for producing casting defects were found out and the related process measures were put forward.The practice shows that the measures are effective,which can prevent the generation of blowholes and enhance the castings quality.
