摘要
为提高滚轴碎煤筛选机筛片生产的成品率,采用消失模铸造工艺代替传统砂型铸造工艺。从铸造工艺参数设计与改进及热处理工艺等方面介绍了筛片的消失模制备工艺技术,分析并解决了筛片内部出现气孔、夹渣及粘砂等缺陷问题。结果表明,采用消失模铸造工艺制备筛片工艺技术简单、产品成品率高;生产效率是砂型铸造的1.5倍,产品成品率是砂型铸造的1.25倍。
In order to improve the yield of the screens of roller type coal crushing machines, the traditional sand mold casting process was replaced by the evaporative pattem casting （EPC） process. The casting technology of EPC process for the screens was introduced, including the design and optimization of casting process parameters and heat treatment process. The problems of blowhole, slag inclusion and buming-on defects were analyzed and solved. The results show that the technological process of screens produced by the EPC process is simple and the product yield is high; the production efficiency of EPC process is 1.5 times that of the traditional sand casting process, and the product yield is 1.25 times.
