Abstract: Cone crusher shell is a kind of large steel casting that has complicate shape and high quality
requirements. Through the analysis on its structure, resin-bonded sand mold, insulating riser and the internal
and external chills were adopted after the simulation verification by the CAEINTECAST. Finally the bottom
shell of cone crusher CH660 was produced successfully by fast pouring and normalizing plus tempering
treatment. The result shows that the dimensional precision, the mechanical performance and the surface
roughness are satisfying. The detection test and practical validation results after being installed in a motor
actory show that the performance of the casting satisfies the requirement, which established foundations for
the mass production of the casting

圆锥破碎机是一种用量较大的玻碎设备之一,而
其売体是铸钢件的典型应用,CEI660圆锥破碎机上下
壳体总重16000kg,下売体如图1所示。该件为国内某
厂为国外一家企业制造的配件,采用国际标准和技术
要求,质量要求苛刻。壳体件里面装置各种耐磨衬板、
破碎锥体、电机及传动齿轮,设备运转时震动剧烈
工作环境粉尘大,工作条件比较恶劣,因此对铸件的
表面质量和尺寸精度要求高,若机件因铸造缺陷失效,
不但影响生产,而且经济损失巨大,所以制定合理的
