摘　　要：介绍了在消失模铸造生产的各道工序中铸件产生变形的原因以及防止变形的方法。采用控制发泡剂含量和严格模样制作、粘结和组模工序、填砂造型工序和浇注工序中各关键技术措施,使产出的铸件尺寸精度达到了CT10级以上。The reasons causing EPC castings to be deformed in every procedure during production process and measures to avoid deformation was described. The casting dimension accuracy reached CT10 class and even higher by adopting following measures： controlling foaming agent content, strictly controlling wax pattern manufacture, patterns welding and assembling, filling sand and moulding, as well as controlling pouring process.
