摘要
对前端板铸件壳型铸造中存在的铸造缺陷，采用优化浇注系统，对铁水进行二次孕育处理，调整碳当量控制在3.90％～4.15％，硅含量降低0.15％～0.20％，使产品抗拉强度≥270MPa，硬度（HB）为187～241，满足用户要求。
The origination of casting defects in the forehand plate of air-conditioner compressor for car in shell mold method was analyzed. The casting defects can be effectively eliminated by optimizing gating system, conducting secondary inoculation for liquid Fe and adjusting content and controlling the chemical composition of liquid Fe, to greatly improve the quality of the forehand plate.
