摘　　要：以灰铸铁飞轮壳体为例,系统的阐述了消失模铸造的工艺过程和工艺参数。采用阶梯式浇注系统,雨淋式加沙法,浇道比为F内:F横:F直=1.0:1.2:1.4,浇注时负压为0.040～0.055 MPa。浇注温度控制在1 470～1 480℃。生产出的飞轮壳体铸件,石墨分布较均匀,基体组织为珠光体加铁素体,抗拉强度达200 MPa以上。关键词:消失模铸造;飞轮壳体;The article systematically interpreted the process and parameter of lost foam casting,taking gray cast iron flywheel cover for example.Step gating system and raining wise sand filling was adopted.The gating ratio was F内：F横：F直=1.0：1.2：1.4.The negative pressure was 0.04～0.055 MPa during pouring.And the pouring temperature was controlled at 1 470～1 480 ℃.With uniformly distributed graphite,matrix of the flywheel cover casting was pearlite and ferrite.Its tensile strength was higher than 200 MPa.
