摘要
Abstract
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.关键词
