摘　　要：通过蠕铁材料试验,找到了蠕化剂和合金的合理加入范围,保证蠕化率可以在85%左右,抗拉强度达到RT450。采用快速铸造的方式开展蠕铁缸体的试制,经解剖分析,蠕铁缸体本体的蠕化率在80%~90%,抗拉强度大于450 MPa。Through the test of vermicular iron material, this paper finds out the reasonable addition range of vermicular agent and alloy to ensure that the vermicular rate can be about 85% and the mechanical properties can reach RT450. The trial production of vermicular iron cylinder body is carried out by rapid casting. Through section analysis, the vermicular rate of vermicular iron cylinder body is 80%-90% and the mechanical properties are more than 450 MPa.
