摘　　要：用三维造型软件辅助划分刹车头球铁件结构分体并计算模数,按照均衡凝固理论用模数网络分布分析确定均衡段,进而确定该铸铁件的冒口分布方案,用大孔出流理论计算浇注系统,最终确定铸造工艺方案,并设计了完整的铸造工艺。用凝固模拟软件对工艺设计进行了验证校核,实际浇注结果表明,所设计铸造工艺是合理的。Using 3D modeling software, the part of brake head casting was divided and its modulus were calculated. Based on Proportional Solidification Theory, the proportional zones of the casting were determined by the net of the modulus distribution, and then the distribution of risers was planed as well as the foundry technology was plotted. Numerical simulation software was used to verify the technology and the actual pouring result shows the validity of the plan.
