摘　　要：采用ProCAST仿真软件对ZTAp/高铬铸铁基复合材料在浇注温度为1 350、1 450、1 550、1 650℃,浇注速度为3.0、3.5、4.0 kg/s下进行应力场模拟,并通过试验对模拟结果进行验证。结果表明,在砂型重力铸造下,不同的浇注速度和浇注温度的蜂窝预制体所受到的应力分布是不一样的,在浇注速度为3.5 kg/s、浇注温度为1 550℃时的预制体的受力较为均匀,在复合材料中复合效果较好,并且能够保证预制体在复合过程中有良好的结构完整度。ProCAST casting simulation software was utilized to simulate the stress field in ZTApreinforced high chromium cast iron(HCCI) matrix composites at different pouring temperatures of 1 350, 1 450, 1 550 and 1 650 ℃, and pouring speeds of 3.0, 3.5 and 4.0 kg/s, and the simulation results were experimentally verified. The results indicate that under the condition of sand gravity casting, the honeycomb preform suffers different stress distribution at different pouring speeds and pouring temperatures. The stress on the preform at the pouring speed of 3.5 kg/s and pouring temperature of 1 550 ℃ is more uniform, presenting better composite effect of the composites, and desirable structural integrity of the preform can be guaranteed during the compound process.
