摘　　要：运用ProCAST软件对ZG30SiMnMoV钢履带板铸造凝固过程进行了模拟,分析了铸件的缺陷受浇注温度的影响情况和铸件的有效应力受浇注速度、浇注温度的影响情况,并进行了试验验证。结果表明,当浇注温度为1610℃时,履带板内部的缩孔、缩松缺陷明显减少;铸件的有效应力受到浇注速度的影响不大,适当地降低浇注温度可显著降低铸件的有效应力,可以得到品质良好的铸件。ProCAST software was adopted to simulate the casting solidification process of the vulnerable caterpillar board.The effect of pouring temperature on casting defects and pouring rate and pouring temperature on the valid stress of the casting were analyzed,and the experimental verification was carried out.The results demonstrate that the shrinkage cavity and porosity defects in the caterpillar board are obviously reduced when the pouring temperature is 1610℃.The valid stress of the casting is hardly affected by the pouring rate,which can be significantly reduced by appropriately reducing the pouring temperature,thus resulting in good quality of castings.
