摘要

以HBW160床身原有铸造工艺为基础

利用AnyCasting软件模拟了床身的充型和凝固过程

通过正交试验和数值模拟分析

得到床身的最优工艺参数。试验表明

浇注温度对模拟结果的影响最大

然后是冷铁厚度和充型速度。当浇注温度为1 350℃

充型速度为1.78m/s

冷铁厚度为70mm时

铸件内缩松（缩孔）产生的概率最低

铸件质量最好。

Abstract

On the basis of initial casting process of HBW160 machine tool bed

the filling and solidification process was simulated by the AnyCasting software

and the optimized process parameters of the machine tool bed were presented through orthogonal experiment and numerical simulation.The results reveal that the pouring temperature is the main effect factors

followed by the chill thickness and filling velocity.The probability of the shrinkage is reduced to the lowest when the pouring temperature is 1 350℃ with the filling speed of 1.78m/s

and the chill thickness of 70 mm.
