摘要

在原有SKT大型机床床身铸件铸造工艺基础上

利用AnyCasting模拟了充型和凝固过程

根据计算结果和缺陷发生规律

分析了工艺参数对床身铸件内缩孔率的影响。结果表明

当充型温度为1 300℃左右、充型速度为1.8m/s

冷铁厚度为80mm时

缩孔发生概率最低;浇注试验中

采用优化工艺参数的手段

有效消除了铸件内部可能出现的缩孔缺陷

满足了实际生产的要求。

Abstract

Based on casting process of large SKT machine tool bed

the filling and solidification process were simulated by the Anycasting software.In addition

influences of the process parameters on the shrinkage rate were analyzed according to the simulated calculation.The results show that the lowest casting defects rate can be observed with the filling temperature of 1 300℃

the filling speed of 1.8m/ s

and chill of 80mm in thickness.Through adopting the optimized parameters during pouring process

shrinkage porosities（holes）defects are efficiently eliminated in the SKT machine tool bed

meeting the requirement of actual production.
