摘　　要：在原有大型立柱铸造工艺基础上,利用Anycasting铸造模拟软件模拟了铸件的充型和凝固过程。根据计算结果和缺陷发生情况,分析了成型过程中铸件的温度场变化和凝固规律。研究结果表明,底部平板未能形成顺序凝固,由于补缩不足容易生成多处缩孔缺陷。优化后在底部平板一侧开设浇冒口工艺,在局部区域形成利于补缩的顺序凝固,解决了缩孔缺陷,满足了实际生产的要求。On the basis of original process of large column casting, the filling and solidification processes were simulated by using software Anycasting. According to the calculation results and the defects, temperature field changing and solidification laws of the castings in molding were analyzed. The results of the study show that the bottom panel failes to form a sequential solidification, because of the insufficient feeding, it is easy to form multiple shrinkage defects. After optimization, casting head process was established on one side of the bottom plate, and beneficial complement sequence solidification in the local area was formed. Shrinkage defects were eliminated, which satisfies the requirements of the actual production.
