摘　　要：采用大型商用有限元软件PROCAST,对40 t传统定向凝固钢锭和中空侧壁定向凝固钢锭的温度场和缩孔的分布,以及钢液完全凝固时间进行对比。由数值模拟得出:中空侧壁定向凝固温度场分布合理,能够明显降低缩孔程度及分布范围,进而提高产品收得率及质量。A comparative analysis of the directional solidification process between a 40t hollow-sidewall steel ingot and a 40t traditional steel ingot was done by large-scale commercial FEM software PROCAST in temperature distribution,shrinkage cavity distribution and full solidification time.The simulating results show that the temperature distribution of hollow-sidewall steel ingot in directional solidification is reasonable and the degree and the range of the shrinkage cavity are reduced.The yield and quality of steel ingots improves.
