摘　　要：针对某公司大型钢锭的中心疏松和缩孔缺陷,分析了形成机理,提出了应用有限元分析软件对大型钢锭充型、凝固过程数据模拟,进行工艺分析和品质预测,调整钢锭加热工艺,并将得到的两种电加热模式应用于生产,达到了理想的效果。Aimed at the defects of center porosities and shrinkage cavities of large steel ingot produced in a iron and steel Co., the formation mechanism of those defects was analyzed, the filling and solidification process of large steel ingot was simulated using finite element analysis software to analyze the process and predict the quality. The heating process of steel ingot was adjusted according to the simulated results, and two electric heating model are used in production, the desired results were achieved.

关 键 词：钢锭 中心疏松 缩孔 电加热技术
