摘要: 基于坯壳应力遗传特性建立铸坯热力耦合模型，利用ANSYS对结晶器内铸坯传热及应力进行数值模拟，对比分析结晶器磨损前后坯壳厚度、表面温度和气隙分布规律。结果表明：结晶器在磨损之后，偏离角部附近形成“热点”区域。气隙分布范围由距角部10 mm扩展到80 mm，最大厚度由0.1 mm增加到1.2 mm。

Abstract: Based on the genetic characteristics of stress in the solidified shell,a coupled thermo-mechanical model for strand was established.Heat transfer and stress analysis on the strand in mould were completed by ANSYS.The shell thickness,surface temperature and air gap distribution were contrasted between new and worn moulds.The results suggested that the hot pot would appear apart from the corner area after mould was worn.Air gap distribution area extended from 10 mm to 80 mm apart from the corner.The maximum thickness increased from 0.1 mm to 1.2 mm.
