摘要

针对电渣熔铸钢锭各部位温差大

易产生热应力及测量困难的特点

采用大型有限元分析软件ANSYS

对电渣熔铸过程中不同渣池深度时的钢锭等效应力场进行了模拟研究

得出钢锭最大等效应力与渣池深度之间存在二次函数关系。模拟结果与实际相吻合

运用此模型可预报钢锭应力场状况

对实际生产提供参考。

Abstract

Thermal stress which is difficult to measure easily occurs in electro-slag casting steel ingot due to great difference in temperature at different position.Equivalent stress fields in the steel ingot at different slag pool depths were simulated by the ANSYS software

and the quadratic function relation between the maximum equivalent stress and the depth of slag pool was presented.The simulated results are well in agreement with practical ones

showing the availability of the model.
