摘　　要：为掌握典型工况条件对连铸过程中中间包热损失的影响程度,基于大型数模分析软件ANSYS热分析模块,对普碳低合金钢种连铸中间包热损失影响因素进行了数值分析。结果表明:1)当钢水较大面积暴露在环境中时,环境温度的变化将显著影响中间包钢水温度的变化;2)实际生产中应尽量减少中间包操作孔敞开的时间;3)中间包保温层采用新型隔热保温材料将大幅改善其保温效果;4)覆盖剂的合理选用及正确使用有助于降低上钢温度。In order to grasp the influence of the typical operating conditions on the heat loss in the continuous casting tundish,the numerical analysis on the influence factors of the heat loss in the tundish in continuous casting for the carbonsteel and low alloy steel,based on the thermal analysis module of the software ANSYS,had been carried out.The results showed that,1）The steel temperature could be affected significantly when the molten steel ws exposed to the environment in large area;2）In practice,the opening time of the operation hole on the tundish should be minimized;3） The heat preservation effect in the tundish wounld be improved,if the new heat insulation materials were applied to the insulation on the tundish;4）Reasonable selection and proper use of the covering agent could help reduce the end point temperature of the LF refining.
