摘　　要：转炉炉壳寿命主要取决于其应力水平,炉壳工作中承受的应力主要是由于热膨胀和温度不均引起的热应力。本文根据实际转炉建立实体模型。以有限元分析为工具,考虑了炉衬和炉壳材料的物性参数随温度变化的特点和炉衬与炉壳之间膨胀间隙,计算了转炉炉壳在温度载荷和炉衬膨胀压力同时作用下的热应力。所得结果可为转炉炉壳设计提供依据。The life-span of BOF shell directly affect efficiency and cost of steel mill, but this is decided by the stress level , thermal expansion stress and temperature difference stress function BOF shell when it is tasking.Based upon actual BOF,the esolid model is set up.Considering lining and shell physical constant change with the temperature,the thermal-stress of sheel is getted with finite element method in different temperature-load and lining expansion pressure. The result can provide reference for the shell of BOF design.
