摘　　要：为防止转炉炉壳因高温蠕变产生过大变形,以有限元为手段,以ANSYS大型软件包为工具,对国内某炼钢厂的大型转炉炉壳在强制空气冷却时的温度场进行了分析.分析结果表明:炉役前期炉壳最高温度为393℃,炉役后期炉壳最高温度为428℃,均未超过炉壳的蠕变温度450℃.因此,强制冷却抑制了高温蠕变,且其冷却方式和冷却部位是有效的.In order to prevent the BOF shell’s large deformation produced due to high temperature creep; based on the finite element method,by means of the large ANSYS software package,the temperature field of the BOF shell being in a domestic steelmaking plant being forced air cooled was analyzed.Analysis results showed that the highest temperature of the shell at the early stage of the furnace life is 393 ℃ and the highest temperature of the shell at the last stage of the furnace life is 428 ℃,which does not exceed the creep temperature 450 ℃ of the shell.Therefore,the forced cooling suppresses the creep at high temperature,and the cooling method and cooling position are effective.
