摘　　要：某转炉托圈在使用过程中炉壳和托圈的间隙为45mm,该厂提出对炉体和托圈进行重新设计,并扩容至120t,为准确反应托圈及联接装置的变形,采用有限元法进行分析。首先准确模拟托圈的温度场,基于托圈温度场仿真结果,然后利用顺序耦合方法,计算托圈在热应力作用下的变形。变形结果表明,托圈与炉壳的间隙距离满足要求,但在使用时必须做好托圈和炉壳的冷却工作。The gap between furnace shell and trunnion ring is 45mm in the course,the plant proposed furnace body and the trunnion ring redesigned and expanded to 120 tons.In order to accurately reflect the deformation of the support ring and the coupling device,this paper uses the finite element method to analyze.Based on trunnion ring temperature field simulation results and use sequential coupling method,the temperature field results in the form of heat load reads structural analysis.Calculate the deformation of trunnion ring under thermals tress.The results show that although the gap between the furnace shell and trunnion ring meet the requirements,the furnace shell cooling work must be done.
