针对某钢铁设计研究院自主设计的150 t转炉,采用系统CAE技术对转炉设备系统进行仿真分析。考虑转炉内工作层逐渐减薄将对温度场及热应力分布产生影响,分别建立了炉役初期和炉役末期的整体CAE模型,通过热分析仿真得到转炉设备系统在工作状态下的温度场分布,作为边界条件之一以进行热-固耦合结构应力分析,得出了不同炉龄下转炉设备在工作过程中的整体温度场,以及热-固耦合应力分布情况,较为精确地校核了转炉的强度条件。
For a 150 t converter independently designed by a steel design and research institute, the system CAE technology was used to simulate the converter equipment system. Considering that the working layer in the converter is gradually thinning, the temperature field and the thermal stress distribution will be affected. The whole CAE model of the initial stage and the end stage of the furnace will be established respectively. The temperature field distribution of the converter system under working condition will be obtained through the thermal analysis simulation , As one of the boundary conditions for the stress analysis of the thermo-mechanical coupling structure, obtained the overall temperature field and the thermo-mechanical coupling stress distribution of converter equipment under different furnace ages, and more accurately verified the converter Intensity conditions.
