采用有限元分析技术,通过热-结构耦合的数值模拟方法分析比较了高炉炉腹区域铸铜冷却壁的进水管凸台改进前后的温度场、应力场及热变形情况,证明了进水管凸台结构改进后的铸铜冷却壁具有更好的冷却性能和更低的破损概率。然后以改进型铸铜冷却壁为计算模型,对影响其温度场和应力场的相关因素进行进一步的数值模拟,以优化铸铜冷却壁的结构。 The temperature field, stress field and thermal deformation before and after the inlet bushing of cast-copper stave in blast furnace bosh area were analyzed and compared by the method of finite element analysis and numerical simulation of thermo-structure coupling. It was proved that the inlet bosses The improved cast-iron stave has better cooling performance and lower probability of damage. Then, the improved cast copper cooling wall is taken as the computational model to further simulate the relevant factors that affect the temperature field and the stress field to optimize the structure of the cast bronze cooling wall.
