高炉炉腹区域铸铜冷却壁的数值模拟及结构优化
|
摘要
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。
Using the method of finite element analysis techniques and thermal-structural coupling numerical simulation,the temperature field,thermal deformation and stress field were analyzed and compared between BF bosh cast copper cooling walls before and after optimization of inlet pipe bosses.The results show that cast copper cooling wall in which the inlet pipe boss structure was improved will have a better cooling performance and lower probability of breakage.Then taking the improved cast copper cooling wall as calculation model,the temperature field and stress field in inlet pipe boss was further numerically simulated to optimize and analyze the structure of cast copper cooling wall.
