摘　　要：风口前端深入高炉内部,其工作环境恶劣,极其容易损坏.为了得到卷焊型风口本体的温度场和冷却水流场,本文利用计算流体力学软件对其进行数值模拟计算.通过模拟发现风口前端Ⅰ水室内存在冷却水流动死区,随后分别讨论了改变流量和优化风口结构对缓解死区的影响.Tuyeres are located deep inside the blast furnace with poor working condition , which are extremely easy to damage. CFD software was used to simulate and get the temperature field and the cooling water flow field of the welded tuyere. Through the simula tion, a flow dead zone was found in tuyere chamber . Then the impact of changing the air flow and optimizing the tuyere structure on alleviating the dead zone was discussed.

关 键 词：数值模拟 温度场 流场 流动死区 优化结构
