【摘要】 利用有限元分析软件ＡＮＳＹＳ对冷却壁高炉炉墙的温度场进行了数值模拟，研究了不 同的砖衬材质及其侵蚀程度对炉墙温度场的影响．并在此基础上探讨了高炉炉身下部破损的 基本原因及过程．结果表明：冷却壁凸台的冷却能力不足导致了凸台前砖衬热面温度始终高于 其受化学侵蚀的临界温度，不可能存在稳定的砖衬层．更多还原

【Abstract】 With the finite element analysis system ANSYS, the temperature field in blast furnace wall, cooled with flanged stave system, was numerically simulated. The influence of the refractory kind and its wear extend was’ investigated, and the principal reason and process of wear of the blast furnace lower shaft wall was discussed. Analytical results show that the insufficient cooling capability of the stave flanged part results in the maximum temperature on the lining hot face is always higher than its chemical erosion critical temperature, and no equilibrium thickness lining could be kept steadily on the front of flanged part of the stave.更多还原
