摘要
为了探讨热应力对不同材质构成的高炉炉缸砖衬的破坏作用 ,在计算温度场的基础上 ,应用热弹性理论和有限元法对高炉炉缸进行应力分布计算。计算结果表明 :在用具有不同的导热性能和力学性能的耐火材料砌筑的炉缸内存在着应力集中现象 。
In order to search the demolishing effect of the thermal stress on the hearth and bottom of the blast furnace, the distribution of temperature field and the thermal stress have been studied with the thermal elastic law and finite element method. The results have shown that the concentrated stress area exist in the lining of the hearth and bottom with different firebrick which should be one of the reason eroded the hearth and bottom of the blast furnace.
