In order to search the demolishing effect pf 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.

• 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。
