摘　　要：利用有限元法计算了炉缸壁3种模型的温度分布及热应力分布,得出结论:将高炉炉缸壁简单地看作轴对称体进行温度、应力的计算,存在较大的误差。提出了将三维炉缸壁简化为二维炉缸壁进行温度、热应力计算的新方法。此方法不仅适用炉缸、炉底的数值计算,也适用高炉炉体的数值计算。The temperature distribution and thermal-stress distribution of three models for blast furnace hearth （BFH） were calculated by using finite element method. It is concluded that the computed result of the temperature and thermal-stress has wider error if BFH is regarded as axisymmetric body. A new method that three-dimensional BFH model simplified as two-dimensional BFH model is proposed. This new method appropriates not only for numerical ealculation of BFH, but also for that of blast furnace body.
