采用有限元模拟方法,计算了不同耐火材料配置条件下炉缸炉底的温度场分布,提出了一种有别于散热型和隔热型的炉缸炉底结构——改进型炉缸炉底结构。在改进型炉缸炉底结构中,将炉底耐火材料导热系数由内至外从10 W/(m·K)逐步提升至40 W/(m·K),可在炉底工作面形成凝结层,保护炉底,从而延长炉底部位耐火材料的使用寿命。 The finite element simulation method was used to calculate the temperature field distribution of hearth and furnace bottom under different refractories configuration. A hearth hearth structure different from heat-dissipating and heat-insulating type was proposed structure. In the improved hearth bottom structure, the thermal conductivity of the refractory in the bottom of the hearth is gradually increased from 10 W / (m · K) to 40 W / (m · K) from the inside to the outside, which can form a condensation on the bottom of the hearth Layer, protect the hearth, thereby extending the life of refractory material at the bottom of the furnace.
