摘　　要：根据热流体力学原理和计算流体力学热焓-多孔介质方法,建立了包含铁水凝固相变的高炉炉缸三维稳态出铁数值计算模型.计算中采用等效对流换热系数的方法对炉缸、炉底的冷却条件进行了合理转化.结合实际高炉炉缸对其流场、温度场和渣皮形貌进行了数值计算和分析.给出了不同高炉容积利用系数和冷却条件下的炉缸铁水流动特征和结渣情况数据,可为现场操作提供技术参考.According to the thermofluid dynamics and enthalpy-porosity method of computational fluid dynamics, a 3-D steady-state tapping model of blast furnace hearth was developed, including solidification and phase transition of hot metal and slag. The cooling conditions for hearth and bottom were transformed reasonably by equivalent coefficient of convective heat transfer. The velocity field, temperature field and skull figure in a blast furnace hearth were computed and analyzed. The skull data and flow character of hot metal were given under conditions of different utilization factors of blast furnace and cooling intensities, thus providing the reference for blast furnace operation.
