摘　　要：针对具有混合烧嘴的八段步进式加热炉,应用fluent软件建立了炉内燃烧与流动的数学模型。对加热炉内加热特性进行了数值分析。计算模型中包含钢坯和梁,炉内气体的流动和辐射状况更加复杂,符合炉内真实情况。当炉内各个位置的平均温度不改变,认为计算收敛和停止。应用上述模型和算法得到了炉内详细的温度与速度分布。Using the fluent software for the eight step heating furnace with composite burners,a math-ematical model of the combustion and flowin the furnace was established. The of the furnace were analyzed numerically. Calculation of the model of the billet and beamdisrupted the flowand radiation of the furnace gas. It is more accord with the actualthe mean temperature of each position in the furnace does not change, calculation was considered tohave converged and was stopped. The temperature and velocity distributions in the furnace were ob-tained by using the above model and algorithm.
