摘　　要：以合金化炉冷却段为研究对象,建立了合金化炉冷却段内空气流动与热交换的物理与数学模型,利用Fluent软件,采用标准k-%湍流模型,对合金化炉冷却段内气体流场和温度场的分布进行了模拟,得到了炉内温度及速度分布特征。计算结果表明,数值仿真的结果与现场所测数据基本吻合,且冷却段内气体流动均匀,带钢表面冷却效果良好,对了解合金化炉冷却段的温度分布有一定的指导意义,并为合金化工艺参数的优化奠定了基础。Taking the cooling zone of galvannealing furnace as research objects, physical and mathematical models for the flow and heat transfer of the cooling zone are established. The flow field and temperature field distribution inside the cooling zone of galvannealing furnace is simulated by using Fluent software via a standard k- ε turbulence model, and temperature and velocity distribution of the furnace is obtained. The result shows that the air velocity is homogeneous and the cooling effect in the surface of strip steel is good, which is similar to the practical condition. This method has certain reference value for the research of the temperature field distribution in the cooling zone of the galvannealing furnace, and lays the groundwork for the optimization of the alloying process.
