摘要：

为了考察炉底辊内冷却水流速能否满足工作要求，利用Solidworks建立了用于中板常化处理的加热炉炉底辊模型。采用Fluent软件的RNG k-ε湍流模型和energy能量模型，模拟了炉底辊内部冷却水在不同水流速度和不同初始温度下的流动状况，对比了不同冷却水流速下辊身的温度，得到了不同流动状态下冷却水流场和炉底辊温度场的特性。研究结果表明：合理的冷却水流速和入口温度，可以提高炉底辊的使用寿命，从而能够节约工业炉的生产成本。现场采集的温度监测数值与温度模拟值相差很小，故采用本文仿真模拟方法可进一步优化辊底式加热炉炉底辊。

In order to meet the working requirements for internal cooling water flowing velocity of furnace roller, the model of the furnace roller plate for normalizing heat treatment was established by Solidworks. The RNG k-ε turbulence model and the energy model in software Fluent were used to simulate the flow condition of internal cooling water of furnace roller at different water flowing velocities and initial temperatures. The roller body temperatures at different cooling water flowing velocities were compared, and the characteristics of cooling water flow field and temperature field of furnace roller were obtained under different flowing conditions. The results show that the service life of furnace roller can be improved by reasonable cooling water flowing velocity and inlet temperature, so the production cost of industrial furnace can be reduced. The difference between monitored temperature on site and simulated temperature is little, therefore, the roller hearth type heating furnace roller can be optimized further by the simulated method presented in this paper.
