Abstract：

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.
