| Abstract: | A mathematical model for numerically simulating the temperature distribution in steel slab in reheating furnace of hot rolling process is developed by using finite difference method.The heat transfer boundary condition of the slab is determined by experimentally measuring the temperatures at different positions in the slab during its reheating process.At the same time,the validity of the numerical simulation is verified by using the experimental data.Moreover,the effects of reheating process on the temperature field of the slab as well as the temperature variation during the rolling waiting interval are studied by using the developed model,which provides scientific foundation for optimizing hot rolling process. |
