主 题：Reheating Tubular furnace Cast ingot Convective heat transfer Radiative heat transfer
摘 要：Convective heat transfer and radiative heat transfer are two essential heat transfer modes in the heating process of steel;it is important to understand the role of them during the heating process *** effects of the convective and radiative heat transfer during the heating process of a cast ingot in a tubular furnace have been studied by the designed natural and forced convection experiments and mathematical *** heating time for the center of the ingot to reach the furnace temperature is decreased with the increase in furnace *** to the experimental and simulation results,a model is proposed regarding the role of radiative and convective heat transfer in the heating *** low temperature,the convective heat transfer plays a dominant role,while at high temperature,the influence of radiative heat transfer is *** a critical temperature exists between *** forced convective heat transfer can enhance the influence of the convective heat *** critical temperature can be shifted to higher temperatures.
