간접 가열방식의 연속식 열처리로내 판(Plate)의 전열해석

Abstract

In this study, numerical simulation has been performed by considering the convective and radiative heat transfer to predict the transient thermal behavior of the plate in indirectly-fired continuous heat treatment furnace. The temperature profiles in the plate are determined using transient one-dimensional heat conduction equation. To verify the validity of the present numerical results, the present results obtained from the transient analysis are compared with those of experiments. Extensive parametric investigations are performed to examine the effects of the emissivities of the plate and refractory, charging temperature and residence time of the plate as well as gas temperature of the work side and drive side in a heat treatment furnace, on the thermal behavior of the plate.
