Abstract A computational methodology to predict the transient heat transfer to the load in a continuous steel reheating furnace is presented. The procedure couples a numerical solution of the fluid flow and the thermal radiation inside the furnace, obtained using conventional Computational Fluid Dynamics techniques, to a numerical solution for the temperature inside the steel charge. The conduction module solves for the transient heat transfer to the steel slabs, allowing for movement inside the furnace during the reheating operation, using a fine grid embedded in the fluid domain. The full transient problem is simplified by assuming a steady state furnace atmosphere through which a continuous series of identical stock are moving. This procedure allows for an economic solution for the flow field and thermal radiation without losing details of the conduction within the slab. The resulting model has been applied to a three dimensional steel I-Beam moving through a furnace with a predefined gas temperature, uncoupled from the CFD prediction of the flow field. The fully coupled procedure has then been used to study a steel reheating operation for a two dimensional model furnace with rectangular slabs.
