A numerical model has been used to describe the thermal behaviour of a slab reheating furnace. This universal model has been adapted to fit the case of a walking beam furnace reheating continuous casting slabs for a hot strip mill. Extensive sets of measurements were performed on an industrial slab furnace in order to identify the model coefficients and validate the calculation results. Next, the furnace behaviour was simulated in various cases of hot charging. These simulations were used to calculate effects of hot charging on the energy consumption, the production rate and the efficiency of the furnace. The mixture of cold and hot slabs have also been simulated and the effects on the energy consumption and furnace control are discussed.
