The efficiency of aluminium recycling and remelting processes is becoming increasingly important due to the tremendous growth of energy costs in recent years. Modeling the heating and melting behaviour of aluminium can help to better understand the interaction of different heat transfer mechanisms and the limiting factors for the heat exchange in a conventional reverberatory furnace. In the present work heating and melting experiments were carried out in a 500 kg test furnace with a conventional air-fuel burner. Small blocks of aluminium were equipped with thermocouples and insulated on all sides but one to approximate 1-dimensional heat transfer. Numerical heat transfer calculations were compared with the experimental results along with CFD modeling to investigate the contribution of various parameters to the heat transfer into the aluminium ingot.
