Heat exchange during melting of Al - scrap in SAS furnace

Generally, it is possible to increase the efficiency of the plant through the knowledge and improvement of the heat exchange in the working space of the respective aggregate between flue gases - batch - lining. In this paper, the determination of heat exchange in the Al-scrap melting process as a basis for controlling the melting process, based on information on the amount and composition of the scrap in terms of the batch mass, is described. It was explained how to determine the heat transfer coefficient K (W/K) from the data obtained from the operational temperature easurements in the kiln, batch and other necessary parameters of the furnace. The obtained coefficient K is used in the mathematical model of heating and melting in order to determine the expected heating time and melting of Al - scrap from the input data and the kiln operation data.
