From the viewpoints of the limited deposit of natural resources and the protection of global environment, utilization of iron scrap is strongly requested. For estimating the effectiveness of the moving bed type scrap melting furnace, a two-dimensional mathematical model has been proposed, which considered transport phenomena of heat, mass and momentum together with melting and chemical reactions in the furnace for iron scrap melting. Numerical simulation was conducted to investigate in-furnace phenomena and effects of operating conditions on the process stability. According to the numerical results, the blast preheating was very effective for reducing coke consumption, because the coke rate can be reduced to 200 kg/t when it preheated to 673 K without oxygen enrichment. As the results, the process characteristics such as distributions of gas concentration, temperature and velocity have been obtained; they are useful to evaluate the performance of the iron scrap melting furnace and to improve the operations leading to less energy consumption and more iron scrap melting.
