• COREX is the first industrially proven smelting reduction process in the world. In this paper, a static model has been developed based on mass and heat balances. Further, a zoned model for the melter-gasifier was established on the basis of the static model. The model is capable of calculating the consumption of iron ores, coal, fluxes, the volume and composition of the slag and the volume and composition of the reducing gas from melter-gasifier. The model enables the examination of the changes of material and heat flows induced by the variations of operation parameters and raw materials chemical compositions. The model allows optimization of operation parameters of the COREX process, which can thus be used to improve the plant operation under different conditions.
