Abstract

The steel industries have dedicated enormous efforts to increase the efficiency and control of their processes. The sintering process plays an important role producing high quality raw material to the blast furnace and furthermore is a key unit operation regarding to the effective way of recycling residues from the steel industry. In this work a model for simulating the sintering process is proposed taking into account four different phases: Solids( Sinter feed + fines + fine coke), gas, slag and molten metal as well as semi fused iron oxides. The mathematical model considers simultaneously several chemical reactions and phase transformations taking place into the sintering bed. The model is based on the simultaneous solution of the transport equations of mass, momentum, energy and chemical species for all phases. The set of partial differential equations are solved based on the finite volume method in a tri-dimensional domain which allows to determine the position of the reacting zone together with the distributions of temperature, chemical species of the sinter cake, melting rates and several technological parameters.
