As we know, the technology which produce iron carbide wilh COREX waste gas has achieved great success, however, the category of valuable exhaust gas is much limited.

Aim to the problem of gas resource scarcity in future development plan at Bao Steel,outside fuels which were introduced to steel works became necessity,and COREX gas in the highest flight.

The further improvements in recycling converter gas are proposed when the effect of introducing COREX gas on the balance of the converter gas system is fully considered.

In this paper, a 2-D static model has been developed to evaluate the gas-solid flow transport phenomena in the COREX smelter-gasifier, application of Computational Fluid Dynamics (CFD) combined with the porous media and multi-phase models are employed.
