A computer program system was developed to simulate the smelting reduction ironmaking process. In this study, the effects of zinc, temperature, and post combustion ratio of the gas generated from the smelting reduction furnace on the behaviour of sulphur in the iron bath smelting reduction process were investigated from the thermodynamic point of view. The simulated results indicated that even a very small amount of zinc could introduce sulphur into the dust in the form of ZnS, which would effectively prevent the sulphur from entering the outlet gas. Moreover the deposited ZnO would accumulate continuously in the system in case of all dust being recycled.
