Study on Thermodynamics of MgO Based Desulphurizer

Abstract:

For the lacks of magnesium-based desulfurizer in iron and steel industry, this paper investigated thermodynamics calculation of a new desulfurizer, MgO based desulphurizer. The results indicate that the beginning reaction temperature of light-burned dolomite and Al is 1314°C, the beginning reaction temperature of light-burned dolomite and Si is 1565°C, the beginning reaction temperature of MgO and Al is 1475°C, and the beginning reaction temperature of MgO and C is 1846°C. The reaction temperature between MgO and C is too high, so the carbon-thermal reduction can’t occur easier. When the hot iron temperature is 1400°C and the addition of alumnium and iron oxide is 12.77%, the reaction between MgO and C will be induced.
