As a flux for smelting iron and steel, the dolomite can neutralize the acidic slag, improve the alkalinity of the slag and reduce the activity of FeO in the slag, so as to reduce the erosion of the furnace lining. About 170kg dolomite is needed to produce 1t steel.
When adding dolomite to iron smelting, the slag can be diluted, the melting point of slag can be reduced, the fuel consumption can be reduced, and the quality of pig iron can be improved.
