Description
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.
The chemical composition of pulverized Dolomite supplied by us as follows:
CaO Fe2O3 MgO SiO2
> 30.45% < 0.05% > 19.50% < 0.05%
