Desulphuriser

The use of calcium carbide based reagents is a long established practice for the desulphurization of pig iron/hot metal resulting in the removal of the sulphur from the molten metal as calcium sulphide into the slag floating on the molten metal surface.

At SA Calcium Carbide desulphurizer reagents are produced by blending calcium carbide with various other additives and milling the mix to a fine powder with a particle size of approximately 95% smaller than 75 microns
