ABSTRACT:
Product for desulfurization of liquid cast iron composed of technical calcium carbide powder, to which may be added products intended to cause gaseous release in the bath and to modify the composition of the slag and which is coated or agglomerated either by resins or an organic compound having a clear-cut melting point and which is solid at ambient temperature. The process comprises mixing of the carbide and additives with the binding agent, resin, or organic product, agglomeration by pellet formation, compression or extrusion, and possible second grinding and sifting to obtain the desired granulometry. The product is added to the liquid cast iron using a lance, by gravity, or as a filled wire. It has good pourability, increased effectiveness, and reduced reactivity to moisture. It is used for desulfurization of both forge and foundry pig iron.
