PCT No. PCT/IT95/02223 Sec. 371 Date Jul. 3, 1997 Sec. 102(e) Date Jul. 3, 1997 PCT Filed Dec. 20, 1995 PCT Pub. No. WO96/21046 PCT Pub. Date Jul. 11, 1996This invention covers the method and equipment for the continuous or discontinuous addition of reaction/inoculation materials necessary for desulphurization or the production of ductile iron obtainable during the passage of the base iron through a basin containing the chamber for melting, vaporizing and distributing the reaction-inoculation materials into the melt (e.g. magnesium vapor-Ferrum Silicon). The treatment can be conducted continuously for unlimited or freely definable quantities of iron.
