Abstract

Procedure for deoxidizing or alloying liquid steel with aluminum, which being especially used in a continuous casting system for steel with a continuous supply of aluminum, is essentially characterized by the fact that an aluminum wire lined by a steel, the end of the lined wire being located at the point of incidence of the jet, of liquid steel on the casting container, at a depth, preferably 100 to 150 mm below the level reached by the liquid steel in the container; such that the feed rate and the direction of penetration of the wire are such that the steel shell of the wire melts only at the point of coincidence of the longitudinal axis of the jet of liquid steel with the direction of penetration of the wire.
