Abstract
A charge including scrap, sponge iron and ferrous metals is admitted into the top of a vertically arranged melting column and descends through the latter by gravity. The charge is melted by directing a flame against the leading end thereof and the melt flows through an outlet at the bottom of the melting column in to a chamber located beneath and communicating with the melting column. In this chamber, reduction of the slag is effected and the slag is removed from the molten metal. Alloying additions and deoxidizing agents are introduced into the chamber so that the molten metal is deoxidized and becomes alloyed to produce steel having a desired analysis. The thus-produced steel is superheated in the chamber and is then continuously cast.
