Abstract
A charge consisting of scrap, sponge iron, pellets and the like is admitted into a vertically arranged melting chamber and forms a column therein. The leading end of the column is melted with an annular flame generated by means of an annular burner or a plurality of burners arranged circumferentially of the melting chamber. In this manner, a downwardly extending projection is formed within the confines of the periphery of the leading end of the column and this bears against the bottom of the melting chamber thereby supporting the column. An outlet for the molten material is provided in the bottom of the chamber and this is surrounded by a projection extending upwardly from the bottom of the chamber. The latter projection is effective for permitting the molten material to remain on the bottom of the chamber for a short period prior to its outflow from the chamber so that the molten material is superheated by the flame. It is of advantage when the dimensions of the projection in the leading end of the column are maintained sufficiently small to prevent substantial heat transfer from the molten material to the column.
