VERFAHREN UND VORRICHTUNG ZUM HERSTELLEN VON EISENSCHMELZEN IN EINEM HERD-SCHACHTOFEN

摘要

The method concerns production of iron melts, in particular, steel in a metallurgical vessel (1) out of iron-bearing charges with the air of energy supplied at least partially by an electric arc. Such charges are divided into scrap I (22) and scrap II (29) respectively with low and high proportions of organic constituents. A charge consisting at least partially of scrap I is loaded into the vessel form a cone. A central crater is melted into this cone by means of electric arc energy. The crater is filled with a charge consisting at least partially of scrap II, and a central crater is again melted into the cone. This is followed by complete melting of the charge materials (22,29) and a tapping operation. The vessel (1) is provided with means (21,27) for separate introduction of charges with low and high proportion of organic constituents.
