<p>The method concerns production of iron melts, in particular steel out of iron-bearing charge materials (22,29) in a metallurgical vessel (1) with the aid of energy supplied at least partially by a electric arc. A part of the material (22) is introduced into the vessel to form a cone in its central region. A central crater is melted into this cone. The crater is filled with a part of the material (29), which is then melted to produce a crater. This is followed by complete melting of the still solid materials (22,29) before a tapping operation. The plant is provided with separate shafts (21,27) for the iron-bearing charge materials (22,29).</p> |
