| The inventions relate to the field of metallurgy, and specifically to a method for producing steel and to a design for an electric arc furnace for implementing same. The method involves loading a charge into a workspace of a furnace, said charge consisting of scrap metal and of agglomerated oxy-carbon materials, inputting electric energy, fuel, a carburizer, a flux and gaseous oxygen, heating and melting the charge using electric arcs with the decarburization of a metal bath, and releasing metal and slag from the furnace. Prior to melting, a portion of the oxy-carbon materials is loaded, simultaneously with a first portion of metal charge, into the central zone of the furnace, and the remaining oxy-carbon materials are introduced into the melted charge during the melting process at a specific loading speed of 0.5-10 kg/min per 1 megavolt-ampere of power of the transformer of the electric arc furnace, and the size of the pieces of oxy-carbon materials is selected to be between 5 and 80 millimeters. The walls of the furnace housing are provided with at least three apertures, which are spaced along the perimeter thereof, for loading oxy-carbon materials into the central zone of the furnace, which apertures are provided 0.2-1.0 meters below the level of an upper mark on the furnace housing. The invention makes it possible to reduce specific electricity consumption when melting metal charge, increase the output of iron from oxy-carbon materials, and also increase the relative quantity of said materials in the overall mass of charge. | ||||||

| Methods for controlling the superheat of the stream of molten metal from an electroslag refining apparatus is taught. The methods include the introduction of unrefined metal into an electroslag refining process apparatus in which the unrefined metal is first melted at the upper surface of the refining slag. The molten metal is refined as it passes through the molten slag. The refined metal is collected in a cold hearth apparatus having a skull of refined metal formed on the surface of the cold hearth for protecting the cold hearth from the leaching action of the refined molten metal. A cold finger bottom pour spout or exit orifice is formed at the bottom of the cold hearth to permit dispensing of molten refined metal from the cold hearth. The super heat of the molten metal flowing through the exit orifice of the cold finger apparatus is controlled, preferably utilizing a processor, such as a computer, by coordinating the rate of induction heat supplied to the metal within the cold finger apparatus and the rate of heat removal from the metal within the cold finger apparatus through the cold finger apparatus itself thereby providing metal having a specific superheat exiting the exit orifice. | ||||||
