摘要： A process and device are disclosed for melting scrap in a direct current-driven closed shaft furnace. The scrap is fed in a ring area at the furnace end, the hot gases which flow against the falling scrap are sucked below the scrap feeding area by the cylindrical outer wall of the scrap column, and the inner free surface of the ring-shaped flat cross section is reduced before the scrap reaches the melting zone. In the melting zone, the scrap is exposed to the electric arc at the center of the flat cross section. The arc furnace is designed in such a way that the cathode (21) is held by the electrode bearing device (30) designed as a concentrical pipe (31) with respect to the central axis (I) of the vessel. At its head end, the pipe (31) is conically tapered (34) and at its bottom end it is supported on the shaft (11) by bearing arms. A flue gas channel (19) which surrounds the shaft (11) is provided at the head of the shaft furnace (10).

摘要： A process for the continuous production of an iron-carbon alloy utilizing an enclosed reactor (10) capable of limiting the ingress and egress of atmospheric gases and gas reaction products respectively. A solid mineral material (20) containing iron carbide and at least trace amounts of iron oxide, and having a weight ratio of at least about 2:1 or greater, is fed into a molten bath (12) of metallic material in the reactor (10). The molten metallic material is simultaneously reacted with oxygen at a temperature sufficient to generate carbon monoxide as a reaction product. The oxygen is preferably injected into the molten metallic material to facilitate the reaction of the oxygen with carbon from the iron carbide to form the carbon monoxide. The carbon monoxide subssequently enters a vapor space (17) of the reactor (10) above the molten bath (12), and further reacts with oxygen to generate carbon dioxide and heat. Products of the described method are also disclosed including a continuous supply of molten iron-carbon alloy. The system or equipment utilized in the present process is also disclosed.

摘要： The method provides for placing a plane workpiece (1) in its initial position horizontally between cooled beams (2 and 3) of a crystallizer. Plasma-arc burners (6) are placed in a row above the workpiece (1) and across its parallel edges (1a and 1b) so that the anode spots of the extreme burners (6a and 6b) are limited by the edges of the workpiece (1). A plasma-arc generating gas and electric current are fed to the plasma-arc burners (6), the workpiece thus being heated and a bath (8) of molten metal being produced on it, its length being equal to the distance between the edges (1a and 1b) of the workpiece (1). The workpiece (1) and the plasma-arc burners (6) being moved in relation to each other in a horizontal plane and along the edges (1a and 1b) of the workpiece (1), the displacement of the bath (8) of the molten metal is thus ensured along the surface of the workpiece (1). As a result a remelted surface layer is obtained on the workpiece its thickness being equal to the depth of the bath (8). A device implementing this method comprises a pressurized chamber (11) and a crystallizer mounted therein and including two beams (2 and 3) which are oriented in a horizontal plane and are parallel to each other. Plasma-arc burners (6) connected through supply lines (12, 13, 14) to sources of a plasma-arc generating gas, of electric current and cooling water are mounted inside the chamber (11) on shafts (17). Each of the shafts (17) is mounted by means of a seal bushing (18) in the wall of the chamber (11) so that its axis is parallel to the beams (2, 3) and is provided with a drive (24) for its own axial rotation. The device is further provided with a drive for reciprocal displacement of the workpiece (1) and the shafts (17) in a plane parallel to the beams (2, 3), that drive being connected with at least one of the elements participating in the said displacement.

摘要： A process for improving the rate of metal production and FeO utilization in a steelmaking process or a process combining ironmaking and steelmaking in a single reactor that uses or generates Fe-C metal alloy droplets submerged in an FeO-containing slag. The process involves discharging a charge build-up (electron accumulation) in the slag at the slag-metal alloy interface by means of an electron conductor connected between the metal alloy droplets and a gas at a gas-slag interface, said gas having an oxygen partial pressure of at least about 0.01 atmosphere.
