摘要： A method for partial reduction in a fluid bed of a fine grained iron oxide containing material whereby a fine grain low sulphur content mixture of partially reduced iron oxide containing material and coke is produced; the coke is obtained from carbonaceous material with a relatively high content of sulphur; accordingly, the combination allows the utilization of carbonaceous materials with a relatively high content of sulfur for the reduction of iron oxide and subsequent production of iron or steel without transferring the sulfur into the final product but separating it therefrom during the partial reduction of the iron oxide.

摘要： The invention relates to a method of combined production of electrical energy and crude iron, comprising reducing iron oxides while keeping the temperature below the melting point of the crude iron during a pre-reduction and above said melting point during a final reduction. The pre-reduction is made by introducing carbonaceous material and the material containing iron oxides into a fluid bed containing solid carbonaceous material, producing reducing gases in the fluid bed by partial combustion of the carbonaceous material with air/or oxygen gas, pre-reducing the iron oxides by said reducing gases until the material has achieved a metallization degree of 30-80 %, most of the heat requirement of the pre-reduction being covered by said combustion. The pre-reduced material is finally reduced and molten by being brought into contact with carbon, and the heat requirement of this final reduction and melting process is covered by electric heating. A substantial part of the exhaust gases from the reduction operations is passed to a thermal power station to generate electrical power therein.

摘要： For the melt reduction of iron oxides, arcs are formed between at least three arcing electrodes in an iron melt, the electrodes being symmetrically positioned about a common vertical axis. The arcs are powered by direct current with the electrodes being cathodic and the melt anodic, and the electrodes are interspaced so closely together that the arcs, due to the direct current powering, converge and form a common focal spot at the electrodes' axis, on the melt, the spot remaining stationary and with any slag on the melt blown away so that the spot is formed by bare metal. Iron oxide material and carbonaceous material, in fine form, is fed downwardly to this spot with the reaction between the oxides and carbon occurring practically immediately.

摘要： A furnace for melting solid ferrous pieces such as pig iron and steel scrap, features a combination of electric induction heating and flame heating of the pieces which are charged into the furnace hearth via a charging stack up through which the products of combustion flow from the furnace counter-current to the descending charged pieces moving downwardly through the stack. The flame heating is via burners supplied with hydrocarbon fluid fuel with oxygen proportioned for incomplete combustion, the products of combustion and unburned fuel ascending through the stack and preheating the descending charged pieces. Air is supplied to the stack to complete the combustion of the previously unburned fuel in and around the descending pieces, this being done at a level where the descending pieces have not yet reached temperatures sufficient to cause excessive oxidation of the pieces. Other details providing for effective utilization of these principles, are included in the disclosure.

摘要： A magnetic separator for a hot mixture has an enclosure with a bottom having means for fluidizing the mixture which travels through the enclosure from an entrance to an exit. Within the enclosure an internally water-cooled drum rotates and which is internally provided with magnetizing means so that magnetic particles in the fluidized flow, into which the drum dips, is picked up and through a suitable discharge carried out of the enclosure, other material in the mixture and which is non-magnetic, discharging from the enclosure. Internally the drum has means for maintaining a body of water in the drum's portion which dips into the fluidized flow, the flow of hot mixture causing the water to vaporize and cool that portion of the drum.

摘要： To reduce metal oxides to molten metal, an electrically non-conductive, annular hearth is used, the hearth being radially corrugated to form radial ridges and valleys. A circumferentially continuous coke bed forming a closed electric circuit, is formed on this bed and heated to incandescence by electric current passed through the bed in its circumferential direction, the current being either induced or applied directly. The oxides in particulated form are fed to this bed for reduction to molten metal, the metal collecting in the valleys of the hearth and thereby being prevented from forming a circumferentially continuous melt of higher electrical conductivity than the coke. Particulated coke and oxides can be fed continuously to the bed, the molten metal being then continuously tapped from the valleys of the hearth to thereby prevent the formation of a circumferentially continuous melt.
