摘要： A method for reducing molten raw materials, includes placing the raw materials, in a solid or molten state, on an inductively heated bed with coke pieces. The reduced melt that runs off the coke bed is collected and the waste gases are discharged. A coke bed is inwardly limited by a tube-shaped element through which the reaction gases are drawn off via a plurality of draw-off openings in the tube-shaped element. The corresponding device has a reactor for a bed with coke pieces and an induction heater with at least one induction coil. The reactor has a loading opening and a discharge opening for the treated melt. The coke bed is ring-shaped around a tube-shaped element. The material of the tube-shaped element allows inductive coupling to the induction field of the induction coil and it has draw-off openings for drawing off reaction gases from the coke bed.

摘要： Disclosed is a method of melting a metal, which can demonstrate improved heat efficiency, increased yield and minimized pollutive gas generation. In this method, a metallic material stacked in a melting furnace is melted by heating it directly with the flame from a fuel burner using an oxygen gas having a purity of 60 to 100% as a combustion assisting gas. The oxygen gas is burned at an oxygen-to-fuel ratio of 0.55 to 0.99, while the unburned portion of the combustion gas is allowed to burn by O.sub.2 supplied separately through oxygen lances. Meanwhile, the metallic material is preheated by burning the unburned portion of the combustion gas, whereas the combustion assisting gas is heated before it is fed to the burner.

摘要： A melting furnace or cupola utilizing electric arc heaters to provide an arc-heated air stream to melt loose metal chips as well as larger pieces of metal scrap. In one embodiment, the arc-heated gas stream and metal chips are directed into a melting segment with the melted chips and gas stream passing therefrom into the furnace through a tuyere. In another embodiment an electric arc heater serves as a tuyere for the furnace with the metal chips being fed into the arc-heated stream at the outlet of the arc heater. The chips and arc-heated air stream immediately enter the furnace wherein melting of the metal chips occurs. With either embodiment, recycling of the gases in the furnace and metal chip preheat can be provided.

摘要： A metal oxide reduction furnace has a shaft holding a verticle column of coke. An electric arc on the side of the lower portion of the column burns a cavity in the coke column and the arc is surrounded by the side wall and inner closed end of the cavity so that high temperatures are obtained. A stream of the metal oxide in particulated form mixed with a reducing agent is projected into the cavity to react endothermically within the cavity and lower the high temperature while reducing the oxide to its metal.

摘要： A carbothermic reduction process is described for producing alumina metal containing about 10% Al.sub.4 C.sub.3. The process heats a descending charge by radiation at a rate of heat flux of 10-100 KW/sq. inch, to form a melt surface that is spaced from an open arc between a pair of electrodes. Additional alumina beyond the stoichiometric amount is preferably introduced into the reduction zone immediately surrounding the melt surface.A large moving-bed shaft furnace is utilized. This furnace comprises hearth shoulders and preferably also comprises alumina introduction ports and a charge shaping device that cooperatively interacts with the hearth shoulders to suspend the descending charge column above a pool of melted aluminum product therebeneath, whereby the aluminum product is able to flow and/or fall into the pool with minimum passage over unreacted charge.

摘要： Apparatus for the direct reduction of iron and production of fuel gas in which a fossil fuel is gasified to produce a hot gas which is tempered with a carbon dioxide rich gas. The mixture is reacted with carbon to upgrade it in reducing potential and is desulfurized by reaction with lime in a first shaft furnace to form a hot reducing gas. The hot reducing gas is utilized as the reductant in a counterflow shaft reduction furnace, a minor portion of the spent reducing gas is recycled as tempering gas for the gas from the hot gasifier, and the major portion of spent reducing gas becomes a source of fuel gas. The apparatus includes a gasifier, counterflow shaft gas reactor, a shaft type direct reduction furnace and associated equipment.
