摘要： A method and apparatus for producing molten iron in which pulverized coal is gasified with oxygen in an iron melting chamber, iron pellets on an upstanding hearth in the melting chamber are exposed to the gasification heat and melted. Molten iron trickles down from the hearth to a surrounding liquid bath. Off-gases from the chamber are utilized for direct reduction of iron oxide pellets to produce hot reduced iron pellets which are melted in the chamber.

摘要： Iron-containing materials are loaded into the top of a shaft furnace to form therein an upright column of the materials. A burner forms a flame above the floor of the furnace to heat the base of the column and thereby melt the materials at the base of the column into a liquefied-iron melt on the floor of the furnace and a layer of slag on the melt. In addition this flame formed by the burner forms a deposit in the furnace on which the column is supported. Slag is continuously withdrawn from the furnace at a location substantially level with the deposit and the melt is withdrawn from the furnace at a location below the layer of slag and is heated as it is withdrawn. This melt is withdrawn through an iron-drain conduit having an outlet end vertically positioned to be horizontally even with the lower surface of the slag and a refining vessel working inductively or by means of an electric arc may be provided in this outlet conduit for the continuous transformation of the liquefied iron into steel.

摘要： A method for reducing iron oxide in a melt of iron by maintaining a reduction layer on the surface of the molten iron and passing the molten metal from the melt through vertical channels which communicate at the bottom of the metal melt an with a space at the top of the melt which is above that of the reduction layer so as to pass the melt including the oxide there through the reduction layer, the molten metal being lifted up through the channel by means of a gas lift pump action and heating the molten metal by inductive heating while it is flowing through the channel.

摘要： A cupola for melting pig iron or steel scrap. The cupola has a belly having a tapping hole at the lower portion thereof, a plurality of more than two spiral combustion chambers provided outside of belly burners. The burners use creosote oil as fuel and direct flame into these combustion chambers. The combustion chambers are provided with tuyeres for blowing flame from the burners into the belly, and the space under the belly is filled with a large number of block-shaped elements of refractory material having a high degree of refractoriness.

摘要： A method for operating a metallurgical furnace and a simplified way of providing synthesis gas for a metallurgical furnace, includes the following steps performing a combustion process outside the metallurgical furnace by combusting a carbon-containing material with an oxygen-rich gas to produce an offgas, which offgas is a CO2 containing gas; and combining the offgas, while having an elevated combustion-induced temperature due to the combustion process, with a hydrocarbon-containing fuel gas to obtain a first gas mixture having a temperature above a reforming temperature necessary for a reforming process, preferably a dry reforming process; the first gas mixture undergoing the reforming process, thereby producing a synthesis gas containing CO and H2, the reforming process being performed non-catalytically; and feeding the synthesis gas into the metallurgical furnace.

摘要： A device for determining the topography of the burden surface in a shaft furnace (10), the device comprising a radar device (20) that scans the burden surface (18) and has an antenna device (22) arranged in the area of a furnace cover (13), the antenna device being arranged on an axis of rotation (24) that is inclined in relation to a vertical axis (15) of the shaft furnace at an angle of inclination α and being rotatable about the axis of rotation by means of a drive device in such a manner that a radar fan beam (28) formed by the emitted radar radiation of the antenna device is incident upon the burden surface along a profile line p and sweeps across the burden surface as the antenna device rotates.
