摘要： A method for the direct reduction of feedstock, containing metal-oxide, to form metallic material, by contact with hot reduction gas in a reduction assembly (1): the product of the direct reduction process is discharged from the reduction assembly by a product discharge apparatus, which is flushed with seal gas, drawn off from the vent gas and subsequently dedusted. At least one portion of the dedusted vent gas is used as a combustion energy source during the production of the reduction gas, and/or as a component of a furnace fuel gas during a combustion process for heating the reduction gas, and/or as a component of the reduction gas. Apparatus for carrying out the method is disclosed.

摘要： A process for producing molten pig iron or molten steel pre-products from charging substances formed of iron ores and fluxes and at least partially comprising fines, wherein the charging substances are directly reduced to sponge iron in at least one reduction zone by the fluidized layer process, the sponge iron is melted in a melting-gasifying zone under supply of carbon carriers and oxygen-containing gas, and a CO and H.sub.2 -containing reducing gas is produced, which is injected into the reduction zone, is reacted there, is withdrawn as an export gas and is supplied to a consumer, is to be improved with a view to rendering feasible the use of fine ore in an economic manner. This is effected in thatprimarily hematite and/or magnetite fine ores and/or ore dusts are subjected to preheating by the fluidized layer process in a preheating zone,the thus preheated charging substances are completely reduced to a major extent in at least one consecutively arranged reduction zone,whereupon at least the more finely particulate charging substances are charged into the fluidized bed and/or, if desired, also into the fixed bed, of the melting-gasifying zone by forced conveyance, preferably by pneumatic conveyance, and are melted there.

摘要： Apparatus for discharging solids from a shaft furnace comprises a lock chamber structure, the interior of which is connected to the shaft furnace by a conveyor duct, and a rotor, which is rotatably mounted in the interior of the lock chamber structure and adapted to be driven and arranged to receive solids from the furnace and seals the inlet of the lock chamber from the outlet of the lock chamber. To permit a continuous discharge of solids from the furnace without an escape of gas from the furnace, the rotor consists of a cellular wheel, which has cell-defining walls in a star-shaped configuration. The conveyor duct is connected to a source of a compressed blocking gas. An exhaust gas duct communicates with the interior of the lock chamber structure adjacent to the conveying portion of the cellular wheel between the inlet and the outlet of the cellular wheel.

摘要： Apparatus for tapping a wall of a metallurgical vessel wherein a drilling machine is carried by a mounting means for reversible displacement therealong on a track. The mounting means is suspended from a laterally extending boom which swings on a stationary support, and the boom is swung by a mechanism for selectively displacing the mounting means with its drill into an operative position for drilling a tap hole in a metallurgical vessel and an inoperative position. In one embodiment of the invention, the mounting means together with its guide track for carrying the drilling machine is pivotally connected to the boom and guide means are provided to guide the pivotal swinging of the mounting means relative to the boom to guide the mounting means over a predetermined path of movement when the boom is swinging. In a further embodiment, the boom is driven to swing in opposite directions with different motors respectively thereby permitting the boom to displace the mounting means to the inoperative position at a much more rapid rate than is desired for positioning the mounting means in the operative position. In yet a further embodiment, the mounting means together with its drilling machine is guided into and maintained in the proper operative position for tapping the vessel by an alignment strut which extends from the mounting means, the end of which is contactable with a stop which is prepositioned on the vessel to be tapped. Upon positioning in the operative position, the strut is continually driven into contact engagement with the stop without the requirement of additional mechanical locking mechanisms to maintain the drill in its proper prealigned operative position.
