摘要： A plant for producing raw iron and/or sponge iron has a direct-reduction shaft furnace (1) for lump iron ore, a melt gasifier (3), a conduit connecting the melt gasifier (3) to the shaft furnace (1) for a reducing gas, a supply conduit (13) connecting the shaft furnace (1) to the melt gasifier (3) for the reduction product in said furnace (1), a top gas line (14) leading out of the shaft furnace (1) with lines (5, 6, 7) opening into the melt gasifier (3) for oxygen-containing gas and carbon vehicles and a run-off (11) on the melt vessel (3) for raw iron and slag. To make it possible to process not only lump but also fine ore economically over a wide range of quantities, the plant has at least one fluidised bed reactor (15, 16) to accept fine ore, a reducing gas inlet (21) thereinto, an exhaust gas outlet (22) from the fluidised bed reactor (15) and an extractor (34) for the reduction product formed in said fluidised bed reactor (15, 16), in which the top gas outlet (14) of the shaft furnace (1) and the exhaust gas outlet (22) of the fluidised bed reactor (15) open into a cleaning device (23) and then into a heater (25, 26) from which leaves the reducing gas inlet line (21) of the fluidised bed reactor (15, 16).

摘要： The proposed flush siphon comprises a housing (1) with an inlet opening (3) and an outflow opening (4); and an L-shaped immersion pipe (7) which can be fitted in the housing (1). An approximately horizontal inlet pipe section (8) of the immersion pipe (7) discharges into an approximately vertical immersion pipe section (9) of the immersion pipe (7) from the inlet opening on a side wall of the housing (1); the inlet pipe section (8) can be connected as a duct by a sealed joint to a drainage pipe (15) such as a sink unit drainage pipe; and the outflow opening (4) of the housing (1) discharges into an outflow channel. To facilitate particularly simple cleaning of the concealed siphon and ensure ease of access to the outflow channel, the immersion pipe section (9) of the immersion pipe (7) is formed as an integral part of a rising pipe section (10) in the manner of communicating vessels to create a siphon.

摘要： In a roll stand with two rolls (1, 2) forming a gap (34), the rolls can be driven via drive shafts (11, 12) by their own drive motors (13, 14), in which a toothed coupling (17) is used in combination with an articulated linkage (24) permitting a larger angular staggering of the shafts. In order to transmit maximum torques from the drive motors to the rolls (1, 2), each drive shaft (11, 12) consists of two components inclinable towards each other and at least one of the drive shafts (12), which is in two parts, has a single toothed coupling (17) to connect with one roll (2) and articulated linkages (24), especially universal joints, at the other two link positions between its components (20, 23) and towards the drive motor (14).

摘要： Described is a method of producing molten crude iron or molten crude steel from particulate material containing iron oxide using a fluidized bed, the iron oxide-containing material being first reduced in at least one preliminary-reduction stage (7) by a reducing gas and subsequently reduced to iron sponge in a final-reduction stage (8). The iron sponge is melted in a smelting gasification zone (11) into which carbon carriers and oxygen-containing gas is fed and a reducing gas containing CO and H2 is produced which is used in the final-reduction stage (8) where it reacts, is drawn off, and is subsequently used in the preliminary-reduction stage (7) where it reacts, is drawn off, is scrubbed and is finally discharged as export gas, at least part of the reacted reducing gas being freed of CO2, heated and used as recycled reducing gas for the reduction of the iron oxide-containing material. In order to ensure that the reduction proceeds without the fluidized bed 'sticking', by minimizing the amounts of hydrocarbon carriers used, part of the reducing gas flowing from the final reduction (8) to the preliminary reduction (7) is split off, scrubbed, the CO2 removed and the gas heated and subsequently used again in the final-reduction stage (8).

摘要： In a process for producing liquid raw iron or steel basic products and iron sponge from charges consisting of iron ore and possible additives, the charges are directly reduced to iron sponge in a fixed-bed reducing region (12), the iron sponge is melted in a melt gasification region (8) with the addition of carbon vehicles and oxygen-containing gas and a reduction gas containing CO and H2 is produced which is taken into the reducing region (12), reacted there and drawn off as the export gas, CO2 is extracted from the export gas drawn off and taken as an at least largely CO2-free reducing gas together with some of the reducing gas formed in the melt gasification region (8) to a further reducing region (21) for the direct reduction of iron ore. In order to reduce the investment costs of a plant for implementing this process and improve productivity, part of the reducing gas generated in the melt gasification region (8) is diverted and taken to the further reduction region (21), by-passing the CO2 elimination stage.

摘要： In a process for producing liquid pig iron (12) or semi-finished steel products from finely divided iron-containing material, especially reduced iron sponge, the iron-containing material is melted in a melting gasifying region (6) of a melt gasifier (5) with the addition of carbon-containing material and oxygen-containing gas with the simultaneous formation of a reducing gas in a bed (16) consisting of solid carbon carriers. To prevent the separation of the fine particles of the iron-containing material loaded into the melt gasifier, the iron-containing material is inserted into the melt gasifier (5) by means of an oxygen burner (15) forming a high-temperature burning region (21) centrally just above the bed (16), but in its immediate vicinity.
