Embodiment Construction
[0133] In the following description of the preferred embodiments of the present invention, like and like reference numerals designate the same or comparable components.
[0134] Referring now to these drawings in detail Figures 1 to 6 , and first refer to its figure 1 , is shown here as an example of a possible embodiment of a power generating mechanism using the thermal energy contained in the thermal process exhaust gas (roof) 20 of an electric arc furnace 10 of a steel production plant, which power generating mechanism is used in A shredding system 40 attached to the electric arc furnace (EAF) 10 is operated.
[0135] For this, at least one recuperator boiler 30 is installed in the exhaust gas system 21 of the dedusting plant 24 of the electric arc furnace 10 . The recuperative boiler 30 can in particular be located at the outlet of a settling tank 22 used in the exhaust gas 20 and / or in the area 23 of the exhaust gas system 21 or in the preceding equipment 22 / Dust pa...

The invention relates to a steel production plant (1) and a method for uninterrupted or at least cyclical steelmaking in the plant (1), wherein in the case of uninterrupted steelmaking at least the first three of the following steps are used , and in the case of cyclical steelmaking, all five of the following steps will be used: - the charge material is melted in an electric arc furnace (10) without interruption or at least cyclically; and / or loading material of shredded scrap iron pieces (71), reduced iron (DRI) and / or hot briquetted iron (HBI) in a shredding system (40) for steel scrap (scrap 70), uninterrupted Feed the electric arc furnace (10) continuously or at least continuously during a melting process cycle by conveying mechanism (50, 51, . . . ); Discontinuously or reciprocatingly discharged; - the electric energy is uninterrupted or at least less than one Produced during the melting process cycle; - a shredding system (40) assigned to the electric arc furnace (10) for shredding scrap iron and / or steel scrap (scrap 70) for exhaust from the process (furnace top 20 ) generated electricity is supplied continuously or at least during one melting process cycle. Benxi Steel production plants (1) consistently continue this trend of recent years, which sets new standards in terms of overall energy balance versus productivity and energy savings.
Description
technical field [0001] The present invention relates to a steel production plant and a method for uninterrupted or at least cyclical steelmaking in the plant, the plant comprising at least one electric arc furnace (EAF) for uninterrupted or at least cyclical melting of charge materials, Especially like shredded scrap iron. Background technique [0002] In one aspect, steel can be made from iron ore and pig iron via the blast furnace and reformer routes. However, with respect to energy efficiency, it is on the other hand more advantageous to produce steel mainly by melting in the electric arc furnace scrap iron scrap, which is still the most commonly used charging material for electric arc furnaces throughout the world . [0003] Steelmaking in the Electric Arc Furnace (EAF): [0004] In the common electric arc furnace process, electrical and chemical energy is used to repeatedly melt the charge material. During this process, a significant portion of the total energy is c...
