摘要： In the operation of mills for the production of steel from molten pig iron and solid ferrous carriers, it is sought for economic reasons to increase the portion of solid ferrous carriers. To supply thermal carriers, such as fossile fuels, as is known, involves the disadvantages of extended charging times and of undesired accompanying elements introduced into the process.To avoid these disadvantages, the invention provides for a combination of at least one steel converter with a direct reduction plant, a meltdown gasifier and a cupola. Therein, sponge iron discharged from the direct reduction plant is melted to pig iron in the meltdown gasifier, on the one hand, and is used as solid charge for the converter. Scrap, together with coke, is melted in the cupola to blown metal, the latter, together with the pig iron produced in the meltdown gasifier, being supplied to the converter as liquid charge.

摘要： In operating a mill including a blast furnace and a steel converter, it is difficult to mutually adapt the operations of the blast furnace and of the converter in a flexible way. When using scrap as a coolant in the refining process, undesired accompanying elements are introduced into the metal melt.The invention consists in that, instead of a blast furnace, a direct reduction plant in combination with a meltdown gasifier are provided as the pig iron source. This aggregate is operated in combination with a single steel converter. The direct reduction plant, on its discharge side, is connected both with the meltdown gasifier and with the steel converter via sponge iron transporting devices. The meltdown gasifier communicates with the steel converter via a transport line for molten pig iron. As the solid charge in the refining process sponge iron is exclusively used.

摘要： With a method for producing metals, the raw material is melted in a metallurgical vessel by at least one plasma burner directed from top to bottom. In order to be able to protect the furnace brickwork from too strong a thermal load exerted by the plasma jet, and to make available the energy supplied by the plasma burner to melting and reducing the fine ore to as large an extent as possible as well as to prevent an agglomeration of the raw material to be used, the raw material is topcharged into the metallurgical vessel in the form of fine particles directed parallel to the plasma jet so as to peripherally surround the same. Oxygen-containing gases and carbon are bottom-blown into the vessel through the melt. A foamed slag is formed in the vessel, surrounding the plasma jet over its total height and the flow of supplied raw material particles peripherally. In an arrangement for carrying out the method the plasma burner is peripherally surrounded by a jacket so as to form a supply space for the fine raw material particles which surrounds the plasma burner peripherally. Nozzles are provided in the bottom of the metallurgical vessel to supply oxygen-containing gas and carbon.

摘要： A burner for the combustion of fine-grained to dusty solid fuels incorporates a central internal tube for supplying the solid fuels and an annular gap surrounding the internal tube and delimited by a cooled external tube, for supplying oxygen or oxygen-containing gas. The annular gap ends externally by an exhaust port directed obliquely relative to the longitudinal axis of the burner and peripherally surrounding the end of the central internal tube, or by a plurality of exhaust ports annularly disposed about the longitudinal axis of the burner. In order to ensure the complete combustion of the fine-grained to dusty fuels at a long service life of the burner, the inclination of the exhaust port(s) relative to the longitudinal axis of the burner is below 20.degree.. The exhaust port(s) is/are arranged transverse to the longitudinal axis of the burner and in the radial direction relative to the same at a distance of between 5 and 30 mm from the inner wall of the internal tube. The inclination of the exhaust port(s) relative to the longitudinal axis of the burner and the radial distance of the exhaust port(s) relative to the inner wall of the central internal tube are coordinated in a manner that the intersection of the extensions of the exhaust port and of the inner wall of the internal tube outside of the burner lies 20 to 80 mm in front of the burner mouth.
