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： An arrangement for cleaning a lance head of a lance introducible into a metallurgical vessel includes a cleaning head being in contact with the lance head during the cleaning procedure and surrounding the lance head. The cleaning head and the lance are relatively movable in the direction of the axis of the lance. In order to be able to carefully clean the lance head on its side facing the melt bath present in the metallurgical vessel by preventing the penetration of slag during the measuring procedure between the measuring and/or sampling probe and the end face of the lance, the cleaning head and the lance are placeable into an aligned position by an adjustment device. The cleaning head is settable into a rotational movement reciprocating about the axis of the lance by an oscillation device.

摘要： In a method of producing a mixed gas from a process gas of a continuously working gasifier and a discontinuously incurred off-gas of an oxygen blowing converter, the off-gas of the refining process having the lower pressure is sucked into the process gas of the gasifier with the higher pressure via a gas jet ejector. The process gas serves as power gas, and subsequently the mixed gas is dedusted. A plant for producing steel includes a plant for recovering pig iron formed by a reduction shaft furnace and a melt-down gasifier, and at least one oxygen blowing converter for converting the pig iron into steel. The reduction shaft furnace has a process or top gas duct system, the converter has a converter off-gas duct, and an ejector connects both, the converter off-gas thus being feedable into the top gas duct system to form the mixed gas. Common dedusting and washing devices are provided for the mixed gas and safety devices for preventing oxygen from entering into the mixed gas.
