摘要： A process for the production of steel from a quantity of charge material such as iron scrap, iron sponge, or other essentially metallic iron carriers, makes use of a bottom-blowing converter. Nozzles are provided in the bottom area of the converter and extend into a sump. In order to avoid an uncontrolled flow without the addition of molten pig iron, a molten bath is formed of the charge material by the provision of burners located at the bottom wall area in a lateral wall above the nozzles, finally distributed carbon and oxygen being separately blown in through the nozzles for producing additional melting. The burners may be located either slightly above the level of the molten bath or below such level and in the latter case, the burners are then operated as additional nozzles after their submersion.

摘要： Coal gas produced in an iron bath reactor during the gasification of coal is first cooled down in a first cooling step to a temperature of, preferably, 300.degree. C., and is subsequently purified at this temperature in a first electrofilter, then cooled down in a second cooling step to a temperature of, preferably 50.degree. C. and, finally, purified at this temperature in a second electrofilter.

摘要： A coal gas supply method converts a carbon carrier in a reactor into a coal gas by the addition of oxygen and feeds the coal gas to fuel consumers. To ensure a continuous fuel supply to the fuel consumers during the coal gasification process, a branch current of the coal gas produced is liquefied and stored. At the same time the oxygen stored in liquid form is drawn from a tank, evaporated and used in the reactor. If there is a breakdown in the coal gasification process, the stored quantity of coal gas is evaporated gradually and fed to the consumers. At the same time, oxygen drawn from an oxygen inlet pipe is liquefied and stored. Instead of coal gas, another fuel gas such as natural gas can also be used.

摘要： In the process for making steel from scrap, in each converter cycle following the charging of scrap, an amount of hot metal charge originating from a preceding converter cycle is charged over the scrap. The total charge is melted down through the introduction of fuel and oxygen via sub bath or submerged inlet tuyeres. The molten tap is tapped either into two storage vessels, in repetition cycles, and used as a hot metal charge during two subsequent charges, or the tap is added for subsequent processing, in production cycles, particularly for a casting operation wherein finish-refining is effected prior to the tapping.

摘要： An electric furnace has an inlet opening for introduction of starting materials in the upper region thereof. A pre-melting vessel is arranged above the furnace and has a discharge opening above and in communication with the inlet opening of the furnace. The bottom portion of the furnace is formed with a depression in which the starting material forms a body after its introduction through the inlet opening and is heat-treated so as to obtain slag and steel. The furnace is provided at its sides with a pair of mounting members each having a cam surface of part-circular configuration having a center on an axis which extends substantially horizontally and is located at the inlet opening of the furnace. A plurality of rollers engages the cam surfaces, the rollers being mounted on a support for rotation about their axes. An interchangeable sleeve-shaped element bounds the inlet opening and may be funnel-shaped and/or diverge in the downward direction, the axis extending through the narrowest region of the sleeve-shaped element. Due to this mounting of the furnace, and due to the shape of the sleeve-shaped element, the starting materials are continuously introduced through the inlet opening regardless of the tilted position of the furnace. The furnace further includes outlet openings for slag and steel which may be tapped in the tilted positions of the furnace.
