摘要： The invention relates to a method of rapidly decarburizing a high-carbon ro-alloy with oxygen for avoiding an undesirable oxidation of the principal alloying elements, especially chromium or manganese, comprising blowing an oxidizing gas under the surface of a bath of molten ferro-alloy from one or more gas-jacketed nozzles in an amount ranging between substantially 3 and 15 m.sup.3 S.T.P. per metric ton of ferro-alloy with reduction of the carbon content of the ferro-alloy at a rate of about 0.2% to 1%. Comminuted solids, especially particles of oxides of alkaline-earth metals such as powdered lime, may be admixed with the oxidizing gas to prevent the ejection of molten metal from the bath.

摘要： An improvement in the refining of molten metals in a converter by means of oxygen introduced into the metal through tuyeres which include two concentric pipes, oxygen being passed into the melt through the central pipe and a protective fluid being passed into the melt as a sheath or screen around the oxygen, through the clearance space between the two pipes. In the present invention two tuyeres, disposed horizontally and each passing through the convertor sidewall permit refining to be accomplished without any slopping or splashing of the melt and with only minor wear of the convertor lining.

摘要： A method for after combustion of reaction gases resulting from the decarburization of liquid steel in reaction vessels under vacuum includes the steps of arranging a blow-in opening within a refractory lining of a reaction vessel and introducing an air stream, comprised of hot air of a temperature between 800.degree. C. to 1400.degree. C., counter to the flow direction of the reaction gases via the blow-in opening into the reaction vessel. A device for performing after combustion of reaction gases resulting from the decarburization of liquid steel in a reaction vessel under vacuum includes a generator, connected to the reaction vessel, for producing hot air. The generator contains a bulk of balls for heating the air guided through the bulk of balls and subsequently introduced into the reaction vessel. The bulk of balls consists of a refractory material and is heated by heat energy.

摘要： The invention relates to a method for smelting reduction of metal ores involving a combination process wherein the metal ores are partly reduced in one or more stages and then completely reduced to metal in a melt-down reactor. The combination process comprises at least three process units, and the melt-down reactor forms one process unit. The partial reduction of the metal ores is performed in at least two further process units. A different waste gas is produced in each of these at least three process units.

摘要： This invention relates to a method for installing a converter bottom, using not only bottom bricks of commercial brick formats but also shaped and fitting bricks, the largest area on a bottom plate being lined with bottom bricks of commercial brick formats, leaving a space free. After the bottom has been inserted into the converter, shaped bricks are laid one beside the other in the free edge area adjacent to the converter walling, the sides of these bricks facing the converter walling being fitted to the curvature of the converter walling. These shaped bricks are of a size such that a free space exceeding one joint width remains between each shaped brick and the adjacent bottom brick. Fitting bricks true to dimensions are laid in these free spaces.
