Claims (1)

Способ выплавки стали, в том числе высоколегированной, в кислородном конвертере с верхней продувкой, включающий завалку стального лома, заливку жидкого чугуна, продувку кислородом, введение дополнительного количества тепла, и выпуск металла, отличающийся тем, что в случае завалки стального лома в количестве более 25% от массы металлической шихты в конвертер одновременно с продувкой вводят комплект топливно-кислородных горелок, закрепленных на конце вертикально перемещаемой вдоль оси конвертера штанги, так, что они образуют веерообразно расходящиеся топливно-кислородные струи, а при выплавке высоколегированных сталей после окончания продувки при заданном содержании углерода в конвертер загружают порциями твердые легирующие материалы и расплавляют каждую порцию потоками топливно-кислородных струй, исходящих из опускаемого в конвертер того же комплекта горелок, с получением в конце расплавления всех порций заданного химического состава и температуры металла.Method of steel smelting, including high alloy, in an oxygen converter with top blowing, including filling steel scrap, pouring molten iron, blowing with oxygen, introducing additional heat, and the release of metal, characterized in that in the case of filling steel scrap in an amount of more than 25 % of the mass of the metal charge in the converter simultaneously with the purge is introduced a set of fuel-oxygen burners mounted on the end of a rod vertically moved along the axis of the converter, so that they form a fan-shaped diverging fuel-oxygen jets, and when high alloy steels are smelted after purging at a given carbon content, solid alloying materials are loaded into the converter in portions and each portion is melted by fuel-oxygen jet streams coming from the same set of burners lowered into the converter, with the end of melting all servings of a given chemical composition and metal temperature.
