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 и в случае добавки в конвертер после окончания продувки металла кислородом порций твердых легирующих добавок, в конвертер вводят вертикально направленный на ванну металла лазерный луч, причем в первом случае это делают одновременно с продувкой кислородом, а во втором - после ввода каждой порции твердых легирующих добавок, расплавляя их.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 and in the case of additives in the converter after the metal is flushed with oxygen portions of solid alloying additives, a laser beam is introduced vertically directed to the metal bath into the converter, and in step In the first case, this is done simultaneously with oxygen purging, and in the second, after the introduction of each portion of solid alloying additives, melting them.
