Abstract

1. Способ выплавки стали в дуговой сталеплавильной печи, включающий завалку шихты, ее расплавление, проведение окислительного и восстановительного периодов плавки и выпуск металла из печи, отличающийся тем, что после оседания поверхности шихты до верхнего уровня стен уменьшают объем рабочего пространства печи путем опускания свода вместе с охлаждаемой цилиндрической подставкой и проводят последующие операции.2. Устройство для выплавки стали представляет собой водоохлаждаемый свод, имеющий патрубок газоотсоса с двумя отводами к камере дымососа и соединяемый с охлаждаемой цилиндрической подставкой при помощи замков.1. A method of smelting steel in an arc steel-making furnace, including charging a charge, melting it, carrying out oxidation and reduction periods of melting and tapping metal from the furnace, characterized in that after the surface of the charge has settled to the upper level of the walls, the volume of the working space of the furnace is reduced by lowering the roof together with a cooled cylindrical support and carry out subsequent operations. 2. The device for smelting steel is a water-cooled vault with a gas suction branch pipe with two outlets to the smoke exhauster chamber and connected to a cooled cylindrical support with locks.
