Claims (2)

1. Способ выплавки стали в мартеновской печи, включающий завалку в печь твердой металлошихты, период ее прогрева, расплавления и доводки жидкого металла до требуемых характеристик, осуществляемой с применением продувки жидкого металла нейтральным или инертным газом через подину по зонам вдоль продольной оси с регламентированным расходом и использованием устройств по системе VVS, отличающийся тем, что до начала и/или при завалке шихты, в печи образуют ванну жидкого расплава металла с содержанием углерода более 2,3% в количестве 6-10% от массы металлошихты.1. A method of steel smelting in an open-hearth furnace, including filling a solid metal charge into a furnace, the period of its heating, melting and refinement of liquid metal to the required characteristics, carried out using liquid metal purging with neutral or inert gas through the bottom along the zones along the longitudinal axis with a regulated flow rate and using devices according to the VVS system, characterized in that prior to and / or when charging the charge, a molten metal bath is formed in the furnace with a carbon content of more than 2.3% in an amount of 6-10% by weight m metal charge. 2. Способ по п. 1, отличающийся тем, что ванну жидкого расплава металла образуют путем оставления в печи части жидкой стали от предыдущей плавки, в количестве 6-10% от массы металлошихты и последующего ее науглероживания до содержания углерода более 2,3% до начала и/или при завалке шихты. 2. The method according to p. 1, characterized in that the molten metal bath is formed by leaving in the furnace part of the molten steel from the previous heat, in the amount of 6-10% by weight of the metal charge and its subsequent carburization to a carbon content of more than 2.3% to the beginning and / or when filling the charge.
