Abstract
Способ выплавки стали, включающий выплавку стали сериями с подачей в дуговую электросталеплавильную печь в качестве металлошихты металлолома и жидкого чугуна, расплавление, окислительный период с использованием газообразного кислорода, выпуск плавки с оставлением шлака и части металла в печи, присадку в ковш во время выпуска твердой шлакообразующей смеси, раскислителей и легирующих, отличающийся тем, что продувку стали газообразным кислородом проводят с интенсивностью 80-120 нм/ч на тонну выплавляемой стали до содержания углерода в стали не более 0,05% ниже нижнего предела содержания его в готовой стали, а за 0,5-4 мин перед выпуском стали из печи продувку кислородом прекращают и осуществляют вдувание углеродсодержащего материала с расходом 10-80 кг/мин.A method of steel smelting, including smelting steel in series with feeding into an electric arc furnace as a charge of scrap metal and liquid iron, melting, an oxidation period using gaseous oxygen, tapping the smelt leaving the slag and part of the metal in the furnace, adding to the ladle during tapping solid slag forming mixtures, deoxidizers and alloying agents, characterized in that the blowing of steel with gaseous oxygen is carried out with an intensity of 80-120 nm / h per ton of steel smelted until the carbon content in the steel is not more than 0.05% below the lower limit of its content in the finished steel, and for 0 , 5-4 minutes before the steel is discharged from the furnace, oxygen blowing is stopped and injection of carbon-containing material is carried out at a rate of 10-80 kg / min.
