Claims (1)

Способ обработки стали в ковше включающий ввод алюминия в жидкий металл, продувку металла кислородом через погружную футерованную фурму с керамическим соплом для подогрева и перемешивания металла со снижением расхода кислорода при перемешивании металла, отличающийся тем, что кислород подают со скоростью истечения 200-1200 нм/с из сопла фурмы, которую погружают в металл на 80-95% высоты ковша, причем при подогреве металла и его перемешивании расход кислорода поддерживают в пределах 0,10-0,30 нм3/т•мин и 0,01-0,05 нм3/т•мин соответственно.A method of treating steel in a ladle comprising introducing aluminum into a liquid metal, purging metal with oxygen through an immersed lined lance with a ceramic nozzle for heating and stirring the metal with a decrease in oxygen consumption while stirring the metal, characterized in that oxygen is supplied at a flow rate of 200-1200 nm / s from the nozzle of the tuyere, which is immersed in metal at 80-95% of the height of the bucket, and when the metal is heated and stirred, the oxygen flow rate is maintained in the range of 0.10-0.30 nm 3 / t • min and 0.01-0.05 nm 3 / t • min, respectively.
