I х М2 = 0,4 - 0,53,
где I - интенсивность продувки аргоном, м3/т•мин;
М - масса шлакообразующих, присаженных в ковш при выпуске из печи и внепечной обработке, кг/т.Method for the production of bearing steel, including melting, oxidation, release into the ladle, alloying and deoxidation of metal with silicon-containing materials and aluminum, melt blowing with neutral gas, characterized in that the undoxidized metal without slag is completely released into the ladle; slag basicity B = CaO / SiO 2 = 2 - 6 and content (FeO + MnO) = K = (1 - 5) wt.% to obtain the sulfur content (S) = 0.008 - 0.012%, and the ratio B / K is maintained in limits V / K = 1 - 3, after which the slag basicity is lowered to 1.0 - 1.5 and the metal is subjected to vacuum processing slag argon with stirring with an intensity of 0.001 - 0.010 m 3 / m • m determined from expression
I x M 2 = 0.4 - 0.53,
where I is the intensity of purging with argon, m 3 / t • min;
M is the mass of slag-forming, placed in the ladle when discharged from the furnace and after-furnace treatment, kg / t.
