Фо|)мула изобретени Fo |) Mula Invention

Способ получени  основной стали, заключающийс  в расплавлении шихты, раскислении металла алюминием, обработке шлакообразующими материалами и продувке газом, отличающийс  тем, что, с целью снижени  содержани  неметаллических включений и увеличени  сопротивлени  усталостным разрушени м , алюминий ввод т в ковш до снижени  содержани  кислорода в металле 0,001- 0,003% одновременно со шлакообразующими на кислой основе, а продувку газом ведут с интенсивностью 0,25-0,30 м /т-мин.The method of obtaining basic steel, which consists in melting the charge, deoxidizing metal with aluminum, treating with slag-forming materials and blowing gas, characterized in that, in order to reduce the content of non-metallic inclusions and increase resistance to fatigue damage, aluminum is introduced into the ladle before the oxygen content in the metal decreases 0.001- 0.003% simultaneously with slag-forming on an acidic basis, and purging with gas is carried out with an intensity of 0.25-0.30 m / t-min.
