FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, particularly, to production of stainless steel at converter. Proposed method comprises introduction of foaming material in between the layer of slag formed due to oxidative refining in converter and fused metal composed by metal oxide or metal carrier, carbon and binder as granules or pellets. During foaming agent introduction, quantity of granules or pellets is adjusted in the range of 2-30 kg per ton a minute to ensure the preset height of foamed slag. Said height is maintained during the preset definite time. Added foaming agent is distributed layer-by-layer at the rate of 1-5 kg/m2/min per unit surface.
EFFECT: perfected casting power balance.
