FIELD: metallurgy; making high-quality steels at treatment in steel complex treatment unit.
SUBSTANCE: proposed method includes melting liquid charge in steel-making unit, teeming it to "ladle-furnace" followed by treatment in steel complex treatment unit and teeming. After treatment in steel complex treatment unit, final treatment of steel is performed by pouring it from "ladle-furnace" into teeming ladle with covering slag formed in steel complex treatment unit. Proposed method is carried out in production line provided with off-furnace treatment unit including steel complex treatment unit, "ladles-furnaces", tapping ladles, teeming unit and final treatment unit located between steel complex treatment unit and teeming unit.
EFFECT: reduction of time required for treatment of steel in "ladle-furnace"; reduced number of "ladles-furnaces".
