FIELD: ferrous metallurgy. SUBSTANCE: metal continuous casting plant includes rectangular cross section mold, intermediate ladle and immersible nozzle with inner axial duct. There are four lateral discharging ducts in walls of dead bottom of nozzle. Axes of said ducts are oriented towards inner angles of mold. Nozzle has stoppers for setting it. Ratio of total area of cross sections of lateral discharging ducts to cross section area of axial duct consists 1.1-6.0. EFFECT: lowered intensity of metal flows in cross and length sections of solidified ingot. 8 cl, 1 tbl, 16 dwg
