FIELD: treatment of molten metal in limited zone formed by bell immersed in metal. SUBSTANCE: proposed method includes immersion of lower edge of bell in melt and rotating it at speed required for coating it with lining during treatment. Rotational speed of bell ranges from 0.5 to 2 rpm. To obtain required homogeneity of molten metal, inert or reducing gas is fed for forming turbulence on surface of molten metal. EFFECT: reduced wear of bell. 5 cl, 3 dwg
