Abstract (en)
[origin: US4387761A] Molten metal is introduced in a continuous-casting system downwardly into a mold through a nozzle opening downwardly into the mold at an axis to form in the mold a body of molten metal having an upper surface carrying impurities above the mouth of the mold. The body of molten metal is rotated about the axis in the mold. The nozzle is provided generally at the level of the upper surface of the body of molten metal with radially outwardly projecting vanes that prevent the body from rotating about the axis at the upper surface, thereby preventing inclusions from being sucked into the body of molten metal.
