ABSTRACT:
In continuous casting of metal in an open-ended mold through which the metal is advanced in a first direction while undergoing peripheral solidification, and to which molten metal is supplied by a shroud that opens beneath the metal level, the provision of electromagnetically produced metal circulation in the mold causing laminar flow of molten metal, in a second direction opposite to the first direction and at a rate not above 35 cm./sec., along the solid-liquid interface within the mold for preventing entrapment of inclusions at the interface.
