<p>A magnetic confining apparatus for preventing the escape of molten metal through an open side of a gap between two horizontally disposed members (10a,10b), between which the molten metal is located, said apparatus comprising: first electromagnet means (20,24,28) comprising a first magnetic core means and a first electrically conductive coil means operatively associated with said first core means, said first coil means connected to an alternating current power source for generating a first, mainly vertical magnetic field extending through the open side of said gap to said molten metal to exert a confining pressure against an edge of the molten metal in the gap. <IMAGE> <IMAGE> <IMAGE></p> |
