  • Patent number: 6554055
    Abstract: An apparatus for the horizontal continuous casting of profiles includes a receptacle for molten metal and an ingot mold connectable to the receptacle by a ramming frame. The ingot mold forms a casting gap having a refractory lining that cannot be wetted by the molten metal. An oscillation drive oscillates the ingot mold in a casting direction and is supported on the receptacle and on the ingot mold. A sliding guide associated with the receptacle and extending in the casting direction supports the ingot mold, and a web is arranged in a transition area between the receptacle and the ingot mold, the web being prestressed with a minimum pressure corresponding to the hydraulic pressure of the molten metal and consisting of refractory fibers that cannot be wetted by the molten metal, to provide a seal against the molten metal.
