ABSTRACT:
A casting system for pouring nonferrous metal molten masses, in particular copper or copper alloys, has a tundish and a submerged pipe feeding into a molten bath inside a thin-slab mold. Trouble-free discharge of the melt into the mold and degassing at the exposed surface of the mold is ensured. The submerged pipe leading from the tundish along a pre-defined pouring angle has first and second sections. The latter is a tip nozzle that submerses into the molten bath. It has at its wall facing the mold bottom one or more discharge openings effecting a change in the flow direction of the molten mass. A lip at the tip nozzle is spaced so as to overlap the discharge opening, to cause a second flow direction change and lateral distribution. The discharge opening and the lip are disposed inside the mold bath, below a bath surface, during operation.
