<p>() A plurality of conveyorized molds, having nugget cavities which are deep compared to their width, are passed beneath a continuously pouring stream on non-ferrous molten metal at a rate of speed such that the cavities are only partially filled to prevent bridging over and freezing together of nuggets in consecutive cavities. Bridging over is further prevented by providing a knife edge surface between consecutive cavities wherein the stream is split between said cavities in such a manner that it is received substantially all within the mold cavities, there being little or no accumulation of metal on the surface of the mold cavities. This apparatus and method of pouring minimizes watting of the vertical wall portions of the cavities, whereby uniformly shaped nuggets are formed without attendant formation of undesirable rises, sprues or tails which cannot be easily or inexpensively removed from the nuggets.</p> |
