<p>A device is described for collecting molte metal break- outs which may occur during direct chill casting of light metal, e.g. aluminum or aluminum alloy ingc s. The device includes a water-cooled mould (12) of the c oss sectional shape of the ingot desired, this mould having a a vertically moveable base portion (15) to support the ngformed and being disposed above a pit (10) for receiving he resultant casting and means for applying water ont the freshly solidified surface of the ingot as it emerges fromthe mould downwardly into the pit. The novel feature consists of at least one hollow container (21) adjacent the sice or sides of the ingot being formed, each container being backed with dry, highly heat-absorptive, finely divided aterial (23) having a large surface to volume ratio. Each cor ainer has an open top positioned a short distance below the nould such as to catch a break-out of molten metal at the exit of the mould.</p> |
