Abstract
The apparatus has a starter bar of novel design which avoids the problems of deformation of the billet base, loss and waste of casting metal and loss of billet stability. The apparatus includes a tub-like having a peripheral wall and a central raised element or cone having tapered outer surfaces, to stabilize the base of the billet during casting and to dislodge the cooled billet as it shrinks.
