Abstract
The upper surface of an interconnecting wear device 3 is positioned in contact with the lower surface of a sand mold 1, and is centered under a molten metal feed shaft 12 which opens into the bottom of the mold. The bottom surface of the wear device rests on the upper surface of a vertically upstanding casting nose 4. The wear device comprises a hollow steel collar 7 surrounding a compressed concrete annulus 18, in turn surrounding a refractory clay sleeve 8, and is easily replaced when leakage develops due to thermal shocks, etc.
