Abstract
A method of casting metal comprising teeming molten metal into an ingot mould with a hot-top, the hot-top having a metal inner wall which is thin compared to the thickness of the mould wall and is surrounded by a heat insulating barrier, the resulting thermal expansion of the hot-top forming a gap between the inner wall of the hot-top and the shell of solidified metal on the ingot without external manipulation.
