Mould for continuous vertical direct-chill casting of billets or blocks

摘要

An annular graphite liner 2 provides a continuation of a lower, inner metal surface of a mould and, to reduce heat conduction at the top of the mould, the upper part is spaced from the metal of the mould as by a slot 3, Figure 3, or by extension, Figure 4, of the liner. There may be an insulation or lubricant in the slot 3 and a hot top 4 with an apertured plate 6. IMAGE
