Direct chill casting mould.

摘要

A direct chill casting device is described comprising: (a) an axially upright, open-ended direct chill casting mould plate (10) having an inner axially extending wall or walls defining a mould cavity (11), an upper annular surface (12) and a lower annular surface (13), the mould plate (10) having a generally rectangular or square cross-section at points about the axis thereof with the horizontal dimensions of the cross-section being greater than the vertical height, (b) at least one coolant channel (15) formed within the mould (10) generally parallel to and laterally spaced from the cavity-defining walls, (c) coolant dispersal discharge passages (16) extending downwardly and outwardly between said coolant channel (15) and the lower surface of the mould plate (13) adjacent the mould cavity (11), and (d) a coolant manifold (18) mounted on the lower surface of the mould plate beneath the coolant channel (15) or channels and adapted to supply coolant fluid to the coolant channel (15) or channels.
