Abstract
An apparatus and process are described for continuously casting molten metal. The apparatus includes (a) an open-ended direct chill casting mould comprising a mould plate having an inner axially extending wall or walls defining a mould cavity, (b) coolant delivery aperture or apertures adjacent the mould cavity adapted to discharge a stream or streams of coolant inwardly in the direction of metal movement to impinge on an ingot being formed, and (c) deflector means for deflecting the coolant stream or streams in a variable direction dependent on the local shrinkage conditions of the ingot being formed such that the coolant impinges upon the ingot at a constant distance below the mould plate around the periphery of the ingot and preferably at a constant relative impingement angle. The deflector means is preferably a movable baffle having a deflector face contoured to impart the desired deflection pattern to the coolant stream.
