Provided herein is a system, apparatus, and method for venting a direct chill casting mold by venting excess casting gas and retaining oxide from atop a casting during the direct chill casting process. Methods of venting casting gas from a direct chill casting mold include: supplying the direct chill casting mold with molten metal through a transition plate; supplying a casting gas through a casting surface of the direct chill casting mold; venting the casting gas from a gas pocket in the transition plate, wherein venting the casting gas from the gas pocket in the transition plate is performed in response to a pressure of the casting gas in the gas pocket reaching a predetermined pressure.

Process control of intense stirring along a solidification front and adjustments in casting speeds during direct chill casting of 7xxx series alloys can decrease an ingot’s cracking susceptibility. Intense stirring control is used to reduce the thickness of the solidification front, promote agglomeration of hydrogen gas rejected at the solidification front, remove impurities rejected at the solidification front, and improve grain size. Intense stirring control is used to operate at faster casting speeds without risk of increasing the thickness of the solidification front. Optional reheating during casting to promote dispersoid formation is used to generate a high-strength zone of dispersoid-strengthened solidified metal in the outer periphery of the ingot, which can further decrease the ingot’s susceptibility to cracking.

A direct chill casting mold system includes a mold and at least one coolant bar. The mold defines a casting cavity having a casting axis along which a metal product moves during a casting process. The at least one coolant bar includes a plurality of nozzles, and the at least one coolant bar is configured to dispense a coolant via the plurality of nozzles onto a periphery of the metal product after the metal product has passed through the mold. In various aspects, the at least one coolant bar is movable relative to the casting axis.

Provided herein is a system, apparatus, and method for continuous casting of metal, and more particularly, to a mechanism for controlling the shape of a direct chill casting mold to dynamically control a profile of an ingot cast from the mold during the casting process. Embodiments may provide an apparatus for casting material including: first and second opposing side walls; first and second end walls extending between the first and second side walls, where the first and second opposing side walls and the first and second opposing end walls form a generally rectangular shaped mold cavity. At least one of the first and second opposing side walls may include two or more contact regions, where each of the two or more contact regions may be configured to be displaced relative to a straight line along the side wall.
