Abstract
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.
