A system, apparatus, and method are provided for venting a direct quench casting mold during a direct quench casting process by venting excess casting gas from the top of the casting and retaining oxides. A method of exhausting casting gas from a direct chill casting mold includes: supplying molten metal to the direct chill casting mold through a transition plate; supplying a casting gas through a casting surface of the direct chilling casting mold; exhausting the casting gas from a gas pocket in the transition plate, wherein exhausting 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. 本文提供了一种用于在直接激冷铸造工艺期间通过从铸件顶部排出过量铸造气体并且保留氧化物来对直接激冷铸造模具进行排气的系统、设备和方法。从直接激冷铸造模具中排出铸造气体的方法包含：通过过渡板向所述直接激冷铸造模具供应熔融金属；通过所述直接激冷铸造模具的铸造表面供应铸造气体；从所述过渡板中的气体凹穴中排出所述铸造气体，其中从所述过渡板中的所述气体凹穴中排出所述铸造气体是响应于所述气体凹穴中的所述铸造气体的压力达到预定压力而执行的。
