    • A quench system includes an enclosure defining a quench chamber sized to receive hot castings, and bulk air fans in fluid communication with the quench chamber and configured to establish a bulk flow of cooling air that surrounds and extracts heat from the hot castings at a first cooling rate. The quench system also includes a pressurized cooling system in fluid communication with a plurality of nozzles within the quench chamber and configured to spray a plurality of a directed flows of cooling fluid onto the hot castings to extract heat at a second cooling rate. The quench system further includes a programmable controller configured to sequentially activate the bulk air fans to cool the casting at the first cooling rate for a first predetermined period of time, and then activate the pressurized cooling system to cool the casting at the second cooling rate for a second predetermined period of time.
    • 骤冷系统包括限定了用于接收热铸件的骤冷室的外壳和与骤冷室流体连通的大体积风扇,并且被配置成在第一冷却下建立围绕并从热铸件中提取热量的大量冷却空气流 率。 骤冷系统还包括与淬火室内的多个喷嘴流体连通的加压冷却系统,并且构造成将多个指向的冷却流体流喷射到热铸件上以第二冷却速率提取热量。 骤冷系统还包括可编程控制器,该可编程控制器被配置为依次启动大量风扇以第一冷却速率冷却第一预定时间段的铸件,然后激活加压冷却系统以第二冷却速率冷却铸件 第二预定时间段。
