Abstract:

Systems and methods for cooling a heat-treated metallic part include a plurality of atomization nozzles disposed on a stage and radially disposed about the part to be cooled; and a fluid in fluid communication with the atomization nozzles. The fluid may gas, liquid, or a combination thereof, e.g., water and gas. During use, the atomization nozzles are generally configured to rapidly cool the thicker sections of the part relative to the thinner section since the thicker sections are generally slower to cool. In some embodiments, the stage can be configured to rotate about the part during cooling. Methods are also disclosed. In one embodiment, the method includes moving a plurality of outlets in a horizontal direction while the heat-treated part is stationary while directing an air and water mixture from the plurality of outlets onto the heat-treated metallic part
