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.
Rotary furnaces and processes for heat treating a workpiece generally include an external shell wall and a refractory lining abutting the shell wall to define a substantially cylindrically shaped interior chamber for treating one or more workpieces; an opening in the an external shell wall and a refractory lining for loading and unloading the workpieces; a rotatable hearth for receiving and rotating the workpieces within the substantially cylindrically shaped interior chamber; and a plurality of thermal isolation walls, wherein adjacent thermal isolation walls define a space effective to accommodate and thermally shield each one of the workpieces to be treated and have a height at least equal to a height of the workpiece. The presence of the thermal isolation walls substantially prevents heat transfer between the workpieces being treated.

A die locking device (100) including a press (102) having a top end (106), a bottom end (108) and a plurality of channels (104) disposed around a perimeter of the press (102). The device also includes a plurality of actuators (110), each of the plurality of actuators (110) affixed to a first end (112) of one of a plurality of locking arms (114) that are each at least partially disposed in one of the plurality of channels (104). The device also includes a plurality of locking clips (118), each affixed to a second end (116) of each of the plurality of locking arms (114) and each affixed to one of a plurality of hinges (120). The plurality of hinges (120) is configured to receive and secure a die stack (122) to the top end of the press (102).
A gripper assembly for a forging manipulator includes a main body (12) configured to be in operative communication with the manipulator; a contact plate (14) attached to the main body (12) and configured to be in physical communication with a heated metal part (18); and an insulating plate (16) disposed between the main body (12) and the contact plate (14), wherein the insulating plate (16) is configured to substantially prevent heat transfer from the heated metal part (18) to the main body (12).
