Jominy Quench Tank
The quench tanks are used to quench the ends of Jominy bars to determine hardenability. A frame holds the bar and a jet of water impinges against the bottom of the bar. A pump recirculates the water.
The Jominy bar has a screw in the end. The loading tool is a stout flat steel strip with a U-notch that receives the shank and supports the head of the screw. The frame in the tank has an opening with a V-notch. The red-hot Jominy bar is lowered through the opening and the screw sets into the notch. A sliding door secures the screw into the notch and the loading tool is pulled out. As soon as the screw is seated, the pump is switched on.
