After being rough-forged to size and re-heated, the plate is sent to the bending press to be straightened or bent to shape. The one shown is a nickel steel side armor plate, 14 inches thick. The press exerts a hydraulic thrust of 7,000 tons, with two independently operated plungers, and is served by direct-fired furnaces with movable car bottoms and two seventy-five ton hydraulic cranes.
