[Illustration: BENDING ARMOR PLATE
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.
