Caption: Sheet ingots are cast by direct chill at Commonwealth Aluminum, Lewisport. Kentucky. Having a capacity of 90,000 lbs. per cast, the casters employ a tilt-type mold carriage and an internally guided singleacting hydraulic main cylinder of 21" bore. Each casting machine is powered by a 50 hp hydraulic drive. The casting stations were built by Loma Machine, a Hill Acme Company.
Caption: An operator checks a monitor displaying thickness of aluminum strip on a light-gauge slitting line at the new Logan Aluminum plant at Russellville, Kentucky. Accuracy of strip thickness is held to within ±0.1 percent with the use of AccuRay 7000 Micro measuring system.
Caption: This 50,000-ton forging press at Wyman-Gordon Company's Worcester, Massachusetts, plant produces large airframe components from aluminum and titanium. Put in operation in 1955, it is one of the largest in the world and was a part of the Air Force's heavy press program. It was purchased by Wyman-Gordon in 1982. See story on filtration of ingot poured for the press.

Caption: Molten aluminum is poured from a ladle in the casthouse of the Aluminerie de Becancour Inc. smelter.
Caption: An aluminum-lithium ingot emerges from the mold in the new Loma-Mann semi-continuous casting plant at the Kitts Green Works of Alcan Plate Limited, West Midlands, U.K. The equipment employs PLC control of all functions, integrated to liquid metal supply, allowing the casting operation to be undertaken with operating personnel divorced from the casting environment. Wellman Furnaces Ltd. of West Midlands undertook complete design, in conjunction with Alcan engineers, including programming of the control functions linked to the Alcan patented pulsed water feed system. The plant can cast up to 25 metric tons at once with an ingot length of 5500mm (18 feet). Casting speed is 300mm (11.8 inches) per minute with an accuracy of +/- 0.5%. Controls automatically start and stop the machine.
Caption: The role of Reynolds Metals Company's technology in transportation applications is demonstrated in its production of aluminum plate used in the space program.
Caption: The 80" continuous hot mill's six high configuration permits superior flatness and crown control say Kaiser Trentwood engineers.
Caption: In this photo from the Aluminum Extruders Council's Solid Die Correction Program, a basic correction technique for relieving bearings is illustrated. The first of a three-part program is described in this issue.
Caption: Eighty-four inch wide Reynolds-designed rolling mill at Reynolds Metals Company's Richmond Foil Plant, Richmond, Virginia, is capable of 7500 fpm rolling speeds. The plant manufactures household aluminum foil, food service foil, and flexible packaging materials.
Caption: Clad in protective suits, Intalco employees pour molten iron to attach a steel bar to the anthracite cathode block which forms the bottom of the electrolytic cell.
Caption: Rebuilt at less than its original cost, this 15-year-old cold rolling mill at Reynolds Metals Company's Listerhill, Alabama, plant incorporates the most sophisticated gauge and shape controls available. Improvements have upgraded quality and productivity.
