Caption: A mill operator controls the initial rolling operation at Alcoa's new aluminum foil plant at Lebanon, Pennsylvania.
Caption: First metal is tapped from a new 40,000-ton-per-year aluminum potline at Reynolds Metals Company's Longview, Washington, reduction plant. The first of three 168 new potlines scheduled for the plant under Reynolds' $325 million expansion and modernization program began in 1966, the new potline has started production several months ahead of schedule.
Caption: Aluminum ingot cast from a reverbatory furnace utilizing the Oxy-Fuel process at Alcan's Oswego Plant.
Caption: Blaw Knox tandem mill at new Goose Pond Island Plant of Revere Copper & Brass, Inc. continues reduction of an 18 or 24 inch ingot to thickness of a fraction of an inch. The aluminum is being blocked into a coil after which it will be further processed into finished coils or cut into individual sheets up to 20 feet long.
Caption: Symbolic of the new concept of "Metaullics" - the pumping of molten metal like water is this picture taken by Metal Pumping Services Division of Carborundum Co.
Caption: Unusually wide and long (over lO5'), the Boeing 747 wing skins rarely test the performance of this massive stretcher. Located at Alcoa's Davenport (Iowa) Works, this machine was installed with the future in mind since industry demands points to even longer and wider aluminum plate than the current giant 747 requires. Stretching provides flatness and aligns internal structural stresses. The alumium plate is placed between the huge jaws and lengthened as the machine slowly exerts its a-million pound pull.
Caption: Worker at Davenport, Iowa, works of Alcoa removes a scalped ingot from the bed of a horizontal scalping machine which produces a milled finish from a rough cast ingot. Ingot is then ready for rolling into plate, sheet and foil. (Photo courtesy Aluminum Company of America.)
Caption: Tapping electrolytic pot at Longview, Washington plant of Reynold's Metals Company.
Caption: Quality inspection of 12,000 lb. rolling ingot at Ravenswood, West Virginia works of Kaiser Aluminum and Chemical Corporation.
Caption: Slitting aluminum foil at Permanente, California plant of Kaiser Aluminum and Chemical Corporation.
Caption: Pouring 700-lb. ingots in the Port Henry Works of Alcoa of Australia Pty. Ltd., near Geelong, Victoria.
Caption: Archer Products, Inc., aluminum foil operation at Winston Salem, North Carolina. All rolling mills are equipped with automatic X-ray gauge control of web dimensions.
Caption: Two Sunbeam aluminum coil annealing furnaces at Dow Chemical Company Madison Division. Each furnace is designed to operate between 300°F. and 1000°F. and is capable of annealing up to 100,000 pounds of aluminum coil per load. Cooling takes place inside the furnace. A continuous roller chain practically eliminates maintenance and lubrication costs as its carries the furnace cars in and out of the furnace without the use of conventional wheels or bearings.

Caption: This 60-inch, five-stand, Blaw Knox cold rolling finishing mill can operate at mile-a-minute speeds. Sheet previously hot rolled to a thickness of one-eighth inch is precision rolled by this equipment to .008 to .016 inch in thickness. Photo shows the entry end of the mill, one of two computer-controlled cold mills at Alcoa's Warrick Operations, near Evansville, Indiana. This unit produces finished sheet 48 inches wide. The other turns out 36-inch wide close tolerance, high quality sheet for volume use.
Caption: New casting equipment designed to provide sheet ingot has gone into operation at the Longview, Washington, plant of Reynolds Metals Co. This includes a 90,000-lb. holding furnace and enlarged cast house and the vertical casting unit pictured. The new unit casts unalloyed ingot, extrusion billet and sheet ingot. The sheet ingot goes direct to Reynolds sheet plants eliminating need to recast unalloyed ingot at the plant.
