Caption: Designed and built by L. W. Nash Company, this Alcoa casting system at their Warrick, Indiana plant is 15 per cent more efficient than earlier installations. It increases the plant's total ingot production by 25 per cent. In the process, molten aluminum is cast continuously and sawed into 30-ft.-long, 15-ton ingots for rolling into light gauge sheet.
Caption: 58" Hunter continuous sheet caster of tilt-up design, built for a South American sheet producer and put into operation this year. It produces and coils 1/4 to 1/2 inch material.
Caption: At Alcoa, Davenport, Iowa, Elwell-Parker electric platform trucks move table loads of flat aluminum sheet or plates, haul trailer loads of aluminum, and carry aluminum coils. Truck maintenance and repair costs are carefully recorded to determine the downtime costs and uptime efficiency of all trucks at Alcoa.
