Caption: JUNKER indirect gas-fired pit furnace for heating 300 tonnes rolling slabs (max. 4500 mm long, upto 600 mm thick) at British Alcan Sheet Ltd., Newport Gwent, Great Britain. 30 slabs i.e., 300tonnes are heated in 6.5 hours to 590°C.
Caption: Titanium ingot inspected prior to forging at Intemational Light Metals plant at Torrance, California.
Caption: The world's largest magnesium ingot. On March 16, 1990, Norsk Hydro Canada produced the world's largest magnesium ingot at its Becancour plant. The T-bar ingot was DC cast using Norsk Hydro's exclusive state-of-the-art multi-strand technology, and weighed close to 4,500 kg. The Becancour plant produces magnesium in billets, T-bars, ingots, and grinding slabs.
Caption: The cover photograph shows finished can sheet coils awaiting packaging and shipping from one of Alumax Mill Products Inc., six plants. Their plants are located in Texarkana, Texas, Lancaster, Pennsylvania, Riverside, California and Joiliet, Illlinois.

Bottom row: Holton Castex, Extruder at Alform Alloys, SMS Hassenclever, 35 MN indirect press at Alusuisseand Holton Conform, Extruder at NKT.
Caption: New, Japanese billet caster near Toyama, illustrates industry trend toward larger capacity DC casting stations. Toyama Alloys Limited's new billet caster casts 108 strands of 6" diameter billet The facility was successfully commissioned on October 17, 1989, and has an operating capacity of 120,000 MT per annum. The casting machine shown was built by the Misawa-Van Company (Tokyo, Japan), and is equipped with the AirSlip billet casting technology supplied by Wagstaff Engineering, Inc., (Spokane, Washington, USA).

Caption: Hoisted aloft by a crane operator at Warrick Operations, this 14-ton aluminum ingot will be rolled into thin sheet. Produced in an electromagnetic caster (EMC) which uses a powerful magnetic field to confine the molten metal until it cools, this new technology provides a smoother ingot surface which requires little or no scalping.
