Caption: A second reel and belt wrapper have been added to the two-high Achenbach reversing hot mill at the Joliet plant of Alumax Mill Products Inc. The addition of this second reel, which was manufactured by Mesta and powered by a 900 horsepower Reliance DC drive, enables the Joliet plant to produce larger diameter coils with improved finish and closer gauge control at higher production rates. The new mill configuration is the only one of its type in the U.S.
Caption: Siphoning molten aluminum into ladle from potline at Alcan Aluminum's Arvida, Quebec smelter. This is the world's largest aluminum smelter.
Caption: Loewy Robertson non-reversing 4-high cold mill for aluminum strip 455 mm and 1270 mm x 1830 mm at Ranshofen, Austria.
Caption: Molten ferrosilicon used in the manufacture of magnesium at Northwest Alloys in Addy, Washington. International Magnesium Association members visited the plant last month.
Caption: An overall view of the No. 5 cold aluminum strip mill at Sidal Aluminum in Belgium. This high technology mill has hydraulic automatic gauge control for consistent coil quality, and also has the latest Lowey-Robertson VIDIPLAN System of strip shape control. Since the installation of this computer shape control system, production of the No. 5 mill has increased by 25%, and much of the output can now be sold direct to the customer without tension levelling. Located at Sidal's Duffel plant, the mill is 510 and 1350 x 1830 mm, and rolls 10 ton coils at speeds up to 1300 m/min.
