ALUMINUM FOIL MILL — EFFICIENT PRODUCTION OF HIGH-QUALITY, LOW-COST FOIL
The most advanced foil rolling mills in the world enable producers to achieve the highest quality foil at the lowest cost.
The increasing demand for ever higher quality and greater quantities of rolled aluminium foil has forced equipment manufacturers to adapt to new market requirements. 6 micron and below finished thicknesses are now the norm, along with rolling speeds of 2,000 m/min. Primetals Technologies has developed solutions that meet these demands; our mills are state-of-the-art, including features for high-speed operation and control, providing consistant production volumes. Our process know how and support ensures record start-up times with saleable coils produced from cold starts.
Aluminum Foil Mill — High quality, low cost production
Primetals Technologies' portfolio of Roughing, Intermediate, Finishing, Universal, and Bright Finish Foil mills is aligned with the market trend toward greater coil weights, combined with wider strip, thereby helping our customers to maximize yield and productivity. Offering a completely integrated automation and drive solution, including the latest generation of drive technology and a powerful automation platform, ensures:
- Rolling speeds of 2000 m/min
- Product widths of > 2000 mm
- Finished thickness of 0.0055 mm (5.5 microns)
Features:
- Air Bearing ShapeMeter (ABSM) roll provides highly sensitive solution for accurate flatness feedback
- Integral Solenoid Valve (ISV) sprays for improved flatness control
- Back-up roll chock cooling increases mill production through constant high-speed passes
- Edge trimming and scrap removal reduces the risk of strip breaks
- Vapor Shield fume cleaning and rolling oil recovery reduces harmful emissions
- Automated foil feed system for operator safety
- Fast work roll change sequence maximizes mill availability
- Mill bearing temperature monitoring, cooling & analysis is important with long high-speed passes
- Schneider Coolant Filtration maximises mill availability and minimizes waste
