Bright Annealing Lines

Tenova Bright Annealing lines are designed with the following technologies:

• high efficiency cleaning section (double stage) with high efficiency brushes (conventional or brush to brush) and circulation system
• Brush consumption optimization (BCO) to have more uniform brush consumption
• alkaline solution filtration or ultrafiltration system (optional)
• waste water continuous filtration with resins bed plant (optional)
• improved looper with reduced inertia and friction
• accurate tension control through a dedicated Bridle and tension-meters design and control
• possibility to install a in line skin pass mill

Annealing is performed in a muffle furnace ( or alternative in electrical furnace) having controlled inert gas atmosphere without oxygen. Dew Point  has to be at the lowest value so to have great brightness on the outgoing strip

The line is made by the following equipment:
 

• Double unwinding section with pay off reels and paper winders
• Threading section with peelers, pinch rolls, flatteners, conveyors and shears
• Welding section with centering devices
• Degreasing, rinsing and drying section
• Entry storage section with vertical accumulator, steering and bridle rolls
• Annealing section with vertical electrical furnace and jet cooling
• Exit storage with vertical accumulator, steering and bridle rolls
• Optional tension leveler / skin pass mill with auxiliary looper
• Exit Section with inspection station, exit shear, tension reel
• Paper unwinder
