The new line will process automotive and aircraft aluminium alloys, family series 2XXX, 5XXX, 6XXX and 7XXX, with a strip width range from 1.000 mm up to 2.650 and thickness range from 0.3 up to 4.5 mm. The envisaged total production for the line is about 100 000 tpy with a process speed of 60 m/min.

The line is equipped with a double unwinding pay off reels and with a tailor-made stitcher with automatic spray lubrication system. The entry side trimmer is equipped with integrated scrap chopper. The alkali degreasing section is made by a spray tunnel with multistage cascade rinsing section. Entry and exit loopers are horizontal type with double winch motorisation.

Chemical process starts with an acid tunnel etching section, followed by a no-rinse spray titanium zirconium passivation and a squeegee roll coater for oxylane product for automotive adhesive bonding application.

The exit side includes a tension leveler, a pre-aging furnace, an automatic surface inspection system, a dry lube smelter and a rotary shear. The thermal portion is supplied by EBNER Industrieofenbau GmbH, one of the leading suppliers in floating furnaces for aluminium heat treatment processing line plant, consolidating the partnership between the two companies in aluminium lines and increasing their top record reference list worldwide.

The line is expected to start its production at the beginning of 2021. “This new order confirms Tenova as a reliable partner in processing lines for aluminium thanks to our continuous effort to improve the design and the manufacture of its supply to maximise line availability”, said Nicola Cavero, Tenova senior vice president Italimpianti & Strip Processing.
