The new slitting line is processing coiled aluminium strip, 900-2,150 mm wide and between 0.10-1.0 mm thick, weighing up to 31 tons.
It performs up to 40 slits, with minimum widths of 30 mm, at cutting speeds up to 800 m/min, primarily for alloys of series 1xxx, 3xxx, 5xxx, and 8xxx.
Danieli supplied the entire system, including coil entry side equipment, exchangeable slitting shears, scrap handling system, braking unit, drum shear and recoiling section, as well as the auxiliary systems.
The line operates through Danieli Automation control system and electric devices.
Special features, such as quickly interchangeable slitting shear with automatic adjustment of knife immersion and a vacuum roll braking system are included in the package, and provide optimal handling with reduced downtimes and smooth material processing.
With an annual capacity of 1,000,000 tpy, Henan Zhongfu Aluminum is one of China's most important aluminium producers.
A high-speed trimming line with a designed production capacity of some 245,000 tpy also was commissioned recently for the same customer.
