New, high-speed edge-trimming line for aluminium in full production at Henan Zhongfu
Supplied by Danieli Fröhling and installed at the Gongyi plant, Henan province, the new line runs at 1500 m/min
The high-speed trimming line supplied to Henan Zhongfu is in full production, processing 250,000 metric tons per year of aluminium strip. The strip thickness of the main product is 0.1-0.8 mm, with widths in the range of 900-2.150 mm, for a maximum coil weight of 30 tons. The line’s maximum strip-cutting speed is 1,500 m/min, producing primarily alloys of series 1xx.x, 3xx.x, 5xx.x, and 8xx.x.
Danieli supplied mechanical and process technologies for the entire system, including coil entry side, in-line coil preparation, electrostatic oiling, side trimming, scrap suction and high-speed recoiling, as well as the auxiliary systems and electrics/automation.
