Two 20-high, copper cold-finishing mills ordered from Danieli

To be installed in Ningbo, Zhejiang Province, eastern China, the new 20-high cold finishing mills for Ningbo Powerway Alloy Material Co. will competitively roll a wide product mix of copper alloys, from soft pure copper up to hard phosphor bronze. Strip dimensions will range from an entry thickness of 1.2 mm down to a minimum finish thickness of 0.03 mm, at a maximum strip width of 650 mm.

Manufacturing the core equipment in Meinerzhagen at Danieli Germany workshops and based on Danieli Fröhling technology, the twin-housing type mills will be equipped with the patented intermediate-roll double bending system for improved strip flatness and direct hydraulic roll-gap control for high-precision thickness performance. The mills will be capable of using a large range of work-roll diameters, from 37 to 80 mm, in order to achieve efficient and economic rolling performance.

The final applications of the high-performance copper-alloy strip produced by Ningbo Powerway Alloy Material Co. will be mainly used for aerospace, high-speed trains, solar energy, telecommunication and electronic industry.

Plant startup is expected by the last quarter of 2020.
