Northern Copper Industry Co Ltd has selected ABB to supply and install a complete electrical and automation system for its new cold rolling mill, which is scheduled for start-up in 2021. Based on ABB Ability System 800xA distributed control system with high-performance AC 800PEC master controller, the package integrates ABB Metals RollxA Optimize cold rolling control solution and ABB's Collaborative Production Management for Metals system for the copper production process. On completion, the mill will become a first-class high-performance rolled copper strip and foil production line with an annual output of 50,000 tons. As new-type material produced with state-of-the-art technology the products will be widely used in aerospace, 5G communications, new energy industries, smart manufacturing and other high-tech application fields.
ABB’s Roll xA Optimize solution incorporates alloy measurement and advanced thickness control functions, ensuring rolled products, including a hard alloy-bronze that contains tin elements, fulfill stringent requirements. It also ensures strict synchronization between the roller surface and the copper strip foil to eliminate surface scratches caused by non-synchronized rotating of deflection rollers, and enables the customer to meet specific surface quality requirements. This is achieved through a range of proprietary drive control functions including static friction compensation, online controller parameter adaptation, dynamic compensation for acceleration and deceleration for deflection rollers.
ABB’s latest drive system model ACS880, AXR engineering high-pressure cast-iron motor, AMI high voltage modular motor, ABB’s dedicated instrumentation Millmate Tensiometer System, and measuring instrumentation and sensors will also be installed.
The quality of cold rolled flat products is a decisive factor for the metals industry. The ABB process and power system, designed for cold rolling mills, offers advanced solutions for quality supervision and analysis to meet the needs of cold rolling steel in terms of thickness tolerances, flatness and surface characteristics.
