ABB To Supply Complete Electrical And Automation System For China’s Northern Copper Industry

Northern Copper Industry Co., Ltd (NCI) – part of the largest producer of raw material copper stock in North China – 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 (DCS) with high-performance AC 800PEC master controller, the package integrates ABB Metals Roll@xA Optimize cold rolling control solution and ABB’s Collaborative Production Management for Metals (CPM4Metals) 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 synchronisation between the roller surface and the copper strip foil to eliminate surface scratches caused by non-synchronised 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.

“The 20-high finishing mill project is part of an important strategic vision of Northern Copper Industry to build a century-long copper enterprise,” said Zhenhua Zhang, ABB Metals Lead, North Asia and China.  “We will provide ABB Metals well-proven expertise to ensure the new mill meets expectations for producing high-precision and high-quality copper strip and foil.”

“We have built strong bonds with our NCI counterparts, demonstrating technical competence and stable product quality. This electrical and automation system will provide a foundation for growth and development in several high-tech material application fields.”

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.

Outlook For Additive Manufacturing With Copper: 51% CAGR Through 2027

Outlook For Additive Manufacturing With Copper: 51% CAGR Through 2027

Copper additive manufacturing (AM) is a rapidly expanding opportunity within the AM industry, thanks to a wave of technical developments which have begun to enable reliable, high quality printing of copper and copper alloys. As a result, commercial entities have begun to ramp up internal research and investments to capitalise on opportunities in industrial markets for copper components, with long term potential in electronics and medical devices setting the stage for copper materials to become one of the most influential in the broader metal AM industry.

According to a new market study titled ‘Copper Additive Manufacturing 2019 Market Database and Outlook’ by SmarTech Market Publishing, shipments of copper powders to additive manufacturing (AM) users grew by 45 percent in 2018, with an expected 60 percent growth during 2019. Fuelled by key technical developments in copper additive processes and materials, AM has the potential to create disruptive copper component applications in industrial markets in the immediate future, as solutions continue to be adopted and refined. From 2019 to 2027, the copper AM industry is expected to register a compound annual growth rate (CAGR) of 51 percent.

Copper printing exploration has been ongoing for many years, with published research dating back to at least 2010, according to SmarTech. The largest market catalyst came in 2016 with the development and certification of printing of copper alloys, as well as pure copper, utilising metal powder bed fusion technologies (both laser and electron beam variants) for the production of copper induction coils.

Copper materials are being explored within each of the three primary metal AM print technology families today, but their chemistry does present challenges to processing using established or ‘conventional’ metal AM system configurations in most available technologies. To overcome these challenges, SmarTech believes there are three primary avenues of technical development which are influencing the overall adoption of copper printing:

  • Alterations to or adaptations of hardware architecture of existing printing systems
  • Tailoring of material properties and powder characteristics of copper materials used
  • Development of alternative metal additive printing technologies suited to copper printing
