Nucor Steel has selected Primetals Technologies to upgrade the automation and drives system in the finishing end of its carbon plate steel mill in Cofield, North Carolina, USA. Equipment in the finishing end includes the side trimmer, cold shear and plate piler. The project also contains an option for future implementation of a quality assurance system. The upgrade will be completed in May 2017.
Built in 2000, the Hertford County mill produces 1.6 million tons of carbon, alloy and high strength, low alloy steel plates including quenched and tempered and normalized steel plates. The plate mill produces plate for many products, including armored personnel carriers, railroad tank cars and bridges. Primetals Technologies will replace the mill’s existing drives and control system with Siemens drives, automation and human machine interface (HMI), a WinCC software system, and a level 2 automation system to control the mill’s side trimmer, cold shear, and shipment prep areas. Nucor is also considering an option to add a quality assurance solution with a character-recognition camera to validate customer data on metal plates.
A Fortune 500 company, Nucor is the largest manufacturer of steel products in North America, with approximately 200 operating facilities, including wholly owned subsidiaries Harris Steel, The David J.
