Nucor Kingman bar finishing mill upgrade
In April 2022, the Russula team made an onsite visit to the Nucor Kingman mill to analyze the current state of the equipment and electrical installation in the bar exit area. The equipment scope began at the cooling bed and finishing at the tying area. After summiting a proposed E&A solution to improve performance, Nucor Kingman has contracted Russula to replace the obsolete automation and drives equipment with a new modern first line ABB ACS880, DCS880, and Siemens Sinamics S120 configuration for the servomotors of the layer extraction trolleys.
E&A Scope of Supply for Bar Mill Exit
In addition to environmental benefits, upgrading, retrofitting, and reusing existing equipment can provide significant cost savings over installing new equipment. Upgrades also minimize construction work resulting in faster installations.
In the bar mill exit area upgrade at Nucor Kingman, the existing control system hardware, cabling and the MCCs will be reused. New ABB ACS8800 series multidrives, a new ACS880 drive in stand-alone configuration for the rod block scrap roller table and ABB DCS 880 DC drives will be provided. The existing INDRAMAT servo-drive system for the layer extraction trolleys will be replaced with a Siemens solution: multidrive, motor, power cable and communication by “drive-cliq”.
In 2017 the Nucor Kingman and Russula team performed an automation upgrade on the entire wire and rod mill. Russula is honored to be selected for this project and to collaborate with the Nucor Kingman plant again.
