Following the recent modernization of the DC drives of the Cartersville mill in just six days, Gerdau upgraded the existing control system and HMI architecture at the Cartersville plant, together with Russula.
The scope of the control upgrade included all the controls equipment from the first stand to the cooling bed. The current ABB AC450 PLCs and ABB AS500 SCADA operator inferface were replaced with the ABB AC800M series and Wonderware Intouch. Russula mill control was implemented for the entire mill.
The new bar mill control and HMI architecture was implemented during a planned shutdown in September, 2015 along with the upgrade of one of the strands of the four strand continuous caster.
