AICNA for rougher mill stands drives upgrade at Gerdau Whitby
The AIC American team has led the restart at the Whitby structural mill in Toronto, after the drive cabinet and PLC/HMI modifications for the replacement of the Rougher DC drives and the conveyors 2H-3H AC drives.
All drives were engineered in the same way as the Bar Mill supplied by AIC in 2018.
Namely, the modifications included the 4 rougher stands replacement with the new ABB's DCS880 drive panels. Within the project, 4 converters with master/follower configurations were added and the three conveyor stands between stands 2-3 were also replaced with ABB's ACS880 modules.
The upgrade of the existing automation & control system led to full control of the rougher stands and of the conveyor drives. Drives alarms and interfaces were added to the existing HMI platform.
The site is owned by GERDAU GLN (part of Gerdau Group) for rebar products.
