Rolling mill stands and drives upgrade at Gerdau Wilton

Engineers from AIC North America have successfully commissioned the first phase of drive upgrading at Gerdau Wilton (Iowa, USA).

The intervention has centred on replacing stands 1, 2, 3 and 11 drives, as well as starting up new converters for stands and shears. Shears (SH1 & SH3) drives and control, approach roller table to stand 2, pinch roll 3 and VF0 roller table drives were all part of the project.

Shears controls as well have been completely migrated from obsolete axis control to the new ControlLogix platform with motion controls and Safety PLC has been installed to improve the safety LOTO procedures at the site; everything interfaced with the Rolling Mill Control system platform installed at the site.
