Excellent results after drive and control revamp at
Gerdau Sidenor Reinosa
In August 2014, Russula successfully started-up the
Gerdau Sidenor Reinosa DUO blooming mill after implementing
a drives and control upgrade. Russula was
also responsible for the engineering, installation supervision
and commissioning.
The Russula automation and control scope includes:
- Blooming control for 6 and 8 ton blooms
- Stand 2 and 3 control
- Tilting device control 1 and 2
- Sideguides 1, 2, 3 and 4 control
- Upper cylinder control stand 1
- Engineering
- Installation support
- Commissioning
The Russula Control System was constructed using a
selection of hardware chosen specifically for this project,
including a Siemens PLC 414-3DP, new Sinamics
DCM 220V (3 phase) drives, 5 remote I/Os and WinCC
HMI. All drives were delivered already mounted on
panels and then installed in the existing electrical cabinets.
The communication between the drives, operator desks
PLC and remote IOs was with profibus, while ethernet
was used to communicate the new HMI to the PLC.
As part of the software development, a new recipe system
was put into operation. The operators found the
recipes easy to modify and store for fast changes of
product dimensions, grades and shapes. Without
doubt, the revamp improved the overall productivity
and product quality of the DUO blooming mill.
Located in the municipality of Cantabria, Spain, the
Gerdau plant is dedicated to fabricating specialty steels
as well as forging and casting large turbine shafts for
shipbuilding.
