Finalizada la primera fase de la modernización del CSN
Russula is pleased to announce that the first phase of the automation and drives modernization for the two-strand continuous slab caster was successfully completed and put into operation at Companhia Siderúrgica Nacional (CSN). The existing drives were replaced with a top-of-the-line model ABB DCS880. Fifty-eight drives were retrofitted in three days. Verification, testing and commissioning took another three days for a record total downtime of six days.
58 drives retrofitted in just six days
Phase 1 project plan
Before the new drives were installed, the PROFIBUS DP and Ethernet networks were tested during the scheduled weekly maintenance shutdowns. Russula provided training and an installation manual, containing connection drawings, to the CSN team. All the cables and modules of each of the 58 drives were color and code tagged to be able to identify network nodes and casting strands.
Russula pre-fabricated drives kit for quick replacement
Russula was responsible for the pre-assembly, energization, parameterization and application development of the new ABB DCS880 drives. An existing control system study was also performed.
Phase 2, modernizing the automation system, is currently underway. The commissioning is scheduled for August, 2022.
