Ahead of schedule, after the annual stoppage, interventions of the TB bar mill in Aosta were successfully completed, and work involved the 8 existing stands 3-6 and 9-12.
Principal issues concerned obsolete equipment and TB dependability; thus the upgrade involved the drives and motors and the integration of the renovated Siemens SINAMCIS S120 800kW modules. The dismantling of old switchboards/transformers and repositioning of upgraded models clears the way for more precise equipment management.
The revamping occurred before the deadline and ran smoothly thanks to AIC team resilience and adaptability to events and to the existing PLC- connected to 2 different suppliers with different standards (S5 and S7).
Phase 2, scheduled for 2023, will see the completion of work for an additional 6 stands in order to guarantee total flexibility for the entire rolling production potential and even greater performance.
