Primetals Technologies receives final approval on drives upgrade for Nucor Steel Arkansas hot strip mill
Primetals Technologies has received the Final Acceptance Certificate (FAC) for its F5 and F6 main drive upgrade project with Nucor Steel Arkansas of Armorel, Arkansas. This completes the third phase of the total project: full replacement of the hot strip mill’s six main mill stand drives.
The main challenge in replacing the drives was to execute the changeover within the customer’s nine-day maximum outage time. To meet this extremely tight timeline, the very large drives had to include identical take-over points for all existing, equally large cables. The new Siemens Sinamics SL 150 drives also needed to start up and achieve full production immediately, without any ramp-up time. The team achieved hot commissioning 15 hours ahead of schedule.
