In a statement, Primetals Technologies said SSAB Hämeenlinna has signed off on improvements to the No. 1 mill stand serving the facility’s 4-stand tandem cold rolling mill. The project entailed improvements to the entire drive system, including transformers, drive and motor. 

“The project involved the manufacture of a synchronous motor that uses a new stator as well as a spare rotor and slip rings. The old oil transformers were replaced with new maintenance-free and environmentally friendly dry-type transformers. Also, the controllers and drive systems were upgraded to state-of-the-art technology,” the company said. 

With the certificate issued, the first phase of a broader project is complete, Primetals Technologies said. In the second phase, the No. 2 mill stand will be upgraded.
