Outokumpu grants SMS group final acceptance for mill modernization
by David Fleschen
Outokumpu Stainless has issued the final acceptance certificate (FAC) to SMS group following the successful modernization of its Steckel mill at the company’s Tornio facility. The upgrade is expected to secure the long-term operation of the mill while reducing maintenance requirements and downtime.
The modernization focused on replacing obsolete equipment and improving key areas of the plant, including the foundations, pinch roll unit, and side guides. The project involved the integration of new roller tables with side guides, advanced motors, and a new pinch roll unit complete with a drive train and modern hydraulic systems. The new components were mounted on a steel structure, replacing previously deteriorated concrete blocks.
A significant challenge was integrating the new equipment within the plant’s limited space. SMS group developed tailored solutions to ensure the upgrades fit seamlessly into the existing infrastructure while meeting Outokumpu’s operational requirements.
“We are very satisfied with the implementation and results of the modernization measures,” said Seppo Lantto, Manager Hot Rolling – Hot Rolling Mills, BA Europe, Tornio Operations. “In addition to making the plant more future-proof, we have reduced maintenance efforts and downtime caused by obsolete equipment. The improved availability of the plant has been particularly impressive.”
The modernization was completed with only four weeks of downtime. After the main shutdown, new installations, pipework, and cabling were completed. Operations resumed on November 19, 2024, followed by an eight-week test phase during which all agreed performance parameters were achieved. Lantto confirmed that the availability of the new equipment reached 99.8 percent during the test period.
The final acceptance certificate was signed during a ceremony in Tornio. Both Outokumpu and SMS group have since begun exploratory discussions on potential future projects.
Outokumpu has operated the Steckel mill at Tornio since 1988, with frequent modernization efforts carried out in collaboration with SMS group since 2000 to maintain the facility’s technological edge.
