Stahlwerk Thüringen GmbH recently has commissioned the new roughing stand supplied by SMS Meer, Germany, for the section rolling mill in Unterwellenborn.
The new two high reversing stand is designed for a rolling force of 10,000 kW and has a drive power of 4,400 kW. Further special technical features include the automatic roll gap opening in the event of an overload, the semi-automatic axial shifting of the top roll for groove adjustment and the significantly simplified roll changing.
The plant standstill time for the modernization was just six weeks. The old roughing stand was dismantled and the new stand installed. It includes a complete drive train, working roller tables and side guard manipulators as well as the complete electrical and automation equipment. The new rougher replaces a stand that has been in operation since 1984.
Stahlwerk Thüringen belongs to the Spanish Alfonso Gallardo Group.
