Stahlwerk Thueringen, Germany, orders new roughing stand
Apr 14, 2009
Stahlwerk Thüringen GmbH, a company of the Spanish Grupo Alfonso Gallardo, has placed an order for a new roughing stand for its long product mill in Unterwellenborn, Germany.
The existing breakdown stand has been in operation since 1985 and is to be replaced with a more flexible stand due to the constantly growing demands on the breadth of the product range. It will enable in particular heavier and larger sections to be produced efficiently and with high profitability.
The new stand is designed for a rolling force of 10,000 kN and has a drive power of 4,400 kW. Further technical features include i. a. the automatic roll gap opening in the event of an overload, the semiautomatic axial shifting of the top roll for pass adjustment and the significantly simplified roll changing.
The modernization measure includes not only the new roughing stand, but also the replacement of the whole drive train, work roller tables and side guard manipulators as well as the complete electrical and automation equipment. The plant is now in a position to meet the growing demands on productivity, flexibility and profitability of long product rolling mills.
Commissioning of the new plant is scheduled for December 2010.
