Long-product mills
For heavier and larger steel sections
Stahlwerk Thüringen orders
new roughing stand
New order
The old roughing stand.
Responding to an order from Stahlwerk
Thüringen GmbH, a company of the Spanish
Grupo Alfonso Gallardo, SMS Meer will supply
a new roughing stand for the long-product
mill in Unterwellenborn. This powerful rougher
will replace the existing breakdown stand
which no longer meets today’s requirements
owing to the heavier and larger sections
which the customer has added to the mill’s
product spectrum. Commissioning is scheduled
for December 2010.
The new mill stand will be designed for a
rolling force of 10,000 kN and will have a
drive power of 4,400 kW. Further special
features include automatic roll-gap opening
in case of overload, partly automated axial
shifting of the top roll for groove or pass
adjustment and facilitated roll changing.
In addition to the new roughing stand, the
modernization scope includes the renewal
of the whole drive train, the work roller tables,
the sideguard manipulators and the
complete electrical and automation equipment.
On this rolling mill which SMS Meer supplied
in 1985 Stahlwerk Thüringen GmbH
produces more than 200 different steel
sections. The long-product mill has an annual
capacity of over 900,000 t.
The finishing mill modernized in 2003 with our
patented CCS ® mill stands in tandem arrangement.
