Commissioning
Upgrading the mill train at Hoesch Schwerter Profile GmbH,
Germany, was a special challenge for both the operator and
the machine builder SMS Meer. What made this job so special
was the three-stage modernization concept, enabling shutdown
periods to be minimized to the greatest possible extent
and ongoing production of the mill between short shutdown
periods.
Ambitious goals. In August 2007, Hoesch Schwerter Profile
GmbH, a member of Calvi Holding, Italy, had commissioned SMS
Meer to upgrade the mill train for special sections. The goal was
to increase the availability, the yield and the flexibility as well as
to improve the quality of the finished products.
New CS® mill stands. The modernization concept perfectly tailored
to customer’s demands comprised an exchange of the existing
universal and two-high mill stands with the CS® mill stands
(Compact Stands) developed by SMS Meer. These stands offer automatic
quick changing for an increase in flexibility and a reduction
of setup times as well as a compact design, very high stand
rigidity and high adjusting accuracy. Key assembly groups such as
the adjusting equipment could be standardized for all stand types.
Customized mill stand solution. The CS® concept enables a high
flexibility and is optimally suited for the requirements when rolling
special sections. For this customized mill stand solution it was considered
that the existing rolls and guides could be re-used. As a result,
the special section mill became notably efficient. In total, four
universal and four two-high stands as well as one edger were supplied
and an existing edger was upgraded. The four universal
stands were pre-assembled in our workshop and the complete
stand piping was mounted.

”Just like an open-heart surgery”
Hoesch Schwerter Profile:
Modernization in three steps
Universal stand pre-assembled in the Mönchengladbach workshop.
Extensive ancillary facilities. Likewise modernized were descaling
and centering devices as well as grip-type tilters ensuring optimal
conditions of the rolled material when special sections are
rolled. Our scope of supply included also the mill stand changing
devices and the assembly area in a new pre-assembly workshop
for stands and the required supply systems as well as the electrical
equipment and the automation for the new facilities. The IBA-
Logic system in version 4 was applied first for the whole control.
The implementation was realized by Fest, our electrical equipment
partner, on our behalf.
