22,500 mm (74 ft), a width of up to 7,000 mm (23 ft), and a
height of up to 6,000 mm (20 ft). This large-sized machine made
the upper bolster for the press with a fi nal length of 9,783 mm
(32 ft), a height of 3,300 mm (10.8 ft) and a weight of 250 t
(275 US tons) almost look small.
“Very satisfi ed!”
With that much fi tting accuracy from the beginning on, it was no
surprise that the assembly and start-up took place to the fullest
satisfaction of the customer. “Very satisfi ed!” commented Werner
Finkler from Dillinger Hütte on the new straightening press. His
colleagues from the Krefeld team concluded: “The cooperation
with our colleagues from the Saarland was outstanding. For all
details and challenges that this order included, one thing proved to
be true: Man is the best computer!”

Record project – record key data
With the fi rst straightened plate on March 10, 2010,
Dillinger Hütte AG celebrated an important milestone
with the new straightening press. During production
of the press in Krefeld, two important key dates were
marked red in the calendar!
May 19, 2009: For the upper bolster of the straightening press
with a raw casting weight of 252 t (278 US tons), Siempelkamp
poured 270 t (297.6 US tons) of molten iron with a temperature
of 1,350 °C (2,462 °F). This event outperformed the
existing world record from 1998. Within two minutes the molten
iron was poured from fi ve pouring ladles simultaneously into a
mold. There, the iron solidifi ed and cooled. This procedure was
not only record-breaking but it was also spectacular to watch.
October 5, 2009: The fi nished upper bolster left for Saarland,
Germany. On a heavy-duty vehicle it was transported to the
Krefeld port. From there it went via a ship on the rivers Rhine,
Mosel, and Saar directly to the factory port of Dillinger Hüttenwerke.
