Approximately one day was allotted for
the melting process – a long time compared
to the 120 seconds needed for the
casting process. In this historical moment
the performances of the foundry team
and the experts from the machinery and
plants division within the Siempelkamp
Group met: “Even though we already have
experience with world record castings,
the stress level among all participating
employees was high. The good work of
the experienced team provided us the
security to handle these dimensions
successfully,” says Stefan Mettler, Technical
Manager Siempelkamp Foundry.
After the casting process, the upper press
beam inside its sand mold required
approx. three and a half weeks to cool
down to a temperature of approx. 300°C
(572°F). At the beginning of August, the
beam was then transported from the
molding bay to the fettling shop where
fi nish work was performed for approx.
three weeks. Afterwards, the press beam
was fi nish-machined on one of the world’s
largest portal milling machines and fi nally
had to undergo a quality inspection.
Resulting from these process steps, the
casting now met the required weight limit
