Annual report 2009 - Siempelkamp

From energy conversion to press construction: the foundry is involved!
Just as versatile as the production process of castings made of nodular graphite cast iron are the application areas and industrial
sectors where the Siempelkamp Foundry has positioned itself.
Primarily companies from the fi eld of energy conversion demand products made by Siempelkamp Foundry. Traditionally we are working
together with our subsidiary Siempelkamp Nukleartechnik GmbH (SNT) in this area. On behalf of SNT we manufacture the thick-walled
CASTOR ® container made of nodular graphite cast iron. The CASTOR ® , a product of the GNS, is used for the transport and interim
storage of spent fuel elements and highly radioactive waste. The requirements on the material and structural composition are
correspondingly high. The exact process management during the manufacturing process at the Siempelkamp Foundry guarantees a
reproducible manufacture of this highly-tested and sophisticated casting. The different types of the CASTOR ® containers have raw cast
weights ranging from 80,000 kg to 150,000 kg (88 to 165 US tons) with a wall thickness of up to 600 mm (24 in).
Industries and markets in 2009:
a diverse production mix
Due to our broad range of products Siempelkamp Foundry supplied
a total of eleven different industries in 2009. Four important
industrial sectors stand out. 40% of our castings were supplied
to customers in the area of energy conversion. A 25% share can
be allotted to the market for mill building, 20% to general machine
building, and 15% of our castings were used in press construction.
