DILLINGER/SIEMPELKAMP VALVES Perfect interaction 500 MN drop-forging press puts on the pressure - with heavy plate from Dillinger
(Left and below left) Dillinger Hütte supplied 510 millimetre thick heavy plates with sophisticated mechanical properties to Siempelkamp for the 500 MN drop-forging press.
set two records simultaneously with its construction of a 50,000 tonne drop-forging press: the casting of 320 tonnes of molten iron in the group’s own foundry for the largest press of its type manufactured up to now in Germany broke the previous world record. Capabilities that the project suppliers also had to keep pace with.
K Once again, Siempelkamp put its trust in heavy plate from
refeld’s press specialist Siempelkamp Maschinen- und Anlagenbau GmbH
Dillinger. Europe’s market leader in the extra-thick plate sector for the first time supplied plates of 510 millimetre in thickness for the pressure distribution plates and the drive table of this mega-scale press. Despite the extreme plate thickness, Dillinger nonetheless guaranteed mechanical properties as specified under the EN 10025 standard for plates up to a maximum thickness of 400 millimetre. Concentrated high-level capability from two top companies in their fields, and thus optimum preconditions for a press which is to operate with both high precision
and extreme reliability for many decades as the central element in a new forging plant for China’s Nanshan Group.
Siempelkamp, a global player
in the supply of technological equipment, with 3,000 employees, of whom 950 in Krefeld, specialises in four main fields: not only all-in systems for processing of wood and wood-based materials, but also special presses for the rubber industry, composite systems and large-format presses for metalworking. At its Krefeld headquarters, single-source design, engineering, construction,
transportation, installation and commissioning assure maximum possible reliability for the production process and the product. This is also confirmed by the many projects successfully completed by this expert in XXL- size drop-forging presses. The company has now once again demonstrated its outstanding capabilities internationally with the supply of a 50,000 tonne drop- forging press for a subsidiary of China’s Nanshan group: Nanshan Aluminium is among the leading users of aluminium and titanium alloys for the production of structural components for use in the aerospace industry. Nanshan commissioned Siempelkamp to construct a complete 500 MN large- format press for a new forging plant at Longkou, in China’s Shandong Province. The decisive factor in the award of the order to the Krefeld technology wizards was, in particular, Siempelkamp’s proven capabilities in the casting of large components and in subsequent machining of the extreme item weights involved. Nanshan uses the largest drop-
The production of heavy plates with a thickness of 510 millimetres was a first for Dillinger Hütte.
