Bulletin 2/2010 - Siempelkamp NIS

SIEMPELKAMP | FOUNDRY/MACHINERY AND PLANTS
steam engines, steamships and mining pits carry the title. The
press has a height of 26 m (85 ft) and a weight of approx. 8,000 t
(8,818 US tons). That is enough steel to lay 65 km (42 miles) of
modern railroad track. Some of the nuts used to hold the press
together weigh 55 t (61 US tons) each. The forging pressure of
45,000 tons is equivalent to the pressure that would be exerted
by the weight of a steel ingot higher than the Cologne Cathedral,
placed on the press table of 24 m² – so much said in relation to
the size of this ‘Super Giant’.
Big player needed!
As the world’s only manufacturer with the knowledge to design
presses of this magnitude and the ability to produce castings of
this size made of ductile cast iron in its own foundry, Siempelkamp
received the order to produce the new structural parts. As
part of the order, Siempelkamp cast ten structural parts for the
press with weights between 200 and 245 t each (220 and 270
US tons) in the company-owned foundry in Krefeld. An additional
four parts had piece weights of 70 t and 140 t each.
