The cast steel Gröditz GmbH was a foundry in Saxony Gröditz . It manufactured cast steel parts using hand-molded casting processes for shipbuilding, energy engineering, in offshore applications, mold making and general mechanical engineering with a cast part mass of up to 52,000 kg in unalloyed and alloyed degassed steel material qualities (VD / VOD steel). The liquid steel was obtained from the neighboring electric steelworks using pouring ladles via a cross-track connection. The heat treatment of cast parts made of tempering materials with oil or water hardening was carried out in the forging works in Gröditz .
With around 70 employees, cast steel parts with maximum dimensions of 6000 × 4500 × 2800 mm or a maximum diameter of 4000 mm and a height of 2800 mm could be produced by March 2015 .
history
The history of steel processing in Gröditz began in 1779/1780 with the founding of the Gröditz ironworks by Cabinet Minister Count Detlev Carl von Einsiedel . The foundation stone for a cupola furnace was laid on September 5, 1818 . The first melting and the first casting from the newly built cupola in the presence of Count Detlev Carl von Einsiedel took place on May 19, 1819. In 1830 a wing was added to the blast furnace for the clay molding shop and in 1838 a decorator's workshop was set up for the foundry; a new cupola fair was also performed. In 1843 the foundry was enlarged by building a new workshop.
In 1872 the various Gräflich Einsiedel works and thus also the Gröditz plant were owned by the Lauchhammer stock corporation . A new test and asphalt building was built for the pipe foundry I. Under the direction of the metallurgical master and later professor for metallurgy at the Bergakademie Freiberg, Adolf Ledebur , the construction of the pipe foundry II began.
Cast steel was added as a new branch of production in 1901. On January 23, 1902, the first good cast steel from the Bessemer pear for mine car wheels was cast. The first converter held a load of 300 kg. In 1905 a workshop was built to process Bessemerstahlgusses. The steam power previously used for the operations was replaced by electrical systems.
In 1906 the cast steel processing workshop was enlarged by adding a special cast steel cleaning shop and in 1915 the construction of Siemens-Martin ovens began. During the First World War , weapons production (artillery projectiles and gun parts) was massively expanded.
In 1922 the ironworks was acquired by Linke-Hoffman-Lauchhammer AG and in 1926 it became the property of the Flick Group . From 1939, the steelworks became an armaments factory in World War II and were part of the Mitteldeutsche Stahlwerke AG von Flick . In this context, forced laborers were also used in the company.
After the occupation of Gröditz, it was dismantled by the Soviet occupying forces between 1945 and 1947 . In 1947 the policy of dismantling was abandoned and reconstruction began. In 1952 the first electric furnace for steel melting was started up.
In 1948 the company was nationalized as VEB under the name VEB Stahl- und Walzwerk Gröditz . In 1990 the Treuhandanstalt took over VEB with 5,300 employees at the time. The VEB Stahl- und Walzwerk Gröditz became the Gröditzer Stahlwerke GmbH with forge , ring rolling mill , steelworks and foundry . At a cost of 150 million DM (according to today's purchasing power 128 million euros), the outdated systems were completely modernized.
In 1997 the company was taken over by Georgsmarienhütte GmbH and in 2002 it was organized as a division of Georgsmarienhütte Holding GmbH as Schmiedewerke Gröditz GmbH.
The foundry had been independent since August 1st, 2004. Since then it has operated under the name Stahlguss Gröditz GmbH within the steel casting machine construction division of Georgsmarienhütte Holding GmbH . The last batch was cast in the molding shop on March 5, 2015, and parts delivery ended in the summer of 2015.
