DHHU 15000 t forging press.


At the end of the 2nd World War, the two largest forging presses in the world were located in the Ruhr area in Germany.
One, a 15000 ton 3-cylinder steam press, was located at Krupp in Essen and had also been built there in 1928.
The other was a 15000 ton 2-cylinder compressed air press built by Kreuser-Wagner in Dortmund.
This press was installed in 1932 at Dortmund-Hörder Hüttenunion.
The Krupp press went as reparation to Yugoslavia where it was later scrapped.
The DHHU press was dismantled in 1951 and sent to England where it was never rebuilt either.

With the help of an ancient plan I was able to locate the exact position of this press on the former Union site by now.

PILSEN STEEL

The steel mill in Pilsen was founded in 1859 by Ernst Graf Waldstein-Wartenberg.
In 1869 it was taken over by engineer Emil Ritter von Škoda.
In the 20th century it became the largest industrial company in Czechoslovakia producing steel, forgings, machinery, cars, tanks and guns.
In 2004 the steel making, forging and foundry branch was split off and sold to a Russian company.

Scana Steel


The steel mill in Söderfors, Sweden dates back to an old anchor forge founded in 1667.
In the 19th century the forge was extended by steel making and rolling mills and became part of Söderforsgatan Bruks AB.
In 1907 the plant was sold to Stora Kopparberg Bergslagen.
The Söderfors works merged with Fagersta AB in 1982 and were taken over by the French Eramet Group ten years later.
The eastern part of the site (rolling mill, forge and foundry) were sold subsequently to Scana Steel and the Akers group.
Scana Steel today runs a medium section rolling mill, a hammer forge and a 1000 ton forging press in Söderfors.

Buderus Edelstahl Revisited


Additional images now at Stahlseite.
The Wetzlar works were founded by “Röchlingsche Eisen und Stahlwerke” and Buderus in 1920.
A new melt shop was erected in 1939.
In 1965 Buderus took over and in 2005 the Austrian steel company Böhler Uddeholm acquired the mill.
Nowadays Buderus Edelstahl produces about 300000 tons of crude steel in an electric arc furnace. All steel is casted into ingots.
The further production line includes a blooming mill, a hot strip rolling mill, three open die forging presses and a closed die forge.

L’Usine De Thionville


Though much of Lorraine’s steel industry has vanished the old Carlshütte in Thionville is still around. At least parts of it. Like the electric arc furnace in the old open hearth shop now owned by Akers from Sweden.
Further viewing at stahlseite.

The mill in Thionville (German: Diedenhofen) on the banks of the river Moselle was founded by Carl Röchling from Völklingen, Germany and named “Carlshütte” in 1898. Lorraine was part of Germany from 1871 to 1918. Two blast furnaces were built and two more plus a Bessemer steel mill were added in 1906.
After the first world war the mill became French and was now called “Société Lorraine Minière et Métallurgique”.
A coking plant came into operation in 1928.
The “Aciéries de Longwy” took over the plant in 1933.
A forge, an open hearth melt shop and a foundry were added.
1953 saw a new owner: “Société Lorraine – Escaut“.
In 1964 blast furnace number 1 was replaced by a new furnace the largest in Lorraine capable of producing 2000 tons of pig iron a day. Furnaces No. 2,3 and 4 were closed down in between 1966 and 1970 and were all dismantled by 1972.
USINOR a large steel company from northern France took over the Thionville mill in 1966.
A new UHP 70 ton electric arc furnace replaced the old open hearth furnaces in 1973.

Plans to built a OBM oxygen steel making shop on ground were halted in the 1970ies and in 1977 the blast furnace, the Bessemer shop and all rolling mills were closed down for good.
In 1980 a new continuous caster was installed to supply feedstock for USINOR’s
wire rolling mill in Longwy.
In 1983 the steel foundry was closed down.
In 1985 the mill was split up into USINOR Acierie de Thionville and USINOR Forge de Thionville.
USINOR and SACILOR, the two largest steel groups in France were fusioned in 1986, now government owned.
The steel mill became part of Unimetal (the long product subsidiary of USINOR) while the forge became part of the USINOR/Cockerill owned rolling mill manufacturer Forcast.
The continuous caster was closed in 1994 and the steel mill was now taken over by Forcast.
Forcast was sold to the Swedish roller manufacturer Akers in 2001.
Akers still runs the 70 ton electric arc furnace, ingot casting and the 4000 ton forging press to produce ingots and forged rolls mostly for the steel industry.
