A Farewell To Steel Making In Bochum


A history of more than 170 years of steel making ended in Bochum, Germany in late June when the Nirosta stainless steel plant was closed for good.
The original BOF shop was built in 1957 by the Bochumer Verein to be only the second of it’s kind in Germany.
In 1972, after the closure of the blast furnace site both vessels were transformed into AOD converters and an electric arc furnace was installed in the same building to produce stainless steel.
In 1982 a huge new 135 MVA electric arc melt shop was attached and the old EAF was replaced by a ladle furnace.
I payed the site a final visit before the demolition started.

installed motor capacity makes the ThyssenKrupp hot strip mill in Bochum  the most powerful rolling mill in Germany. Though the mill was already planned in the early 1960ies by the Bochumer Verein steel corporation it wasn’t until 1966, after the takeover by the Fried. Krupp company, that the mill was put into operation.
The mill is capable of rolling even high alloyed speciality steel.
After the closure of the adjacent Nirosta steel mill all primary material now comes from the August Thyssen Hütte in Duisburg.

Narrow Strip Mill


After more than 10 years I visited my hometown’s unique narrow strip mill again.

The rolling mill in Hohenlimburg, now part of the city of Hagen/Germany, was founded in 1846 and goes back to the old Böing  forge, a descendant of this family later founded the Boing aircraft company in Seattle, USA.
The mill produced wire and later hot strip.
In 1907 the site was taken over by the Hoesch steel company from Dortmund.
In the 20th century numerous cold rolling , wire drawing and steel spring manufacturers were taken over.
In 1955 the new narrow strip mill started it’s production.The Hohenlimburg site was fusioned with Schwerter Profileisenwalzwerke AG in 1969. This rolling mill was sold to the Italian Calvi group in 2005.
The Hohenlimburg plant is now part of ThyssenKrupp Steel.

Wheels Of Steel


The rolling mill in Königswinter, Germany was built in 1957 by the Lemmerz Werke GmbH
producing wide flats for car wheels.
In 1997 Lemmerz merged with the U.S. based Hayes Wheels International company to form Hayes Lemmerz.
In 2010 the rolling mill was outsourced and proceeded under the new name “Warmwalzwerk Königswinter”.

Steel Foundry


The steel foundry in Wetterzeube, Germany was founded in 1909 named „Stahlwerk Staeglich und Haberkorn Wetterzeube“. The foundry operated a cupola furnace and two crucible furnaces. These were replaced by an open hearth melt shop in 1921.
After the war the Wetterzeube works were nationalized and became part of the “VEB Stahlgiesserei Elstertal Silbitz” foundry combine in 1955.
In 1985 a 5 ton electric arc furnace, built in the 1950ies and relocated from Bösdorf near Leipzig, was installed.
After the privatization the Wetterzeube foundry became part of the GEW Gestaguss group from Velbert, Germany.

TKS Heavy Plate Mill, Duisburg


The heavy plate mill in Duisburg-Hüttenheim, Germany was built by the Mannesmann company in 1963 to supply plates to their adjecent large diameter pipe welding mill (closed in 1978).
In 1970 the August Thyssen Hütte AG took over the flat rolling business from Mannesmann.
In 1978 the Sack company installed the 3,9 meter four-high rolling stand still in use today.
