14/38. Birlenbacher Hütte, Schleifenbaum

1959 gab es in der Bundesrepublik Deutschland noch 156 Hochöfen an 38 Standorten. Alle Standorte und alle Hochöfen sollen in dieser Serie im Kurzportrait vorgestellt werden.

Die 1453 gegründete Birlenbacher Hütte in Geisweid, heute Siegen, stellte 1959 in zwei kleinen Hochöfen kalterblasenes Spezialroheisen her. Dabei wurde der Hochofenwind auf nur circa 300-400° vorerhitzt. In einem nachgeschalteten E-Ofen konnte das Roheisen dann im Duplexbetrieb weiter veredelt werden. Das Eisen ging dann in der Regel an Gießereien.
1971 wurde die Hütte als einer der letzten Kleinbetriebe seiner Art in Deutschland stillgelegt.
Die Birlenbacher Hütte erzeugte 1959 33.741 t Roheisen.

Sheet Rolling Mill


Sheet metal has been rolled at the Siegen-Geisweid site since 1846.
VDM-Metals GmbH’s current quarto plate rolling mill was commissioned in 1977 by Stahlwerke Südwestfalen.
For this purpose, a DEMAG cold rolling stand dating from 1954 was converted into a hot rolling mill.
After a fracture in the roll stand the SMS Group replaced it with a new 2.7 m four-high stand in 2013. The drives were taken over.
In Siegen, VDM-Metals rolls high-alloy speciality steels which are mainly produced in ingot casting in Unna and rolled into slabs in Duisburg.

Roller Capital

Though the blast furnaces are long gone, the town of Siegen in Germany is still the capital of roller production. Five foundries still cast rollers for the steel industry, paper mills and other industries.
One of them is the Karl Buch roller foundry.
The company was founded in 1855 by Karl Buch and is located in Siegen- Weidenau since 1867.
The foundry produced alloyed rollers since 1920. In 1955 the cupola furnaces were replaced by modern electric furnaces.
Since 1984 a vertical centrifugal caster for rolls up to 60 tons is in use.
Today rollers up 85 tons can be casted statically.
The foundry is still owned by the Buch family.
