The Gienanth iron foundry in Eisenberg, Germany, founded in 1735, is one of the oldest working industrial enterprises in south-western Germany.
Today the foundry runs a 30t/h hot blast cupola furnace, installed in 1978, four induction furnaces and three 60 ton holding furnaces.
Major products are blocks for stationary and ship diesel engines.
50 years ago August Thyssen Hütte AG built the largest blast furnace in Europe at its plant in Duisburg-Ruhrort.
Blast furnace 6 had a hearth diameter of 11 metres, a volume of 2200 m³ and a total height of 100 metres. It was relined and modernized in 1983. Less than two weeks after the commissioning of the second blast furnace in Duisburg-Schwelgern, blast furnace 6 was shut down on November 9, 1993.
One year later, the 19,000 ton blast furnace was dismantled and shipped to India.
In 2000, the blast furnace was put back into operation 30 km south of Mumbai at Nippon-Denro-Ispats Dolvi works. Now called Dolvi No. 1.
In 2010, Ispat was acquired by JSW Steel.
In 2016, the former blast furnace 6 was replaced by a new 4.323 m³ furnace in just 4 days using the so called single block method.
Noch 1960 ließen sich die Hamburger Gaswerke von Koppers in Essen eine nagelneue Kokerei in den Hafen (Kattwyk) bauen.
Sie versorgte zusammen mit der benachbarten Kokerei Grasbrook Hamburg mit Stadtgas und Gaskoks.
Nach dem Siegeszug des Erdgases wurden die Kokereien Grasbrook und Kattwyk 1976 u. 1982 stillgelegt.
The former National Steel BOF shop was demolished last week.
The basic oxygen steel making shop with it’s 330 t vessels
