The Last Blast Furnace In Duisburg-Ruhrort.

Hochofen 6 Thyssen in Duisburg Ruhrort.
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.

Dreischeibenhaus

Phoenix-Rheinrohr AG built its spectacular new headquarter (the “Dreischeibenhaus”) in Düsseldorf 60 years ago.
The 2400 ton steel structure was 95 meters high and designed by local architects Helmut Hentrich and Hubert Petschnigg.
In 1964 Thyssen took over the house before moving to Essen in 2010.

The Thomas Steel Works in Liege-Ougree

 Thomas Steel mill Cockerill-Ougree
With the construction of three new steelworks at the end of the 1950s, the Thomas steel making process (Basic-Bessemer) experienced its technical peak and a final blossoming.
Between May 1958 and August 1959, HADIR in Differdange, Phoenix Rheinrohr in Duisburg and Cockerill-Ougree in Liege commissioned a total of 13 converters with tapping weights between 50 and 70 tons.
All of them had been planned and built by DEMAG in Duisburg.
Plan Thomas Steel Plant Cockerill Ougree
The Thomas steel plant in Liege-Ougree, with its futuristic façade at that time,
will remain the last new construction of its kind in the western world.
Five 56 t Thomas converters and two 1500 t hot metal mixers were put into operation on 4 August 1959 and were supplemented by a 60 t LD-AC converter in 1962.
In December 1975 the Thomas steel works in Liege were shut down.
5 years later the use of the basic bessemer process in the western hemisphere was finally terminated.
