The ArcelorMittal Bremen GmbH is part of the ArcelorMittal Corporation and operates a steel plant in Bremen.
history
In 1908 the Norddeutsche Hütte was built. Pig iron was produced using two blast furnaces, which was further processed into steel in the Ruhr area. The Admiral colliery in Dortmund has been part of the smelter since 1918 and supplied the coal for the company's own coking plant. Line 11 of the Bremen tram led to the factory gate since 1926. During the German rearmament during the Nazi era , many slave laborers worked in the hut. After the end of the Second World War, the blast furnaces were dismantled.
In 1954, Klöckner-Werke AG took over the remnants of Norddeutsche Hütte AG and began purchasing the surrounding land. An integrated steelworks was to be built on the former village of Mittelbüren in the north of Bremen. Integrated means that the blast furnace , steel production and rolling mills together form a steel mill in one plant .
Production started in 1957. The plant now consisted of a blast furnace, a steel mill, a hot rolling mill and a cold rolling mill. Due to its favorable location on the lower reaches of the Weser , the ironworks quickly got the unofficial name of the “hut by the sea”. Since then, the work has been known colloquially for short as Klöckner . The location of the plant has advantages for the transport of coal and steel, since the more cost-effective route can be used by water (port) or land (rail, road).
In 1965, the Mittelbüren power plant began operating on the smelter site in the immediate vicinity of the blast furnaces. As fuel for this by swb operated traction current power plant products resulting from the production of steel are used dome gases blast furnace gas and converter gas .
Until 1968 the steel mill was operated according to the Siemens-Martin process . Then the conversion to the Linz-Donawitz procedure took place .
Until the end of 1979, a regular bus service to Bremerhaven was offered by Verkehrsgesellschaft Bremerhaven AG (VGB).
In 1985, the ingot rolling mill I was sold to Reiner Brach GmbH & Co. KG after it had been shut down two years earlier when the ingot casting line was closed.
In 1993 a galvanizing line, BREGAL (Bremer Galvanisierungs GmbH), was put into operation.
In 1994, the Belgian SIDMAR NV from Ghent , which belonged to the Luxembourg Arbed group, became the majority shareholder . The former Klöckner-Hütte Bremen was renamed Stahlwerke Bremen .
In 2001 a second hot-dip galvanizing line (BREGAL 2) was completed.
In 2002 the steel groups Arbed (Luxembourg), Aceralia ( Spain ) and Usinor ( France ) merged to form Arcelor SA with headquarters in Luxembourg and at that time formed the world's largest steel group with an annual crude steel production of around 44.0 million tons.
On March 16, 2006, the company name was changed to Arcelor Bremen GmbH in the Bremen commercial register .
The capacity of today's iron and steel works is around 4 million tons per year, which are produced by around 3,100 employees. On January 11, 2006, the production of 100,000,000 tons of rolled steel since the founding of the smelter was celebrated.
In 2007 Arcelor merged with Mittal and the ArcelorMittal public limited company was created .
The new administration building was moved into in summer 2007.
production
The main energy source for steel production in Bremen is coal. Coal and iron ore are usually delivered by ship. In the course of technical development, coal dust has proven to be particularly effective in controlling the manufacturing process. Therefore, the coal is finely ground. Coke, sinter and other additives are also used. The first stage of production takes place in the blast furnace . The molten pig iron is poured into a ladle car (a so-called torpedo). This goes to a converter , where ferrous scrap is also recycled. The scrap is roughly sorted in Bremen, separated by magnets and melted in the converter. In the second stage, the required steel grades can be obtained in the converter with precisely calculated additives. In a vacuum system, as much carbon is extracted from the converter as is necessary for a certain quality of steel . The liquid steel is then poured into slabs using the continuous caster . The further processing of the slabs takes place directly warm or later cold in the hot rolling mill into hot strip , rolled into coils . This is followed by further processing into cold strip in the cold rolling mill , also rolled up into coils. The end product after the cold rolling mill is flat steel in the form of rolled up sheets ( coil ). The cold strip coils are hot-dip galvanized or even processed into galvanized blanks ( tailored blanks ) , depending on customer requirements .
Managing directors
The management of ArcelorMittal Bremen GmbH consists of four members who manage the location. The managing directors are Reiner Blaschek (Chairman) and Dirk Francis (“Primary” division). Andreas Dalchow (Technology, Finishing) and Jens Loock (Labor Director).
