ArcelorMittal Hamburg

The plant was founded in south Hamburg in 1970 by Willy Korf as “Hamburger Stahlwerke” (Hamburg Steelworks). In 1995, the plant was taken over by Mittal Steel. As a result of the merger between Arcelor and Mittal Steel, it belongs since 2007 to the ArcelorMittal Group.

ArcelorMittal Hamburg has about 560 employees on its payroll who, through their vocational competence and dedication, contribute decisively to the success of the company. ArcelorMittal Hamburg GmbH is one of the leading producers of quality wire rod in Europe. Its production spectrum includes welds, high carbon steel, cold upsetting grades, as well as free-cutting steel and other products. A total of about 250 different grades of steel are produced.

The actual steel production takes place in a steelworks that consists of an electric arc furnace, two ladle furnaces and a continuous casting line. To modernise, one of the most powerful electric oven transformers in the world was installed in 2008, allowing production capacity to reach approximately 1.1 million tonnes of steel billets per year.

 The uniqueness of the Hamburg plant lies in its manufacture of sponge iron in its own direct reduction plant; it has an annual capacity of around 600,000 tonnes. This sponge iron can be used in the electric arc furnace as an alternative to steel scrap. As a result, it is possible to produce grades of steel that have demanding specifications for low concentrations of impurities in the electric arc furnace; typically, these can only be produced in the blast furnace. On average, the fraction of sponge iron in the furnace input materials lies around 45%.



The further processing of the billets takes place in the adjacent wire rod mill. Reshaping to an average diameter between 5.5 and 16 mm takes place in 26 roll stands at a maximum rolling speed of 100 meters per second. The mill produces about 800,000 tonnes of wire rod per year. The remaining billets are processed by rolling mills elsewhere within the company.  As a result of its convenient location in Hamburg harbour with its own pier installation, the Hamburg steelworks can fall back on all three modes of transportation. Thus, efficient and cost-effective transportation is always available. For example, iron ore can be delivered directly by boat from overseas. A further plus for Hamburg is its great flexibility in production planning. Even small customer orders can be filled within the shortest time.





By constantly optimising its facilities, the Hamburg plant is one of the most energy-efficient sites within the ArcelorMittal Group. By introducing natural gas in the reduction facility and electricity as the main source of energy in the steelworks, the specific CO2 emissions produced by processing are about half of those produced by conventional methods, where coke is used as the means of reduction.
