ArcelorMittal Hamburg: New walking beam furnace
by David Fleschen
More flexibility for the customers, better competitiveness for the customer Company: With the strategic investment in the new walking beam furnace ArcelorMittal secures the future of its production site in the Port of Hamburg. In addition to those in demand on the market ArcelorMittal achieves higher bundle weights of wire products with the investment of more than 15 Million euros also increases in energy efficiency and CO2 balance. The specific gas consumption is reduced by about 0.1 gigajoule per ton of wire rod, giving a saving potential of 19,000 Megawatt hours of natural gas per year. The lower CO2 emissions are also positive: with
The new kiln can be reduced by 3,800 tonnes or around seven percent a year. After three years of construction, the new kiln, consisting of more than 3,000 individual parts, was completed was put together, now in operation. The walking beam furnace has a fully automatic control logic of the combustion system, with the efficiency can be significantly increased. In addition, ArcelorMittal can use the larger oven Production of wire coils with a weight of two tons. For customers it is
higher bundle weight a clear advantage, since so the set-up times in the further processing of the wire too high quality products such as nails, screws, springs or wire ropes can be lowered.
The higher weight is achieved by the new walking beam furnace in the production process Wire primary products, so-called billets, up to a length of 16.5 meters (previously 13 meters) reheated before being rolled into wire. In the medium term, the expansion is to 2.5 tons bund weight planned. Another positive effect of the new furnace is that in the future ArcelorMittal will use the furnace waste heat for the Supplying almost CO2-free district heating to Hamburg's district heating network and so on an environmentally friendly energy supply for the city. More than 2,500 households in Hamburg could be supplied solely via the furnace waste heat, which saves over 15,000 tonnes of CO2 per year.
Dr. Uwe Braun, CEO of ArcelorMittal Hamburg, comments: "With such a large construction project many companies, internal bodies and authorities must
work together and exchange ideas - that worked perfectly. With the new Hubbalkenofen we make another contribution to sustainable and future-oriented
press release Steel production - that also comes in the use of industrial waste heat for the hamburger District heating network expressed. At the same time we secure with the higher coil weights of the coils more efficient processing options for our customers. "
Michael Westhagemann, Economics Senator of the Free and Hanseatic City of Hamburg: "A strong industry is not just for economic growth and social progress at the site Hamburg indispensable, it also sets worldwide standards in the development of environmental and climate-friendly products and production processes that are used by other regions can. The factory management of ArcelorMittal has never rested on their successes, but on their own
always oriented to the future. Worldwide trends and new challenges have come from her successfully implemented and put into practice with innovative technologies. "
Jens Kerstan, Senator for Environment and Energy of the Free and Hanseatic City of Hamburg: "In the basic industry, it is now self-evident, even from tangible economic reasons to focus on sustainability, climate protection and energy saving. Environmental policy is today innovative innovation policy is also evident in the state-of-the-art steelworks in Hamburg. From the common goal for climate protection and efficiency in energy and resources is in the past years ago a good cooperation in our networks with the industry has grown. We're glad, that ArcelorMittal in Hamburg continues to invest in its production and also in the district heating concept will play an innovative role. We understand that as a clear commitment to the location of Hamburg. The integration into the heat supply is also a step for long-term predictability and so that the location of the plant. "
