Peiner Traeger, Germany, orders EAF mill
Jun 1, 2008
Peiner Traeger GmbH, Peine, Germany, a company of the Salzgitter Group, has awarded SMS Demag, Germany, a contract for the supply of an electric arc furnace meltshop and for the revamp of a continuous beam-blank caster to a combined slab/beam-blank caster. Facing the job of meeting stricter steel quality requirements, the new facilities will almost double the current annual production of around 1 million t of steel.
SMS Demag's supply includes a 125-t electric arc furnace with additives supply system plus two 125-t ladle furnaces. Concast AG, Switzerland has won the contract for the supply of a 125-t twin-tank vacuum degassing station. The use of the secondary metallurgy facilities makes it possible to produce advanced steel grades. The electric arc furnace therefore covers a wide range of products from high-quality steels to structural steels.
The electric arc furnac is optimized for the highly efficient use of electric power and includes future-oriented burner and oxygen injector technique. The metallurgical process model (Furnace Energy Optimization System) controls the
furnace process to ensure high productivity at low production cost.
Also included in the supply is the revamp of the two-strand beamblank caster to form a combined unit for casting steel slabs and alternately beam blanks. To this end, a revamping concept featuring short change times and high production speeds was developed. The two-strand combined continuous caster is rated for producing 250 mm thick slabs ranging in width between 800 and 1,100 mm as well as for beam blanks with dimensions of 1,150 x 490 x 130 mm.
Continuous caster no. 2 of Peiner Träger GmbH will thus become Germany's first combined caster for the production of beam blanks and slabs.
SMS Demag will supply the complete electrical equipment and automation system including process models (level 2). Commissioning of the new equipment is scheduled for early 2010.
Peine is the home of the world-famous Peine beams and produces a variety of other sectional steel types such as the European beam, piling sections and special sections. As part of its ambitious investment program, Peiner Träger GmbH had already in November 2007 ordered a new reversing tandem mill from SMS Meer, which will start operating in the summer of 2009.
No increase in the production of beams is planned, rather the higher steelmaking capacity will substitute bought-out quantities and supply slabs to the company's sister company Hoesch Spundwand in Dortmund. As the second furnace is commissioned, Peiner Traeger GmbH will become independent of the supply of material from external sources.
An SMS Demag-supplied electric steelmaking plant has been in operation in Peine since as long ago as 1996. It successfully uses a direct-current electric arc furnace with downstream ladle furnace.
