Dillinger Hüttenwerke Casts World’s Thickest Slabs after SMS Siemag Upgrade
11/29/2010 - Dillinger Hüttenwerke re-commissions its Continuous Caster No. 5 following a revamp and 450-mm enlargement in thickness by SMS Siemag. The vertical-type continuous caster, which was originally supplied by SMS Siemag in 1998, now produces the world's thickest slabs, with sizes from 230 to 450 mm gage and 1400 to 2200 mm width.
Aktien-Gesellschaft der Dillinger Hüttenwerke, Germany, recently re-commissioned its Continuous Caster No. 5 following a revamp and 450-mm enlargement in thickness. The revamp was supported by a comprehensive engineering package and new components from SMS Siemag.
The vertical-type continuous caster, which was originally supplied by SMS Siemag in 1998, now produces the world's thickest slabs, with sizes from 230 to 450 mm gage and 1400 to 2200 mm width.
SMS Siemag’s supply scope for the revamp comprised the expansion of the vertical-type continuous caster to a thickness of 450 mm, as well as reinforcement of the withdrawal and straightening units and supply of various spare parts. The supply scope also included the X-Pact® electrical and automation package, including planning and production for the package, as well as programming of the electrical equipment, installation, commissioning, training and supervision of trial operation.
As part of the caster’s revamp, automatic control equipment for the hydraulic mold oscillator was renewed, as were the hydraulic segment adjustment, hydraulic bending adjustment system, hydraulic adjustment system for the withdrawal and straightening units, and the load compensation control for the strand drive group.
“After twelve years of trouble-free production of high-quality 400-mm slabs, we felt that we had arrived at a favorable starting point for this further development,” said Dr. Norbert Bannenberg, Board Member Technical of AG der Dillinger Hüttenwerke. “Dillinger Hütte thereby emphasizes its leading position in the continuous casting of thick slabs as input material for the production of high-grade heavy plate."
In China, in 2005, SMS Siemag put into operation a continuous caster for the world's widest slab and now, also on a caster from SMS Siemag, the world's thickest slab has been produced.
SMS Siemag AG is a company of the SMS group, which is, under the roof of the holding SMS GmbH, a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry. It consists of the two Business Areas SMS Siemag and SMS Meer. In 2009, some 9000 employees worldwide generated a turnover of EUR 3.9 billion.
