Siemens to Supply Three Two-Strand Slab Casters for Installation at Hyundai Steel Company, Dangjin Works, Korea


Linz, Jul 16, 2007, Siemens Metals Technologies received an order from Rotem, a company of the Hyundai Motor Group, for the supply of three 2-strand slab casters for the new integrated iron and steel works project of the Korean steel producer Hyundai Steel Company. The three casters will be installed at the steel producer’s Dangjin Works and are scheduled for start-up in late 2009. The contract value for Siemens is a two-digit million euro figure.

Hyundai Steel Company is Korea’s largest electric steel producer and the second largest electric steel producer in the world. At three production sites in the Republic of Korea the company currently produces a total of approximately eleven million tons of steel per year comprising carbon steel products, including reinforcing bars, angles, channels, wide-flange beams, rails, coils and sheets, and stainless steel products, including cold-rolled sheets and coils. The steel output will be expanded by approximately seven million tons at the company’s Dangjin factory site, located south of Seoul in the northwestern part of the Republic of Korea, where a new steel works is currently being built.

Siemens will supply its continuous casting technology and the related engineering and key components for three 2-strand slab casters which will be installed at the Dangjin plant site. These will have a combined annual casting capacity of 8.4 million tons of steel. The slabs will be cast in thicknesses of 225 and 250 mm and at widths ranging from 800–2,200 mm. The cast steel grades will include ultra-low-carbon to high-carbon steels as well as micro-alloyed steels. These will be rolled to coils which will be primarily used in the automotive industry of the Hyundai Motor Group and also in the household appliance industry. Steel which will be rolled to plates will be used in shipbuilding.

In order to ensure reliable casting operations, a high degree the operational flexibility and the production of high-quality slabs, the casters will be equipped with state-of-the-art mechanical equipment and technological packages. These includes DynaWidth (online mold-width adjustments for fast slab-width changes), MoldExpert (for online automatic breakout prediction and strand-shell friction monitoring), LevCon mold-level control, DynaFlex mold oscillation (for flexible adjustment of the oscillation stroke, frequency and wave-pattern parameters), SmartSegments with DynaGap SoftReduction (a fully automatic roll-gap-control system allowing dynamic soft reduction to minimized centerline segregation and thus to significantly improve internal strand quality), I-STAR Rollers (intermediately supported strand-guide rollers for improved strand-shell support and product quality) and the Level 2 Dynacs secondary-cooling system. The project also foresees advisory assistance during slab-caster manufacturing, construction, start-up and commissioning.

This was the first time in the history of the Siemens Group that an order was received for the supply of three large-sized slab casters in a single project contract.
