ThyssenKrupp Steel Europe has contracted SMS Siemag, Germany, to revamp the No 1 continuous caster at the Duisburg-Beeckerwerth works in Germany. The revamp will be carried out in 2014 during a planned shutdown period.

The aim of the planned revamp of the two-strand bow-type caster is to improve the slab quality and extend the product portfolio. The caster will be rated to produce slabs that are between 1000 and 2150mm wide and 257mm thick.

The plant will be equipped with an air-mist cooling system with adjustable, width-dependent breakdown of the cooling zones (ten control circuits per segment). After the revamp, casting will be effected dry, starting with segment nine. It is also planned to increase the strand length (segments 14 and 15).

SMS Siemag’s scope of supply comprises the delivery of all mechanical components as well as the entire X-Pact® electrical and automation package (extension of the 5-kV plant, drive technology, level 0, the entire process control system, the technological functions, level 1, and the process models, level 2). This also includes a new ladle turret (S-type) and an 80t-tundish as well as a tundish car with hydraulic lifting mechanism. A curved mould with Delta Speed narrow-face adjustment for high adjusting speeds during casting will be fitted. In addition, a five-row breakout prediction system with longitudinal facial crack detection as well as the hydraulic mould oscillator will be provided. The strand guiding system with hydraulic segment adjustment and dynamic soft reduction, a dynamic solidification model (Dynamic Solidification Control), the slab removal system as well as the entire hydraulic system and utility services will also be supplied by SMS Siemag.

In future, the dimensions of the continuous caster segments will be taken with the aid of a laser tracker and the measuring system developed by SMS Siemag.

Training is also included as well as the supervision of installation and commissioning.
