Abstract

In September 2011, one of the world’s most modern slab casters was commissioned at voestalpine Stahl GmbH steel plant LD Nr. 3 in Linz, Austria. The caster covers a wide range of thicknesses from 225 mm to 355 mm and widths from 740 mm to 2200 mm and is equipped with the latest state-of-the-art technology, e.g. Smart bender, width adjustable spray nozzles (3D Sprays) and the latest generation of process automation models, such as the further advanced secondary cooling system Dynacs 3D and DynaGap Soft Reduction®. These technological features have been implemented to achieve the highest quality slabs. Unique and the first time ever installed in a steel plant is the operation of two LiquiRob robots which completes all the dangerous work activities automatically and allows monitoring of casting process from the safety of the control room. An overview about this unique safety operation concept and selected operational results of this most modern casting machine are highlighted.
