The steel plant belonging to the international technology and capital goods group voestalpine in Linz where the company is headquartered is already one of the most modern of its kind in the world. Now, in addition to a series of other parallel projects, the Group is investing over EUR 100 million in a new continuous caster at this site which will produce over 1.2 million tons of high quality steel slabs annually. The largest of the four Group divisions, the Steel Division, is again raising the quality of steel grades with the most stringent surface requirements as a result of this technological development.

Yesterday saw the ground-breaking ceremony for the new Continuous Caster 8 (CC8) at the voestalpine plant site in Linz. From mid-2017 onwards the new facility will annually cast 1.2 million tons of steel in slabs – the pre-materials for high quality steel products including steel strip for automotive components. This strategically important investment at the Linz production site amounts to over EUR 100 million and will create 42 jobs. Construction is estimated to require 24 months.

With a capacity of 1.2 million tons per year, the new CC8 will take over around a fifth of all steel slab production on site and replace Continuous Caster 3 (CC3).

As its name suggests, the continuous caster casts molten steel into a single strand in an ongoing process. After solidifying, the steel is cut into individual blocks, so-called slabs. The slabs are then rolled into high quality steel strips in the hot and cold rolling mill. The CC8 is designed to cast a single strand, for slabs with a thickness of up to 22.5 cm and a width of between 80 to 182 cm. Future adaptations will permit casting of slabs with a thickness of up to 28.5 cm. The slabs themselves are primarily high strength steel grades, ultra-low carbon steels with the most stringent of surface requirements for the automotive industry, and electric steel grades.

Construction of the Continuous Caster 8 belonging to the Steel Division, together with the recent ground-breaking ceremony for the Metal Forming Division’s second blank production facility, play an important role in securing the site at Linz over the long term. voestalpine currently employs a staff of 11,500 in Upper Austria which generated total revenue of around EUR 4 billion during the business year 2014/15. The Group has invested around EUR 3.3 billion in this Austrian province in the past ten years alone.
