One of the typical quality problems of near-net-shape products such as the beam blank is the appearance of surface and sub-surface cracks. The complex shape of the mould makes the casting of crack sensitive grades particularly challenging. This paper describes the process of modifying an existing beam blank section to improve its quality performance. It starts with the analysis carried out to...

5. Our Segments like it hot – how Smart Segment Engineering directly influences Slab Surface QualityDr Kerstin Baumgartner (Primetals Technologies Austria GmbH)13/03/2026, 11:05New engineering concepts for improvement of surface qualityOral Presentation
Continuous casting of slabs demands stringent control of thermal and mechanical conditions to ensure crack-free surfaces and dimensional accuracy. The rising concentration of tramp elements in steel, resulting from modern steelmaking practices, significantly increases susceptibility to hot cracking, particularly within the straightening zone. Maintaining temperatures above the second...

Casting 355 mm ultra thick slabs at voestalpine’s CC7 caster - designed for three casting thicknesses (225, 285, and 355 mm) and widths up to 2,200 mm, with a 10 m bow radius - pushes surface integrity and slab geometry control to their limits. This extreme section size range combined with the 10 m bow radius induces severe thermal gradients and mechanical stresses, which negatively affect...
