NEW ENGINEERING CONCEPTS FOR IMPROVEMENT OF SURFACE QUALITY
- Cosmo Di Cecca (Feralpi Siderurgica S.p.A.)
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...
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...
