Abstract
An online tool based on computational fluid dynamics modelling was developed, validated and applied to Colakoglu Metallurji 2-strands slab caster to monitor and manage steel intermixing in tundish at ladle change. The tool allows to reduce the length of the slabs with intermixed steel. Different tundish layout and operating conditions are accounted for as slab size, presence of flow modifiers in tundish, tundish refill time, casting speed (also different from strand to strand), steel grade. The tool was developed by CSM following the suggestions and needs of Colakoglu Metallurji, who provided to a successful validation of such tool, both with slab sampling and support for installation and testing. As a result, the tool has been integrated into the Colakoglu CC2 control system and is currently used offline for optimizing a priori mixed grade production scheduling, and online for slab cutting optimization in order to reduce the downgraded product amount.
期刊介绍：
Matériaux & Techniques informs you, through high-quality and peer-reviewed research papers on research and progress in the domain of materials: physical-chemical characterization, implementation, resistance of materials in their environment (properties of use, modelling)... The journal concerns all materials, metals and alloys, nanotechnology, plastics, elastomers, composite materials, glass or ceramics. This journal for materials scientists, chemists, physicists, ceramicists, engineers, metallurgists and students provides 6 issues per year plus a special issue. Each issue, in addition to scientific articles on specialized topics, also contains selected technical news (conference announcements, new products etc.).
