The submeniscus velocity has a big influence on the surface quality of slabs. Slabs casted with a low casting speed result in a low submeniscus velocity and suffer more from Al-inclusions, while slabs casted with a higher casting speed have a higher submeniscus velocity and suffer more from mould powder inclusions. If the submeniscus velocity can be controlled, the amount of slivers has to be reduced. ArcelorMittal Ghent decided to install an ElectroMagnetic Actuator (EMA) to control this submeniscus velocity. This topic shows what the impact of the EMA can be on slivers.
Key words: Continuous Casting / mould / fluid flows / electromagnetic actuator / slivers defects
