Several slag rims and lubrication behaviours in slab casting
Phenomena that occur at the meniscus in the CC mould have a major effect on product quality. The mechanism of slag rim behaviour and flux infiltration are reported based on the results of industrial characterization and of fluid dynamics modelling of the effect of oscillation and shell velocity. Lubrication stability is not established as the slag film happens to be broken down and renewed several times during casting. A mechanism of slag infiltration is put forward and the main factors for oscillation marks formation are pointed out.
