Study of Sheeting Behavior During Continuous Casting of Medium-Carbon Steels in a Thin-Slab Caster

Sheeting is a phenomenon observed in continuous casting that leads to large deviations in heat flux. Such large deviations can lead to a loss of lubrication, leading to sticker breakouts and other quality issues. Ozgu et al. postulated that sheeting was attributed to cracking of solid flux layer which eventually falls out, leaving behind a thin layer between the slab and the mold. Similar behavior was noted when casting medium-carbon steel grades (0.2-0.25%C) on a thin-slab caster. This paper investigates the influence of various operational conditions and mold powder chemistries on sheeting.
