Abstract
A casting of metal strip by continuous casting in a twin roll caster is provied. In a twin roll caster, molten metal is introduced between a pair of counter-rotated horizontal casting rolls that are cooled so that metal shells solidify on the moving roll surfaces. The twin roll caster is capable of continuously producing cast strip from molten steel through a sequence of ladles positioned on a turret. In casting thin strip by twin roll caster, the crown of the casting surfaces of the casting rolls varies during a casting campaign. The crown of the casting surfaces of the casting rolls in turn determines the strip thickness profile.
