Abstract
A strip thickness control method in a twin roll strip casting device having a fixed roll and a horizontally movable roll, the method including the steps of: measuring a movement value Gj(.theta.) of journals of the fixed and movable rolls and a movement value Gg(.theta.+.pi.) of barrels of the rolls; predicting a movement value Mfcr(.theta.) of a roll nip of the fixed roll and a movement value Mmer(.theta.) of a roll nip of the movable roll from the movement values Gj(.theta.) and Gg(.theta.+.pi.); calculating a difference value between the movement values Mfcr(.theta.) and Mmcr(.theta.) to obtain an amount of variation Mdiff(.theta.) of a gap between the fixed and movable rolls; and controlling thickness of a strip to minimize the amount of variation Mdiff(.theta.) of the gap between the rolls.
