<p>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(υ) of journals of the fixed and movable rolls and a movement value Gg(υ + π) of barrels of the rolls; predicting a movement value Mfcr(υ) of a roll nip of the fixed roll and a movement value Mmer (υ) of a roll nip of the movable roll from the movement values Gj(υ) and Gg(υ + π); calculating a difference value between the movement values Mfcr(υ) and Mmcr(υ) to obtain an amount of variation Mdiff(υ) of a gap between the fixed and movable rolls; and controlling thickness of a strip to minimize the amount of variation Mdiff(υ) of the gap between the rolls.</p> |
