CONTINUOUS CASTING MACHINE OF VERTICAL BENDING DIE PROVIDED WITH DEVICE FOR INSERTING UPWARD DUMMY BAR

摘要

PURPOSE:To provide a titled continuous casting machine which disconnects a billet and a dummy bar in the position where curving of the billet in a billet pass line starts and can take the dummy bar from the mid-way of the billet pass line by the constitution in which a dummy bar table is placed to face said position from the side of the billet pass line. CONSTITUTION:A dummy bar 14 placed on a dummy bar car 15 is run on a casting floor 11 and is positioned so as to be inserted into a mold 1 and guide rolls 2 by a feeder of the car 15. The dummy bar is drawn in the state of connecting the same to a billet by the driving rolls 2A of the rolls 2 at the same instant when casting is started. The top end of the bar 14 is guided in the curved rising part of a dummy bar stage 18 on a dummy bar table 9 and is transferred to a horizontal part. After the junction between the bar 14 and the billet 7 passes the lower roll of pinch rolls 3, the table 9 is pushed rightward via a bending roll 4 by a hydraulic cylinder 8 to disconnect the bar 14 from the billet 7. The bar 14 is then hooked to a hook 21 and is hoisted by a winch 12 until the bar is placed on the car 15 and is kept standing by.
