Abstract
PURPOSE: To obtain the casting of good quality free from occurrence of any internal crack by adding screw-down in the width direction at plural positions to a slab near the horizontal leveling point in the curved type continuous casting.
CONSTITUTION: The slab which is pulled in arc form and has unfrozen portions in the inside is screwed down by die rolls at plural positions near the horizontal leveling point. For example, the slab 9 is passed through float rolls 2, support rolls 3, guide rolls 4 and pinch rolls 8 from a mold 1 and is leveled by leveling rolls 5. Broadside reducing die rolls 10 are provided near this horizontal leveling point. Of the die rolls 10, the rolls 10a on the inlet side are made drive rolls to push in the slab and the rolls 10c on the exit side are made low-speed- or non-driven idle rolls to apply braking force. As a result of this, the slab 9 is relieved of leveling strain by the synergistic effect of the lateral screw-down action in the width direction and the compression action in the lengthwise direction, whereby the occurrence of slab cracking is effectively prevented and low-head casting is made possible.
