Abstract

PURPOSE: To decrease the cracking of a slab by applying compressive force through light screw-down to the slab in its lengthwise direction near its horizontal leveling area and applying the screw-down in the width direction and the broadside screw- down restraining the top and bottom surfaces near the horizontal leveling point in the curved type continuous casting.
CONSTITUTION: For example, a slab 9 having unfrozen portions is lightly screwed down by horizontal drive rolls 10 of nearly the same speed as the casting speed in front of the horizontal leveling point and is given compressive action in its lengthwise direction by brake rolls 11 of a slower speed behind the horizontal leveling point. Also, the screw-down in the width direction and compressive force in the lengthwise direction within a range of the broadside screw-down are applied by die rolls 12 near the horizontal leveling point. The die rolls 12 are of a plurality consisting of drive rolls 12a, 12c and control rolls 12c. In order to prevent the occurrence of buckling in the slab 9, the horizontal rolls 14 restraining its top and bottom surfaces are provided. At this time, the die rolls 12 and horizontal rolls 14 are so disposed that the die axis of the former aligns to the horizontal axis of the horizontal rolls 14, to apply no screw-down to the horizontal rolls 14.
