Abstract

PURPOSE: To reduce the cracking of a slab by acting compressive force in its lengthwise direction near at least the horizontal leveling area and applying drawing force in the width direction near the horizontal leveling point in the curved type continuous casting.
CONSTITUTION: Horizontal drive rolls 10 of a speed nearly coinciding with the casting speed are provided in front of the portion near the horizontal leveling point of e.g. a slab 9 having unfrozen portions and brake rolls 11 of a speed slower than the casting speed are provided behind the portion near the horizontal leveling point, to apply compressive action in the lengthwise direction to the slab between these rolls. In addition, the drawing force in the width direction is applied to the slab by three pairs of broadside vertical rolls 12 near the horizontal leveling point. The vertical rolls 12a, 12b are drive rolls which are the same in speed as the horizontal drive rolls and the vertical rolls 12c are brake rolls of a low speed which apply drawing force dividedly at plural positions. The leveling strain with low-head casting is relieved by the synergistic effect of the compressive action in the lengthwise direction of the horizontal rolls 10, 11 and the lateral screw-down action and compressive action in the width direction of the vertical rolls 12.
