Abstract (en)

The object of the invention is to provide a continuous casting method and a continuous casting machine for producing thin-slab cast strips stably. A continuous casting machine of a vertical bending type for casting thin-slab cast strips, wherein a liquid core reduction-roll segment 4 is provided so as to constitute rolls in the bending zone B below the mold 1. The liquid core reduction-roll segment 4 comprises a group of fixed rolls 8 disposed outside the guide roll radius being bent of a cast strip and a group of movable rolls 3 disposed inside the guide roll radius. The group of movable rolls 3 is supported by a tilting frame guide roll radius 7 with an oil-hydraulic cylinder 10 so that it is moved toward the group of fixed rolls 8 to roll the cast strip. <IMAGE>

A method of casting a thin-slab cast strip with a continuous casting machine of a vertical bending type. The method comprises bending the cast strip drawn out of a mould (1) in a bending zone with simultaneous liquid core reduction in an unsolidified state. The continuous casting apparatus comprises: (1) the liquid core reduction-roll segment (4) comprising a group of fixed rolls (8) disposed outside the guide roll radius bent of a cast strip and a group of movable rolls (3) positioned inside the guide roll radius; (2) the group of movable rolls is supported by a tilting frame guide roll radius (7) with a oil-hydraulic cylinder (10) which moves toward and away from the group of fixed rolls.
