ABSTRACT:
For decreasing the width of a thin slab: a turning roll contacts the thin slab being conveyed at a certain contact angle to curve the thin slab; a tension applying device disposed in front and at the back of the turning roll, applys a tension to the thin slab forwardly and rearwardly in the direction of conveyance of the slab. Thus, the slab can be decreased in its width to a satisfactory section with no buckling loop forming portions for forming loops of the hot thin slab at the inlet and the outlet sides of the apparatus for decreasing the width of the thin slab absorb the intermittent proceeding of the hot thin slab in the direction of flow of the material. Thus, the continuous receipt and the delivery of the slab are made possible while the intermittent width decrease is performed, and the combination of the continuous casting equipment with the hot finish rolling equipment is materialized.
