Abstract

Continuous casting equipment includes a casting product reduction apparatus and a casting product drawing apparatus, the casting product reduction apparatus including a pair of casting product reduction rolls that sandwich and apply pressure to a casting product and being configured to apply reduction to the casting product, the casting product drawing apparatus being provided in a following stage of the casting product reduction apparatus and configured to sandwich and draw the casting product with a pair of casting product drawing rolls. At least one of the pair of casting product reduction rolls includes a large-diameter part that projects radially outward in an axial-direction center region and applies pressure to a width-direction center region of the casting product. The casting product that is subjected to reduction by the casting product reduction apparatus has a depressed part corresponding to the large-diameter part. At least one of the pair of casting product drawing rolls of the casting product drawing apparatus includes a depressed part supporting part that contacts with and supports the depressed part, and is driven by a driving mechanism. An axial-direction length Lof the depressed part supporting part and an axial-direction length Lof the large-diameter part of the casting product reduction roll satisfy 0.5×L≦L<L.
