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.
