Abstract
A facility cost and a remodeling cost can be reduced, and further, a steel sheet pile product with high dimensional accuracy is produced by suppressing occurrence of warpage of a material to be rolled during bending. There is provided a bending device which produces a steel sheet pile by performing bending on a material to be rolled after being subjected to rough rolling, intermediate rolling, and finish rolling in a hot state, in a direction of increasing a cross sectional height of the material to be rolled, the bending device including: a forming stand including a forming caliber configured by an upper caliber roll and a lower caliber roll; and a drive unit driving either the upper caliber roll or the lower caliber roll.
