Abstract

PURPOSE: To straighten the defective shape at top and bottom portions of the steel sheet pile, being generated during the straightening pass, by making larger the roller pitch of the first half roller group than that of the latter half roller group, at the method for giving a heavy reduction with the first half roller group and a light reduction with the latter half roller group in the roller leveler.
CONSTITUTION: In the straightening rollers 11W19 of the roller leveler 1, a heavy reduction is given to the U-type steel sheet pile 2 with the first half roller group 11W 15. Further a light reduction is given with the latter half roller group 15W19. The roller pitch is set to the usual value at the first half roller group, and is set to a smaller value at the latter half roller group than that of the first half roller group. Hereby, the steel sheet pile 2 with the exception of its top and bottom portions is straightened at high efficiency at the first half roller group; hereupon, a great deformation is caused at top and bottom portions of the sheet pile 2; however, this deformation is straightened at the latter half roller group.
