Abstract

This method for manufacturing a steel H-beam comprises a rough rolling step, an intermediate rolling step, and a finishing rolling step. A rolling machine that performs the rough rolling step is provided with a plurality of grooves that shape a to-be-rolled material. The plurality of grooves include: one or a plurality of dividing grooves in which protrusions are formed that cause a divided part to be formed in an end portion of the to-be-rolled material by forming a cut in a direction perpendicular to the width direction of the to-be-rolled material; and a plurality of bending grooves in which protrusions are formed that contact the cut and sequentially bend the divided part formed at the dividing groove. The protrusion formed in a final dividing groove among the dividing grooves is constituted by a tapered tip part having a prescribed tip angle and a base part located at the base of the tip part and having a tapered shape with a gentler slope than the tip part.
