Abstract

This H-section steel manufacturing method comprises: an edging rolling step of rolling and shaping a material to be rolled into a predetermined shape; a raised portion generating step of rolling a web portion by rotating the material to be rolled and forming a raised portion at the center of the web portion of the material to be rolled; an auxiliary edging rolling step of rotating again the material to be rolled that has been rolled through one or more passes in the raised portion generating step, and replacing the material to be rolled back into a final caliber for the edging rolling step to perform light reducing-down rolling; and a raised portion eliminating step of reducing down and eliminating the raised portion formed in the raised portion generating step. Upper and lower caliber rolls for performing the raised portion generating step are provided with, at the center in the roll body length of the upper and lower caliber rolls, a recess for forming the raised portion at the center of the web portion of the material to be rolled. The roll shape of the upper and lower caliber rolls is designed so as to not contact a flange portion tip of the material to be rolled. The two steps of the raised portion generating step and the auxiliary edging rolling step are performed successively once or a plurality of times. The raised portion eliminating step is implemented after the raised portion generating step and the auxiliary edging rolling step are performed.
