ABSTRACT:
An edging mill for section rolling has a pair of horizontal rolls, each horizontal roll including a pair of axially spaced horizontal roll segments supported by driven horizontal roll shafts. Eccentric rings are disposed between the two horizontal roll segments making up each horizontal roll and are rotatably mounted on the horizontal roll shaft. The eccentric rings are eccentric to the horizontal rolls. Web-restraining ring rolls each comprise a pair of web-restraining roll segments rotatably fitted over the periphery of the eccentric rings concentrically thereto. A web-restraining ring roll positioning device rotates the eccentric rings. While the horizontal rolls roll the flange edges of the section, the web-restraining ring rolls hold the web of the section therebetween. The position of the web-restraining ring rolls with respect to the horizontal rolls changes with the rotating angle of the eccentric rings. The position of the web-restraining ring rolls is adjusted according to the flange thickness of the section.
