Edging mill for section rolling.

摘要

An edging mill for section rolling according to this invention comprises a pair of horizontal rolls (37), each horizontal roll comprising a pair of axially spaced horizontal roll segments (38) supported by driven horizontal roll shafts (29); eccentric rings (54) disposed between the two horizontal roll segments making up each horizontal roll and rotatably mounted on the horizontal roll shaft, the eccentric rings being eccentric to the horizontal rolls; web-restraining ring rolls (61) each of which comprises a pair of web-restraining roll segments (62) rotatably fitted over the periphery of the eccentric rings concentrically thereto; and a web-restraining ring roll positioning device (68) to rotate the eccentric rings. While the horizontal rolls (37) roll the flange edges of the section, the web-restraining ring rolls (61) hold the web of the section therebetween. The position of the web-restraining ring rolls (61) with respect to the horizontal rolls (37) changes with the rotating angle of the eccentric rings (54). The position of the web-restraining ring rolls (61) is adjusted according to the flange thickness of the section. <IMAGE>
