Abstract
PURPOSE:To correct the offset of relative position of the web and the flange of the shape steel while continuing the rolling work, by installing the shape reforming mills before and behind the universal mill, and by making the ratio between the depth from the web-forming face of the roll to the flange-tip-reducing part and said depth after the rolling work different between above-mentioned two shape reforming mills. CONSTITUTION:In the universal roughing mill 24, a couple of horizontal rolls 10 and a couple of vertical rolls 12 perform the universal rolling pass for the shape steel by respectively forming the web 14 and the flange 16; whereas, the shape reforming mills 22, 26 apply the rolling work to the tips of the flange 16. In this case, if the relative position of the web 14 against the flange 16 to be detected on the run-out side of the roughing mill 24 comes out of the aimed value, the mill 22 adjusts the gap of upper and lower rolls 32, 36 so as to make the web-forming face 38 of the lower roll 34 and the flange-tip-reducing faces 36A, 36B of the roll 32 touch the rolled material. Besides, the relative position of the web 14 against the flange 16 is corrected by a proper amount. If the web 14 is offsetting to upside, it is corrected similarly by the shape reforming mill 28.
