Abstract

PURPOSE:To manufacture the high accurate channel with parallel opposite flange faces, by reform rolling the channel just delivered from the finishing pass, by giving the inward bending to both flanges while reforming the channel to the web with the freely rotatable roller which makes the rolling contact against the web between both flanges. CONSTITUTION:The parallel flange channel 2, being rolled with the finishing caliber mills 1, 1 is guided along the rolling line L by the delivery guide 3; next, the channel 2 is subjected to the reform rolling to be performed by the freely rotatable rollers 4, 5, 6, 7. Rollers 4, 5 carry out the reform rolling by inward bending the flanges 2F. Hereupon, the flanges 2F are bent inward so far as the inclination of the rolling face 9 over the parallel condition of flanges 2F. The rolling faces 12, 13 of rollers 6, 7 being born respectively by the shafts 10, 11, perpendicular to the shaft 8, press the inside face A2 and the outside face A3 of the web 2W to support the web 2W against the rolling force of rollers 4, 5, and also, straighten the bend of the web 2W. The flanges 2F, 2F are made parallel through the reform rolling with rollers 4, 5.
