Abstract

PURPOSE:To form the smooth surface, and to improve the dimensional accuracy, by correcting shape of the part, unrestrained by the caliber, of the round bar product delivered from the caliber, using a pair of vertical guide rollers. CONSTITUTION:The vertical guide rollers 13, 13', are installed so as to be freely rotatably borne by the upper window frame and the lower window frame of the see- through window 12 of the side plates 11, 11', facing each other, of the exit guide 8. The caliber being formed by the upper roll 1 and the lower roll 2, and the caliber being formed by the vertical guide rollers 13, 13', are constituted into a circle centering at the pass line the same radius. The round bar product passes through the round finishing caliber, and is sent into this duplex reversing mill which then corrects the parts 4, 4', unrestrained by the caliber, of the round bar product with the vertical guide rollers 13, 13'. Accordingly, even if the over-fill or under-fill exist in these parts 4, 4', these shape defects are normalized and the product can be formed into the specified dimension.
