DEVICE AND METHOD FOR MANUFACTURING UNEQUAL LEG AND UNEQUAL THICKNESS ANGLE STEEL

摘要

PROBLEM TO BE SOLVED: To suppress occurrence of a bend and a twist on unequal leg and unequal thickness angle steel.;SOLUTION: In this rolling mill outlet side guide 20, the motion in the ±Y direction of an unequal leg and unequal thickness angle steel 10 is restricted by side guides 21, 22 and side rollers 23, 24. Further, the motion of the downward direction (-Z direction) of the unequal leg and unequal thickness angle steel 10, which is produced by restricting the motion in the ±Y direction, is restricted by a table roller and the like. Further, the motion in the upward direction (+Z direction) of the unequal leg and unequal thickness angle steel 10, which is produced by restricting the motion in the ±Y direction, is restricted by a press roller 27. Consequently, occurrence of a bend and a twist on the unequal leg and unequal thickness angle steel 10 just after rolling is suppressed and the unequal leg and thickness angle steel 10 can be stably guided to a next groove and bitten therein.;COPYRIGHT: (C)2013,JPO&INPIT
