<p><P>PROBLEM TO BE SOLVED: To provide a buckling prevention method of a hot slab width press capable of preventing buckling of a hot slab and stably reducing the width in the width reduction of the hot slab by a width press device. <P>SOLUTION: When intermittently performing width reduction of the hot slab 10 by the width press device provided with a buckling restriction roll 12a on the slab upper face side and a buckling restriction roll 12b on the slab lower face side, the height positions of the buckling prevention rolls 12a, 12b are adjusted according to the predicted value of the board thickness increase amount of the tip end part 10a and the regular part 10b of the hot slab by width reduction. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
