<p>PURPOSE:To correct the distortion of sectional shape of a material to be rolled and to easily and safely make the adjustment possible by moving a pair of rolling rolls integrally in the direction of roll axis with respect pass line of the material to be rolled during rolling. CONSTITUTION:When a pair of the rolling rolls 20, 21 are integrally moved in the direction of roll axis, a drive shaft 54 is revolved with a revolving means 57 and a pair of turning shafts 27 are revolved in a different direction. Then, respective pairs of arms 29, 30, 31, 32 with which each of roll chock parts 25, 26 are clamped are integrally turned with the turning shafts 27. Consequently, a pair of the rolling rolls 20, 21 is moved in the axial direction through of roll chock parts 25, 26. In this way, the position of caliber of the rolling rolls 20, 21 can be adjusted on the pass line 6 even during rolling.</p> |
