<p>PURPOSE:To make a rolled stock a good shape without reduction of a rolling speed and to improve the yield by adjusting a thermal crown of a work roll in the axial direction and adjusting a bending force of an intermediate roll and of the work roll by changing shift amount of the intermediate roll. CONSTITUTION:A cooling condition (a flow rate, temp., and concentration) of a work roll 6 in the axial direction is changed using a model calculation and a thermal crown of the work roll 6 is adjusted for changing size of a plate stock 1 by a cold continuous rolling mill 5. Then, a shift amount of an intermediate roll 7 is changed to adjust a bending force of the roll 6 and of the roll 7. With the above procedures, a dimension of the stock 1 is made to be better smoothly without reduction of the rolling speed and reduction of the material yield and of the productivity is prevented.</p> |
