<p>PROBLEM TO BE SOLVED: To provide a method manufacturing a plate-like metal product being low cost and efficient and free from camber, by controlling a shape ratio being a divided value with an average value of inlet- and outlet-sides plate thicknesses, an arc length between a stock and a roll. SOLUTION: In a rolling in which an absolute value of different roll-speeds ratio (VT-VB)/VF×100 (Here, VT is a peripheral speed of upper work roll, VB is a peripheral speed of lower work roll, VF is a peripheral speed of high speed side work roll.) is <=10% and a plate mill equipping roll system at least up and down is used, a reduction schedule is set up so that a range of shape ratioΓbeing a value dividing the arc length between the stock and the roll with the average value of the inlet- and outlet-sides thicknesses may become 1.6<Γ<2.0, and the plate-like metal product being low cost and efficient and free from camber is manufactured.</p> |
