<p>PROBLEM TO BE SOLVED: To provide an efficient grinding method of a tapered work roll according to the rolling specifications of a stock to be rolled. SOLUTION: The starting position for roll taper before grinding is obtained and the allowable range of the starting position for roll taper corresponding to the conditions of the stock to be rolled is determined and the starting position is compared with the allowable range, only when the starting position for roll taper before grinding exceeds the upper limit value, both longitudinal ends of the roll and the central part thereof are ground and when the starting position does not exceed the upper limit, the both longitudinal ends are not ground, but only the central part is ground to set the starting position of roll taper after grinding within the allowable range.</p> |
