    • The invention is for ultrasonic testing using surface waves, and its object is to prevent false detection of primary cracks, to lower the level of structural noises from grain boundaries, and to improve the detectability in the ultrasonic testing. Concretely, in surface wave testing of hot rolling rolls, used is a surface wave probe 10 capable of transmitting and receiving a surface wave and provided with a piezoelectric element 10A, a resin wedge 10C disposed on the front surface of the piezoelectric element 10A and a damping block 10B disposed on the back surface thereof, and the surface wave probe 10 is driven to produce a short pulse having a pulse length of being at most 2.5 times the wavelength of the surface wave to be produced. In this, a coupling liquid medium is supplied to the probe 10 in accordance with the peripheral speed of the roll to be tested. Depending on the height of the reflected waves measured, the grinding allowance of the roll is determined, and the roll is ground according to the thus-determined grinding allowance. The roll may be tested while being partly ground, and the optimum grinding allowance of the roll may be determined.

    • PURPOSE: To eliminate strip breakage by meandering of a rolled stock and defect in shape and to prevent the deterioration of product quality and drop of productivity by reducing the difference of the coefficient of friction between upper and lower work rolls by grinding in the longitudinal direction in on-line roll griding. CONSTITUTION: By performing grinding while respectively moving grindstone devices 3a and 3b in the opposite direction to each other in the upper and lower work rolls 2a and 2b respectively, the respective ranges to be ground in the upper work roll 2a and lower work roll 2b are symmetrically arranged to the centers of the rolls in the operation side and the drive side. Thus, the coefficients of friction on the operation side and the drive side can be made equal and the meandering of the rolled stock 6, breakage by the meandering and defect in shape are prevented. The timing when the grinding is respectively started with the grindstone devices 3a and 3b are approximately same and, by equalizing the moving speeds of the grindstone devices 3a and 3b in the axial direction of the work roll, the difference of the coefficient of friction by grinding in the longitudinal direction of the roll is stably reduced.
