METHOD FOR CONTROLLING WIDTH CAMBER IN TEMPER ROLLING

摘要

PURPOSE:To control rolling so that a camber in the width direction in temper rolling is eliminated, by measuring the chamber in the width direction of a material to be rolled at the outlet side of a skin pass roll, and moving vertically an anti-cross brake roll in conformity with a controlling extent obtained from the calculation modified in relation to the thickness of material. CONSTITUTION:A signal of camber detected during rolling at the outlet side of a skin pass roll 2 of a temper rolling installation by a width camber detector 3 is converted by a converter 6 to input the converted signal to an arithmetic device 7 to which the informations relative to sheet thickness is previously inputted. A calculation to be modified by the sheet thickness for the purpose of moving an anti-cross brake roll 4 up and down is performed by the device 7 to output the result to an amplifier 8. The amplifier 8 outputs a signal to a driving device 5 to move the roll 4 up and down thereby controlling the camber in the width direction of a material 1 to be rolled. The variation in product qualities due to the difference in operator's skill is restrained by this controlling method.
