【発明の名称】圧延機における帯体の平面性の測定方法および装置
Document Type and Number:
Japanese Patent JPH0697167
Kind Code:
B2
Abstract:
A process and apparatus for on-line measurement of unflatness of hot or cold rolled strip products, wherein the longidudinal bending of a shape roll over which the strip passes provides a measure of the unflatness of the strip. Actual values of force, displacement or bending moment near the ends of the shape roll may be compared to theoretically predicted values for a flat product and for product having various out-of-flatness conditions. Preferably, the shape roll is supported at its ends by two pairs of supports, and the measurements at the supports are used in determining roll bending and thence strip unflatness. Other conditions such as off-center strip and asymmetric operation of the rolling mill may also be determined from the measurement.
