Abstract
A meandering amount detection method for a metal strip that detects a meandering amount of a metal strip traveling in a state of being overlapped in a plurality of stages at intervals, the meandering amount detection method includes: measuring a distance from a mounting position of a distance meter in a direction intersecting a width direction of a metal strip, using a plurality of distance meters provided side by side in the width direction of the metal strip on at least one side in a width direction of the metal strips overlapped in the plurality of stages; and detecting a stage of a metal strip in which meandering occurs and a meandering amount, using the mounting position of a distance meter and the measurement value.
Claims2
A meandering control method for a metal strip, comprising controlling meandering of the metal strip based on a meandering amount of the metal strip detected by measuring a distance from a mounting position of a distance meter in a direction intersecting a width direction of the metal strip, using a plurality of distance meters provided side by side in the width direction of the metal strip on at least one side in the width direction of the metal strip overlapped in a plurality of stages;
- and
- detecting a stage of the metal strip in which meandering occurs and a meandering amount, using the mounting position of the plurality of distance meters and a measurement value of a distance meter of the plurality meters.
