Patent ID: 8713979

Claim:
A method for the operation of a coiling device used for coiling or uncoiling a metallic strip, which has at least one coiler and a control system for the coiler, the method comprising: a) measuring or calculating a current microstructure property of the strip by model calculation in real time during the coiling or uncoiling of the strip, b) determining a setpoint torque value by the control system in real time based at least in part on the measured or calculated current microstructure property of the strip, and c) adjusting at least one operational parameter of the coiler by the control system in real time based at least in part on the determined setpoint torque value, such that the at least one operational parameter of the coiler is adjusted in real time during the coiling or uncoiling of the strip based at least on the current microstructure property of the strip determined in real time during the coiling or uncoiling of the strip.
