Simulation of IMPOC system for online monitoring of steel mechanical properties
Résumé
The IMPOC system is a broadly applied device in steel industry for the online assessment of steel strip’s mechanical properties. It carries out non-destructive electromagnetic measurements that are very well correlated with properties like tensile strength and yield strength, for instance. The measurement is however not only sensitive to the electromagnetic properties of the steel strip under investigation, but it is also influenced by other factors, like the strip thickness, its speed variations, and the lift-off separating it from the IMPOC system. To mitigate those effects, some empirical compensation functions are introduced (in the case of strip speed in particular) as a postprocessing. The use of accurate modelling tools enables to better understand the various effects and allows the theoretical calculations of compensation coefficients.
