Laser-Ultrasound-Based Grain Size Gauge for the Hot Strip Mill

Laser-Ultrasound-Based Grain Size Gauge for the Hot Strip Mill

The paper summarizes the creation of a robust online grain size gauge for a hot strip mill. A method and algorithm for calculating the grain size from the measured ultrasonic attenuation is presented. This new method is self-calibrating, does not rely on a geometrical reference sample and can cope w...
