ABSTRACT:
The eccentricity of a hollow billet is measured at the outlet of an inclined-roll rolling mill by launching an ultrasonic pulse into the billet from a laser of a measuring device and measuring the transit time of an echo pulse also utilizing a laser and an optical analyzer. The measuring device is moved, during travel of the hollow billet along a path from the rolling mill linearly into the direction of travel or angularly around the hollow billet to eliminate the effect of the internal helical formation of the eccentricity on the measurements. The wall thickness measurements are evaluated by a computer and subjected to Fourier analysis.
