CA 2378663

The invention concerns a method for displaying, measuring the size and individually counting inclusions suspended in a moving liquid metal (7), using a sensor comprising at least means (1) for emitting successive ultrasonic beams inside said molten metal, at least means (2) for receiving echoes reverberated by said inclusions, and their accessories. The invention is characterised in that it comprises a step which consists in calibrating the sensor response, said step using at least a calibrating echo sounder (10) of known dimension of reverberated echoes, a step for displaying, such a B-scan, and an image analysing step to count and measure the diameter of the inclusions.

Procédé de visualisation, de mesure de la taille et de comptage individuels des inclusions en suspension dans un métal liquide en mouvement (7), à l'aide d'un capteur comprenant au moins un moyen (1) pour émettre une succession de tirs de faisceaux d'ultrasons au sein dudit métal liquide, au moins un moyen (2) pour recevoir les échos réfléchis par lesdites inclusions, et leurs accessoires, caractérisé en ce qu'il comporte une étape d'étalonnage de la réponse du capteur, ladite étape mettant en oeuvre au moins un réflecteur étalon (10) de dimension connue stable en cours du temps, des étapes successives d'acquisition et de traitement des échos réfléchis, une étape de visualisation, par exemple de type B scan, et une étape d'analyse d'image pour compter et mesurer le diamètre des inclusions.
