An ultrasonic liquid steel inclusion monitor: Measurement principles and probe design

Abstract

This paper describes the application of ultrasonic scattering technologies for the development of a disposable ultrasonic probe measurement system that has the potential to (i) give size distributions for non-metallic inclusions in liquid steel and (ii) analyse relatively large volumes of liquid steel. This research demonstrates how it is possible to use the geometric condition of a dilute solution to identify a novel ultrasonic method by which l-100μm diameter particles can be both detected and sized. © 2009 American Institute of Physics.
