Quantitative Analysis of Inclusions in Aluminum

Abstract

Three inclusion detection methods: image analysis, colorimetry and flux rinsing were compared aiming at the removal of solid oxide inclusions in molen aluminum in this paper. The testing results obtained from the comparative experiments indicate that the content of inclusions in aluminum can be detected quantitatively and quickly using the three methods. Image analysis is more intuitionistic, but testing value is a little larger; colorimetriy and flux rinsing method are of high accuracy, but testing values are estimated to be a little lower.
