Keyword: infrared thermal imager; ingot defects; mold’s surface; metallographic method; oxygen content analysis;
Abstract: In this article the temperature distribution of mold’s surface in solidification process of the ingot was observed and measured by infrared thermal imager directly. We compared and analyzed the trend and regularity of the temperature change with time in several key points. And the possible ingot defects were speculated in correspondence. The microstructure of ingot was analyzed by the metallographic method and oxygen content analysis. The result was confirmed according to the statistical data. It is proved that judging ingot defects by infrared thermal imager is feasible to some extent.
