摘要

The quality of a cast product depends directly on the quality of the molten metal from which the product is cast. Techniques for determining melt quality often require the laboratory analysis of samples taken from the molten metal. In addition to reducing processing efficiency, delays associated with this laboratory analysis can lead to uncertainties because the melt conditions can change during holding at high temperatures. On-line monitoring of the melt quality provides more rapid feedback for improved process control. In this article, techniques for monitoring the important aspects of melt quality, specifically chemical composition, gas content, and inclusion content, are reviewed.
