The quality of molten metal is of growing importance and with this also the ability to measure quality. LiMCA is a unique, well-established tool for monitoring inclusions in molten aluminum. However, the cost of LiMCA or lack of a launder are reasons why some are not controlling the quality by LiMCA. As an alternative, the Straube-Pfeiffer vacuum test has been further developed to a quantitative method for metal quality resulting in a bi-film index.
In this paper industrial remelting campaigns are presented where both bi-film index and LiMCA measurements were preformed. They measure the quality out of the furncace with varying holding time and scrap additions. The correlation between LiMCA and bi-film index is presented, showing that the bi-film index is a useful tool for quantitative analysis of aluminum quality.
