Thermal analysis, spectrometry and bi-film code for your liquid aluminum quality ?

You know that testing for mechanical properties or X-Ray won’t avoid scrapping your aluminum casting. We can pray but it’s too little too late : we need to work with the liquid metal, not the solid casting. And ASTM standards won’t help us much on reaching your energy efficiency and low scrap rate objectives. Best practices and data will. This article offers a sneak peak of the recent  MODERN CASTING  survey on melt control practices ( figure 1 ). Then a word on  thermal analysis for liquid aluminum quality control and simply, why spectrographic analysis is not enough to make good money out of your melt. In the end, you’re getting your foundry more and more into John Campbell’s bi-film code , right? Continue reading “Thermal analysis, spectrometry and bi-film code for your liquid aluminum quality ?”
