You know that testing for leakage, mechanical properties or X-Ray won’t avoid suddenly scrapping your aluminum castings. We can pray but it’s too little too late : we need to work with liquid metal and mold control before casting, not just tests on 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 2016 MODERN CASTING survey on melt control practices ( figure 1 ). Then a word on thermal analysis for liquid aluminum quality control. 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 bifilm code , right?

16 oxide inclusion detection methods for aluminum melt cleanliness
Welcome to SF blog ! Today we look into Dr. Apelian’s team paper review published by the AFS in 2016 on oxide inclusion detection methods for aluminum melt cleanliness. Then, we open with R&D work in progress by SF for hydrogen and oxide bi-film related porosity control in aluminum melt using thermal analysis. Which method do you use ?
