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? Continue reading “Thermal analysis for aluminum and bifilm oxide code”
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 ?
Have you ever been there? Beautiful mountains, hikes, great kayaking… Vancouver area is a true natural wonder! Still, it was all about castings at the AFS Northwest regional congress last week. In this context, SF happily accepted the invitation and traveled 4,800km to give a lecture on thermal analysis for aluminum, iron and steel foundries and discuss why casting simulation goes hand-in-hand with thermal analysis for more profits.
How do you correct your melt in order to control stability ? What is shrinkage casting defects potential in the melt ? In this article, we’re not referring to gating design, casting geometry or casting procedures. Today, let’s discuss the metallurgical shrinkage tendency of the melt itself. David Sparkman at MeltLab presented this theory at the Ductile Iron Society last October 2015.
Last thursday January 28th, MetSoc student chapter at University Laval hosted this memorable beer and pizza event on the physics of thermal analysis, which was lectured by David Sparkman ( MeltLab). Can you tell what the gentleman on the left is holding on the photo? No, it’s not a beer funnel. Continue reading “Were you at the University Laval event on the physics of Thermal Analysis?”
Did you know how aluminum and iron microstructure by thermal analysis can be predicted by the new MetlLab technology ? Indeed, since 1980 MeltLab adds value to aluminium, bronze steel and more exotic metal castings. Here’s the 2011 AFS paper by David Sparkman. In 2016, why not use the best tool to measure and correct your melt for consistent castings? Continue reading “Aluminum and Iron Microstructure by Thermal Analysis published by AFS”
In 2021, click here to use SF Thermal Analysis to measure recaleascence. Do you know what is recalescence on a cooling curve ? How easy it is for your foundry to become more profitable in 2016 by measuring recalescence before pouring your castings ? Continue reading “What is recalescence and why you should care ?”
What really is recalescence and how do you control it for your castings ? On an other line of thought, how do you live bribery in your industry ? Here is just some of what you get in the free MeltLab newsletter, always sharing thoughtful insights and original topics to improve foundry understanding. We are subscribed, are you ?
