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 ?”

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 ?

How your MeltCup and QuickCup %C combustion analysis compare?

20161104_104622Wherever you live on our beautiful planet, welcome to SF blog hosted from Québec City! Today’s article shares preliminary results from a series of tests SF is conducting to understand performance of different thermal analysis cups for iron chemistry (with tellurium). The goal consists in investigating if there are differences between MeltCup and QuickCup that could influence your repeatability in %Carbon thermal analysis.  Continue reading “How your MeltCup and QuickCup %C combustion analysis compare?”

Download SF thermal analysis presentation at Vancouver AFSbc and read SF news

thermal analysis SF AFSbc 2016Have 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.

What is shrinkage casting defects ?

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.

Were you at the University Laval event on the physics of Thermal Analysis?

Équipe MetSoc- Sparkman et SFLast 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?”

Aluminum and Iron Microstructure by Thermal Analysis published by AFS

nod pass shrink failDid 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?
