Daniel Coyle, MAGMA Foundry Tech- nologies, Inc. (Schaumburg, Illinois) This presentation will show two examples where casting simula- tion software was used to calculate manufacturing costs for many differ- ent gating system configurations and the lowest casting price was autono- mously realized.
Process Essentials of Combining Powder Metallurgical Inserts With Gray Iron (17-072) Lennart Elmquist, Swerea SWECAST AB (Jonkoping, Sweden) Multi-material components offer
the advantages of elevated local prop- erties with more economical sub- strates. In this work we have evaluated the process essentials of integrating powder metallurgical inserts in gray iron. In the discussion, the potential applications for the proposed technol- ogy will be presented.
3:15-4:15 p.m. Introduction and Experiences in SMARTT Degassing (17-012)
Brian Began, Foseco (Cleveland); Ronny Simon, Foseco GmbH (Borken, Germany) This presentation will discuss
hydrogen removal in cast alumi- num alloys, covering the variables, the measurement and a model for improving rotary degassing. It also discusses efforts to integrate a devel- oped rotary degassing model into a metal treatment station used at a production facility.
I Have Inclusions. Get Me the Cheapest and Best Flux for Cleaning My Melt—Is Tis the Best Driven Cost Saving Approach by a Foundry? (17-106) Rafael Gallo, Pyrotek Inc. (Aurora, Ohio) Te elimination of inclusion defects
requires proper collection and analysis of data. Attempting a corrective action without knowing exactly what the inclusion is may prove very expensive. Unfortunately, it is not uncommon practice to inaccurately identify an inclusion based on educated guesses, erroneously avoid paying for the cost
of properly diagnosing the inclu- sion, inaccurately correlate the effects of all the molten metal and casting process contributing factors, and incorrectly blame the melting depart- ment for producing and delivering “bad metal.” Tis session will provide a guideline to better understand the interrelated aspects to define molten metal quality.
Panel: Te Skin I Am in—Effect and Control of Gray Iron Skin on Ductile Iron and Compacted Graphite Iron Castings (17-117) Charles Monroe, University of Ala- bama at Birmingham (Birmingham, Alabama); Brandon Reneau, Caterpil- lar Inc. (Mapleton, Illinois); David Gilson, SinterCast Inc. (Naperville, Illinois); Mark Osborne, American Castings LLC (Pryor, Oklahoma) Gray iron skin on ductile and
compacted graphite iron cast- ings has become a bigger issue for casting performance as designers get closer to design limits. Panel presenters will discuss the effect of
