Presentation Abstract:
The intent of the presentation is to show the factors that affect the efficiency of Mg recovery, highlighting the most recent improvements to the treatment process. This includes means to get the ladle full of iron prior to the start of the Mg reaction, as a result of prompt ladle filling, improved alloy pocket designs, and longer delay cover materials. For foundries that redesign their process to Mg treat, inoculate, and pour from the same ladle, a very large drop in melt and treatment temperature can be provide a huge boost in Mg recovery. Such processes require lower Mg content alloys to avoid spillage and these alloys often replace higher Mg content alloys with no increase in addition rate. Alternatively these same benefits can be used by a 2 ladle process if the treatment ladle is transformed into a transfer ladle, and the pouring ladle at the casting area is used for treatment, inoculation, and casting. The very high recovery rate of these alternatives results in very low slag generation which cleans up the process with very consistent results.

Presenter: Doug White, Technical Services Manager, Elkem Materials Inc.
Mr. White received a Bachelor of Science Degree in Metallurgy from McMaster University in 1970. After a brief period at the Steel Company of Canada R&D Dept., he joined Crouse-Hinds of Canada, a gray iron and aluminum foundry. While there, Mr. White set up the melt and pour cycle of a new coreless induction furnace line and then continued on as a supervisor. In 1974 he joined Union Carbide Canada Ltd., Metals Division. This business was later purchased and became Elkem Metal Canada Inc. In addition to Canada he has held positions with Elkem in: Oslo, Norway; Antibes, France; Pittsburgh, PA; Ashtabula, Ohio; and now Boca Raton, Florida. Mr. White’s activities have involved foundry technical service for gray and nodular iron manufacture, design and manufacture of nodulizers and inoculants, and desulfurization technologies. He has presented papers/technical seminars and has visited foundries in Canada, Europe, SE Asia, Australia, Brazil, Mexico and the United States. Mr. White served as President of the Ontario Chapter of AFS (1981-1982), and currently serves on the DIS Research Committee. In 2014 Mr. White presented the honorary lecture at the AFS Casting Congress and the year before received the AFS Award for Scientific Merit.
