One of the best ways for foundries to measure the accuracy and quality of their production practices is to examine those of their colleagues. Through this examination, foundries may be able to learn a new "trick of the trade" or method of production that will improve their own casting operation.This article examines three foundries' production practices in the conversion of their base gray iron melt to base ductile iron. The foundries examined are Brillion Iron Works, Inc. (BIW), Brillion, Wisconsin, Burnham Foundry, Zanesville, Ohio, and Giddings & Lewis Castings (G&L), Menominee, Michigan. As the most critical phase in ductile iron production, melt preparation determines the ultimate metallurgical success or failure of the castings. By examining the methods utilized by the three firms in this article, other ductile iron foundries will have points of comparison with which to deter-mine the efficiency of their melt con-version methods.
