The Steel Founders' Society of America Quality Assurance Task Force identified oxide macroinclusions as a universal problem experienced by users of steel castings. SFSA along with the Department of Commerce and the Department of Energy sponsored research directed at reducing the occurrence of macroinclusions in steel castings. The Clean Cast Steel Technology program investigated melting practice, pouring practice, ladle treatment, and special devices such as filtration and analog simulation of mold pouring and filling. An overview is given on the results obtained to date.
