Effects of Scrap Charges and Other Variables on the Quality of Iron Castings: A Progress Report

  • Description:
    The cast-iron foundry industry has expressed concern regarding the quality of scrap used to prepare iron castings owing to the growth of alloy steel production and its influence on tramp element levels when recycled. Reliable and current information is unavailable on the amount of tramp elements contained in iron castings produced over a significant period of time. Accordingly, the Bureau of Mines is analyzing cast iron samples from the participating foundries throughout the United States on a quarterly basis under a memorandum of agreement between the Bureau and the American Foundrymen's Society. Each sample is analyzed for 28 elements to determine if the level of tramp elements in charge materials is changing over time. Preliminary results indicate that the type of furnace, the geographic location, and the size of the foundry did not significantly affect casting compositions. Owing to the variability of charge materials used, correlation of the analyses of the castings with charge compositions had not been possible. The data obtained are undergoing statistical analysis to determine significant differences among the chemical compositions as a function of time and foundry location. [Description provided by NIOSH]
