  • Description:
    Foundrymen have 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 made over a period of time. Accordingly, the U.S. Bureau of Mines, in cooperation with the American Foundrymen's Society, analyzed cast iron samples from participating foundries throughout the United States on a quarterly basis to ascertain possible trends. Each sample was analyzed for 28 elements to determine if changes had occurred as a function of several input variables from January 1981 through September 1986. Results show that iron casting compositions had changed with respect to a few tramp elements such as as, b, CO, and sn over the 5-3/4- year period. Changes in charge compositions probably are responsible. A few significant regional variations also were observed with respect to al, as, CO, cr, cu, and mn. [Description provided by NIOSH]
