    Purchased scrap is generally accepted as a major source of residual and unspecified elements in steel. Current trends in the steel industry will precipitate a more important role for scrap as a raw material. A principal factor in minimizing residual elements is the monitoring and control of this nonhomogeneous, nonmanufactured product by scrap processors and steel producers. By examining the variation in scrap grades through computer analysis and by integrating various techniques such as material segregation, inspection, and statistical process control procedures, more predictable and potentially lower residual levels can be achieved.
