>Several melting and casting techniques which have been successfully used for purifying refractory metals were evaluated as methods of upgrading automotive scrap steel. These methods include (1) nonconsumable electrode arc melting, (2) electron beam melting, (3) vacuum arc melting, (4) vacuum induction melting and (5) electroslag remelting. The removal of copper, chromium, and tin from the scrap was of primary interest since these impurity elements are not removed during the steelmaking process but are known to adversely affect the mechanical properties of steel. The optimum conditions for impurity removal by melting techniques were determined using simulated auto scrap in small scale melting experiments. (JRD)
