| Abstract Scope |
In secondary steel production, copper and tin contamination cause surface defects and loss of ductility in steel products. These tramp element contents are rising in steel scrap due to increased use of steel scrap generated by the automotive and electronic industries. To overcome this problem, dilution of the charge using low copper scrap has been the solution. However, this solution limits the use of steel scrap in steel recycling.
Theoretically, there are few methods available to reduce the tramp elements concentration in scrap. This presentation will describe some of the pyrometallurgical methods for lowering of bulk scrap contamination and hydrometallurgical techniques to control the surface impurities. Thermodynamic possibilities have been discussed by other research groups. This paper will elucidate some experimental results. |
