INFLUENCE OF TRAMP ELEMENTS IN THE PRODUCTION OF HIGH-QUALITY STEELS USING THE SCRAP ELECTRIC-ARC FURNACE ROUTE

Driving forces for increasing the share of electric are furnace steelm aking are strong : availability of scrap, pressure to recycle material s, economic benefits. This trend leads to an increase in the level of tramp elements in the steel products. The purpose of this work is to i nvestigate quantitatively the potential problems related to increased levels in tramp elements, Our objectives are to discuss, on a case by case basis, the currently existing practical limits and to devise coun termeasures to further extend these limits.
