The dry recovery of valuable scrap from the residual slag at the production of Stainless Steel and Ferro-Alloys using the Sensor Separation Technique.-The RecCo-Marilyn Process

摘要

Presently all stainless steel mills are rapidly increasing their production due to a high demand on stainless steel. Stainless steel scrap is an essential feedstock for the stainless steel production and has reached levels of 1350 euro ton f.o.b. Rotterdam. The higher the price; the lower the quality! Consequently maximum of own residual scrap from slag with known quality is very essential. Conventional producers have slag quantities of 30-40 percent of steel making tonnages, containing 6-12 percent retrievable scrap.
