Steel And Iron Slag by European Recycle Ltd.. Supplier

Steel and iron slag Oxide dusts, sludges, scales, slags and spent refractories are co-products of the iron and steel manufacturing process. These residues generally represent 6-7% of the whole steel production. Their production arises from the conversion of ores to iron, hot iron to steel, and from melting scrap in an electric arc furnace or from the subsequent treatment of crude steel.
