Steel Production based on Scrap and Direct Reduced Iron DRI

2 Steel Production based on Scrap and Direct Reduced Iron (DRI) 

The second route to steel is via an electric arc furnace, a common method of reprocessing scrap metal along with some DRI (direct reduced iron) for chemical balance to adjust the content of unwanted impurities like Cu. DRI is produced by reduction with gas (H2, CO) or coal 85% is based on natural gas that is converted by steam reforming into the reduction gas (Section 6.2.4).
