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.

The Carbon Cost of Slag Production in the Blast

2016-2-5  The quality of raw materials (iron ore, coal, and coke) has a clear impact on the carbon emissions of the hot metal production in steel making. So far, very little work has been done to measure and quantify this impact. Yet for benchmarking, technology choice and general carbon optimization are important elements. The total slag production of a blast furnace gives an accurate and relevant .
