study on reducing and melting behavior of mill scale/petroleum coke

the reducibility and metallic yield of selfreducing mixture comprised of mill scale and petroleum coke, as well as to measure the carburization of the iron products formed. Therefore, this study is a part of longterm project to get an inside on the possibility to use selfreducing blends/ agglomerates in electric arc furnace.

What is the appliion of iron mill scale? Can I extract

Iron mill scale can be recyled in steel plants as a mix component in production of iron ore sinter. It can be used in along with other iron bearing materials in for production of sponge iron. Mill scale after proper cleaning and treatment can be used for production of iron powders for use in powder metallugy appliions.

Conversion of Mill Scale Waste into Valuable Products via Hindawi

Aug 30, 2015 A study on laboratory scale was made to use mill scale waste to prepare iron powder. The authors used CO followed by H2 as a reducing gas. When the reduction was carried out by carbon monoxide the maximum iron content (98.40 wt% Fe) in the iron powder was obtained at 1050°C for 180 min.

Treating Or Using Mill Scale Patents and Patent Appliions (Class

Abstract: According to the invention, oilcharged millscale is treated such that the oil is encapsulated or bound therein. An escape of oil on use in a shaft oven first occurs when the ignition point is reached, thus guaranteeing combustion. Agglomeration of said mixture is by pelleting. A mixture comprising the following is
