Mill scale (37% of the total steel rolling) is a expensive secondary material due to its high iron content, low impurities and stable chemical composition. The mill scale from the rolling process and all iron bearing wastes generated at the iron and steel plant site are commonly recycled into the sintering plant to produce high quality sinters.
NO x emissions and their mitigation technologies Characteristics of NO x emissions. NO x is associated with air pollution problems such as "photochemical smog." In Japan, the amount of NO x emitted from sintering plants accounts for the majority of total NO x emissions from integrated steelworks (Morioka et al., 2000).
Mill Scale Mill scale is good auxiliary materials for sintering which could improve the permeability of sinter bed, and at the same time increase the sintering productivity. Usually, the domestic steel company will sinter according to oxidized scale and powder grinding as proportion of about 1:10.

Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, magnetite).. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.
