What exactly is Mill Scale and what is done about it

The alloying metals form cations within the mill scale at about the alloying proportions* due to the almost instantaneous oxidation of freshly exposed metal at high temperature Fe3O4 contains both Fe+2 and Fe+3, and is sometimes written FeO·Fe2O3 Ni+2 substitutes for Fe+2, Al+3 and Cr+3 substitute for Fe+3 Thus, (Fe,Ni)O·(Fe,Al,Cr)2O3The increasing role of direct reduced iron in global ,The Direct Reduction process Direct reduction processes can be divided roughly into two categories, gas-based, and coal-based In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust etc), in order to convert the ore,Direct Reduced Iron - Platts,Direct Reduced Iron: DRI is typically produced in pellet form and can be loaded directly into an EAF, Blast Furnace, or Basic Oxygen Furnace It contains a very high iron content (typically >90%) DRI exits the DRI module at a high temperature, and can be fed directly into
