Direct reduced iron 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 to metallic iron, without melting it (below 1,200 °C (2,190 °F))...

Investigation on the Coal The properties of the mill scale pellets are found to match the desired specification for the direct reduction process, and the reduction behavior of the pellets as a function of temperature, time, and coal-to-mill scale ratio suggests that iron making from mill scale through this ,...
Mill scale reduction by coal Millscale consists of iron and its oxid This study shows the condition of mill scale reduction, a by-product of iron and steel formed during hot rolling of steels, with low grade coal to produce iron powder In this paper an attempt has been made to study of effect of addition of calcium carbonate on reduction behavior of millscale...
