In the fundamental studies a mill scale was rarely used as an iron oxides bearing component of self-reducing mixture. Therefore, in the first paper,1) the chemical and morpho-logical characteristics of the mill scale were investigated together with its reduction behaviors. The chemical and structural characterization of the mill scale showed that
