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. Mill scale is composed of iron oxides mostly ferric and is bluish black in color. It is usually less than 1 mm ( in) thick and initially adheres to the steel
Feb 01, 2016· The XRD analysis of sample C in Fig. 5 shows peaks of Hibonite (calcium aluminosilicate) and Gehlenite (aluminium silicate) phases. The formation of these phases can be expected due to presence of CaO, Al 2 O 3 and SiO 2 in the bulk refractory matrix. In this sample there is no formation of some alkali or iron based phase which clearly explains ...
