Chemical Weight Analysis of all the samples was done to determine the iron content in the reduced mill scale samples at every stage. The process followed for chemical weight analysis involved making a 0.1 N K 2 Cr 2 O 7 solution which was used for the estimation of Fe in the sample.
Chemical analysis of the as-received mill scale samples was done by X-ray fluorescence (XRF) technique. The X-ray powder diffraction patterns on the raw, reduced and post-MSR samples were collected at room temperature on a Philips diffractometer (PW 3050/60 X'pert Pro), using monochromatic CuK α1 radiations ( λ = 1.54056 Ǻ) and Ni filter.
Mill scale mill scale is a layered and brittle material, composed of iron oxides with wustite as a predominant phase. It is normally considered as waste material. From the chemical and physical analysis performed on the mill scale, and with respect to the environmental concerns, mill scale is considered to be non-dangerous waste and normally ...
Mill scale, is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling hot iron or steel billets in rolling or steel mills. It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color.
