Abstract

Abstract:To control the oxide scale on high carbon steel during the manufacture of high carbon steel wire, the structure and the growth process of oxide scale were investigated by using X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM) , Laser Raman Spectroscopy (LRS) and TGA system. Experimental results show that oxide scale on high carbon steel has a three-layer structure. The oxide scale growth on high-carbon steel can divide into three stages. 1) The growth rate is slow below 780°C. 2) The growth rate increases obviously between 780°C and 950°C and 3) sharp increase beyond 1000°C. The oxidation of high carbon steel obeys a linear law at first and a parabolic law is followed with the increase of oxidation time. The oxide temperature has great effected on the thickness of oxide scale. The proportion of wustite in oxide scale increases with both the oxidation temperature and oxidation time.
