The effects of hot rolling and descaling conditions on the strip surface color and scale structure were examined.Irrespective of Si content …

authors : Tomoki Fukagawa, Hikaru Okada, Yasuhiro Maehara link : 10.2355/isijinternational.34.906 Abstract : The red scale, which is one of the major defects on hot-rolled Si added steel sheets, is reproduced experimentally. On the basis of detailed observation of the scale properties, we propose the mechanism of formation of the red scale. Imcomplete descaling of FeO prior …

The composition of oxidation atmosphere used in this work was chosen to approximate atmospheres found in industrial steel billet reheat furnaces. In order to study the effect of adding each gaseous component in these atmospheres experiments were …
