| The red scale formation in hot rolled steel profiles is a chemical iron oxide reaction that disrupts the natural color of the surface of the steel. Tempering temperature, atmosphere, time and rolling temperature, silicon content in the chemical composition of the raw material affect this formation. In this study, red scale formation on the surface, which is a very rare case in steel profiles produced by hot rolling method, was investigated. Samples were taken from a production which appeared in the forms I and U in the produced profile types. The profiles in which red scale formation is observed are as follows; visual inspection, spectral analysis, XRD analysis and microstructure analysis. According to the findings of the analysis and literature, it was found that the red scale formed in this case has no correlation with the ratio of silicon element. It has been found that the red scale formation of different density in I and U profiles depends on the accumulation of water depending on the rolling position of the profile during rolling. In general, it has been found that hematite scales cause red scales due to cooling effect. |
