Abstract

The scale removing process with acid, generally called as the pickling process, is accepted by the steel producers satisfactorily. However, most of the producers tend to develop scale removing process without acid due to the environmental regulations. In the related literature, some methods were studied for finding eco-friendly solutions. Although these studies seem to be promising, pickling process is still dominant as a descaling process before cold rolling applications. In this study, efficient surface cleaning method which is called as dry ice blasting method was used under different parameters on the carbon steel surface as it might be used instead of pickling process. Results of the experiments were studied by observing cross-sectional micro structure of samples. In addition, before destroying samples for hot mounting application, the surface topographies were measured by non-contact device. Finally, surface roughness values of the samples were showed on figures.
