Precise detection was conducted on core parameters such as the surface micro-morphology, roughness, work-hardening degree, and magnetism of the strip steel after wet shot blasting descaling through systematic experiments. The results showed that there was no residual oxide on the strip steel surface, and the steel grit was not embeded into the strip steel substrate. Moreover, the surface state of the strip steel after descaling was quite consistent with that before descaling, which fully confirmed that this technology could endow the strip steel with excellent surface quality. In addition, based on the multi-combinations of different shot diameters and velocities, in-depth analysis of the descaling process was carried out using finite element simulation, revealing the internal mechanism of wet shot blasting descaling. The optimal descaling effect was achieved with a steel shot particle size (D) of 0.6 mm and a shot blasting speed (v) of 38.10 m/s. These findings provided important theoretical basis and technical guidance for the optimized application of acid-free descaling technology in actual production.
