Outline
To improve the surface quality of high-end plates by descaling and cleaning process, an experimental study was carried out with different process routes that are determined based on the combination of Steel Eco Descaling (SED) technology and other surface pretreatment processes. Based on the analysis of surface appearance, surface roughness, surface micromorphology and surface energy spectrum of the plates treated by different processes, an optimal descaling process is finally determined, consisting of SED, soaking with roller brush cleaner, polishing with scouring pad buffering wheel, and high-pressure flushing. After cleaning treatment with this process, the plate sample is overall in a uniform metallic color, with significantly reduced surface roughness and oxygen content. It is concluded that after treatment with this combined process, surface quality of the third-generation advanced high-strength steel (AHSS) plates for automotive can be effectively improved.
