| Abstract: |
| The work aims to improve surface quality of metallic card clothing (MCC) products (made of high carbon microalloyed steel), decrease Ra value of card-clothing surface, and effectively enhance using effect of the products. Process study was applied to card clothing products by adopting plasma electrolytic polishing process, and effects of different electrolyte concentration, production speed and plasma electrolytic polishing cell groups on surface roughness of card clothing were investigated. Polishing quality of card clothing was characterized with non-contact surface roughometer and determined based upon roughness Ra indicator. Plasma electrolytic polishing process could be applied to realize surface polishing of steel materials, the polishing would not only remove oxide scale on the surface of card clothing effectively, but also make the surface smooth and have mirror effect. Surface roughness Ra reached 0.11 µm based upon the optimum process parameters (electrolyte concentration as 2.75%, routing speed as 40 m/min, and plasma electrolytic polishing unit as 4 groups). The process of EPPo has been successfully applied to steel materials. This non-contact continuous polishing process is made possible, which keeps workpieces intact, makes the surface bright and smooth, and features in environmental protection, energy conservation and high production efficiency. |
