Abstract
The present invention relates to a method of steel sheet surface treatment, wherein, the method comprises sequentially: a strip surface treatment unit () configured with a high pressure spraying device (-) or a centrifugal ejecting device (-), a strip surface rinsing unit (), and a strip surface dry unit (). Either or both of the high pressure spraying devices (-) and the centrifugal ejecting devices (-) are arranged, and spray onto the strip surfaces with a mixture of solid abrasives and water, i.e., slurry. Additionally, the method of steel sheet surface treatment comprises: a slurry supplying unit () and an abrasive recycling unit (). When the method of the present invention is applied into the strip post processing line, it can control the surface roughness of the steel sheet, while clearing away grease, scales and some contaminations thereon, through impacting the mixture of water and solid particles with a certain ratio onto the surfaces of the strip steel. When the method of the present invention is applied into the finishing processing line, it can control the surface roughness of the steel sheet, while adjusting the mechanical properties of the strip, thereby completely or partially replacing the skin pass process.
