An analysis was conducted on the mechanisms and influencing factors of short scratch defects on the surface of cold rolling strip steel rolls during the grinding process. It was found that the short scratches on the roll surfaces, characterized as fine, intermittent linear marks, were closely related to grinding wheel vibration, improper characteristic matching and inadequate settings of grinding fluid parameters. Effective reduction of short scratches during the grinding process can be achieved through adjustments to grinding wheel, grinding fluid and grinding process parameters. These improvements not only enhanced the surface quality of the rolls but also increased grinding efficiency and the surface quality of downstream cold-rolled products. The short surfcace scratches were significantly reduced after implementing optimizations in the grinding process of rolls at a certain cold rolling mill demonstrated over a year and a half of practice, thereby substantially improving the quality of the steel plate surface.
