Abstract：This article analyzes the causes of scratches on the surface of small-level bars in Benxi special steel. By improving the control of rolling mill tooling accuracy， idler wheels are installed on both sides of the roller table， and wear-resistant cone wheels of skirt plate are designed and made， which effectively solve the problem of scratches on the surface of small-level bars， significantly improve the surface quality of finished products， shorten the delivery time and reduce the production cost.

Key words： small-level bar; scratch; quality of tooling；roller table；skirt plate; cooling bed
