摘　　要：分析本钢特钢小棒材表面划伤产生的原因,通过对轧机工装精度提升的管控,空过辊道两侧加装惰轮,设计制作裙板耐磨锥轮,有效解决小棒材表面划伤问题,显著提升成品表面质量,缩短交货期,降低生产成本。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.
