为了提高轧辊表面强度, 减小应力集中, 延长轧辊寿命, 利用光纤激光毛化设备对轧辊表面进行无序毛化。研究了激光功率、轧辊转速、激光头平移速度以及脉冲频率对无序毛化点分布的影响, 提出了四种无序毛化的方法, 即: 速度调试法、频率调试法、外部调试法和综合调试法。实验结果表明, 四种方法都可以实现无序毛化, 其中综合调试法无序化程度更大, 毛化质量最佳。研究结果已应用于实际生产。

In order to improve the roll surface strength, reduce stress concentration and extend the roller life, it used the fiber laser flexible workstation to texture surface of roller. It was studied how laser power, roller rotate speed, laser head speed and Pulse frequency affect the arrangement of Disorder texturing. Four methods for disorder texturing have been proposed, inculding change the speed, change the Laser Head posture, change the Pulse frequency, comprehensive adjustment method. The results showed that, four methods all can realize the disorder texturing and the fourth method is better than others. The results have been applied to actual production.
