轧辊表面螺旋纹的影响因素及控制措施

Influence Factors and Control Measures of Spiral Groove on Roll Surface

热轧板带精轧机工作辊辊面的螺旋纹在轧制过程中压印至带钢表面,使带钢表面产生条纹状缺陷,经分析,确认导致轧辊表面产生螺旋纹的主要原因是轧辊辊型和轧辊磨削参数设定不合理。通过优化轧辊磨削参数以及轧辊辊型曲线,消除了轧辊表面螺旋纹。

The spiricle on the working roll surface of finishing mill for hot rolled strip is embossed to the surface of strip during the rolling process,resulting in striated defects on the surface.Through analysis,it is confirmed that the main factors causing spiricle on roll surface are unreasonable setting parameters of roller profile and grinding.The spiricle on roll surface is eliminated by optimizing the grinding parameters and curve of roller profile.
