对采用不同毛化工艺的冷轧带钢表面微观形貌进行了分析,并以3.5μm的电火花毛化辊为研究对象,对其平整轧制过程中辊面和板面粗糙度的衰减曲线进行了试验研究。在大量试验数据和理论分析的基础上,获得了平整轧制过程中带钢粗糙度衰减规律,从而为成品带钢表面粗糙度的控制提供了指导。 The surface morphology of the cold-rolled strip with different texturing processes was analyzed. The surface roughness of the roll surface and the plate surface during the flat rolling process was studied by 3.5μm EDM roughening roll Conducted a pilot study. On the basis of a large amount of experimental data and theoretical analysis, the law of the attenuation of strip roughness in the process of smooth rolling was obtained, which provided guidance for the control of the surface roughness of finished strip.
