“…The rolling factors impact not only the surface roughness of the material and the rolls but also the surface topographical orientation of the rolls. To minimize extra tensile stresses that may induce ripping in the strip width direction, Mazur reasoned that the surface micro-relief should be consistent along the roll-barrel axis (Mazur 2015).…”

This study investigated the effect of rolling parameters such as speed, thickness reduction, roll surface roughness, material thickness, surface condition (dry or lubricated), and rolling force on the roughening characterization in asymmetrical rolling. The surface roughness of the samples subjected to rolling tests was measured. The roughness values' average and standard deviation were found, and 3-D scanning images were acquired. Lubricated texturing experiments revealed that lubrication reduced roughness transfer. It was found that the introduction of roughness on the material surface decreased as the rolling speed increased. On the other hand, a higher speed increases the rolling force, which increases the surface roughness. The effect of speed on the standard deviation varies in direct proportion. Furthermore, lubricated rolling produced a more homogenous roughness distribution at higher speeds, while dry rolling produced homogeneous roughness at lower speeds. It was revealed that the rolling force is higher with thicker materials. While the roll roughness did not affect the rolling force using thicker material much, this effect was more pronounced in the very rough roll using thinner material. The standard deviation was lower in smaller reduction ratios using rough and very rough rolls. According to the results, although asymmetrical rolling has some advantages compared to conventional rolling, it was concluded that it is not a suitable method for roughening steel strips.

“…The quality of the surface of the cold rolled steel strip directly determines the quality of the product being processed and the downstream processes [ 1 , 2 , 3 , 4 , 5 , 6 ]. The surface topography is the foundation of the surface quality control of the cold rolled steel strip and is formed on the strip surface during the rolling process [ 7 , 8 ]. Research into the transfer mechanism of the surface topography of cold rolled steel strips has been the focus of scholars.…”

Automobile and household appliance panels require steel strips with extremely high-quality surfaces. Therefore, an in-depth study of the surface topography transfer of the steel strip during the rolling process is of considerable significance for improving product quality. In this study, the scale-invariant feature transform (SIFT) algorithm is used to realize the large-field stitching and the correspondence measurement of the surface topography of the roll and strip. The surface topography transfer mechanism and microconvex change law during cold rolling are revealed. Further analysis is conducted regarding the effects of different reduction rates and the initial surface topography of the roll on the formation of strip surface topography. Experimental results reveal that the furrow phenomenon occurs during the rolling process owing to the backward slip effect but is eliminated by the elastoplastic deformation of the matrix and the forward slip action. No furrow occurred along the width direction of the strip. With an increase in the rolling reduction rate, the transfer rate increases, and the strip surface topography is closer to the roll surface topography. Under the same rolling roughness condition and a small reduction rate (5%), the transfer degree increases remarkably with a rise in the reduction rate and increases slowly as the reduction rate continues to grow (from 7% to 10%). This study serves as a theoretical basis for the subsequent improvement of the surface quality of cold rolled strips.
