The surface condition of titanium strip has always been a key focus of researchers. This study delves deeply into the formation rules of the surface morphology of TA1 titanium strip after cold rolling. By observing the surface morphology of TA1 titanium strip at different rolling passes, it is found that the uniform pits formed by shot peening gradually decrease in number during subsequent rolling, and meanwhile, a scaly morphology emerges and gradually becomes more prominent. During the rolling process, the "valley" and " peaks" on the surface of the working rolls will be transferred to the surface of the titanium strip. After the "protrusion of titanium strips" are flattened, the "scaly" morphology is formed. Moreover, the greater the rolling reduction, the more severe the folding at the " protrusion of titanium strips ". The study proposes that reducing the reduction in subsequent passes, improving the lubrication conditions, and reducing the surface roughness of the working rolls can effectively improve the "scaly" morphology, thereby enhancing the surface quality of TA1 titanium strip and providing a theoretical basis for optimizing the cold rolling process of TA1 titanium strip.
