Most of steel products are manufactured through rolling process. Therefore, rolling process is very important for the qualities of rolled products. In the process of rolling, the temper rolling is assumed to be very important process that gives influence on the qualities of products such as the shape and roughness. However, as there is not any reasonable theory to control the surface roughness of steel strips, it is said that actual operations depend on experience and intuition. The surface transcription in temper rolling is an important process to decide the roughness of strips surface as the industrial product. But, the influence of lubricants on the surface of rolled strips and the mechanism of surface transcription have not been understood yet. In this paper, the influence of rolling conditions, such as roll diameters, roll surface processing, lubricants and rolled materials, upon the surface transcription is investigated. As a result, it is found that such rolling conditions have important effects upon the surface transcription.
