Abstract

Rolling process is implemented in the production of structures that are regularly utilized in vast applications such as pipes, frames, shells, discs and many other applications. Flat rolling is one of the widely used rolling processes. Flat rolling involves reducing the thickness of a metal sheet by feeding it between two rollers that are separated by a prespecified distance, and this can be done under hot conditions (hot flat rolling) or cold conditions (cold flat rolling). Due to the significance of flat rolling applications, optimizing this process became a crucial necessity in today’s industrial revolution. In this paper, Simufact Forming Simulation Software was utilized to extract critical results such as effective plastic strain, effective stress, spread, and maximum rolling force under different rolling conditions. The paper studied the effect of the rotational velocity of the rollers on the previously mentioned parameters, furthermore, the relationship between these parameters and friction coefficient was identified. The general trend of the extracted data showed an increasing yet fluctuating connection between the parameters verses the rotational speed and the friction. Finally, the trends were used to characterize the best conditions for flat rolling applications.
