[Abstract]:With the rise of micro-manufacturing and micro-manufacturing technology of 3C products, the development and industrialization of rolled ultra-thin strip has become a new hotspot in the fields of electronics, computer, medical treatment, energy, transportation and so on.This paper analyzes and discusses the research, production and application of various kinds of extremely thin metal strip, and introduces the typical rolling mill and products of the very thin strip rolled in the world.This paper introduces the new development of the research on minimum rolling thickness under asynchronous rolling condition, and gives a new formula of minimum rolling thickness considering the ratio of rolling area.This paper mainly introduces three new discoveries in the study of extremely thin strip rolling, such as superextension, atypical plasticity and deformation-induced reaction diffusion, and analyzes the causes from the second kind of micro-scale effect.In this paper, the phenomena of single crystal, processing softening, size effect and so on are analyzed, and some characteristic parameters in strip rolling are put forward, which are used to analyze the rolling mechanism of very thin strip.This paper introduces the application of crystal plastic finite element method in the analysis of extremely thin strip rolling, and points out the development direction of rolling extremely thin strip.
