Shape Research And Finite Element Simulation On The Rolling Of AZ31B Magnesium Alloy Sheet

Magnesium alloy sheet, with low density, high strength easy to heat, good cushioning,has been widely used in the fields of automotive industries, aerospace,3C products and soon. There are kinds of magnesium alloy sheet products, in which AZ31B is widely used.However, due to its poor plastic processing ability in room temperature, processingdifficulties, immature rolling process, prone to flatness problem, magnesium alloy can’tbetter meet the high-quality requirements of modern products Therefore, the research formagnesium alloy strip forming regularity has an important practical significance andeconomic value in the process of China’s economic development and industryrestructuring, as well as makes it for industrialization. The key research contexts of thisarticle as follows:The finite element model of1650mm six-high mill is built based on the given actualproduce parameters. In the offline state, the simulation of magnesium alloy’s strip rollingis conducted in different technologies and methods which includes regulated intermediateroll shifting length, regulated intermediate roll bending force and regulated working rollbending force, and the effect rules on roll’s elastic deformation, strip’s elastic deformation,a load roll gap shape and rolling force are obtained.The rolling parameters on the influence rules of the export plate’s convexity ofmagnesium alloy by simulating research on different technologies. The predictive modelsunder three regulated methods are conducted by the simulated results. Meanwhile, thepredictive models are revised by considering the interactive influence between rollingvariable factors, and the program of the plate convexity’s predictive values is alsoprogrammed by VB language.
