This article presents a new technology for the production of flat products from brass with a fine-grained structure. In work the screw-shaped condition (VAT) of a preparation at rolling in spiral-shaped rolls is investigated. The finite element method and the ANSYS-LS / DYNA program yielded quantitative data and established the main regularities of the distribution of VAT and temperature in the computer simulation of rolling in screw-shaped rolls with different number of passes. The rational regimes of deformation of blanks in screw-like rolls are determined, allowing a uniform distribution of the accumulated deformation to obtain bands of high quality without disrupting the continuity of the material.
Keywords: brass Л63, flat products, rolling, stress-strain state, numerical modeling, intensity of stresses and deformations
