This article presents the results of a study on steel strip plasticization during straightening on roller straightening machines. The studies were conducted using the SIMULIA Abaqus finite element analysis system and with the implementation of an industrial experiment on straightening and plasma cutting of hot-rolled profile rolled stock. A significant effect of strip plasticization during straightening under conditions of alternating deformation on the deviation from the flatness of the profile rolled stock at high-tech processing is presented. The results confirmed that the minimum deviations of the strips from the flatness after cutting, not exceeding 2 mm, correspond to the straightening modes with a high plasticization of the strip at the beginning of straightening and the smallest at the end with the reduction of residual longitudinal stresses in thickness. The regression dependence of the strip plasticization on the main parameters of the straightening process based on the processing of a computational experiment was obtained, and its adequacy was established. Moreover, the parameters affecting the plasticization of the steel strip during straightening to a great extent are the number of rollers and difference in the vertical movements of the first and last rollers of the upper cassette.
The model developed for predicting the plasticization of a hot-rolled steel strip enables to develop recommendations for setting up roller machines to increase the impact on the shape of rolled products and evaluate the straightening process when designing and modernizing existing metal cross-cutting lines.
