Web Application for Calculating Roll Calibrations in the Production of Curved Rolled Sections and Tube Stock

Abstract

A computer program complex is described for calculating roll calibrations, energy-force parameters and stress-strain state of the metal in the production of curved rolled profiles of practically any real configuration, as well as the formation of a wide billet tube assortment. The system also includes a database of domestic and foreign ferrous and non-ferrous metals and alloys, containing chemical compositions of materials, their technological, mechanical and physical properties. The programs allow you to get a complete set of drawing documentation, the distribution of stresses across the width and thickness of the strip, the forecast for the level of residual stresses. The software package was created as a Web application for use on the Internet and is posted on econom.misis.ru. Previous versions of the program in the form of Windows applications, as well as this option were used by a number of organizations to calculate roll calibrations in preparation for the production of curved profiles. The program for calculating the formation of tubular billet, predicting changes in the stress-strain state of the metal across the width and thickness of the strip, springback and residual stresses, was tested when analyzing the production process of welded longitudinal pipes of a wide profile range of stainless steel on the Olimpia 80 production line.
