DIGITAL SOLUTION FOR ROLL PASS DESIGN PROCESS OF SIMPLE PROFILES

Abstract

Complex and expensive programs have not yet found wide application for solving production problems on rolling mills. The main emphasis is mainly on practical experience and production experiments. At the same time, optimization of the production process only on the basis of experimental studies is associated with significant time and financial costs. Therefore, it is also ineffective. This has led to the fact that currently a few leading organizations and scientists are engaged in the development of high-speed engineering computer systems for automated design of profile rolling calibers. The purpose of this work is to develop a digital solution for optimal roll pass design, as well as for analyzing the efficiency of rolling equipment adjustment based on a universal mathematical model of continuous rolling of simple profiles in the «oval-circle» calibers system. The proposed model uses the variational principle of continuous medium mechanics of the minimum total power of internal and external forces of the deformation zone – the Ritz method. The developed mathematical model can be used to study the metal deformation during continuous rolling in the “oval – circle” calibers system. This model is also recommended for use as a calculation module for determining metal deformation during rolling in a high-speed wire block with a joint drive.
