Abstract

Stress state of metal in deformation zone during introduction of the separating collars of the grooved die into continuously casted steel slab was calculated for production of section billets on the unit of combined continuous casting and deformation. Calculation of axial, tangential and equivalent stresses arising in deformation zone of metal was made in four sections of deformation zone and its results are presented in specific points and lines. View of the section of deformation zone and location of specific points are provided. The stress state of metal in zone of cyclic deformation at formation of three steel section billets from continuously cast slab by separating collars of grooved die on the unit of combined continuous casting and deformation was determined by solving extensive problem of elasticity with the finite element method using the ANSYS package. The results of calculation of axial, tangential and equivalent stresses according to Mises in deformation zone are given in form of graphs and tables for working surfaces in four cross sections. The values and regularities of distribution of these stresses along the length and width of deformation zone were determined. The character of axial stresses distribution by characteristic lines located along the length of deformation zone is shown. Values of the highest compressive and tensile axial stresses arising in deformation zone during introduction of separating collars of grooved were obtained for the unit of combined continuous casting and deformation.

Summary

Introduction

Результаты расчета осевых, касательных и эквивалентных напряжений, возникающих в очаге деформации металла при получении трех сортовых заготовок, выполнены в четырех сечениях очага деформации. Напряженное состояние металла в очаге циклической деформации при формировании разделяющими буртами калиброванных бойков из непрерывнолитого сляба трех стальных сортовых заготовок на установке совмещенного процесса непрерывного литья и деформации определено путем решения объемной задачи упругопластичности методом конечных элементов с использованием пакета ANSYS. Определены величины и закономерности распределения осевых, касательных и эквивалентных напряжений по длине и ширине очага деформации при получении трех сортовых заготовок на установке совмещенного процесса непрерывного литья и деформации.
