Study on Deformation Penetration of Rolling Process by Rolling FEM Model of Wedged Ingot

Abstract

In order to study the law of deformation penetration in thickness direction of the plate, 3D finite element model of wedged ingot rolling has been developed by means of software ABAQUS, in order to quantitative study the influence of reduction rate on the deformation penetration effect of steel plates, on the same reduction amount of whole wedged ingot and different reduction at different locations of the wedged ingot. Two pass rolling tests of small rolling mill on 120 mm thick wedged plate has been conducted. Finite element calculation and test results show that the center of plate almost no deformation when the reduction rate decreased to a certain extent ( < 15%) and the center of plate deformation rate increased significantly with the increase of the rate of pass reduction.
