Application of Modified Slab Method in Asymmetrical Plate Rolling

author

Abstract:

In this paper, an analytical method based on Modified Slab Method of analysis is presented to study the asymmetrical rolling process due to difference in work rolls radii, rolls speeds and interface frictions. The shear force imposed on material along the contact region is considered to be a function of the frictional factor and the roll gap geometry. Elastic-plastic with linear work hardening constitutive law was assumed. Asymmetric factors considered are roll diameter ratio, roll speed mismatch and differential interface friction conditions. Neutral points’ location along the contact region in relation to the &#10variations on thickness reduction, roll speed ratios, roll diameters ratio and front and back tensions are investigated. Predicted values for rolling force and torque from the present analytical model are compared with those of other workers, which are shown to be in good agreement&#10

Analysis of Rolling Process for Clad Sheet Using the Modified Slab Method

In this paper, an analytical model based on Modified Slab Method is presented for rolling of clad sheet or double-layers in which the two layers are bounded prior to rolling. This model considers the general case of asymmetrical rolling due to unequal &#10surface speed, different contact friction, roll diameters, flow stress, and thickness ratios of the two layers. Using this model, rolling par...

The Effect of Relative Deformation on the Energy-force Parameters in the Asymmetrical Plate Rolling Process

A. Kawałek, Czestochowa University of Technology, Czestochowa, Poland The paper presents the results of asymmetrical plate rolling in the finishing rolling stand of a 3600 mill. The investigation was carried out for S690Ql steel sheets. Tests were conducted for two types of the asymmetric rolling process. In the first case, the asymmetry of the process was introduced by varying the speed of the...

Comparisons of Different Models on Dynamic Recrystallization of Plate during Asymmetrical Shear Rolling

Asymmetrical shear rolling with velocity asymmetry and geometry asymmetry is beneficial to enlarge deformation and refine grain size at the center of the thick plate compared to conventional symmetrical rolling. Dynamic recrystallization (DRX) plays a vital role in grain refinement during hot deformation. Finite element models (FEM) coupled with microstructure evolution models and cellular auto...
