The main objective of this project was to provide Cooumbus Stainless (Mpumalanga, RSA) with a numerical stimulation model that would be able to accurately predict roll forces in the roughing mill. The materials used in the model is AISI 304 stainless steel. In order to model the material flow stress accurately, uniaxial compression testing was conducted in the temperature range of 800-1250° at intervals of 50°C. The strain rates tested were 35, 10, 3.5, 1.0, 0.35, 0.1, 0.01s-1 and each temperature was tested within each strain rate. Stress curves were fitted to an equation to give stress as a function of strain, strain rate temperature. The model was constructed as a 2D, seven pass thermo-mechanical model using Abaqus Explicit version 6.2.1. The billet was modelled using 6250, 4 noded plane strain elements. The model used a basic Coulomb Friction model with a specified maximum value of friction before shearing of the billet material took place. The roller was modelled as a rigid body. 2014-07-31T11:22:16Z 2014-07-31T11:22:16Z 2001 Master Thesis Masters MSc http://hdl.handle.net/11427/5543 eng application/pdf Department of Mechanical Engineering Faculty of Engineering and the Built Environment University of Cape Town |
