Abstract
Steelmaking industry is changing in recent years to become greener and less energy consuming. Beside improvements on equipment, advanced numerical tools provide perspectives on design of the production process in order to reduce scraps, material usage and energy consumption and improve the overall quality of the products. In this paper, the journey of a metal from the furnace heating to the rolling will be presented. Several topics will be investigated by means of simulation: a new model developed to predict the oxide scale thickness and mass formed on steel during high temperature processes. It is available for oxide scale growth on pure iron and low-alloyed steels, including two growth mechanisms. Oxide scale spalling prediction due to deformation based on shear stress at metal / oxide interface will be investigated, together with the variation of thermal boundary conditions and metal emissivity due to oxide scale formation. The thermo-mechanical-metallurgical coupling used during rolling process with two cutting-edge approaches: a time-saving steady-state approach for rolling simulations and a Lagrangian approach to predict most anticipated results: shape evolution, product/roll contact area, temperature evolution, influence of the roll geometry in each section, forces and torques applied on the rolls, strain evolution and profiles, deformation level.
