Finite element method analysis of surface roughness transfer in micro flexible rolling
Micro flexible rolling aims to fabricate submillimeter thick strips with varying thickness profile, where the surface quality of products is mainly determined by initial workpiece surface roughness and subsequent surface asperity flattening process, which is affected by process parameters during rolling. This paper shows a 3D finite element model for flexible rolling of a 250 μm thick workpiece...
متن کاملDevelopment of a Predictive Finite Element Model For Investigation of Phases Behavior After Cold Rolling Process
One of the surface defects that arise in sheet metal working is when the part removes from the die. Since there are no external forces to make this defect, the origin of such fail is known as residual stress. Residual stress can develop in sheet metal forming due to non uniform deformation. In this paper, the workpiece is carbon steel with different volume fractions and arrangement of ferrite ...
متن کاملA Roll Wear Prediction Model in Hot Plate Rolling
In this paper, the wear of work roll in hot plate rolling is introduced and the parameters affecting wear mechanisms in hot strip mill are investigated. In addition, different wear mechanisms in hot rolling and the differences between these mechanisms in different stands are explained. Using the finite element method and the rolling equations, a work roll wear model is proposed. Wear is modeled...
متن کاملUsing Experimental Procedure to Improve the Efficiency of the Two Stand Reversing Cold Mill
Production of thin steel strips with 0.18-0.26 mm thickness is about 0.75 of annual production of the two stand reversing cold mill, while its efficiency is 60%. This is due to the fact that after montaging the grinded work rolls, rolling thin steel strips (with thicknesses less than 0.18 millimeters) is unavailable. Initially, unsuitable surface roughness, the friction between rolls and the st...
