SKIN-PASS PROCESS ANALYSIS THROUGH FINITE ELEMENT MODELS

Abstract

The skin-pass is a cold-rolling process located at the final stage of the steel strip manufacturing line. Its main objective is to modify the strip material properties and its surface structure to be the suited for the post forming operations as deformations, welding and painting. This work is focused on the analysis of the Skin-pass process through Finite Element Models (FEM) in order to obtain the influence of the parameters involved. In this way would be possible to establish optimization criterions for the process. The modeling of the skin-pass is somehow a challenger as there are important factors as: highly localized deformations; non-circular work-roll behaviour and elasto-plastic characteristics on the rollgap area, difficult to model. The software used to model the process was ABAQUS®. Keywords: Skin pass, finite element modelin, steel manufacturing process.
