The Analysis of the Cold Flat Rolling Process by Salf Program

Abstract

SALF program is a Brazilian program developed to simulate the cold flat rolling process by the finite element method. The program uses the implicit and rigid-plastic approaches to perform numerical analyses. This article presents the cold flat rolling simulations performed by SALF, where the variables of rolling force, effective strain rate, and effective strain were analyzed. The simulations were chosen from the literature and involved materials such as steel and aluminum, with thicknesses of 1.0 mm and 3.0 mm, reductions of 5%, 16.67%, and 30%, and friction coefficients of 0.08, 0.1, and 0.3. The results showed that SALF describes the above variables appropriately in qualitative and quantitative terms. However, based on the research results, domestic steel industries may now use a national program to simulate the cold flat rolling process to improve their processes and products.
