The Modelling of Cold Rolling by FEM Analyses

Popis výsledku v původním jazyce

In this article, results from the FEM-analyses of strips cold rolling are described. The FEM-analyses were carried out in DEFORM 3D software. FEM-model for a cold rolling process with front and back tension was developed. To describe material behaviour of nickel alloys (NiCrFe, FeNi42 and FeNi47Cu5) in the FEM-analyses, the specific material model was proposed. This material model combines the material data obtained from Rastegaev compression test and the results of thermodynamical calculation from JMatPro software. Rolling parameters for the strip thickness reduction were set in accordance with the real process conditions. During the computation of each roll pass the strip thickness was sequentially reduced from 8 to 0.8 mm. Once the strip thickness reached 2.5 mm in the cross section area an annealing operation was performed. The main results of performed FEM-analyses were the increase of strain, damage and temperature in the strip during each roll pass, as well as rolling force. The
