Cold rolling of steel is one of the most important metal forming processes so an accurate control of its parameters during the process is necessary. In this paper, the friction coefficient has been proposed as a function of cold rolling parameters such as forward slip, forward and backward tensile stresses ,strip thickness, static deformation, resistance of strip before and after rolling ,strip...

The defect in work rolls directly influence the forming cost and the final shape of the product. The researchers tend to investigate the thermo-mechanical stress in work roll of rolling machines. These stresses may reduce the roll life. Since the investigation of the thermo-mechanical stress in work roll with real-conditions is complex, comprehensive studies by means of numerical methods are av...

Abstract The presented paper provides a modelling strategy for roll forming of high strength AA7075 aluminum tube. Roll allows the cost-effective production large quantities long profiles. Forming brings challenges like springback and poor formability due to low Young’s modulus, ductility yield strength. processes with aluminum, such as alloy, therefore require detailed process design. Three di...
