Analytical Modified Model of Cold Rolling Process and Investigation of the Effect of Work Roll Flattening on the Rolling Force
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...
متن کاملAnalysis of Roll Wear in Reshaping Using Finite Element Simulation
Reshaping process is a widely used method for producing tubes with non-circular cross sections. Owing to the friction between pipe and rolls, initial round pipe moves forward and consequently, it gradually formed into square or rectangular one. In practice, geometric profile of the rolls will be changed after a while. These changes would be detrimental the production of faultless products. Ther...

متن کاملFinite Element Simulation of Hot Continuous Rolling of 37Mn5 Tube Billet and Roll Pass Optimization
In order to optimize the continuous rolling schedule for improving the quality of rolled tube billet, three dimensional thermal mechanical coupled finite element simulation is applied to analyse the multi-pass continuous rolling process of Ф100mm 37Mn5 steel tube billet from 200mm×200mm square cast bloom. Due to the larger plastic strain occurring at the corner area of the billet, the bias mesh...
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...
