Abstract A mathematical model of a striplooper system of a hot strip tandem rolling mill is developed using Hamilton's principle and the Galerkin weighted residual method. Several nonlinearities are considered and the effects of bending and dynamic forces on the accuracy of the model are studied. Based on the model, an estimator for the strip tension is proposed. Finally, an impedance ...

Rolling of soft metals like gold, silver and perhaps lead was first performed by goldsmiths for making jewelry. Hand driven rolls of about ½ inches ( mm) in diameter were in use during the fourteenth century. However, the concept of a true rolling mill is first found as a sketch in the notebook of Leonardo da Vinci.
