Thermal-Mechanical Modelling of the Flat Rolling Process

• Broschiertes Buch

Produktbeschreibung

Flat rolling is considered to be one of the most important and most widely used metal forming processes. This book emphasizes the importance of mathematical simulation of this process in the light of the ever in- creasing need for quality improvements through automation. Mathematical models of the hot, warm and cold rolling processes are discussed, compared and critically evaluated. Engineers in the steel industry will find this book particularly useful in their everyday work.

Autorenporträt

Thermal-mechanical modelling of hot, warm and cold rolling is presented. The dependence of the accuracy and consistency of the predictions on the boundary conditions - heat transfer and friction - and on the initial conditions - The resistance of the material to deformation - is discussed.
