Thermal-Mechanical Modelling of the Flat Rolling Process [Paperback]

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.Flat rolling is considered to be one of the most important and most widely used metal forming processes.
