Flat Rolling FundamentalsThis volume compiles information from physics, metallurgy, and mechanical and electrical engineering to epitomize the fundamental characteristics of flat rolling steel. Flat Rolling Fundamentals is drawn from in-depth analyses of metal properties and behaviors to technologies in application. The book provides a full characterization of steel, including structure, chemical composition, classifications, physical properties, deformation, and plasticity. The authors present different types of rolling mills and the defining physical analytical parameters.They also discuss the effects of hot rolling on steel and the role of lubrication and thermomechanical treatments to minimize these effects. This book presents qualitative and quantitative advances in cost-effective steel production. |
