When it comes to metal rolling, understanding and controlling frictional phenomena is essential to improving product and developing a more effective approach to friction reduction. Providing a historical perspective that goes as far back as the days of Leonardo da Vinci and continues up until the present day, Friction and the Hot Rolling of Steel chronicles the fundamental causes of friction. This book includes well-documented, on-site observations in various commercial plants, presents and examines practical problems, and provides a critical analysis of literary data related to the subject. It explains the base mechanisms of friction, and offers insight and instruction on improving the control and understanding of friction in hot strip mills and other industrial plants. The text presents mathematical models of friction in control and general engineering in a way that enables engineers to test and refine them in their plants. Engineers have the ability to use them to control friction and minimize its negative effects, particularly as it relates to energy waste and product defects. Organized into four sections, this book outlines the evolutional concepts of friction, and covers the general phenomena relevant to the rolling of metals. This includes the impact of roughness and velocity, basics of liquid and solid lubrication, mathematical modelling, and the properties of materials that affect friction in steel rolling, such as metals, oxides, and carbides. It connects the theoretical concepts, laboratory-scale observations, and phenomena in other areas of science and engineering to the large-scale industrial process of hot rolling. It also addresses roll properties, oxidation, wear and chemical composition of rolls and their impact on friction, the evolution of friction over schedules and roll campaigns, and mathematical modelling of friction in hot rolling. Friction and the Hot Rolling of Steel contains a large body of technical information that includes various chemical and physical properties of relevant materials, mathematical models, and plant and laboratory observations. It also provides an extensive reference list of sources that address specific problems and interests in more detail. Presents practical problems that help academics and industrial researchers to identify promising new research areas in tribology and metal processing Offers an insight into the principles of the effective research that combines both academic excellence and industrial relevance Illustrates with observations and easy-to-understand analogies, enhancing the understanding and control of the mechanisms that influence friction in industrial plants This text services technical, research, and academic personnel working in steel processing, railway engineering, rolling of other metals, solid lubrication, the automotive industry, and more.

The objective of this publication is to comprehensively discuss the possibilities of producing steels with pre-determined attributes, demanded by the customer to fit exacting specifications. The information presented in the book has been designed to indicate the reasons for the expenses and to aid in the process of overcoming the difficulties and reducing the costs. In nine detailed chapters, the authors cover topics including: • steel as a major contributor to the economic wealth of a country in terms of its capabilities and production • current concerns of major steel producers • phenomena contributing to the quality of the product • information concerning the boundary conditions of the rolling process and initial conditions, put to use by mathematical models • the solid state incremental approach and flow formulation • parameters and variables - most of which make use of the exponential nature of phenomena that are activated by thermal energy • the application of three dimensional analysis to shape rolling • the evaluation of parameters by a form of inverse analysis to the flat rolling process • knowledge based modeling, using artificial intelligence, expert systems and neural networks They conclude that when either mathematical or physical modeling of the rolling process is considered and the aim is to satisfy the demands for customers, it is possible to produce what the customer wants, exactly.

Primer on Flat Rolling is a fully revised second edition, and the outcome of over three decades of involvement with the rolling process. It is based on the author's yearly set of lectures, delivered to engineers and technologists working in the rolling metal industry. The essential and basic ideas involved in designing and analysis of the rolling process are presented. The book discusses and illustrates in detail the three components of flat rolling: the mill, the rolled metal, and their interface. New processes are also covered; flexible rolling and accumulative roll-bonding. The last chapter contains problems, with solutions that illustrate the complexities of flat rolling. New chapters include a study of hot rolling of aluminum, contributed by Prof. M. Wells; advanced applications of the finite element method, by Dr. Yuli Liu and by Dr. G. Krallics; roll design by Dr. J. B. Tiley and the history of the development of hot rolling mills, written by Mr. D. R. Adair and E. B. Intong. Engineers, technologists and students can all use this book to aid their planning and analysis of flat rolling processes. Provides clear descriptions for engineers and technologists working in steel mills Evaluates the predictive capabilities of mathematical models Assignments and their solutions are included within the text
