Book Synopsis Contribution à l'étude de la lubrification en régime mixte en laminage by : Stephany Antoine
Download or read book Contribution à l'étude de la lubrification en régime mixte en laminage written by Stephany Antoine and published by Presses Academiques Francophones. This book was released on 2015-08-10 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accelerer la cadence des unites en activite requiert une meilleure comprehension, et donc maitrise, des procedes industriels. En parallele, l'optimisation de ces procedes permet de gagner en cout de fonctionnement et en qualite du produit fourni. L'acceleration, l'optimisation et l'evolution de l'operation de laminage a froid peuvent etre aides par un outil informatique performant, ce qui est l'objet de ce travail. La problematique du laminage a froid implique de nombreux mecanismes complexes dont un parametre crucial est la friction entre les cylindres et la bande. La lubrification est un agent efficace du procede industriel mais ses mecanismes intimes restent encore relativement mal connus. L'industrie exige un regime de lubrification mixte qui permet un compromis entre qualite de produit et vitesse de production. Les surfaces rugueuses du cylindre et de la bande sont alors en contact avec de nombreux micro contacts directs et micro vallees lubrifiees. La theorie classique du laminage modelise une passe de laminage a froid. La presence des rugosites et du lubrifiant ont ete introduites par la suite pour finalement aboutir au premier modele de regime mixte de Wilson..."

Available in PDF, EPUB and Kindle. Book excerpt: This publication has been written to honour the contribution to science and education made by the Distinguished Professor Emeritus Professor Schey on his eightieth birthday. The contributors to his book are among the countless researchers who have read, studied and learned from Professor Schey's work, which includes books, research monographs, invited papers, keynote papers, scientific journals and conferences. The topics include manufacturing, sheet and bulk metal forming and tribology, amongst others. The topics included in this book include: John Schey and value-added manufacturing; Surface finish and friction in cold-metal rolling; Direct observation of interface for tribology in metal forming; An examination of the coefficient of friction; Studies on micro plasto hydrodynamic lubrication in metal forming; Numerical simulation of sheet metal forming; Geometric and mechanics model of sheet forming; Modelling and optimisation of metal forming processes; The mathematical modelling of hot rolling steel; Identification of rheological and tribological parameters; Oxide behaviour in hot rolling; Friction, lubrication and surface response in wire drawing; and Modelling and control of temper rolling and skin pass rolling.
Book Synopsis Oxide Scale Behavior in High Temperature Metal Processing by : Michal Krzyzanowski
Download or read book Oxide Scale Behavior in High Temperature Metal Processing written by Michal Krzyzanowski and published by John Wiley & Sons. This book was released on 2010-03-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: The result of a fruitful, on-going collaboration between academia and industry, this book reviews recent advances in research on oxide scale behavior in high-temperature forming processes. Presenting novel, previously neglected approaches, the authors emphasize the pivotal role of reproducible experiments to elucidate the oxide scale properties and develop quantitative models with predictive accuracy. Each chapter consists of a detailed, systematic examination of different aspects of oxide scale formation with immediate impact for researchers and developers in industry. The clear and stringent style of presentation makes this monograph both coherent and easily readable.
Download or read book Cold Rolling of Steel written by Roberts and published by Routledge. This book was released on 2017-11-22 with total page 822 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the publication of this book, newcomers to the field of steel rolling have a complete introductionto the cold rolling process, including the history of cold rolling, the equipment currentlyin use, the behavior of the rolling lubricant, the thermal and metallurgical aspects of the subject,mathematical models relating to rolling force and power requirements, strip shape, and thefurth er processing of cold-rolled steel. The first book in print to examine in detail the three componentsof the cold-rolling process- the mill, the work-piece, and the rolling lubricant-this bookcan be used as a training manual and as a source for reference and research. The manuscript version of this book has already been in use as a textbookin courses on cold rolling and rolling lubrication and is now published for thebenefit of all in-training personnel-both operating and supervisory-in theprimary metals industry and for undergraduate and graduate students inmetalworking. The interrelationships of the three components, described in terms ofmathematical models, are of considerable value to engineers associated withprimary metals and metal research, to mill builders, and to electrical equipmentsuppliers. For plant metallurgists, the book relates product quality to operating conditions;for the steel user and purchaser, it affords insight into the variousprocesses associated with the manufacture of steel sheet and strip.

Book Synopsis Historical Dictionary of Pakistan by : Shahid Javed Burki
Download or read book Historical Dictionary of Pakistan written by Shahid Javed Burki and published by . This book was released on 1999 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pakistan is unlike most other countries in the emerging world. It is one of the two nations – the other being the state of Israel – founded on the basis of religion. Although it was created to provide a homeland for the Muslim community of British India, in its original form it was able to accommodate only about half of the people of Islamic faith who lived in the subcontinent. Pakistan’s birth in 1947 resulted in one of the largest movements of people in human history when some 14 million people left their homes, with 8 million Muslims leaving India for what is now Pakistan and 6 million Hindus and Sikhs moving in the opposite direction. This was the first large-scale incidence of ethnic cleansing the world was to witness. --
