Book Synopsis Mathematical models for temperature distribution in slab (strip), work rolls and for thermal crown of work rolls during hot flat rolling by : Peter Fajfar
Download or read book Mathematical models for temperature distribution in slab (strip), work rolls and for thermal crown of work rolls during hot flat rolling written by Peter Fajfar and published by . This book was released on 1992 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of cross-sectional temperature in slab (strip), work rolls and thermal crown of work rolls during hot flat rolling is investigated. For solving the Fourier differential equation for two-dimensional transient heat conduction with internal heat source a simple implicite finite difference method is used. The mathematical model for temperature evolution in slab is tested by comparing its predictions of surface temperature to measured ones of industrial hot flat rolling of aluminium on two-high reversing rolling mill.
Book Synopsis Thermal-Mechanical Modelling of the Flat Rolling Process by : Maciej Pietrzyk
Download or read book Thermal-Mechanical Modelling of the Flat Rolling Process written by Maciej Pietrzyk and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Mathematical and Physical Simulation of the Properties of Hot Rolled Products by : Maciej Pietrzyk
Download or read book Mathematical and Physical Simulation of the Properties of Hot Rolled Products written by Maciej Pietrzyk and published by Elsevier. This book was released on 1999-07-05 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Primer on Flat Rolling by : John G. Lenard
Download or read book Primer on Flat Rolling written by John G. Lenard and published by Newnes. This book was released on 2013-12-04 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Book Synopsis Thermal Fatigue of High Chromium Steel Rolls by : Gerard Valverde Montraveta
Download or read book Thermal Fatigue of High Chromium Steel Rolls written by Gerard Valverde Montraveta and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the master work the phenomenon of appearance of firecracks on the surface of the work rolls that occur during hot rolling of flat products in the case of regular rolling conditions and in the case of the rolling mill stalls was investigated. During hot rolling work rolls are subjected to successive heating and cooling conditions. Their surface is exposed to rapid temperature changes due to the contact with hot rolled material and due to cold water used for rolls cooling. These cyclic heating/cooling conditions cause thermal fatigue which is one of the most important factors affecting the rate of surface deterioration as well as mechanical fatigue and abrasion. Two different tests for the laboratory assessments of the thermal fatigue resistance of the high-chromium steel rolls were used. The first test enables a simulation of the work roll thermal fatigue in the case of regular rolling conditions. Furthermore, with the second test thermal fatigue of work rolls in the case of the rolling mill stalls was investigated. Both tests were implemented in a thermo-mechanical simulator of metallurgical states, the Gleeble 1500D. Finite elements method simulations were performed to determinate the temperature distribution in the work rolls by using NSC.SuperForm software. Evident dependence of the crack nucleation and their growth with the temperature and the cooling medium was found but no dependence due to the length of contact time was found. The influence of slab thickness and slab initial temperature to the temperature evolution in the surface layer of the work roll was estimated. The master work contributes to better understanding of crack nucleation and their growth during the usual hot rolling conditions, as well as for the case of rolling mill stalls.
