Available in PDF, EPUB and Kindle. Book excerpt: Tandem Hot Metal Rolling Mill Control is a response to the significant control engineering challenges posed by the nature and circumstances of the hot metal strip rolling process. The process is large, complex, multivariable and nonlinear with significant disturbances and subject to multiple situationally dependent time delays all of which are exacerbated by the demands of an ever-more-competitive marketing environment for its product. The book provides innovative solutions not available with previously existing methods of control. It introduces new advanced control methods, including a nonlinear control method based on an advanced state-dependent Riccati equation technique coupled with virtual rolling to improve performance during various regimes of mill operation. The book begins with a brief history of metal rolling and an overview of the tandem hot metal rolling process. It then discusses process models, including physical-system and state-space equations, and control methods currently being used in tandem rolling. The exposition of the new advanced control method uses figures and simulations to facilitate thorough understanding of the methods and their applicability in the real world. The final chapter concludes with a brief discussion of variable-speed drives as typically used in modern installations. Although sufficient mathematical treatment is provided to support the development of novel concepts, the presentation is not highly mathematical, making the text readily understandable and useful to a variety of readers in both academic and practical engineering milieux.

Download or read book Process Control for Sheet Metal Stamping written by Yongseob Lim and published by Springer Science & Business Media. This book was released on 2013-12-12 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Process Control for Sheet-Metal Stamping presents a comprehensive and structured approach to the design and implementation of controllers for the sheet metal stamping process. The use of process control for sheet-metal stamping greatly reduces defects in deep-drawn parts and can also yield large material savings from reduced scrap. Sheet-metal forming is a complex process and most often characterized by partial differential equations that are numerically solved using finite-element techniques. In this book, twenty years of academic research are reviewed and the resulting technology transitioned to the industrial environment. The sheet-metal stamping process is modeled in a manner suitable for multiple-input multiple-output control system design, with commercially available sensors and actuators. These models are then used to design adaptive controllers and real-time controller implementation is discussed. Finally, experimental results from actual shop floor deployment are presented along with ideas for further improvement of the technology. Process Control for Sheet-Metal Stamping allows the reader to design and implement process controllers in a typical manufacturing environment by retrofitting standard hydraulic or mechanical stamping presses and as such will be of interest to practising engineers working in metal-working, automotive and aeronautical industries. Academic researchers studying improvements in process control and how these affect the industries in which they are applied will also find the text of value.

This book was released on 2010-01-01 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hot rolling technology is the most widely used method of shaping metals and is particularly important in the manufacture of steel for use in construction and other industries. In metalworking, rolling is a metal forming process in which metal stock is passed through a pair of rolls. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its re crystallization temperature, then the process is termed as hot rolling. The hot mills using plain rolls were already being employed by the end of the seventeenth century. But the industrial revolution in the nineteenth century saw a new horizon in steel making process, with the considerably expanded markets for rods, rails and structural section, provided further impetus to the development of hot rolling. The basic use of hot rolling mills is to shape up the larger pieces of billets and slabs into narrow and desired forms. These metal pieces are heated over their re crystallization temperature and are then moved between the rollers so as to form thinner cross sections. Hot rolling mill thus helps in reducing the size of a metal thereby molding it into the desired form and shape. Rolling mills perform the function to reform the metal pieces such as billet and ingot whilst maintaining its well equipped micro structure into bar, wire, sheet, strip, and plate. Hot rolled products are frequently categorized into plain carbon, alloy, high strength alloy, dual phase, electrical and stainless steels. This book provides a descriptive illustration of pre treatment of hot metal, the basic principles of heat treatment, types of hot rolled products, principles of measurement of rolling parameters, steel making refractories, performance characteristics of transducers, causes of gauge variation , main factors affecting gauge performance, gauge control sensors and actuators, automatic gauge control systems, strip tension control system in cold mills, flat rolling practice cold rolling, pack rolling, steelmaking refractories, refining of stainless steels, special considerations in refining stainless steels etc. This book is a unique compilation and it draws together in a single source technical principles of steel making by hot rolling process up to the finished product. This handbook will be very helpful to its readers who are just beginners in this field and will also find useful for upcoming entrepreneurs, engineers, personnel responsible for the operation of hot rolling mills, existing industries, technologist, technical institution etc. TAGS Steel Hot Rolling, Hot Rolling of Steel, Metal Rolling, Metal Forming Process, Steel Rolling Process, Metalworking, Flat Rolling Fundamentals, Physical Metallurgy, Hot Rolled Steel, Rolling Mills, Pre-Treatment of Hot Metal, Heat Treatments for Hot-Rolled Products, Steelmaking Refractories, Refining of Stainless Steels, Steel Heating for Hot Rolling, Oxygen Steelmaking Processes, Best small and cottage scale industries, Business guidance for steel rolling industry, Business Plan for a Startup Business, Business plan for steel rolling mill, Business start-up, Fusion welding processes, Great Opportunity for Startup, Hot rolled steel properties, Hot rolling mill process, Hot Rolling Mill, Hot Rolling mill, Hot Strip Mill, How is Steel Produced, How to Start a Steel Production Business, How to start a successful steel rolling business, How to start steel mill industry, How to Start Steel rolling Industry in India, How to start steel rolling mill, Indian Steel Industry, Industrial steel rolling mill, Modern small and cottage scale industries, Modern steel making technology, Most Profitable Steel Business Ideas, New small scale ideas in Steel rolling industry, Opportunity Steel Rolling Mill, Plate Mill, Process & Applications, Process of steelmaking, Profitable small and cottage scale industries, Progress and Prospect of Rolling Technology, Project for startups, Rod and Bar Rolling, Rod and bar rolling, Rolling Metalworking, Rolling Mill for Steel Bars, Rolling process, Setting up and opening your steel rolling Business, Small scale Commercial steel rolling business, Small Scale Steel rolling Projects, Small Start-up Business Project, Start a Rolling Mill Industry, Start steel rolling mill in India, Start up India, Stand up India, Starting a Steel Business, Starting a Steel rolling Business, Starting Steel Mini Mill, Start-up Business Plan for steel rolling, Startup Project for steel rolling business, Startup project plan, Startup Project, Steel and hot rolling Business, Steel Based Profitable Projects, Steel Based Small Scale Industries Projects, Steel business plan, Steel hot rolling process, Steel Industry in India, Steel making and rolling, Steel making Projects, Steel making technology, Steel Making, Steel manufacturing process, Steel mill process, Steel mill, Steel production process, Steel rerolling mill feasibility start up, Steel rolling Industry in India, Steel rolling machine factory, Steel rolling mill industry demand, Steel rolling mill industry overview, Steel rolling mill industry, Steel rolling mill market forecast, Steel rolling mill market growth, Steel rolling mill market, Steel rolling mill size, Steel rolling mill starts production, Steel rolling mill, Steel Rolling Technology, Steelmaking, Steelmaking Processes, Types of rolling mills

Download or read book Electrical Drive Simulation with MATLAB Simulink written by Viktor Perelmuter and published by CRC Press. This book was released on 2024-04-26 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chapters of this book discuss the modeling of electric drives, taking into account their relationship with the technological process they serve, which significantly affects the composition, layout, and characteristics of the electric drive. There are no published books of this kind, and this book fills a gap in the literature. This book deals with electric drives for rolling mills, paper machines, a number of several hoisting and transport devices; these installations are very common and very complex, so that modeling methods in their development and study are mandatory. The book focuses on issues such as the transmission of torque by elastic shafts, the transmission of torque by an endless elastic belt in paper machines and conveyors, the transmission of torque by friction of pressed rolls in the paper industry, the consideration of the elastic properties of long ropes in some hoisting and transport machines, and the effect of swinging a moving load in such machines. More than 100 models of the electrical drives that are made with the use of the program environment MATLAB®/Simulink® are appended to this book. The aims of these models are to aid students studying electrical drives of the various manufacturing machines, to facilitate the understanding of various electrical drive functions, and to create a platform for the development of systems by readers in their fields. This book can be used by engineers and investigators as well as undergraduate and graduate students to develop new electrical drives and investigate the existing ones.

This book was released on 2010-12-02 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Symposium was aimed at the theoretical and numerical problems involved in modelling the dynamic response of structures which have uncertain properties due to variability in the manufacturing and assembly process, with automotive and aerospace structures forming prime examples. It is well known that the difficulty in predicting the response statistics of such structures is immense, due to the complexity of the structure, the large number of variables which might be uncertain, and the inevitable lack of data regarding the statistical distribution of these variables. The Symposium participants presented the latest thinking in this very active research area, and novel techniques were presented covering the full frequency spectrum of low, mid, and high frequency vibration problems. It was demonstrated that for high frequency vibrations the response statistics can saturate and become independent of the detailed distribution of the uncertain system parameters. A number of presentations exploited this physical behaviour by using and extending methods originally developed in both phenomenological thermodynamics and in the fields of quantum mechanics and random matrix theory. For low frequency vibrations a number of presentations focussed on parametric uncertainty modelling (for example, probabilistic models, interval analysis, and fuzzy descriptions) and on methods of propagating this uncertainty through a large dynamic model in an effi cient way. At mid frequencies the problem is mixed, and various hybrid schemes were proposed. It is clear that a comprehensive solution to the problem of predicting the vibration response of uncertain structures across the whole frequency range requires expertise across a wide range of areas (including probabilistic and non-probabilistic methods, interval and info-gap analysis, statistical energy analysis, statistical thermodynamics, random wave approaches, and large scale computations) and this IUTAM symposium presented a unique opportunity to bring together outstanding international experts in these fields.
