Book Description
This book deals with a novel and practical advanced method for control of tandem cold metal rolling processes based on the emerging state-dependent Riccati equation technique. After a short history of tandem cold rolling, various types of cold rolling processes are described. A basic mathematical model of the process is discussed, and the diverse conventional control methods are compared. A detailed treatment of the theoretical and practical aspects of the state-dependent algebraic Riccati equation technique is given, with specific details of the new procedure described and results of simulations performed to verify the control model and overall system performance with the new controller coupled to the process model included. These results and data derived from actual operating mills are compared showing the improvements in performance using the new method. Material is included which shows how the new technique can be extended to the control of a broad range of large-scale complex nonlinear processes.

Book Description
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
