Book Description
This book provides a fascinating study of the very important emerging field of direct reduction in which iron ore is ‘directly reduced’ in the solid-state, using either natural gas or non-coking coal, to produce a highly metallised material, referred to as sponge iron (or direct reduced iron). This intermediate product is subsequently melted in electric arc furnaces or induction furnaces (sometimes even in basic oxygen furnaces) to produce liquid steel. Such a process combination enables steel to be produced without using coking coal, which is an expensive input in the normal blast furnace—basic oxygen furnace route of steelmaking adopted in integrated steel plants. The book offers comprehensive coverage and critical assessment of various coal-based and gas-based direct reduction processes. Besides dealing with the application of the theoretical principles involved in the thermodynamics and kinetics of direct reduction, the book also contains some worked-out examples on sponge iron production. The concluding part of this seminal book summarises the present and future scenario of direct reduction, including the use of gas generated from coal in direct reduction processes. The book is primarily intended for the undergraduate and postgraduate students of metallurgical engineering. It is also a must-read for researchers, technologists and process metallurgists engaged in the rapidly developing field of direct reduction of iron oxides, which is of critical importance for India and other developing nations that are beginning to play a major role in global steelmaking.

Book Description
With a boom in the steel industry all over the world today, the demand of sponge iron has considerably increased as a feed (raw) material to steel making. The increase in the demand of sponge iron is also due to the fact that it is used for replacing coke making required for blast furnace processing. The primary objective of this book is to provide the basis, principles, fundamentals and theory of sponge iron production. This book, earlier titled as Sponge Iron Production in Rotary Kiln, is revised as per the feedback from students, faculty members and professionals. It, now, covers broad spectrum of alternative routes of iron making, therefore, the book is renamed as Alternative Routes to Iron Making. In this revised edition of the book, three new chapters have been added to fulfil the requirement of a textbook for various universities. NEW TO THIS EDITION • New chapters on: o Utilization of Sponge Iron o Environmental Pollution and Control in Sponge Iron Industries o Smelting Reduction Process • Inclusion of principle of fluidisation in fluidised bed processes • Description of Hyl III process with recent development of the process Primarily intended for undergraduate and postgraduate students of metal-lurgical engineering, this book is equally beneficial for researchers, and professionals engaged in DR processes and steel industries.

Book Description
Annotation About the Book: Now that India is virtually the only player in this field, an elaboration is needed with respect to more fundamental understanding as well as future prospects and needs, which this edition has tried to fulfill. It can now fulfill the need of a reference textbook in alternate iron making area for undergraduate and post graduate students in Metallurgical, Production, Manufacturing, Chemical, Materials and to a minor extent Mechanical Engineering disciplines. The aim of fulfilling the needs of entrepreneurs and plant operators has not only been retained; it has been elaborated. Further, the basic aspects have been presented in a way that is lucid and simple to understand and should serve as an incentive to the operators and entrepreneurs to develop a deeper understanding of the process. The project engineering section now gives guidelines sufficient to make a project report. Opportunities available to this process and the competition it faces has also been highlighted. A chapter on reaction kinetics has been included as also a section on iron ore and pellets. Other sections included are on Aerodynamics, Auto Ignition, Coal Throwing, etc. Rest of the text has been updated to the extent possible. Some advanced features have been introduced such as Mathematical Modeling, Computational Fluid Dynamics, Reduction Mechanism, etc. to give researchers in the area of food for thought.

Book Description
This authoritative account covers the entire spectrum from iron ore to finished steel. It begins by tracing the history of iron and steel production, right from the earlier days to today’s world of oxygen steelmaking, electric steelmaking, secondary steelmaking and continuous casting. The physicochemical fundamental concepts of chemical equilibrium, activity-composition relationships, and structure-properties of molten metals are introduced before going into details of transport phenomena, i.e. kinetics, mixing and mass transfer in ironmaking and steelmaking pro-cesses. Particular emphasis is laid on the understanding of the fundamental principles of the processes and their application to the optimisation of actual processes. Modern developments in blast furnaces, including modelling and process control are discussed along with an introduction to the alternative methods of ironmaking. In the area of steelmaking, BOF plant practice including pre-treatment of hot metal, metallurgical features of oxygen steelmaking processes, and their control form part of the book. It also covers basic open hearth, electric arc furnace and stainless steelmaking, before discussing the area of casting of liquid steel—ingot casting, continuous casting and near net shape casting. The book concludes with a chapter on the status of the ironmaking and steelmaking in India. In line with the application of theoretical principles, several worked-out examples dealing with fundamental principles as applied to actual plant situations are presented. The book is primarily intended for undergraduate and postgraduate students of metallurgical engineering. It would also be immensely useful to researchers in the area of iron and steel.
