Contributed articles presented in the International Conference on Advances in the Theory of Ironmaking and Steelmaking; organized by the Dept. of Material Engineering, IISc., Bangalore.

This book describes improvements in the iron and steel making process in the past few decades. It also presents new and improved solutions to producing high quality products with low greenhouse emissions. In addition, it examines legislative regulations regarding greenhouse emissions all around the world and how to control these dangerous emissions in iron and steel making plants.

​This book describes the available technologies that can be employed to reduce energy consumption and greenhouse emissions in the steel- and ironmaking industries. Ironmaking and steelmaking are some of the largest emitters of carbon dioxide (over 2Gt per year) and have some of the highest energy demand (25 EJ per year) among all industries; to help mitigate this problem, the book examines how changes can be made in energy efficiency, including energy consumption optimization, online monitoring, and energy audits. Due to negligible regulations and unparalleled growth in these industries during the past 15-20 years, knowledge of best practices and innovative technologies for greenhouse gas remediation is paramount, and something this book addresses. Presents the most recent technological solutions in productivity analyses and dangerous emissions control and reduction in steelmaking plants; Examines the energy saving and emissions abatement efficiency for potential solutions to emission control and reduction in steelmaking plants; Discusses the application of the results of research conducted over the last ten years at universities, research centers, and industrial institutions.

Laser cladding is an additive manufacturing technology capable of producing coatings due to the surface fusion of metals. The selected powder is fed into a focused laser beam to be melted and deposited as coating. This allows to apply material in a selected way onto those required sections of complex components. The process main properties are the production of a perfect metallurgically bonded and fully dense coatings; the minimal heat affected zone and low dilution between the substrate and filler material resulting in functional coatings that perform at reduced thickness, so fewer layers are applied; fine, homogeneous microstructure resulting from the rapid solidification rate that promotes wear resistance of carbide coatings; near net-shape weld build-up requires little finishing effort; extended weldability of sensitive materials like carbon-rich steels or nickel-based superalloys that are difficult or even impossible to weld using conventional welding processes; post-weld heat treatment is often eliminated as the small heat affected zone minimizes component stress; excellent process stability and reproducibility because it is numerical controlled welding process. The typical applications are the dimensional restoration; the wear and corrosion protection; additive manufacturing. The wide range of materials that can be deposited and its suitability for treating small areas make laser cladding particularly appropriate to tailor surface properties to local service requirements and it opens up a new perspective for surface engineered materials. The main key aspect to be scientifically and technologically explored are the type of laser; the powders properties; the processing parameters; the consequent microstructural and mechanical properties of the processed material; the capability of fabrication of prototypes to rapid tooling and rapid manufacturing. Distills critical concepts, methods, and applications from leading full-length chapters, along with the authors’s own deep understanding of the material taught, into a concise yet rigorous graduate and advanced undergraduate text; Reinforces concepts covered with detailed solutions to illuminating and challenging industrial applications; Discusses current and future applications of laser cladding in additive manufacturing.

This book addresses various issues pertaining to engineering education in India. One of the mandates of the Indian National Academy of Engineering, an apex body of distinguished engineers and scientists, is to set up tracks for the countrymen for achieving excellence in engineering education. This book aims to identify such tracks. The obligations and rights of the stake holders and the government vis--vis engineering education are also discussed at length. The present engineering education and the skills it imparts to students are inadequate to meet new and emerging challenges of equality of capabilities which is required for international mobility in the WTO environment. Since India is not yet a member of the Engineers Mobility Forum and only a provisional member of the Washington Accord at present, recognition of our Engineering degrees abroad is not automatic. Of course, due to their generally recognized brand names, the degrees from IITs and many other prominent engineering institutions in the country are readily recognized in most countries. Steps are presently being taken by the National Board of Accreditation of AICTE to obtain full membership of the Washington Accord. Re-engineering the engineering education to achieve excellence and sustain it thus an important objective. This book represents a systematic analysis highlighting the issues related to this objective. The book is the outcome of an INAE-sponsored research study that examines the challenges faced by engineering education in terms of access, equity, regional imbalance and quality. The study is also aimed at analyzing the weaknesses of the present system and identifying the requirements of the modern teaching-learning processes. The study suggests measures for improvement in faculty qualifications and competence, and finally, it provides some insight for instituting healthy academic governance.

From the prediction of complex weather patterns to the design of swimsuits, modeling has, over the years, quietly but steadily become an essential part of almost every field and industry-and steelmaking is no exception. Factors such as visual opacity, high operating temperature, and the relatively large size of industrial reactors often preclude di

Progress in our knowledge of thermodynamics and physico-chemical factors in manganese ferroalloy production has developed rapidly during the past twenty-five years or so. The authors' intention has been to use this basic knowledge in discussions of industrial manganese ferroalloy production. The book presents the principles and current knowledge of processes in the production of high carbon ferromanganese, silicomanganese and low carbon manganese alloys. The book is intended for professionals working in production, plant design or development. It will also be useful for researchers in industry, universities and research institutes. The book can be used as a textbook for courses in extractive and process metallurgy, and for company in-house courses. Thermodynamics of the slag and metal systems are extensively covered. Computational modelling based on assessed thermochemical databases has made it possible to calculate and present a large number of phase and equilibrium diagrams. These diagrams are useful for easy understanding and analysis of the complex heterogeneous equilibria in the manganese ferroalloy metallurgy. The manganese ferroalloys are mainly produced in electric submerged arc furnaces. Electrical relations are briefly discussed. Supply of raw materials, especially manganese ores and coke, is extremely important for the manganese industry. The book gives the reader appropriate knowledge regarding the selection the best of available raw materials. Environmental issues, including greenhouse gas emissions and climate changes, are of growing concern to ferroalloy producers. Carbon will always be needed as a reducing agent, and consequently emission of CO2 gas is inevitable. The book describes solutions to dealing with pollution problems and gives the latest guidelines for greenhouse gas inventories.
