This book details the peculiarities of the requirements for refractories designed for aluminium metallurgical process: reduction, cast house, and anode production. The author describes requirements specific to the properties and structure of refractory materials that differentiate it from the refractories for ferrous metallurgy and other refractories. A comparison is drawn between the properties and structure of refractories and carbon cathode materials from different points of view: from the point of physical chemistry and chemistry interactions during the metallurgical process and from the point of design of reduction pots and furnaces with the aspect to the service life time of metallurgical aggregates.
This book details the rigorous requirements for refractories designed for aluminium metallurgical processes: reduction, cast house, and anode production. The author describes requirements specific to the properties and structure of refractory materials that differentiate it from materials used for ferrous metallurgy, among others. A comparison is drawn between the properties and structure of refractories and carbon cathode materials from different points of view: from the perspective of physical chemistry and chemical interactions during the metallurgical process and from the aspect of designing reduction pots and furnaces to accommodate the lifetime of metallurgical aggregates that are a part of aluminum refractory processes.
The Light Metals symposia are a key part of the TMS Annual Meeting & Exhibition, presenting the most recent developments, discoveries, and practices in primary aluminum science and technology. Publishing the proceedings from these important symposia, the Light Metals volume has become the definitive reference in the field of aluminum production and related light metal technologies. The 2016 collection includes papers from the following symposia: 1.Alumina and Bauxite 2.Aluminum Alloys, Processing, and Characterization 3.Aluminum Reduction Technology 4.Cast Shop Technology 5.Electrode Technology 6.Strip Casting
This book promotes understanding of the raw material selection, refractory design, tailor-made refractory developments, refractory properties, and methods of application. It provides a complete analysis of modern iron and steel refractories. It describes the daily demands on modern refractories and describes how these needs can be addressed or improved upon to help achieve the cleanest and largest yields of iron and steel. The text contains end-of-chapter summaries to help reinforce difficult concepts. It also includes problems at the end of chapters to confirm the reader's understanding of topics such as hoop stress modeling in steel ladle and vessels, establishment of thermal gradient modeling , refractory corrosion dynamics, calculation of Blast furnace trough dimension based on thermal modeling, to name a few. Led by editors with backgrounds in both academia and industry, this book can be used in college courses, as a reference for industry professionals, and as an introduction to the technology for those making the transition to industry. Stands as a comprehensive introduction to the science and technology of modern steel and iron-making refractories that examines the processes, construction, and potential improvement of refractory performance and sustainability; Serves as a versatile resource appropriate for all levels, from the student to industry novices to professionals; Reinforces difficult-to-grasp concepts with end-of-chapter summaries; Maximizes reader understanding of key topics, such as refractory selection for steel ladle and vessels, and their corrosion dynamics, with real life problems.

This book emphasizes the underlying metallurgical principles of casting technology so that the students can develop a sound set of analytical skills helpful in the development of improved casting processes and products. Besides comprehensive coverage of the casting processes and elaborate discussion of properties of cast irons, cast steels, and cast non-ferrous alloys, the book also familiarizes the students with the most recent developments in binder systems, casting practices, solidification processing, metal filtration, metallurgy of cast alloys, alloy design, and energy and environment management. In the new edition, the author has tried to update the subject of Casting Technology and Cast Alloys within usual constraints of producing a students' textbook of convenient volume. The book is primarily designed for degree and diploma students pursuing courses in Metallurgical, Mechanical, and Production Engineering disciplines as well as for candidates studying for Associate Membership Examination (AMIIM, AMIE, and GRAD IIF). It would also benefit M.Tech/M.E. students specializing in foundry technology and allied disciplines. New to the Edition • Coverage of most recent research and industrial trial reports on metal melting, solidification, composite materials, etc. • Elaborate discussion of newer technologies in casting including Indian experience of trials with Cokeless Cupola, Composite Materials, 3-D Printing, etc. • Most recent developments in binder systems, casting practices, solidification processing, metal filtration, metallurgy of cast alloys, alloy design, and energy and environment management. Target Audience • Diploma/B.E./B.Tech. (Metallurgical, Mechanical, Production and Manufacturing Engineering) • M.Tech/M.E. (Foundry Technology and Allied Disciplines) • Professional Foundrymen and Engineers
