Fundamental Design of Steelmaking Refractories Comprehensive up-to-date resource organizing fundamental aspects for the design and performance of steelmaking refractories Fundamental Design of Steelmaking Refractories provides a fundamental understanding in the design of steelmaking refractories, in detail and all in one source, enabling readers to understand various issues including how heat and mass transfer occurs throughout the refractory, how matrix impurity or their contact affects the phases, and how invisible defects form during refractory manufacturing that eventually facilitates to analyze wear, corrosion, and performance of different refractory linings for primary and secondary steelmaking vessels, tundish, and continuous casting refractories. Other specific sample topics covered in Fundamental Design of Steelmaking Refractories include: Phase formations and correlation with impurity effects and refractory processing shortcomingsStress, wear, and corrosion to design refractories and performance statistics of steelmaking refractoriesEquilibrium and non-equilibrium phases, packing, stress and defects in compaction, and degree of ceramic bondingThermal and mechanical behavior, flow control mechanisms, continuous casting refractories, and premature refractory damagePrecast and purging system, consistent supply and time management, and preventive maintenance in operation With its complete coverage of the subject, Fundamental Design of Steelmaking Refractories fulfills the academic demand of undergraduate, postgraduate, and research scholars of ceramic engineering; metallurgical engineers and mechanical engineering outlets that want to nurture in the refractory and steel sectors will also find value in the text.

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, andas 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 discusses fundamentals of nanostructured ceramics involving functional, structural and high temperature materials. It provides both solved numerical problems and unsolved problems to enable the reader to envisage the correlation between synthesis process and properties in the perspective of new material development. It serves as a concise text to answer the basics and achieve research goals for academia and industry. Key Features Deals with basic strategy on data interpretation for nanostructured ceramics Proposes to bridge the gap between the nano and bulk properties of nanostructured ceramics Discusses brief schematics and equations to understand the different properties of nano to bulk ceramics Presents mode of data acquisition and interpretation through statistical module and solved numerical Includes unsolved numericals based on properties, data acquisition and interpretation

In this book, A theoretical model of energy loss mechanism as a function of electron temperature and electron concentration has been given for n-type GaN structures. The energy relaxation rates and mobility for warm and hot electrons have been calculated for over the electron temperature(T) range of 1.5 to 500 K at lattice temperature T0=1.5 K. It has been found that the acoustic phonon scattering due to deformation potential and piezoelectric coupling are the dominant scattering mechanisms at low electron temperatures (Te100 K, the polar optic phonon scattering becomes the effective scattering mechanism. The optic phonon energy of GaN was obtained as 91.8 meV and the PO phonon emission time as 8.6 fs. Also, the drift velocity of electrons as function of electron temperature and electric field has been obtained. The theoretical results are compared with available experimental results and a good agreement is observed.
