Fundamental Design of Steelmaking Refractories

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 shortcomings
* Stress, wear, and corrosion to design refractories and performance statistics of steelmaking refractories
* Equilibrium and non-equilibrium phases, packing, stress and defects in compaction, and degree of ceramic bonding
* Thermal and mechanical behavior, flow control mechanisms, continuous casting refractories, and premature refractory damage
* Precast 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.
