This book enables the reader to gain a fundamental understanding in the design of steelmaking refractories details all in one source. Readers will be able 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 topics include the thermal and mechanical behavior, flow control mechanisms, continuous casting refractories, and premature refractory damage.
