[{"$nulls":4},"Flow Control', 'Refractories for Continuous Casting', and 'Premature Refractory Life by Other Parameters', are essential to acme. These issues have been discussed in the second half of the book to fulfill the academic demand of undergraduate, postgraduate, and research scholars of ceramic engineering, metallurgical engineering, and mechanical engineering outlets who want to nurture in the refractory and steel sectors. The description of such cumulative basic knowledge, collective shop floor data, and relevant failure analysis criteria makes sense and eventually stimulates the awareness of how to grasp and analyze a particular class of refractory for steelmaking. Refractory production, as fighting fit as their consumption, includes a certain degree of heat and mass transfer. Preliminary from the thermodynamics, heat and mass transfer mechanisms are being described, and eventually, an analogy is drawn in Chapter 1. In-situ phase formation during manufacturing and transformation in the presence of impurities are common phenomena in refractory, and thus fundamentals of binary and ternary equilibrium phases and non-equilibrium phases are described in Chapter 2. Optimum compaction and load are a prerequisite to press organic-bonded refractories. A low load regime results in low green density, whether high load beyond critical stress consequences spring back and expedite lamination that eventually produces defect and early stage failure during the maneuver. Such phenomena are deliberated in Chapter 3. Industrial-scale production demands a uniform temperature distribution throughout the kiln to form adequate ceramic bonding or sintering of compact mass otherwise results in premature refractory failure. In this regard, Chapter 4 describes the initial and final stages of sintering, densification, grain growth, and their shape in the matrix. Even with refractory processing failure, meticulous thermal and mechanical stress cracking, severe wear aggravated by abrasion, and corrosion are unavoidable in refractory practice and applications. In these concerns, Chapter 5 highlights the thermal and mechanical behavior, and Chapter 6 underscores the high temperature corrosion mechanism with a relevant model\"--"]
