This comprehensive reference details the technical, chemical, and mechanical aspects of high-temperature refractory composite materials for step-by-step guidance on the selection of the most appropriate system for specific manufacturing processes. The book surveys a wide range of lining system geometries and material combinations and covers a broad/5(3).
Creep at high temperature: Creep is a time dependent property, which determines the deformation in a given time and at a given temperature by a refractory material under stress.
Volume stability, expansion, and shrinkage at high temperatures: The contraction or expansion of the refractories can take place during service Size: 1MB. The final objective of this project was to design and build a bench-scale high-temperature controlled atmosphere dynamic corrosion application furnace (CADCAF).
The furnace will be used to evaluate refractory test samples in the presence of flowing corrodents for extended periods, to temperatures of C under controlled atmospheres. Blond; 7-Impact of operating conditions on refractory lining wear by J.
Poirier and M. Rigaud. The content of the book has been reviewed by fourteen fellow experts (industrials and academics) worldwide. It represents a major contribution to grasp in depth the main principles to address the major issues concerning the corrosion of refractories.
Refractory materials that keep their chemical and physical strength at temperatures above °C are of high importance for metallurgical and other industrial processes. They consist of alumina, magnesia, silica, lime, and other metal oxides. Global production for the metal, glass, and ceramics industries is about 12 million metric tons.
However, high-temperature properties such as static corrosion at °C and hot modulus of rupture at °C indicated that there is an upper constraint to the amount of substitution. gasification at high temperature ( ⁰C) good sulphur resistance. Phosphate modified high-chrome oxide refractory material Fused and fused cast magnesia and magnesia-spinel bricks have shown good slag resistance in gasification at moderate.
The U.S. Department of Energy's Office of Scientific and Technical Information. This book examines the latest developments in the understanding of high temperature corrosion processes and protective oxide scales and coatings.
Part one looks at high temperature corrosion. Chapters cover diffusion and solid state reactions, external and internal oxidation of alloys, metal dusting corrosion, tribological degradation, hot. In practical terms, refractories are products used for high temperature insulation and erosion/corrosion and are made mainly from non-metallic minerals.
They are so processed that they become resistant to the corrosive and erosive action of hot gases, liquids and solids at high temperatures, in various types of kilns and furnaces. The book will be a useful addition to any library on refractories, to be read in conjunction with others in the field.

The erosion‐corrosion resistance of the plasma‐sprayed nanostructured titanium dioxide coatings depends largely upon the characteristics of feed powder and its reconstitution. Dense, uniform, and evenly dispersed nanostructured constituents provide a high coating integrity, which offers high resistance to erosion‐corrosion.

Zirconia refractories – In zirconia refractories, main constituent of the refractory is zirconium oxide (ZrO2). Zirconia refractories are useful as high temperature construction materials. They tend to be used in applications where temperatures are above deg C such as casting nozzles and gates, crucibles, furnace liners and kilns.
The erosion resistance of dense refractory bricks or castables used in CFBC boilers is tested as per ASTM C This method of testing determines the relative erosion of a refractory at room temperature only.
Hence, solid particle erosion at elevated temperatures is desired in selecting the suitable refractory quality for boiler applications. The major reason why the abrasion resistance of refractories is hard to predict at their working temperature is due to two main factors: 1.
Lack of adequate tools able to test the abrasion at high temperature; 2. Abrasion wear of refractories is affected by other mechanisms such as erosion, corrosion, mechanical impact and/or thermal shock.

Thompson, R. John, and A. Young. The attack of molten glass on refractory materials is of prime importance to both the glassmaker and refractory manufacturer. Over a period of several years we have developed what are now regarded as the standard tests for the assessment of refractory corrosion.
Two basic tests have been developed for the investigation of refractory attack, as follows: Corrosion Test This involves the. Refractories are heat resistant materials used in almost all processes involving high temperatures and/or corrosive environment.
These are typically used to insulate and protect industrial furnaces and vessels due to their excellent resistance to heat, chemical attack and expansion and shrinkage at high temperature.Refractories are considered the critical factor for successful and reliable operation of many high-temperature industrial processes.
They are often a major cost item both in general maintenance and also in terms of unscheduled downtime of production units arising from premature material failure.• AGC produces products with higher strength, thermal shock resistance, erosion/corrosion resistance when compared with equivalent conventional castables.
The Benefits: • Higher performance vs equivalent conventionally cast pieces • Commercial savings vs conventional cast for same performance.
