Permeability of Refractory Castables at High Temperatures

Journal of the American Ceramic Society, 2001
Temperature is an important factor affectng the permeation of fluids in refractory castables. Because of experimental difficulties, however, permeability parameters are usually obtained at room temperature and then extrapolated to the temperature of interest, with no concern regarding porous structure modification (thermal expansion, etc.).

Vacuum-Cast Refractory Castables

Journal of the Structural Division, 1964
The compressive and modulus of rupture strength data for 2,400 F. to 3,400 F. commercial brands of castables and for 1 to 4 and 1 to 6 refractory concretes were investigated. The refractory concrete test specimens were prepared from the same batch of lumnite-lelite and lumnite-calcined flint clay materials.

Nanotechnology in Refractory Castables — An Overview

Interceram - International Ceramic Review, 2018
In recent times, nanotechnology has gained significant attention in the field of refractory research. As the unshaped refractory, especially the castable, is becoming of prime importance in refractory research, a good amount of work is going on globally to study the effect of nanotechnology on castables.

Refractory Castables: Preparation and Some Properties

Journal of the American Ceramic Society, 1950
Refractory castables in this investigation contained (a) aggregate made from unused high‐duty fire‐clay brick or calcined Kentucky flint clay and ( b ) domestic or imported high‐alumina hydraulic cement. The bulk densities were determined for different mixtures of grog passing through (

Very High Solids Castable Refractories

1994
Refractory shapes are conventionally produced from powder-water blends using a large variety of refractory ceramic compositions at many levels of solids loadings. Pure fine grained A12O3 may be slip cast at nearly 60 volume % solids; plastic fireclay may be cast at nearly 50 volume % solids; and some vibratory cast mixes may contain as much as 95 ...

Phase composition of bauxite-based refractory castables

Ceramics International, 2011
Abstract The bauxite-based refractory castables are composed of 90 wt.% well-graded (coarse, medium, and fine) bauxite aggregate, 10 wt.% binding matrix and adequate amount of distilled water. The binder mixture was calcium aluminate cement (CAC) containing 80% alumina and magnesium-aluminate spinel (MA-spinel) or mullite either preformed or obtained

Effect of Hydrothermal Environments on the Erosion of Castable Refractories

Journal of Engineering Materials and Technology, 1977
Hydrothermal environments are expected to adversely affect the erosive resistance of castable refractories intended for use in high wear areas of coal gasification plants. The erosive wear behavior of two grades of refractories proposed for such use was studied at room temperature after exposure of the refractories to high-pressure steam.

Damage evaluation of two alumina refractory castables

Journal of the European Ceramic Society, 2009
Abstract The accumulation of damage by thermal treatment and its development under uniaxial loading–unloading cycles performed at room temperature has been evaluated for two alumina based refractory castables; an ultra low cement content bauxite material (Bau-ULCC) and a low cement content andalusite material (And-LCC).

Selection of binders for in situ spinel refractory castables

Journal of the European Ceramic Society, 2009
Abstract The expansive behavior of alumina–magnesia refractory castables is usually associated with in situ spinel formation. Nevertheless, when bonded with calcium aluminate cement (CAC), this class of materials can present additional expansion reactions due to CA 2 and CA 6 formation.

Effect of Al4SiC4 on the Al2O3SiCSiO2C refractory castables performance

Ceramics International, 2012
Abstract Carbon-containing refractories are widely used in the steelmaking process due to their outstanding properties and, in order to improve their oxidation resistance, the so-called antioxidants have often been used. Al 4 SiC 4 is pointed out as a novel additive that presents suitable properties such as Al, but without its drawbacks.
