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.

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).

Lightweight corundum–spinel ladle wear lining castable with low thermal conductivity

Journal of The American Ceramic Society
Designing a lightweight wear‐lining refractory is of great significance for energy savings and consumption reduction. In this study, an in‐house manufactured porous alumina aggregate was selected to replace the commercial tabular alumina aggregate to ...

Use of alumina dispersant in alumina‐spinel castable: Comparison between in situ and preformed spinels

International Journal of Applied Ceramic Technology
The role of alumina dispersant as a flow modifier, completely replacing fume silica, on the properties of preformed and in situ spinel‐containing low cement high alumina castables was investigated with variations in spinel content and granulometry.

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.

Transient Properties of Refractory Castable with Hydraulic Binders

2014
Refractory castables based on hydraulic binders have a widespread use in aluminium casthouses (furnaces, launders, etc.). Their selection is based on properties such as corrosion resistance to molten metal, mechanical behavior and insulation. Few studies concern the hydric exchanges between the refractory materials and the surrounding atmosphere, while
