Binders for Refractory Castables: An Overview

Interceram - International Ceramic Review, 2020
Abstract: A binder for refractory castables is a bonding material that bonds a loose powdery mix, retains its shape after casting and allows the cast shape to set and harden for handling and further processing. A binder also improves sintering, as the castables are not compacted during shaping, causing poor densification and strength.

The Use of Refractory Castables in the Ferrous Metallurgy

Refractories and Industrial Ceramics, 2003
Products commercially available from the Ogneupornye Tekhnologii Joint-Stock Co. are described and their physicochemical characteristics presented. Results for refractory castables tested under industrial conditions are presented and compared with those of foreign analogs.

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 (

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.

Calcium Aluminate Cement and Refractory Castable

Transactions of the Indian Ceramic Society, 1993
Monocalcium aluminate and calcium dialuminate were prepared by heating different mixes of CaO and Al2O3, at 1400° and 1600°C respectively, evidence of which was found by X-ray diffraction study. Castables were made from the mixes of CA and CA2 in specific proportions, hydrated by keeping immersed in water and subsequently tested for strength.Hydrated ...

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.).

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 ...

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.
