Corrosion resistance of refractory castables in dynamic conditions
NOVYE OGNEUPORY (NEW REFRACTORIES), 2022Tests of corrosion resistance of refractory castables to borosilicate glass melt under dynamic conditions were carried out. A method for calculating various indicators characterizing the glass resistance of a refractory exposed to glass melt is presented. On the basis of the data obtained during the tests, the rates of linear corrosion of the submerged

Calcium Aluminate Cement and Refractory Castable
Transactions of the Indian Ceramic Society, 1993Monocalcium 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, 2001Temperature 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, 1964The 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.

Refractory Castables: Preparation and Some Properties
Journal of the American Ceramic Society, 1950Refractory 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
1994Refractory 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 ...
