Castable refractory concretes

International Materials Reviews, 2001
Castable refractories containing calcium aluminate cement (CAC) are used ubiquitously in a range of furnace lining applications in the iron and steel, cement, glass, ceramic, and petrochemical industries. This review outlines their development from conventional high cement materials, through low cement and ultra-low cement castables to the present ...

Nano-bonded refractory castables

Ceramics International, 2013
Abstract Calcium aluminate cement (CAC) contents higher than 3 wt% in refractory castables can have some drawbacks in the various processing steps (mainly drying) and also in their refractoriness when in contact with SiO 2 . The use of colloidal silica as an alternative binder has been studied by many researchers in recent years and recently reports ...

Silicon carbide refractory castables

Refractories and Industrial Ceramics, 2005
Optimum formulations for castables intended for different service conditions are proposed. Silicon carbide castables containing ultradisperse particles of cement, silica fume, and electrofused corundum are developed. The castables do not weaken on heating and display superior operational properties: the compressive strength is 40–80 MPa at sintering ...

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.

Thermal Conductivity of Refractory Castables

Journal of the American Ceramic Society, 1963
Thermal conductivity measurements were made on various refractory castabales of both dense fireclay and high‐alumina types as well as on several insulating castables. These tests, covering mean specimen temperatures of 200° to 2000°F, indicated how the thermal conductivity of a castable material varies with thermal history.

Corrosion resistance of refractory castables in dynamic conditions

NOVYE OGNEUPORY (NEW REFRACTORIES), 2022
Tests 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
