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 ...

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

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 ...

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
