Castables

Various qualities of silicon carbide based castable, gunning, ramming & plastic. Typical 60%-80% SiC content, specialist materials with lower or higher SiC content also available.

Refrax® Procast, Progun, Proram & Proplast are designed to compliment our tile and brick systems to give full lining capability.

They can be used together with the tiles or equally effective on their own.

Advantages:

Excellent oxidation resistance
Good strength and stability
Good abrasion resistance

Mortar

Mortars

Either traditional for trowel application or self-leveling for back-cast systems, the Refrax® range has a product for you.

Bonding and carefully selected raw materials ensure high adhesion, great strength and resistance to conditions inside the boiler. Their excellent adhesion and stability offer a secondary defense to corrosion behind the tiles and protection to the anchor.

Refrax® PLUSflow: A self-leveling product for backfilling with maximized thermal conductivity is the best selection for our T-Clip systems.

Advantages:

Excellent resistance to corrosion from gases at low temperatures
Good fractures toughness at middle temperatures

WTE Products, Carbal Carbofrax | Saint-Gobain

Special Products

Carbal® 130 consists of 40% AL2O3 and 50% high-quality SiC .

Applications: special bricks and tiles where the conductivity of the lining needs to be controlled at a lower level. Similar level to a monolithic lining but with the speed and flexibility of installation of a tile system.

CARBOFRAX®: The traditional silicate bonded SiC. Excellent low temperature corrosion resistance due to the glazed surface which acts as a seal & protection to gas passage.

Applications: special bricks, standard tiles in T-Clip or 45° design.
