Aluminium Furnace Refractories must overcome the aggressive nature of molten aluminium, which deeply penetrates traditional refractories and forms destructive corundum growths.
Our specialized castables and bricks for aluminium melting and holding furnaces incorporate specific non-wetting agents (such as Barium Sulfate). These additives dramatically increase the contact angle of the molten metal, effectively preventing penetration. This eliminates corundum build-up on the walls, maintaining the furnace capacity and significantly easing cleaning and maintenance.
