Refractory fire bricks

Refractory Firebricks for High-Temperature Industrial Processes - up to 1650°C / 3000°F

Vitcas Refractory Fire Bricks are dense, clay-based refractory components formulated for high mechanical strength, thermal stability, and resistance to chemical corrosion. Manufactured using precisely graded fireclay with controlled alumina content, these bricks are suitable for static and dynamic high-temperature applications in aggressive industrial environments.

Technical Specifications

• Maximum Service Temperature: 1650°C / 3000°F

• Material Composition: Fireclay with 42% or 60% Al₂O₃ (alumina content)

• Density: High-density format for increased thermal mass and durability

• Thermal Shock Resistance: Excellent, suitable for repeated heating and cooling cycles

• Chemical Resistance: Available in acid-resistant formulations for corrosive conditions

Product Variants

• Standard Refractory Fire Bricks (42% or 60% alumina) - Designed for use in high-load, high-temperature settings including kilns, forges, and incinerators.

• Arch Bricks - Precision-shaped bricks for constructing arched roofs in thermal chambers, including tunnel kilns and vault-style furnaces.

• Acid-Resistant Fire Bricks - Manufactured with enhanced silica content and specialised additives to resist acid attack and abrasion-ideal for chemically aggressive installations.

Industrial Applications

• Metallurgical Industry - Refractory linings for blast furnaces, ladles, tundishes, and reheat furnaces used in ferrous and non-ferrous metal production.

• Ceramics and Glass Manufacturing - High-temperature insulation for kilns, furnace superstructures, and glass melting or holding tanks requiring dimensional stability and thermal shock resistance.

• Power Generation - Thermal linings for biomass and coal-fired boilers, gasification units, and slag-resistant zones in high-wear combustion areas.

• Cement and Lime Industry - Refractory solutions for rotary kilns, preheater towers, calciners, and flue ducting exposed to high thermal loads and chemical attack.

• Chemical and Petrochemical Industry - Acid-resistant firebrick linings for acid recovery plants, sulphur furnaces, and chemical reactors operating under corrosive and abrasive conditions.

• Aluminium Industry - Firebrick linings for holding furnaces, melting furnaces, and transfer launders, resistant to molten aluminium corrosion and mechanical erosion.

• Incineration and Waste Treatment - Heat- and slag-resistant bricks used in combustion chambers, ash hoppers, and waste-to-energy units subjected to cyclic thermal loads and aggressive residues.
