VITCAS Fire bricks 230x114x76mm

Fire Bricks 42% Alumina - High Duty Refractory Bricks for Extreme Heat Applications

VITCAS 42% Alumina Fire Bricks are engineered for excellence, classified as High Duty bricks. These fire bricks are capable of withstanding extreme temperatures, with a maximum service temperature of up to 1430°C /2600°F. Each fire brick measures 230 x 114 x 76mm (9" x 4½" x 3") and weighs approximately 4.5 kilograms, meticulously designed for high-performance applications.

Key Features

• Alumina Content: Contains a minimum of 42% Al₂O₃ (aluminium oxide), ensuring excellent refractoriness and heat resistance

• Low Iron Content: Reduces oxidation risks and enhances thermal stability in reducing atmospheres

• Low Alkali Content: Reduces the risk of alkali-related degradation, improving chemical durability and brick lifespan

• Thermal Shock Resistance: Withstands rapid heating and cooling cycles without cracking-ideal for high-temperature, high-stress environments

• Abrasion Resistance: Built to endure mechanical wear from fuels, tools, or product movement

• High Density and Strength: Dense composition provides excellent load-bearing strength and thermal efficiency

Applications

• Kiln Linings: Perfect for use in high-temperature kilns in ceramics and metal casting industries.
• Ceramics: Ideal for the construction and maintenance of ceramic furnaces.
• Metal Casting: Provides reliable and efficient lining for metal casting furnaces.
• Incinerators and Cremators: Exceptionally suited for high-temperature incinerators and crematoriums.

Installation Recommendation

For the best results, we recommend using Vitset 45 - Refractory Mortar 1700°C for setting Vitcas 42% alumina fire bricks, ensuring a strong and durable bond.

Manufacturing Tolerance and Variations:

Please note that due to the inherent manufacturing process, there may be slight variations of +/-3mm in the size of the bricks. Similarly, subtle colour variations may occur between bricks, which does not affect the product's performance. It is also normal to find small chips on the bricks; this is not a product fault but rather a characteristic of the fire clay brick. These can be easily covered by Refractory Mortar or Cement, if required.
