We offer an extensive portfolio of high-performance refractory products, carefully developed to sustain extremely high temperatures, increase efficiency, and extend the lifespan of your industrial assets.
Let us now explore some of our main products, explaining their specifications, features, and uses to enable you to make the right choices for your projects.
1. High Alumina Fire Bricks: The Apex of Thermal Endurance
Where normal fire bricks cannot handle intense heat, High Alumina Fire Bricks take the stage. These refractory bricks are specifically designed with a greater proportion of alumina (Al2O3) that provides them with enhanced strength and heat resistance.
Specifications:
- Alumina Content: Generally between 45% and more than 85%, varying with the grade.
- Refractoriness Under Load (RUL): Excellent, usually beyond 1500°C for higher alumina grades.
- Cold Crushing Strength (CCS): High for strong mechanical strength even at high temperatures.
- Porosity: Controlled to provide maximum insulation and resistance to slag penetration.
- Standard Sizes: Supplied in standard sizes (e.g., 230mm×114mm×75mm) and made to order shapes.
Key Features:
- Exceptional High-Temperature Resistance: Suitable for conditions up to well in excess of 1600°C.
- Superior Abrasion and Corrosion Resistance: Resists severe chemical attack and wear by molten materials.
- Excellent Thermal Shock Resistance: Resists sudden heating and cooling without spalling.
- High Density and Low Permeability: Reduces gas and liquid infiltration, prolonging life.
Applications:
- Steel Industry: In blast furnaces, hot blast stoves, steel ladles, and electric arc furnaces cover.
- Glass Industry: Lining glass melting tanks and regenerators.
- Cement & Lime Kilns: Essential for the burning and preheating zones.
- Petrochemical Industry: For reactors and high-temperature process units.
- Incinerators: Offering durable lining in waste incinerators.
2. Boiler Fire Bricks: Protecting Your Powerhouse
Boilers are the lifeblood of most industrial processes, and their lifespan is a function of the quality of their refractory lining. Our Boiler Fire Bricks are specially designed to resist the severe heat, corrosive fumes, and thermal cycling that characterize boiler surroundings.
Specifications:
- Refractoriness (PCE): High, typically above 1600°C.
- Thermal Conductivity: Moderate to low, providing effective insulation.
- Chemical Resistance: Good resistance to alkalis, sulfates, and other corrosive elements found in combustion gases.
- Density: Optimized for strength without excessive weight.
- Standard Sizes: Various sizes available to suit different boiler designs.
Key Features:
- Consistent Heat Containment: Provides effective energy use and minimizes heat loss.
- Flue Gas Attack Resistance: Resists corrosive atmospheres, inhibiting premature wear.
- Mechanical Stability: Provides structural integrity under normal operating conditions.
- Installation Convenience: Standardized form allows for rapid, efficient lining.
Applications:
- Industrial Boilers: Lining of combustion chambers, flues, and ash pits.
- Waste Heat Recovery Boilers: Guarding exposed regions of high-temperature exhaust gas.
- Power Generation Plants: Essential for coal-fired, gas-fired, and biomass boilers.
- Incinerators & Furnaces: Where hardy and heat-resistant linings are needed.
3. Ceramic Fiber Blanket: Lightweight Insulation, Heavyweight Performance
For use in high-performance, lightweight, and flexible insulation applications, Ceramic Fiber Blanket is the unequalled option. Comprising high-purity alumina-silica fibers, these blankets provide excellent thermal insulation characteristics. Apart from that, we also provide related products such as Ceramic Fiber Board, Ceramic Fiber Paper Insulation sheet/roll, and we provide competitive ceramic fiber blanket prices to suit all your requirements.
Specifications:
- Classification Temperature: Varies from 1260°C to 1600°C, as a function of fiber type (e.g., RCF, AES, Polycrystalline).
- Density: Provided in different densities (e.g., 64, 96, 128 kg/m3) for specific application requirements.
- Thickness: Typical thicknesses are 12.5mm, 25mm, and 50mm.
- Thermal Conductivity: Very low, with excellent insulation.
- Chemical Composition: Alumina-Silica fibers of high purity.
Key Features:
- High Thermal Insulation: Substantially decreases heat loss and energy usage.
- Lightweight and Flexible: Simple to handle, cut, and install around intricate shapes.
- High Thermal Shock Resistance: Immune to abrupt temperature changes.
- Low Heat Storage: Warms up and cools rapidly, enhancing furnace cycle times.
- Chemical Stability: Immune to most chemical attacks (except hydrofluoric and phosphoric acids).
Applications:
- Furnace and Kiln Linings: As the main hot face lining or secondary insulation.
- Boiler Duct and Stack Linings: Serving as important insulation for exhaust systems at high temperatures.
- Process Heaters: Insulating industrial heating equipment.
- Expansion Joint Sealing: Accommodating thermal expansion in refractory installations.
- Fire Protection: Applied in passive fire protection systems owing to its non-flammability.
4. Refractory Fire Cement: The Bonding Agent for Endurance
No refractory installation is complete without a superior quality bonding agent. Refractory Fire Cement, otherwise referred to as refractory mortar, is essential for binding fire bricks, producing a monolithic and strong lining that can sustain the most adverse conditions.
Specifications:
- Service Temperature: Equal to or greater than the heat resistance of the bricks being bonded, usually up to 1600°C.
- Setting Type: Air-setting or Heat-setting.
- Chemical Composition: Alumina-silicate based, usually containing additives for workability and strength.
- Consistency: Dry powder (mix with water) or ready-mix paste.
- Bonding Strength: Strong, long-lasting bond between refractory elements.
Key Features:
- High-Temperature Stability: Resists structural distortion and bonding weakening at high temperatures.
- Good Adhesion: Produces a strong, uniform bond with many types of refractory bricks and shapes.
- Thermal Expansion Compatibility: Expands and contracts with the bricks to avoid cracking and spalling.
- Gas Tightness: Forms an unbroken joint, avoiding heat leak and entry of corrosive gases.
- Easy to Use: Convenient consistency for effective bricklaying and patching.
Applications:
- Laying Refractory Bricks: Critical for building furnace linings, kilns, and boilers.
- Repair and Patching: Utilized for the repair of cracks, spalls, and deteriorated refractory linings.
- Bonding Ceramic Fiber Products: May be utilized for bonding fiber modules or blankets in certain applications.
- Protective Coatings: Used as a thin wash coat to improve the surface protection of refractory products.
