Insulating Fire Bricks

Lanexis offers high-quality insulating firebricks, classified according to the ASTM standards. These firebricks are manufactured from high-purity refractory clays, graduated alumina, and carefully graded organic fillers that burn out during production, creating a uniform and controlled pore structure. Our insulating firebricks are shaped through casting, extrusion, or foaming methods, high-temperature sintered in natural gas-fueled tunnel kilns.

Hot Face Kyanite (HFK) insulation bricks are widely used, cost effective bricks which are primarily used as the working face in furnaces, kilns, and other high-temperature processing equipment. 

Features: 

  • High Temperature Resistance:
  • Withstand temperatures up to 1,260°C (2,300°F)
  • Low Thermal Conductivity: Improving energy efficiency in high-temperature applications.
  • Kyanite provides High Strength and Durability
  • HFK bricks are resistant to thermal shock, mechanical wear, and chemical attack.
  • Lightweight Despite their strength

Our Range: 

  • HFK 140
  • HFK 150
We also offer high performance diatomite & molar insulation bricks on request. These bricks are used for specialized applications with high strength and low density.
• High strength,
• Low heat capacity
• Low thermal expansion
Their thermal shock resistance is high due to low thermal expansion and contraction factors. They have low permeability against gases and resistance to weak acids. These insulation bricks are used as back-up insulation in the industrial furnaces.

Features

Know More About
The Product

Low Reheat Change:

Low PLC results assured safety in application and long life span.

Low Thermal Conductivity:

Good thermal insulation makes thinner furnace walls possible, improving efficiency & lower operation cost, making a contribution to environmental protection.

Low Density & Low Heat Storage:

Due to lightweight and low thermal conductivity, bricks absorb less heat inward, which means reduced fuel cost and fast heating up in cyclical operation heating equipment.

High Purity:

Low in impurity like Iron & alkali flux content to realize refractory performance in specified atmosphere.
