High Alumina Refractory Fire Bricks For Ceramic Tunnel Kiln , Iron Making Furnaces Firebrick
High alumina insulation brick is a specialized refractory material designed for superior thermal insulation in high-temperature industrial applications. Made from high-purity alumina, these bricks provide excellent heat resistance, low thermal conductivity, and reliable mechanical strength. Widely used alongside alumina refractory bricks, the lightweight alumina bubble brick variant offers enhanced energy efficiency and reduced furnace load.Designed for high thermal efficiency and durability, the high alumina insulation brick, along with alumina refractory bricks and alumina bubble brick, ensures reliable performance and energy savings in demanding high-temperature applications.
Key Features
Low Thermal Conductivity – High alumina insulation brick minimizes heat loss and improves energy efficiency in furnaces.
High Temperature Resistance – Suitable for continuous use at temperatures up to 1750°C.
Lightweight & Durable – Alumina bubble brick provides reduced bulk density while maintaining structural integrity.
Chemical and Thermal Stability – Resists acidic and neutral slags, ensuring long-term performance.
Versatile Applications – Can be used in combination with standard alumina refractory bricks for optimal insulation and protection.
Description:
Laurel high alumina bricks are produced with selected bauxite chamotte by advanced process and strict quality control. The main mineral components are corundum and mullite phases. It features excellent high temperature mechanics and chemical corrosion resistance.
The most competitive price,good quality,safty packing,prompt delivery time,and excellent after-sales services.
Lower ferric Oxide,lower porosity,higher refractoriness,higher density,higher CCS and exact tolerance.
