refractory lightweight high alumina thermal insulating fire brick
Product Description
Refractory lightweight high alumina thermal insulating fire brick is made out of a naturally-occurring material known as bauxite. This material includes aluminum hydroxide, which is what gives the bricks such great warmth resistance. The bricks also include kaolinitic clays, which are roasted to create an unique combination including mullite and also synthetic alumina. This is where the name “high alumina” stems from.
Features
1.High-temperature endurable .
2.Good thermal shock resistance .
3.High cold crushing strength.
4.Good resistance to abrasion and corrosion.
5.Good thermal spalling resistance.
6.High mechanical strength.
7.Good volume stability at high temperature.
Application
1.General use in heat containment unit form temperature 1500-2000°C.

- Q: Do insulating fire bricks have a high fireproof rating?
- Indeed, insulating fire bricks possess a remarkable fireproof rating. These bricks have been specifically engineered to endure exceedingly high temperatures and offer exceptional insulation against the transfer of heat. They are crafted using specialized refractory materials with limited thermal conductivity, thereby aiding in the retention of heat and preventing its escape from the system. Insulating fire bricks are capable of withstanding temperatures ranging from 2300°F to 3100°F (1260°C to 1700°C), rendering them ideal for utilization in furnaces, kilns, fireplaces, and other applications involving elevated temperatures. Their elevated fireproof rating guarantees their ability to effectively safeguard structures and equipment from the intense heat and flames, enabling secure and efficient operations across diverse industries.
- Q: Can insulating fire bricks be used in the construction of pottery kiln shelves?
- Indeed, pottery kiln shelves can be constructed using insulating fire bricks. These bricks are specifically engineered to endure extreme temperatures while offering exceptional insulation, rendering them an optimal choice for kiln shelves. Their utilization aids in maintaining a uniform dispersion of heat and averting thermal shock, a critical aspect in the pottery firing process. Moreover, the lightweight and manageable nature of insulating fire bricks make them a pragmatic option for the construction of kiln shelves.
- Q: Can insulating fire bricks be used for insulation in cold storage facilities?
- Yes, insulating fire bricks can be used for insulation in cold storage facilities. These bricks have excellent thermal properties and can effectively prevent heat transfer, making them suitable for maintaining low temperatures in cold storage facilities.

- Yes, insulating fire bricks are generally resistant to acids. They are made from materials that can withstand high temperatures and are chemically stable, making them suitable for applications where acid resistance is required.
- Q: Can insulating fire bricks be used for insulation in ovens and kilns?
- Insulating fire bricks are indeed suitable for insulation in ovens and kilns. These bricks are specially designed to withstand high temperatures and offer exceptional thermal insulation. They are composed of lightweight materials such as clay and other refractory substances with low thermal conductivity. Consequently, they possess the ability to effectively retain heat and prevent its escape, making them an ideal choice for ovens and kilns where heat retention is of utmost importance. Furthermore, insulating fire bricks possess resistance against thermal shock, enabling them to endure rapid temperature changes without cracking or breaking. Ultimately, insulating fire bricks guarantee efficient heat distribution and energy conservation, making them a reliable option for insulating ovens and kilns.
- Q: Are insulating fire bricks suitable for use in boilers?
- Boilers can indeed utilize insulating fire bricks. With their ability to withstand high temperatures, insulating fire bricks prove themselves as a viable option for a range of applications, including boilers. These bricks are crafted from lightweight materials like ceramic fibers or vermiculite, imparting exceptional thermal insulation properties. Consequently, they proficiently trap heat within the boiler, curbing heat loss and enhancing energy efficiency. Furthermore, insulating fire bricks exhibit resilience against thermal shock, chemical attack, and corrosion, ensuring their endurance and longevity in boiler settings. In summary, incorporating insulating fire bricks in boilers can optimize performance, decrease energy consumption, and elevate the overall efficiency of the heating system.
- Q: Can insulating fire bricks be used in contact with molten metals?
- Yes, insulating fire bricks can be used in contact with molten metals. Insulating fire bricks are designed to withstand high temperatures and provide excellent insulation properties. They are commonly used in applications where there is a need to contain and distribute heat, such as in kilns, furnaces, and industrial ovens. When in contact with molten metals, insulating fire bricks can withstand the extreme heat and prevent heat transfer from the molten metal to the surrounding environment. This helps to maintain temperature stability and protect the structural integrity of the equipment. However, it is important to note that the specific type and composition of insulating fire bricks should be carefully chosen based on the temperature and the type of molten metal they will come into contact with. Different metals have different melting points and can have varying corrosive effects on different materials. Therefore, consulting with experts or manufacturers is recommended to ensure the right type of insulating fire bricks are selected for each specific application.
- Q: Do insulating fire bricks provide sound insulation as well?
- No, insulating fire bricks are primarily designed to provide thermal insulation and are not specifically designed for sound insulation.
- Q: Clay insulation bricks insulation, brick and ordinary clay brick, fireclay, brick distinction, and its use? Thank you
- The insulation brick integrates the excellent heat preservation effect into the wall while building the wall. Low thermal conductivity, high strength, durable, lightweight, simple construction, easy handling, economy, green environmental protection, sound insulation, fire protection etc..
