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.
2.Resistant to highest temperature for steelmaking operations such as ladle applications, sidewall, roofs, burner blocks, anchor brick for reheating furnaces and many other areas.
3.transition and cooling zones of rotary cement kilns, lime kilns , etc.
4.lower sidewall and bottom of aluminum refining,melting furnaces ,etc.

- Q:Can insulating fire bricks be used in the construction of boilers for power plants?
- Yes, insulating fire bricks can be used in the construction of boilers for power plants. These bricks have excellent insulating properties, which help to retain heat and increase energy efficiency in the boilers. Additionally, their lightweight nature reduces the overall weight of the construction, making them a suitable choice for power plant boilers.
- Q:What is the typical compressive strength of an insulating fire brick?
- The typical compressive strength of an insulating fire brick ranges from 1,000 to 3,000 pounds per square inch (psi).
- Q:Can insulating fire bricks be custom-made?
- Yes, insulating fire bricks can be custom-made. Insulating fire bricks are typically made from lightweight materials such as vermiculite, perlite, or refractory fibers, which can be easily molded into various shapes and sizes. This flexibility allows manufacturers to create custom-made insulating fire bricks to meet specific requirements and applications. Customization options may include variations in dimensions, thermal conductivity, compressive strength, and density. By tailoring the composition and design of insulating fire bricks, they can be optimized for specific temperature ranges, insulation requirements, and environmental conditions. Therefore, customers can work with manufacturers to develop custom solutions that best suit their unique needs.
- Q:Are insulating fire bricks resistant to erosion from flowing gases or liquids?
- Generally, insulating fire bricks exhibit resistance to erosion caused by flowing gases or liquids. These bricks are designed to possess excellent thermal insulation properties and the ability to withstand high temperatures, making them suitable for a wide range of industrial uses. The bricks are constructed from lightweight refractory materials with low porosity, which aids in minimizing the infiltration of gases and liquids. Moreover, insulating fire bricks often exhibit chemical inertness, further enhancing their erosion resistance. However, it is crucial to acknowledge that the erosion resistance of these bricks may vary depending on factors such as composition, manufacturing process, and the characteristics of the flowing gases or liquids. Therefore, it is advisable to consult the manufacturer or a qualified expert to assess the suitability of insulating fire bricks for a specific application.
- Q:Can insulating fire bricks be used in the construction of radiant tubes?
- Yes, insulating fire bricks can be used in the construction of radiant tubes. These bricks are designed to have low thermal conductivity, which makes them an excellent choice for insulating applications such as radiant tubes. They can help to minimize heat loss and improve the efficiency of the radiant heating system.
- Q:How shall the sintered porous self insulation bricks be laid at the bottom of the beam?
- And the concrete beam should be broken brick masonry. Top packing.
- Q:Are insulating fire bricks resistant to fire?
- Yes, insulating fire bricks are specifically designed to be highly resistant to fire. They have excellent insulating properties and can withstand high temperatures without cracking or breaking down.
