Bubble Alumina Brick and Insulating Firebrick are high temperature refractory brick, max temp 1800 deg C, used in furnace kiln.

Bubble Alumina Brick and Insulating Firebrick are high temperature refractory brick.

 

Bubble Alumina Brick. We stock in both 2.5 & 3” sizes. We also carry double bump interlocking anchor styles. For use up to 1800C, these brick have excellent insulating properties as well as high hot strengths.

 

Insulating firebrick, we carry produces thirteen types of Insulating Fire Brick for use in applications from 2,000°F (1,093°C) to 3,200°F (1,760°C). Each type is formulated to meet specific thermal and physical requirements and after firing is machined to precise tolerances.

 

Made from high purity refractory clays and other ceramic raw materials, these insulating fire brick contain a carefully graded organic filler which is burned out during manufacture to give a uniform controlled pore structure.

 

Strong

The high compressive strength of bubble alumina brick allows for self-supporting structures at elevated temperatures. Insulating fire brick are compatible with dense fire brick and add strength to the whole construction.

 

Low Heat Storage

Lower heat storage versus dense brick means reduced fuel costs in cyclically operated heating equipment.

Q:Can insulating fire bricks be used in drying ovens?
Yes, insulating fire bricks can be used in drying ovens. These bricks are designed to withstand high temperatures and provide insulation, making them suitable for use in ovens where drying processes occur. They help to maintain a consistent and efficient heat distribution, ensuring effective drying of the materials inside the oven.
Q:Can insulating fire bricks be used in the insulation of walls and roofs?
Insulating fire bricks excel in withstanding extreme heat and are primarily intended for high-temperature applications like kilns, furnaces, and fireplaces. However, they may not be the optimal choice for insulating walls and roofs. Although insulating fire bricks possess a high thermal resistance that effectively minimizes heat transfer, they fall short in terms of preventing air infiltration and delivering superior insulation compared to materials specifically designed for building insulation. When it comes to insulating walls and roofs, it is more customary to employ materials such as fiberglass, mineral wool, foam boards, or spray foam insulation. These materials boast superior insulating properties and are specifically engineered to offer thermal resistance, air sealing, and moisture control. If you are contemplating the use of insulating fire bricks for wall or roof insulation, it is crucial to seek advice from a professional who can assess your specific requirements and recommend the most suitable materials for your project.
Q:Are insulating fire bricks suitable for insulation in cryogenic applications?
Yes, insulating fire bricks are suitable for insulation in cryogenic applications. Insulating fire bricks have excellent thermal insulation properties, low thermal conductivity, and can withstand extremely low temperatures. This makes them ideal for use in cryogenic applications where insulation is required to maintain the low temperature of the system.
Q:Can insulating fire bricks be used in the construction of heat shields?
Certainly, heat shields can indeed be constructed using insulating fire bricks. These bricks are specifically designed to withstand elevated temperatures and possess exceptional thermal insulation properties. Their ability to effectively absorb and distribute heat makes them an ideal choice for the creation of heat shields, which serve to safeguard against excessive heat and mitigate thermal damage. In industries that involve high temperatures, such as steel, glass, and ceramics, insulating fire bricks are frequently employed. Moreover, their lightweight nature and ease of handling make them a practical option for constructing portable or easily installable heat shields. In summary, insulating fire bricks are a reliable and appropriate material for constructing heat shields in a diverse range of applications.
Q:Are insulating fire bricks suitable for use in blast furnaces?
Insulating fire bricks are not suitable for use in blast furnaces. Blast furnaces operate at extremely high temperatures, often exceeding 2000 degrees Celsius, and require refractory materials that can withstand such intense heat. Insulating fire bricks are designed to have low thermal conductivity, which means they are efficient at reducing heat transfer. However, this property also makes them vulnerable to damage and degradation in high-temperature environments. In blast furnaces, where molten iron and other materials are processed, the refractory lining needs to have high thermal shock resistance, good mechanical strength, and resistance to chemical corrosion. Therefore, specialized refractory materials, such as high-alumina or silica refractory bricks, are preferred for blast furnace linings due to their ability to withstand the extreme conditions and maintain structural integrity.
Q:Can insulating fire bricks be used in the construction of glass slump molds?
Yes, insulating fire bricks can be used in the construction of glass slump molds. Insulating fire bricks are made of lightweight materials that are able to withstand high temperatures, making them suitable for use in kilns and other heat-intensive applications. When constructing a glass slump mold, it is important to have a material that can withstand the heat of the glass as it slumps and takes shape. Insulating fire bricks provide the necessary insulation and heat resistance required for this process. They can be cut and shaped to fit the desired mold design and can withstand repeated firings without degrading or crumbling. Overall, insulating fire bricks are a reliable and durable option for constructing glass slump molds.
Q:Are insulating fire bricks resistant to flame spread?
Yes, insulating fire bricks are resistant to flame spread.
Q:Can insulating fire bricks be used in oil refineries?
Yes, insulating fire bricks can be used in oil refineries. These bricks are designed to withstand high temperatures and provide excellent insulation, making them suitable for various industrial applications, including oil refineries. They help to reduce heat loss, improve energy efficiency, and protect the surrounding equipment and structures from extreme heat.
Q:What is the exterior wall insulation material made of graphite?
Graphite polystyrene (SEPS) containing graphite particles special, can be like a mirror which contains thermal radiation, and can greatly enhance the heat insulation performance of the infrared absorption, thereby reducing the heat loss of housing. Its insulation capacity is at least 30% higher than the average EPS, helping to increase energy efficiency and reduce carbon dioxide emissions.
Q:Is it possible to repair damaged insulating fire bricks?
Yes, it is possible to repair damaged insulating fire bricks. The damaged bricks can be repaired by using refractory cement or mortar to fill in cracks or gaps. Additionally, damaged portions can be cut out and replaced with new bricks. However, the extent of the damage and the specific repair method required may vary depending on the severity of the damage.
