Refractory Brick
Refractory brick can be divided into three process: Raw material, molding, burning.Generally, refractory brick was molded by dry pressing. By means of mixing the material uniformity in proportion and aging mixture some time. Then, pour some powders into the module and dry pressing. After dry pressing, the adobe need to pushed in the drying kiln to stoving or stay in the air to drying. This progress will need about 3-5 days. After this progress, then push the adobe into the tunnel furnace or shuttle kiln to burning around 1300C. This progress will be need about 5-7 days.

- Q:Are insulating fire bricks resistant to impact or mechanical stress?
- Indeed, insulating fire bricks exhibit resistance against impact and mechanical stress. These bricks are crafted using lightweight refractory materials, purposefully formulated to endure extreme temperatures and thermal shock. Their composition is specifically engineered to possess exceptional resilience against mechanical stress and impact, rendering them appropriate for a multitude of applications in which external forces or pressure may be exerted upon them. Remarkably, these bricks retain their structural integrity and durability, safeguarding their shape and thermal insulation attributes even when subjected to mechanical stress or impact. Consequently, they are highly recommended for deployment in furnaces, kilns, and other environments characterized by elevated temperatures.
- Q:Are insulating fire bricks suitable for use in the construction of incinerators?
- Insulating fire bricks prove to be a suitable option for constructing incinerators. They are specifically designed to endure high temperatures and possess exceptional insulation properties. Incinerators operate at extremely high temperatures, often surpassing 1000 degrees Celsius, and require materials that can withstand such intense conditions without cracking or deteriorating. Made from lightweight refractory materials like ceramic fibers or lightweight aggregates, insulating fire bricks possess low thermal conductivity. Consequently, they effectively insulate the incinerator, preventing heat escape and maximizing energy efficiency. Moreover, the insulation properties of these bricks aid in maintaining a consistent temperature inside the incinerator, which is crucial for proper combustion and waste disposal. Furthermore, insulating fire bricks exhibit remarkable resistance to thermal shock, enabling them to withstand repeated cycles of heating and cooling without sustaining damage. This attribute is particularly vital in incinerators, where the temperature can rapidly fluctuate during the burning process. The bricks' capacity to endure thermal shock guarantees their durability and longevity in this high-temperature environment. Apart from their insulation and thermal shock resistance, insulating fire bricks offer additional advantages for incinerator construction. They possess a lightweight nature, facilitating easier handling and transportation during the construction phase. Furthermore, they can be readily cut or shaped to fit specific designs or requirements, allowing for flexibility in incinerator construction. In conclusion, insulating fire bricks stand as an ideal choice for incinerator construction due to their resistance to high temperatures, insulation properties, thermal shock resistance, durability, and ease of use. They provide a reliable and efficient solution for containing and maintaining the intense heat generated in incinerators, ensuring the safe and effective disposal of waste.

- Insulating fire bricks do not possess specific resistance against insect infestation. They are primarily utilized for their thermal insulation properties in applications involving high temperatures, such as kilns, furnaces, and fireplaces. Although they are generally not prone to insect damage, they are not entirely impervious to it either. Insects can still infiltrate the bricks if they discover small cracks or openings in the material. Nevertheless, insulating fire bricks are typically dense and compact, thereby making it challenging for insects to burrow or establish nests within them. It is always advisable to employ preventive measures for managing and eliminating potential insect infestations in any construction material, including insulating fire bricks, to ensure their durability and effectiveness.
- Q:Can insulating fire bricks be used in the construction of heat storage systems?
- Insulating fire bricks have the potential to be utilized in the construction of heat storage systems.

By incorporating insulating fire bricks, it becomes feasible to minimize heat loss, thereby facilitating efficient heat storage and retention within the system. These bricks can be employed to construct the walls and lining of the heat storage system, ensuring that the stored heat does not dissipate into the surroundings. Furthermore, insulating fire bricks are lightweight and easily manageable, rendering them a convenient option for the construction of heat storage systems. Ultimately, the utilization of insulating fire bricks significantly enhances the thermal efficiency of heat storage systems, consequently contributing to more effective heat management.
- Q:Do insulating fire bricks have low thermal conductivity?
- Insulating fire bricks possess a low thermal conductivity, ensuring minimal heat loss and outstanding insulation capabilities. Their composition, usually incorporating lightweight elements like clay, silica, and alumina, accounts for their reduced thermal conductivity. Consequently, these materials are inefficient at transferring heat. Consequently, insulating fire bricks effectively curtail heat transfer, thus preserving elevated temperatures within a structure. Hence, they are an excellent choice for high-temperature insulation needs, exemplified by their suitability for kilns, furnaces, and fireplaces.
