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.
After burning, the brick will be packed in pallet and leave the factory.

- Q: Can insulating fire bricks be used in high-temperature insulation panels?
- Yes, insulating fire bricks can be used in high-temperature insulation panels. Insulating fire bricks are designed to withstand and retain heat, making them an ideal choice for applications that require high-temperature insulation.
- Q: The insulation layer destroyed after use of cement paste and tiling
- Put on the insulating layer and paste it with cement.Some students worry about the insulation layer and the wall adhesive strength is not enough, do not worry about, now developers are building exterior insulation and then on top of the tiling. Because after finishing the insulation layer, the contractor should check the construction to do a pullout test, the purpose is to prevent the strength can not meet the requirements.
- Q: Can insulating fire bricks be used in drying ovens?
- Yes, insulating fire bricks can be used in drying ovens. Insulating fire bricks are designed to have low thermal conductivity, which makes them an excellent choice for applications that require heat insulation, such as drying ovens. These bricks can withstand high temperatures and provide insulation to help maintain the desired temperature inside the oven, while also reducing heat loss to the surroundings. Additionally, insulating fire bricks are lightweight and easy to install, making them a practical choice for use in drying ovens.
- Q: Are insulating fire bricks resistant to mold or mildew?
- No, insulating fire bricks are not resistant to mold or mildew. These types of bricks are specifically designed to withstand high temperatures and provide excellent insulation, but they do not possess any inherent resistance to mold or mildew growth. Mold and mildew can still develop on the surface of insulating fire bricks if they are exposed to moisture or damp conditions. To prevent mold or mildew growth, it is important to ensure that the bricks are kept dry and well-ventilated. Regular cleaning and maintenance can also help in preventing the growth of mold or mildew on the surface of insulating fire bricks.
- Q: Can insulating fire bricks be used in ceramic kilns?
- Yes, insulating fire bricks can be used in ceramic kilns. These bricks are designed to have high insulating properties, making them ideal for maintaining heat within the kiln. They are lightweight and can withstand high temperatures, making them a suitable choice for ceramic kilns.
- Q: What is the bulk density of insulating bricks?
- Stoneware porcelain water absorption rate is greater than 0.5% and less than or equal to 3%; fine stoneware bibulous rate is greater than 3% and less than or equal to 6%; brick bibulous rate is greater than 6% and less than or equal to 10%; pottery tile water absorption rate is greater than 10%. The water absorption rate of expression: ceramic brick brick >6% = >10% = >3% = fine stoneware porcelain stoneware or porcelain >0.5%
- Q: Can insulating fire bricks be used for insulation in boilers?
- Yes, insulating fire bricks can be used for insulation in boilers. These bricks are designed to withstand high temperatures and are highly effective in retaining heat, making them suitable for insulating the walls and floors of boilers.
- Q: Are insulating fire bricks resistant to cracking?
- Yes, insulating fire bricks are designed to be highly resistant to cracking. They are manufactured to withstand high temperatures and thermal shocks, ensuring their durability and preventing cracks from developing.
- Q: Are insulating fire bricks suitable for use in aluminum smelting furnaces?
- Insulating fire bricks are typically unsuitable for aluminum smelting furnaces as they are designed to retain heat rather than withstand extreme temperatures. Aluminum smelting requires temperatures exceeding 1,000 degrees Celsius, making refractory fire bricks or refractory castables more appropriate. These materials have high melting points and can endure the intense heat without compromising their structural integrity. They also possess excellent thermal shock resistance, which is crucial due to rapid temperature fluctuations in the furnace during operation. Furthermore, refractory materials used in aluminum smelting furnaces should exhibit resistance to corrosion and chemical attack from molten aluminum and other substances involved in the smelting process. Insulating fire bricks may lack the necessary chemical resilience, potentially resulting in premature degradation and failure of the furnace lining. In conclusion, although insulating fire bricks may be suitable for applications requiring thermal insulation, they are generally not recommended for use in aluminum smelting furnaces. Refractory fire bricks or refractory castables are better suited for this chemically aggressive and high-temperature environment.
- Q: Can insulating fire bricks be used in the construction of pottery kiln shelves?
- Yes, insulating fire bricks can be used in the construction of pottery kiln shelves. Insulating fire bricks are designed to withstand high temperatures and provide excellent insulation, making them an ideal material for kiln shelves. They can help maintain consistent heat distribution and prevent thermal shock, which is important for firing pottery. Additionally, insulating fire bricks are lightweight and easy to handle, making them a practical choice for constructing kiln shelves.
