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: How do insulating fire bricks affect the overall insulation efficiency of a process?
- The overall insulation efficiency of a process can be greatly enhanced by the use of insulating fire bricks. These bricks are specifically designed to have low thermal conductivity, making them excellent at resisting heat transfer. This property helps to minimize heat energy loss and maintain a consistent and controlled temperature within the process. The utilization of insulating fire bricks results in a significant reduction in the amount of heat that escapes from the process. This leads to improved energy conservation and ultimately, increased insulation efficiency. The bricks act as a barrier, preventing the conduction of heat through the walls, floors, or other components of the process equipment. This is particularly crucial in high-temperature applications, where heat loss can be substantial. Moreover, insulating fire bricks are capable of withstanding high temperatures without deteriorating or melting. This means that they can effectively insulate the process even when exposed to extreme heat conditions. Their durability ensures long-lasting performance and reliable insulation over time. Another advantage of insulating fire bricks is their lightweight nature. In comparison to traditional dense bricks, they have a lower density, which reduces the overall weight of the equipment or structure. This not only simplifies the construction process but also minimizes the load on supporting structures. In conclusion, insulating fire bricks enhance the overall insulation efficiency of a process by reducing heat loss, maintaining a controlled temperature, and providing long-lasting insulation capabilities. Their low thermal conductivity, resistance to high temperatures, and lightweight properties make them an ideal choice for various industrial applications where energy conservation and efficient insulation are crucial.
