Features of Kerui Insulation Bricks
Kerui insulating fire bricks have a high porosity, which means that it has many small holes inside. This is because of its advanced production technology. The high porosity ensures that the product performance meets the expected standards, such as low density, low thermal conductivity and good thermal insulation.
The insulating bricks have a low thermal conductivity and it can prevent heat from escaping or entering. This can better store heat and save energy for the customer’s project. For example, in a furnace or kiln, Kerui insulation brick can reduce heat loss and maintain a stable temperature. This can lower the fuel consumption and emission.
High mechanical strength of insulating refractory brick makes it can resist compression and bending forces. This is because of high-quality raw material as well as advanced production technology. In other words, the high mechanical intensity ensures that the product has a long service life and can withstand various harsh environments.
Kerui insulation bricks have a good insulation effect, which means that they can keep the heat or cold inside or outside. This is because of its low thermal expansion coefficient, which means that it does not change its shape or size when heated or cooled. If you need more insulation bricks, please follow Kerui YouTube.
Application Fields of Insulation Bricks
Apply Insulation Brick in Various Industries
The insulation bricks can be applied in various industries that need high-temperature resistance and thermal insulation, such as metallurgy, chemical, ceramic, glass, cement, power, and petrochemical industries. Meanwhile, Kerui insulating bricks can help these industries improve their production efficiency, reduce their energy consumption, and protect their equipment from damage. Insulation bricks can also improve product quality and performance by maintaining a stable temperature and preventing heat loss.
Apply Insulation Brick in Various Parts of Kilns
Insulation bricks can be applied in various parts of kilns, such as the lining, the roof, the wall, the door, the arch, the flue, the chimney, and the regenerator. Customers can use insulation firebrick to get thermal insulation and heat preservation for kilns. Also, this brick can prevent heat transfer and heat dissipation. Kerui insulation bricks can also reduce the thermal expansion and contraction of kilns, and prevent cracking and deformation. Kerui bricks are able to extend the service life of kilns and reduce maintenance costs.
