Advantages of Ceramic Fire Board as Furnace Lining Material

Low Bulk Density

Ceramic sheet insulation has a lower bulk density, making the furnace lining structure lighter. It can reduce the stress of the furnace structure, thereby improving the safety and service life of the furnace.

Low Thermal Conductivity

Ceramic fiber board has a lower thermal conductivity. So, this can reduce the temperature outside the furnace. At the same time, it can also withstand higher temperatures without deformation or damage.

Excellent Thermal Shock Resistance

It can maintain structural stability when the furnace temperature changes sharply. That is to say, this helps to reduce the damage of the furnace lining material and extend the service life of the furnace lining.

High Efficiency

The construction of ceramic board insulation can adopt a modular design to achieve rapid installation and disassembly. Therefore, this greatly improves construction efficiency and reduces installation costs.

Good Machinability

At the same time, vacuum formed ceramic fiber board also has good machinability. Kerui can customize it according to the specific shape and size of the furnace to meet the needs of different users.

Strong Ready-to-Use

Compared with other furnace lining materials, ceramic fiberboard can be used directly without long-term furnace baking. This shortens the preheating time of the furnace and improves production efficiency.
