As a high-performance furnace lining material, ceramic fiber insulation board has been widely used in the industrial field in recent years. It has many advantages and provides a strong guarantee for the safe and stable operation of the furnace.
In order to meet the needs of different customers, Kerui provides fireproof ceramic fiber board or calcium silicate insulation board of various specifications and models. The refractory ceramic fiber boards thickness ranges from 10mm to 100mm and the density ranges from 250kg/m³ to 360kg/m³. Customers also can choose the appropriate ceramic refractory insulation board according to the specific application scenario. Moreover, we can also make it into strip profiles and composite profiles according to user needs.

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.
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.
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.
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.
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.
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.
The specific industrial applications of refractory ceramic insulation sheets and boards mainly include the following aspects:
Expansion joints, backing insulation, insulation sheets and mold insulation;
Low price: as the direct source of calcium silicate board suppliers, Kerui has an independent production workshop. There is no middleman, so we can supply products at a more competitive price.
Spot supply: we have an independent storage warehouse with sufficient stock all year round to ensure fast direct delivery service.
Excellent quality: Kerui has more than 20 years of professional experience in the field of thermal insulation. Therefore, the quality of our products is trustworthy.
Extensive cooperation: we maintain long-term cooperation with more than 500 well-known companies around the world. For example, RUSAL, SUNSTONE, XING DA STEEL CORD (THAILAND) COMPANY LIMITED, SHANDONG WEIQIAO VENTURE CO., LTD., etc.
Quick quotation: we can provide reasonable solutions according to the needs of customer projects and provide quotation services quickly.
Professional technical support: according to the specific project needs, Kerui provides professional technical guidance for on-site installation.
Pre-sales and after-sales services: we provide comprehensive pre-sales consultation and after-sales services. For example, kiln refractory material selection and logistics arrangements. We ensure that customer needs are met in a timely manner.
Project bidding support: Kerui Refractory also provides full support and assistance for project bidding to ensure a smooth bidding process.
