In the glass production process, the insulation effect of the melting furnace, as the core thermal equipment, directly affects the quality of glass, energy consumption, and production costs. Calcium silicate board, as an excellent insulation material, plays an irreplaceable role in the insulation system of glass factory furnaces. Rosewool Insulation Refractory Co.,Ltd., with years of industry experience, now conducts a professional analysis of the application value of calcium silicate board in glass factory melting furnaces. The key function of calcium silicate board in glass melting furnace
Excellent thermal insulation performance
Calcium silicate board has an extremely low thermal conductivity (usually between 0.05-0.06W/m · K), which can effectively block the high temperature inside the furnace from transferring outward. At a working environment of around 1500 ℃, calcium silicate board can significantly reduce the surface temperature of the kiln body, reduce heat loss, improve thermal efficiency, and help glass factories achieve energy-saving and consumption reducing goals.
Excellent thermal stability
Glass melting furnaces require a stable temperature environment, and calcium silicate boards exhibit excellent performance here. Its coefficient of thermal expansion is small, making it less prone to cracking or deformation under rapid cooling and heating conditions, ensuring a stable distribution of temperature field in the melting furnace and providing reliable guarantee for the production of high-quality glass.
High strength and durability
Compared to traditional insulation materials, calcium silicate board has higher mechanical strength. Its compressive strength can reach over 0.5 MPa, and its flexural strength exceeds 0.3 MPa. It can withstand various stresses during the operation of the furnace, ensuring the long-term stability of the insulation layer structure.
Reliable construction performance
Calcium silicate board is easy to cut and install, and can be precisely processed according to the characteristics of the furnace structure to ensure a tight fit of the insulation layer. Its regular size and stable performance provide strong guarantees for the quality of furnace insulation engineering.
Specific application areas of calcium silicate board in glass melting furnaces
Furnace arch insulation
As a key component of the melting furnace, the insulation effect of the large arch directly affects energy consumption and kiln age. Calcium silicate board has become an ideal choice for large arch insulation due to its excellent thermal stability and insulation performance.
Pool wall insulation
At the pool wall where the glass liquid comes into contact, calcium silicate board can effectively reduce heat loss, maintain stable temperature of the glass liquid, and protect the steel structure from high temperature damage.
Thermal insulation of heat storage chamber
The insulation requirements for the heat storage system are strict, and calcium silicate board plays an important role in insulation, ensuring heat exchange efficiency and improving waste heat utilization.
Flue insulation
The insulation of the flue system is equally important, and calcium silicate board can effectively reduce the temperature loss of flue gas and improve the overall thermal efficiency of the system.
