Fire Clay Insulating Bricks: Distinguishing Differences Between SK34 and SK36

Nov 20, 2023

SK34 and SK36 fire clay insulating bricks are essential materials in high-temperature applications, offering thermal insulation and protection against extreme heat. By understanding their properties, applications, and key differences, professionals can make informed decisions when selecting the most suitable fire clay insulating bricks for their specific requirements.

Understanding Fire Clay Insulating Bricks

Fire clay insulating bricks are refractory bricks manufactured from a blend of fire clay and other materials, such as grog, alumina, and silica. They are designed to withstand high temperatures, provide thermal insulation, and protect against thermal shock and chemical corrosion.

Applications of SK34 and SK36 Fire Clay Insulating Bricks

SK34 Fire Clay Insulating Bricks:

Suitable for applications where thermal insulation and moderate strength are required.

Commonly used in industrial furnaces, kilns, and boilers.

Ideal for lining chimneys, flues, and other high-temperature ducts.

SK36 Fire Clay Insulating Bricks:

Preferred for applications demanding higher strength and thermal insulation.

Widely used in glass and ceramic industries for furnace construction and kiln linings.

Suitable for high-temperature applications in the metallurgical and chemical industries.

Key Differences Between SK34 and SK36 Fire Clay Insulating Bricks

Density and Strength: SK36 refractory bricks fire clay brick have a higher bulk density and compressive strength compared to SK34 bricks. This makes them more suitable for applications requiring higher mechanical strength and resistance to physical stress.

Thermal Conductivity: SK34 bricks exhibit slightly lower thermal conductivity than SK36 bricks. This property makes SK34 bricks more efficient in providing thermal insulation and reducing heat loss.

Maximum Service Temperature: SK36 fire clay insulating brick have a higher maximum service temperature compared to SK34 bricks. They can withstand temperatures up to 1350°C, making them suitable for more demanding high-temperature applications.

Factors To Consider When Choosing Fire Clay Insulating Bricks

Application Requirements: Consider the specific requirements of the intended application, including temperature range, mechanical strength, and thermal insulation needs.

Compatibility: Ensure that the chosen fire clay insulating bricks are compatible with the existing refractory system and the materials being processed.

Quality and Standards: Opt for fire clay insulating bricks that meet industry standards and are manufactured by reputable suppliers to ensure reliability and durability.
