Cold Crushing Strength 20 to 40 MPa Clay Refractory Brick Featuring Chemical Composition Al2O3 30 to 45 Percent and Plc Greater Than 1280 Degrees Celsius

Product Description:

The Clay Refractory Brick is a highly durable and efficient material specifically designed for use in high-temperature environments such as reheating furnaces. Known commonly as Clay Firebrick or Refractory Clay Bricks, these bricks are essential components in furnace construction and maintenance, providing excellent resistance to heat, corrosion, and mechanical wear. Their primary application is as furnace liners, where they play a critical role in protecting the furnace structure from extreme temperatures and thermal shock.

One of the key features of Clay Firebrick is its ability to withstand very high temperatures, with a permissible limit of ≥1280℃. This makes it ideal for use in reheating furnaces, where temperatures often reach intense levels during the processing of metals and other materials. The bricks ensure the furnace operates efficiently by maintaining thermal insulation and preventing heat loss, thereby contributing to energy savings and enhanced operational performance.

The chemical composition of these Refractory Clay Bricks is carefully formulated to optimize their heat-resistant properties. They typically contain 30-45% alumina (Al2O3), which provides excellent strength and thermal stability. Additionally, the silica content (SiO2) ranges from 50-65%, contributing to the brick’s ability to resist thermal expansion and contraction, reducing the risk of cracking and structural failure. The iron oxide (Fe2O3) content is kept below 2%, ensuring minimal impact on the brick’s refractory qualities and color consistency.

Clay Firebrick is available in both standard sizes and customized dimensions, allowing it to meet the specific requirements of different furnace designs and applications. This flexibility ensures that the bricks can be seamlessly integrated into various furnace configurations, providing a perfect fit and optimal protection. Customization options also enable clients to select bricks with specific physical properties or shapes to enhance furnace efficiency and longevity.

In addition to their thermal resistance, these Refractory Clay Bricks exhibit excellent mechanical strength and durability. They are capable of withstanding the harsh conditions inside reheating furnaces, including thermal cycling, abrasion, and chemical attack from slags and gases. This durability minimizes maintenance needs and extends the service life of the furnace lining, resulting in cost savings and reduced downtime for industrial operations.

The manufacturing process of Clay Firebrick involves the careful selection and processing of natural clay materials, followed by high-temperature firing to achieve the desired refractory properties. This process ensures that each brick has uniform density, strength, and resistance to thermal shock. The quality control measures during production guarantee that the bricks meet stringent industry standards and perform reliably under demanding conditions.

Overall, Clay Firebrick, or Refractory Clay Bricks, are indispensable materials in the construction and maintenance of reheating furnaces. Their superior heat resistance, mechanical strength, and customizable sizes make them ideal for furnace liners, ensuring the protection and efficiency of high-temperature industrial processes. With a chemical composition balanced to optimize performance and a high melting point of ≥1280℃, these bricks are engineered to meet the rigorous demands of modern metallurgical and manufacturing industries.

Choosing Clay Firebrick for furnace lining applications not only enhances the durability and thermal efficiency of reheating furnaces but also contributes to safer and more sustainable industrial operations. Their proven performance and adaptability continue to make them a preferred choice among engineers and industry professionals worldwide.
