Fireramo Low Porosity Fire Clay Brick Description
High-density fireclay brick is a clay refractory brick product made from high-quality clay and clinker by mixing, molding, drying, and sintering. High-density fireclay brick’s porosity can be as low as 12%, which makes it difficult for the refractory brick itself to absorb water or other liquids, and at the same time, it has excellent performance in high temperature resistance. Low-porosity refractory bricks are very suitable for use in high-temperature and harsh conditions, such as steel, non-ferrous metals, glass, cement, and other fields, and play an extremely important role in the production and development of the high-temperature industry.
Benefits of Fireramo High Density Clay Bricks
Low porosity: The porosity of low-porosity fireclay bricks is usually less than 17%, which makes their structure denser and more resistant to erosion, effectively prolonging their service life.
High alumina content: Fireramo’s different types of fireclay bricks contain high alumina content, which ensures their excellent refractory and slag resistance properties.
Refractoriness: Fireramo’s low-porosity refractory clay bricks are fired at high temperatures and finely processed. The products have excellent compressive and flexural strengths and are able to withstand high temperatures, high pressures, and other harsh working environments. However, they are less resistant to alkalis.
Mechanical Strength: Low-porosity fireclay has good mechanical strength and is suitable for a variety of industrial equipment in high-temperature environments.
Applications of Fireramo High-Density Fireclay Bricks
Lower and middle grills and support arches of hot blast furnaces in large blast furnaces.
In the heat storage chambers of glass kilns because of its resistance to spalling.
Various high-temperature industrial kilns, such as lime kilns and steel ladles.
