High Density Low Porosity Refractory Firebrick High Alumina Brick
High Density Low Porosity Refractory Firebrick High Alumina Brick
Description
High density high alumina bricks are commonly used in high-temperature applications, such as in furnaces, kilns, and other thermal processing equipment. They are also used in various industrial applications where there is a need for high resistance to wear, corrosion, and chemical attack.
These bricks are produced through a process of dry pressing or extrusion, followed by high-temperature firing in a kiln. The high temperature firing process ensures that the bricks have a low porosity and a high density, which makes them ideal for use in harsh industrial environments.
High density high alumina bricks come in a range of sizes and shapes, and they can be custom-designed to meet specific application requirements. They are also available with different levels of alumina content, ranging from 50% to 99%, depending on the specific application.
