Refractory Bricks

Magnesia chromite bricks are a type of refractory brick that is commonly used in high-temperature applications, such as in steel, non-ferrous metal, and glass industries. These bricks are known for their excellent resistance to corrosion and high thermal stability. 

High alumina brick is a kind of refractory material. The main component of this refractory brick is Al2O3. If the Al2O3 content is higher than 90%, it is called corundum brick. Due to different resources, national standards are not completely consistent. For example, European countries stipulate that the lower limit of Al2O3 content for high-aluminum refractory materials is 42%. In China, high alumina bricks are usually divided into three grades according to their Al2O3 content: Grade I - Al2O3 content >75%; Grade II - Al2O3 content 60-75%; Grade III - Al2O3 content 48-60%.

Silica brick is an acidic refractory material mainly composed of tridymite, cristobalite and a small amount of residual quartz and glass phases. Silica content is more than 94%. True density 2.35g/cm3. Resistant to acidic slag erosion. Higher high temperature strength. The load softening starting temperature is 1620~1670℃. It will not deform after long-term use at high temperatures. Thermal shock stability is low (heat exchange in water is 1 to 4 times). It uses natural silica as raw material, plus an appropriate amount of mineralizing agent to promote the transformation of quartz in the green body into tridymite. It is slowly fired at 1350~1430℃ in a reducing atmosphere. When heated to 1450°C, there will be a total volume expansion of about 1.5~2.2%. This residual expansion will make the seams close and ensure good air tightness and structural strength of the masonry.

Silicon bricks, also known as silica bricks or silicon carbide bricks, are a type of refractory material commonly used in glass kilns and other high-temperature applications. They are made primarily from silica (SiO2), which is a key component of sand and quartz.

It is mainly used for the partition walls of the carbonization chamber and combustion chamber of coke ovens, the regenerators and slag chambers of steel-making open-hearth furnaces, soaking furnaces, refractory materials of glass melting furnaces and ceramic firing kilns, and other kiln vaults. Load-bearing parts. It is also used in high-temperature load-bearing parts of hot blast furnaces and acidic open-hearth furnace tops.

Refractory magnesia brick, often referred to as magnesite brick or magnesia refractory brick, is a type of refractory material made primarily from magnesia (magnesium oxide, MgO) as the main component. Magnesia bricks are known for their high refractoriness and excellent resistance to high temperatures.

Highumina Runner Brick refers to a type of refractory brick that is designed specifically for use in the runners and channels of metal casting systems, such as in foundries and steel plants. These bricks are made from high-purity alumina or high-alumina raw materials, which offer excellent heat resistance and thermal stability.

High alumina arc brick, also known as high alumina arch brick, is a type of refractory brick that is designed for use in high-temperature applications such as industrial furnaces, kilns, and other thermal equipment. These bricks are made from high-grade raw materials, consisting of high alumina content, and are manufactured using a specialized process to ensure high heat resistance and durability.

High alumina checker bricks, also known as checkerwork bricks or regenerator checker bricks, are specialized refractory bricks used in regenerators of certain types of industrial furnaces, such as regenerative thermal oxidizers (RTOs) and regenerative glass melting furnaces. These bricks are designed to optimize heat exchange and energy efficiency by alternating hot and cold gas flows in the regenerator system.

Phosphate high alumina brick, also known as phosphate-bonded high alumina brick or chemically bonded high alumina brick, is a type of refractory brick that is made by combining high-purity alumina with a phosphate-based binder. The binder reacts with the alumina at elevated temperatures to form a chemically bonded matrix, providing cohesion and strength to the brick.
