Refractory Bricks

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.

High alumina anchoring bricks, also known as anchor bricks or anchor blocks, are refractory bricks specifically designed for anchoring and securing the lining of industrial furnaces, kilns, and other high-temperature equipment. They play a crucial role in maintaining the integrity and stability of the refractory lining by providing mechanical support and resisting the forces of thermal expansion and contraction.

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.

Refractory porcelain balls Refractory balls are made of industrial alumina and refractory kaolin as the main raw materials, through scientific formula, shaping and high-temperature calcination. nature  

Low-creep clay bricks are now one of the commonly used refractory bricks in blast furnaces and hot blast furnaces, and as the wind temperature increases, the creep resistance of clay bricks increases. Low creep clay bricks are made of coke clinker with dense structure and high initial. And a few impurities as the main raw material, adding part of synthetic mullite and trilithon raw materials to configure into clay, which will be formed under high pressure, dried and fired at high temperature.

Clay bricks generally have an Al2O3 content of over 40% and an Fe2O3 content less than 2.0-2.5%. The raw material mixture consists of 65-85% clinker and 35-15% bonding clay. The crushed bonding clay and finely ground clinker are mixed and milled together, then formed under high pressure to produce a semi-dry mud. This mixture is fired at around 1400°C, resulting in good performance. Clay bricks exhibit a weak acidic nature at high temperatures and have a slightly lower resistance to alkaline slag erosion, but this ability improves with higher Al2O3 content. They have better thermal stability compared to silica bricks and magnesia bricks.

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%.
