Simple Introduction of High Temperature Fire Bricks
High temperature fire bricks, also known as refractory bricks or firebricks, are a kind of inorganic non-metallic material. Besides, the bricks typically exhibit a light yellow or brownish hue. Notably, they demonstrate exceptional resistance to high temperatures, which can withstand ranges between 1250-1790℃(2282-3254℉). Meanwhile, they primarily consist of refractory clay and other refractory raw materials. At Kerui, these fire bricks are available in a variety of sizes and chemical compositions to achieve optimal performance in diverse industrial settings.
Main Types of Kerui High Temperature Fire Bricks
According to their different chemical compositions and sizes, Kerui divides high temperature bricks into many types. So this part will briefly introduce the main types of Kerui high temperature fire bricks for you.
Different Chemical Compositions of High Temperature Fire Bricks
Al-Si Fire Bricks
Al-Si fire bricks typically consist of Al2O3 and SiO2. At the same time, the precise ratio of these components can vary depending on the desired properties of the bricks. Meticulously engineered to endure extreme temperatures and harsh environments, these bricks find purpose across diverse industrial applications. Thus, these bricks occupy a very important position in the refractory application fields. The Al-Si high temperature fire bricks provided by Kerui include:
- High Alumina Brick
- AZS Bricks
- Corundum Brick
- Mullite Brick
- Fire Clay Brick
- Silica Brick
- Silicon Carbide Brick

Magnesia Fire Bricks
Magnesia fire bricks refer to refractory products mainly composed of basic oxides such as MgO. These bricks feature a composition that includes magnesium oxide and periclase as the predominant crystal phase. Besides, the periclase crystal demonstrates an exceedingly high melting point that can reach temperatures of up to 2800℃ (5072℉). Consequently, the refractoriness of magnetic firebricks surpasses that of general fire bricks. The Magnesia fire bricks provided by Kerui mainly include :
- Magnesia Brick
- Magnesia Chrome Brick
- Magnesia Carbon Brick
- Magnesia Alumina Spinel Brick
- Magnesia Iron Spinel Brick

Excellent Properties of Kerui Fire Brick
Kerui carefully selects great raw materials for high-temperature fire bricks. Generally, these materials include high-alumina aggregates, silica and other refractory compounds that inherently possess excellent heat resistance properties. Besides, most fire bricks have a high alumina content, which significantly contributes to their heat resistance.
By utilizing an automatic batching system, Kerui carefully formulates the mix of raw materials which can balance heat resistance with mechanical strength. Additionally, it pays attention to the distribution of grain sizes within the high-temp fire bricks. A uniform distribution contributes to better production of mechanically stable brick.
Kerui prudently opts for raw materials renowned for their remarkable chemical resistance. Among these materials are high-alumina aggregates and specialized clay, which have the inherent ability to withstand chemical corrosion. Meanwhile, Kerui often carries out inspections of fire bricks for chemical resistance in various environments to safeguard their durability.
High temperature fire bricks usually have a void structure. Besides, these interconnected small holes can effectively act as thermal shock absorbers. With the help of these holes, the bricks are able to dissipate stress. So this helps reduce the rate at which heat is conducted through the brick during temperature changes greatly.
Kerui high temperature fire bricks have a dense structure. Because of careful compacting, Kerui Group realizes this dense structure during production, which further minimizes the presence of open pores. Therefore, this low porosity minimizes heat loss through the brick, which is crucial for maintaining the efficiency of high-temperature equipment.
Kerui always implements the requirements of green development. While improving product quality, it takes responsibility for protecting the environment. For that, Kerui adopts all kinds of environmentally friendly refractories. As a result, during the application of high-temperature bricks, the release of the harmful substance can be at the lowest level.
Do You Know The Usages of High Temperature Fire Bricks?
High temperature bricks are suitable for the steel furnace refractory, particularly in blast furnaces, ladles and steel-making converters. So these bricks line the walls and floors of these structures to withstand the intense heat and chemical reactions involved in steel production.
These fire bricks are also suitable for glass-melting furnaces, especially in the lining of the glass-melting furnace, the side walls of the melting furnace, the inner wall of the combustion chamber, etc. Because the bricks can prevent excessive heat from damaging the structure and maintain thermal efficiency.
Because of high-temperature resistance, the bricks ensure the efficient and continuous production of the cement industry. So they play an important role in cement kilns, such as walls of cement kilns, lining of rotary kilns, preheating zone masonry, firing zone, etc.
In refineries and petrochemical plants, high-temperature fire bricks are used in cracking units, reformers and reactors. Because they provide insulation and chemical resistance to contain corrosive substances and maintain stable operating conditions.
In combustion chambers, boilers, steam burners, furnaces and incinerators within power plants, high temp fire bricks can withstand the high temperatures generated by burning coal, oil, or natural gas. So they ensure efficient energy production.
