Simple Introduction of High Temp Fire Brick

High-temperature fire bricks, as the name suggests, can be used in high-temperature environments and can be directly exposed to flames. Kerui fire bricks can withstand temperatures up to 1900°C (3452℉) in kilns.

The high temperature resistant properties of this brick are due to its high quality raw materials. Meanwhile, main components of Kerui refractory bricks are refractory clay and other chemical components such as Al2O3, SiO2, MgO and so on. With accurate ratio and advanced technology, Kerui produces high-quality high temp fire bricks. Customers who are in need can buy fire bricks from Kerui directly.

High-Temp Fire Bricks of Different Chemical Compositions

Al-Si High Temp Fire Bricks

Main types: high alumina brick, mullite brick, corundum brick, AZS brick, silica brick, silicon carbide brick…

Features: Al-Si fire bricks is mainly made of Al2O3 and SiO2. This kind of brick usually contains high purity of materials, which results in higher refractoriness and longer service life. Besides, Al-Si high heat fire brick has wide applications because of its superior chemical corrosion property. After improvements, Kerui also offers AZS brick that can withstand high temperature glass melt. According to different compositions and manufacturing processes, customers can find suitable fire bricks for their kilns.

Magnesia High Temp Fire Bricks

Main types: magnesia refractory brick, magnesia calcium brick, magnesia chrome brick, magnesia carbon brick, magnesia spinel brick…

Features: magnesia fire bricks use MgO as main material, and it also adds other chemical compositions to enhance some properties. Generally, magnesia fire brick belongs to basic refractory material. It has good resistance to basic chemical corrosion. Besides, magnesia brick has extremely high refractoriness due to good materials and excellent manufacturing process. Kerui magnesia bricks are the first choice of customers who plant to build cement kiln, steel and iron kiln, non ferrous melting kiln and so on.

High Temp Fire Bricks with Different Shapes

Standard High Temp Brick

Standard brick: 230×144×65mm.

The standard brick can be universally applied to the needs of various industries.  By the way, if you need high temp fire bricks urgently, Kerui has enough stock of standard fire bricks to ship in time.

Common Special-shaped High Temp Brick

Common special-shaped brick: skew brick, side arch brick, end arch side, key brick, etc.

In addition to standard size, there are also more common shaped bricks here. Various shapes of fire resistance bricks are supplied for you. As a result, this will save costs by reducing the number of blocks and joints.

Custom High Temp Brick

Custom brick: custom high temp fire bricks in shape, color, and size.

If you have special needs, Kerui can produce specific shapes of bricks according to the drawings you provide. Due to the automatic control system and professional groups, Kerui can easure the dimensional accuracy of brick. Meanwhile, it will take several days for custom bricks to come out of the kiln. Kerui promises to be able to deliver on time as agreed.

Good Properties of Fire Brick

High-Temperature Resistance

High temp fire bricks are usually made from a combination of alumina, silica, zirconia, magnesia, and other oxides. These compounds inherently have high melting points to withstand the intense heat generated in high-temperature industries. Meanwhile, the mineral elements in the raw materials undergo a liquid phase transition during sintering, forming a high-temperature-resistant crystal phase. So Kerui’s high temp refractory bricks have excellent capacities for temperature resistance.

Mechanical Strength

High temp fire bricks have a good performance on compressive strength and are wear-resistant. So the bricks are not easily damaged at high-temperature under high temperatures and high-strength environments. During the firing process, the particles in the fire bricks are tightly packed together. Thereby it improves the mechanical strength. Kerui’s need to inspect fire bricks strictly to ensure that the mechanical properties of the bricks meet the expected values.

Chemical Resistance

Due to the low porosity and high density of firebricks, the penetration of liquids and gases into the bricks can be minimum. Therefore, it can reduce the possibility of chemical reactions in bricks. The Al2O3 contained in the high heat fire bricks forms a stable alumina layer on the surface that protects the underlying material from further chemical attack. This makes the high temp fire bricks have good chemical stability and strong corrosion resistance.

Thermal Shock Resistance

High temp fire bricks usually have a void structure. These interconnected small holes can effectively act as thermal shock absorbers. With the help of these holes, the bricks are able to dissipate stress. Meanwhile, they have low thermal conductivity, which makes them inefficient at transferring heat. This feature helps reduce the rate at which heat is conducted through the brick during temperature changes greatly. So the refractory brick has excellent thermal shock resistance.

Wide Applications of High Temperature Fire Brick

Kerui – Experienced High Temp Fire Brick Manufacturer

Compliant High Temp Fire Brick

Kerui promises to supply top-quality high temp fire bricks. On the one hand, the modern production system guarantees the consistent quality of refractory bricks. Due to the help of the automatic batching system, Kerui uses a microcomputer to control the ratio of raw materials. On the other hand, Kerui holds 20 sets of 400-ton CNC presses and 2 1000-ton hydraulic presses, and two 168-meter high-temperature natural gas tunnel kilns. This advanced equipment can greatly increase production efficiency. Meanwhile, regular inspections in physical and chemical labs guarantee the performance of bricks.
