What Are Refractory Bricks?
Refractory bricks for sale are an inorganic non-metallic material, which shows excellent resistance to the effects of heat, without undergoing deformation, melting, or deterioration. What’s more, the term “refractory” precisely defines their ability to withstand high temperatures. Refractory bricks commonly consist of fire clay, high alumina, silica, magnesia, or chrome, each composition offering distinct properties for different industrial requirements. Besides, high-temperature refractory bricks are available in a variety of shapes and compositions to achieve optimal performance in diverse industrial settings.
Properties of Refractory Brick
Specifications of Refractory Bricks
The density of refractory brick means the mass per unit volume of the brick and is typically measured in grams per cubic centimeter (g/cm³). According to the type and composition, the density can range from 1.9 g/cm³ to 4.0 g/cm³.
The apparent porosity of refractory bricks for sale refers to the number of open pores or voids in the brick. Meanwhile, porosity affects the brick’s thermal insulation properties and reach the high porosityof over 45%.
It indicates the ability of the brick to conduct heat. Besides, lower thermal conductivity values indicate better insulation properties.Thus, it represents the maximum compressive load a brick can withstand without breaking.
Alumina is a common component in refractory bricks. The Al2O3 content can range from low (around 20%) to high (over 90%), which is decided by the desired refractory properties.
Silica is another important constituent of refractory bricks. The SiO2 content can vary and affect the thermal and chemical resistance of the refractory bricks.
Refractory bricks may contain additional components such as magnesia (MgO), zirconia (ZrO2), chrome (Cr2O3), and carbon (C) to enhance specific properties.
Dimensions of Refractory Brick
Dimensions of refractory brick can be divided into standard refractory bricks, custom custom-shaped refractory bricks. Meanwhile, special refractory brick sizes need to be determined according to the customer’s construction needs. If you have a project under construction, please contact us!
Standard Refractory Bricks
Standard refractory bricks are a common standard because they meet certain established norms, specifications, and quality standards: 230*114*65. Kerui has many standard bricks in stock
Straight Refractory Bricks
Straight refractory bricks also called rectangular/square refractory bricks, which has a rectangular or square shape and are commonly used for lining straight walls and floors.
Wedge Refractory Bricks
Wedge refractory bricks are narrower at one end and wider at the other. Meanwhile, they are suitable for constructing arched structures, such as kiln roofs or furnace crowns.
Anchor Refractory Bricks
Anchor refractory bricks are designed to anchor or hold the refractory lining in place to maintain structural stability. So they are typically used as linings for the high-temp industry.
Special Dimensions Brick
Refractory material manufacturers can customize refractory bricks to fit specific installations, such as curved refractory bricks, large refractory bricks, and other types of refractory bricks.
Common Applications of Refractory Bricks for Sale
Refractory bricks have extensive applications in the steel industry, particularly in blast furnaces, ladles, and steel-making converters. Meanwhile, refractory bricks line the walls and floors of these structures to withstand the intense heat and chemical reactions involved in steel production.
High temperature refractory bricks provide insulation and high-temp resistance to ensure the efficient and continuous production of the Glass industry. Meanwhile, AZS brick is suitable for glass-melting furnaces to prevent excessive heat from damaging the structure and maintain thermal efficiency.
Refractory bricks play an important role in cement kilns. For example, Refractory bricks in the burning zone of the kiln need to withstand the highest temperatures. Thus, they can protect the kiln shell and maintain the desired thermal conditions for clinker formation.
In refineries and petrochemical plants, high-temperature refractory bricks are suitable for cracking units, reformers, and reactors. In addition, refractory bricks provide insulation and chemical resistance to contain corrosive substances and maintain stable operating conditions.
Refractory bricks are suitable for use in boilers, furnaces, and incinerators within power plants. Meanwhile, high-temperature refractory bricks can withstand the high temperatures generated by burning coal, oil, or natural gas, ensuring efficient energy production.
Industries dealing with non-ferrous metals, such as aluminum, copper, and zinc, utilize refractory bricks in smelting furnaces, anode baking furnaces, and other high-temperature applications.
