Importance of Refractory Bricks
Refractory bricks, also known as fire bricks, are essential materials for high temperature environments. They have high fire resistance, excellent creep resistance, shock resistance and corrosion resistance, and can resist high temperature erosion and chemical corrosion. Therefore, refractory bricks are often used in the construction of high-temperature equipment and furnace linings, such as aluminum melting furnaces, blast furnaces, trolley furnaces and glass kilns. Refractory bricks are widely used in industries such as metallurgy, construction, chemicals and power.
Refractory properties of refractory bricks
Refractory bricks are called fire bricks because they have extremely high refractory temperatures. The refractory temperature of general refractory bricks can reach 1790℃, while some high-quality refractory bricks such as magnesia bricks and corundum bricks can even reach 2000℃. This excellent high-temperature tolerance makes it an indispensable basic material for the high-temperature industry. By improving the refractoriness of refractory bricks, it can support the smelting of higher melting point materials and promote the development of the high-temperature industry.
Types and selection of refractory bricks
There are many ways to classify refractory bricks. According to different sizes, they can be divided into several grades. According to different ingredients, refractory bricks are divided into aluminum silicon refractory bricks, alkaline refractory bricks, carbon refractory bricks, magnesium refractory bricks, etc. There are many types of refractory bricks on the market, reaching more than 100 kinds. Therefore, when purchasing, you need to choose reasonable refractory bricks according to specific usage requirements.
In actual use, in addition to meeting the required refractory temperature, it is also necessary to consider the corrosion resistance of the environmental medium, the creep resistance in high temperature environment, and the seismic resistance under severe vibration. For example, in the steel smelting process, refractory bricks are needed to withstand high temperatures; in the chemical industry, high-temperature reactors are also an important application area for refractory bricks.
Other names and specific uses of refractory bricks
In addition to being called fire bricks, different types of refractory bricks may also have some specific nicknames, which are usually related to their materials, uses or special production processes. For example, high-alumina bricks, dolomite bricks, etc. Each type of refractory brick plays an important role in its specific application scenario and is an important guarantee for ensuring the stable operation of high-temperature industry facilities.
Therefore, refractory bricks play a key role in supporting and promoting the development of the high temperature industry. Without refractory bricks, it is difficult to ensure the stability and safety of the kiln's working environment. It is not only the cornerstone of the high temperature industry, but also an important boost to promote the progress of the industry.
