Refractory brick is a kind of high-temperature refractory material, usually used in the construction and maintenance of high-temperature hearths, kilns, chimneys and other industrial equipment. It is made from a variety of refractory materials through a certain proportion of mixing, moulding, drying, sintering and other processes, and has excellent properties such as high temperature resistance, chemical corrosion resistance and wear resistance. The following is a detailed introduction to refractory bricks:
Classification of refractory bricks
According to the different characteristics of refractory bricks such as material, structure and use, refractory bricks can be divided into various types, such as clay refractory bricks, high alumina refractory bricks, phosphate refractory bricks, magnesium-aluminium refractory bricks and so on.
Characteristics of refractory bricks
1 High-temperature performance: refractory bricks can remain stable in high-temperature environments, will not soften, deform or melt, can withstand high temperatures of up to 1700 ºC or more.
2 chemical corrosion resistance: refractory bricks can remain stable under the corrosion of acid, alkali, salt and other chemical media, without chemical reaction and destruction.
3 Abrasion-resistant performance: refractory bricks have high surface hardness and are not easy to wear and tear off.
4Good thermal conductivity: refractory bricks have good thermal conductivity, which can ensure uniform temperature in the furnace.
Application of refractory bricks
Refractory bricks are widely used in the construction and maintenance of kilns, chimneys, furnaces, furnaces, heating furnaces, heat treatment equipment, glass kilns and other industrial equipment in metallurgy, chemical industry, building materials, electric power, glass, ceramics and other industries.

Refractory brick is the core material of high temperature industrial kiln lining, in the construction of masonry, pay special attention to the technical requirements of construction, in the masonry of industrial furnace, should be based on the masonry design, through the test to determine the consistency of the slurry and the amount of liquid to add, and at the same time to check the slurry masonry performance (bonding time) to meet the masonry requirements. The bonding time of the mud is the material of the refractory products, the size of the external dimensions of the size of the appropriate 1 ~ 1.5min. different refractory brick masonry, should choose different refractory mud masonry.
