Function, advantage and size of high alumina brick
High alumina brick is a kind of refractory brick which is widely used in cement kiln. High alumina brick is mainly composed of alumina and high purity quartz sand and other raw materials. As a kind of high quality refractory material, many people in the industry do not know much about high alumina brick.
First, the introduction of high alumina brick
High alumina brick is a kind of high performance refractory material, its main components are alumina and high purity quartz sand and other raw materials. High alumina brick has the characteristics of high temperature corrosion resistance, insulation and good stability, and is widely used in various high temperature environments in industrial kiln, furnace, iron and steel smelting, glass kiln and other fields. The manufacturing process of high alumina brick includes raw material screening, mixing molding, drying, baking and other steps. According to different application scenarios, high alumina bricks can be divided into many varieties and specifications, such as straight, curved, cone, etc. High alumina brick has the advantages of high strength, good durability, safety and environmental protection, and is one of the indispensable important materials in the modern high temperature environment of construction and industry.
Two, the role of high aluminum brick
1, withstand high temperature thermal shock: high aluminum brick can withstand rapid heating and cooling in high temperature environment, resist high temperature thermal shock. Therefore, it is widely used in industrial kiln.
2, corrosion resistance: high aluminum brick has strong alkali resistance, acid resistance, can be used in harsh chemical environment.
3. Insulation and heat insulation: high alumina proportion of high aluminum bricks, with good insulation performance.
4, durability: high aluminum brick long life, not easy to wear or crack, service life can reach more than 10 years.
5, stability: high aluminum brick material stability, not easy to deformation or cracking, can ensure the use of stable effect.
Three, the advantage of high aluminum brick
1. Strong durability: Long service life of high aluminum brick can reach more than 10 years. It is made of high purity quartz sand and alumina and other raw materials refined, is not easy to wear or crack, maintain a long time stability.
2, strong corrosion resistance: high aluminum brick can greatly resist acid and alkali erosion, but also can withstand the harsh chemical environment. Therefore, it is widely used in metallurgy, chemical industry and other fields.
3, good high temperature thermal shock resistance: high aluminum brick has good high temperature thermal shock resistance performance, can withstand rapid temperature change under high temperature conditions. Therefore, it is suitable for all kinds of industrial kiln, furnace and other high temperature environment.
4, good insulation and heat insulation: high alumina brick proportion is high, so it has good insulation performance, can effectively save energy.
5, safety and environmental protection: high aluminum brick is harmless and non-toxic, harmless to human body and the environment, in line with safety and environmental protection requirements.
Four, high alumina brick specifications and dimensions
High alumina bricks have various specifications and sizes. Common specifications are as follows:
1, straight high aluminum brick: 230mm × 114mm × 65mm, 230mm × 114mm × 75mm, 230mm × 114mm × 50mm, 220mm × 110mm × 50mm, etc. /2, curved high aluminum brick: radian radius of 500mm, 600mm, 700mm, 800mm and other different specifications. Among them, straight high alumina bricks are suitable for refractory buildings in right-angle environment such as industrial kilns and furnaces, while curved high alumina bricks are suitable for industrial kilns, iron and steel smelting and other occasions with higher arc requirements.
3, conical high aluminum brick: suitable for precision machining and production in a small space, such as electronic components manufacturing and other fields.
In addition, high aluminum bricks can also be divided into a number of varieties according to different aluminum content, such as AL55, AL60, AL65 and other different models, each model has a different refractory temperature range and application. In short, the specifications and sizes of high alumina bricks vary from application to application, and selecting the appropriate specifications and sizes can better meet the needs of refractory materials.
The above is the function, advantage and size information of high aluminum brick organized by Zhenjin refractory. I hope it will have certain reference value for you.
