High Alumina Brick
High alumina bricks are made of silicate clay and high alumina powder by heating and firing. They have high fire resistance, light texture, and the normal service temperature can reach 1400 ° C. They have good corrosion resistance. Stronger than silicate bricks and therefore suitable for high temperature corrosion rings.
1. High fire resistance performance
2. Light weight and heat resistance
3. Good corrosion resistance
4. Solid structure
5. Energy saving
High Alumina Brick Description
High alumina brick is a kind of brick made of high alumina clay, which has the characteristics of high aluminum content, high temperature resistance, wear resistance and alkali resistance.
It is mainly used to build indoor and outdoor walls of industrial kilns and other industrial furnaces.
High alumina bricks also have the characteristics of environmental protection and energy saving.It is a green building material and has become an ideal material for industrial kiln decoration.
The Application Of High Alumina Brick
High alumina bricks are mainly used for heat preservation of the aluminum alloy ladle on the inner wall of the furnace. It can effectively prevent the heat from escaping, protect the heat of the ladle wall, and improve the thermal efficiency of the furnace.
High alumina bricks are widely used in waste incinerators. They can be used as heat exchange surfaces in the furnace, thereby improving the thermal efficiency of the furnace and reducing pollutant emissions. And it also can prolong the service life of the furnace.
The application of high alumina bricks in the cement rotary kiln can make the temperature in the kiln more uniform, save energy and improve efficiency. It can also reduce the temperature of the kiln and reduce the gas emissions generated during firing in the kiln.
The application of high alumina bricks in glass kilns is mainly as the lining material for sintered glass in the kiln to protect the inner wall of the kiln from corrosion by high temperature glass.
As a new type of refractory material, high alumina bricks are widely used in lime kilns due to their good oxidation resistance, and they can maintain the stability of lime kiln firing process parameters.
Due to its good fire resistance and alkali resistance, high alumina bricks can be used in the heat chamber, heat exchanger and other structures of the heating furnace to increase the temperature of the heating furnace.
