High alumina anchor bricks are formed and calcined from bauxite or other raw materials with a high content of alumina. Its feature excellent high temperature mechanics and chemical corrosion resistance to acid and alkali basic solution.
Anchor bricks are a special kind of high alumina bricks which are used to anchor the refractory lining in the furnace. They are used to hold the refractory lining in place and to prevent the lining from shifting or moving during operation. They have unique shapes and sizes to fit the need of the furnace design and have a high mechanical strength.
High refractoriness: can withstand temperatures up to 1750 °C
Excellent thermal shock resistance: can withstand rapid temperature changes without cracking or breaking
Good chemical stability: resistant to attack from most acids and alkalis
High strength: strong enough to withstand heavy loads and wear and tear
Good insulation properties: help to maintain consistent temperatures in high-temperature environments
High thermal conductivity: enhance heat transfer efficiency in the furnace

It is mainly used for the lining blast furnace, hot blast furnaces, electric furnace roofs, reverberatory furnaces and rotary kilns.
Used in the lining of furnaces and kilns in various industries such as steel, glass, cement, and petrochemical.
Also used in the manufacturing of ceramics, non-ferrous metals, and other refractory materials.
Can be used in the construction of high-temperature equipment such as heat exchangers, boilers, and incinerators.
It finds its application in the field of nuclear power plants, aerospace, and defense as well.
It is also used in the glass industry for the production of flat glass and container glass, as well as in the cement and lime industry for the calcination process.
It is also used in the petrochemical industry as a refractory lining in cracking furnaces and reformers.
