Features and Applications of High Alumina Bricks
June 20, 2018
1.Common High Alumina Brick
Features：High alumina bricks are of high refractoriness, good resistance to chemical erosion.
Applications：High alumina bricks are widely used in metallurgy, crude oil refinery, chemical, construction and etc.
High alumina bricks for blast furnace take high quality bauxite as the main raw material, shaped with high pressure, calcined at high temperature. The main mineral composition is mullite and corundum.
Features: High alumina bricks for blast furnace have good resistance to chemical erosion.
Applications: It is widely used as the linings of blast furnace.
3.High Alumina Bricks for Steel-making Furnace
Features: The high alumina bricks for steelmaking electric furnace roof, used special grade bauxite as the raw material, shaped under high pressure and high temperature. The main mineral composition is corundum and mullite phase. The high alumina bricks are of high temperature mechanical properties and chemical resistance. In particular, non-fired products have more precise dimensions and better thermal shock stability.
4.High Alumina Bricks for Ladle
Features：The high-alumina bricks used for ladle are made of selected bauxite. The main minerals are corundum and mullite phases. The alumina bricks are of good high temperature mechanical properties and chemical resistance.
5.Low Creep High Alumina Brick for Hot Blast Furnace
The low creep series high alumina bricks for hot blast furnace are made of corundum mullite and high-quality bauxite, which are shaped and calcined on the condition of high pressure and high temperature.
Features: It has high refractoriness under load and low creep under high temperature.
Applications：It shall be the first choice for hot blast furnace.
