Product Description

SK38 High Quality Bauxite Raw Material High Alumina Refractory Brick for Blast Stove
The description:
High alumina brick is a new type of refractory material made of high purity alumina as the main raw material, adding an appropriate amount of precious metal catalyst, rare earth elements, boric acid and other auxiliaries. The high purity alumina content of high aluminum bricks reaches more than 90%, and there are no other impurities. Therefore, high-aluminum bricks have good fire resistance and corrosion resistance, and are widely used in the manufacture of linings and components of various high-temperature equipment.

Advantages and disadvantages of high aluminum bricks

a. High temperature resistance, corrosion resistance: high aluminum bricks have very high fire resistance and corrosion resistance, with good durability and maintainability.

b. Aging resistance and wear resistance: high aluminum bricks have stable physical and chemical properties, and are not easy to age, fracture and wear.

c. Strong shock resistance and long service life: high aluminum bricks show strong shock resistance and reliability in high temperature environment, and long service life.

Shortcoming:

a. Relatively high manufacturing cost: the production process requires high temperature, high pressure and other conditions, and the manufacturing cost is high.

b. It is susceptible to external forces such as vibration and vibration during transportation, and it needs to be transported with caution.
