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.
Our total annual production capacity is about 100,000 tons of dense-shaped refractory product, and 100,000 tons of monolithic refractory product.
We have three tunnel kilns for silicon-aluminum dense bricks and one new plant for the monolithic refractory.
We're sure our custom-made products and professional services will bring you a stable quality supply and more profit.
