Low Creep Alumina Bricks Manufacturer 1500C 1550C Alumina Refractory Brick
Low Creep High Aluminum Bricks for Hot Blast Furnace
Low Creep High Aluminum Bricks for Hot Blast Furnace/Low creep rate /Good volume stability/Good resistance to gas erosion and erosion resistance/Excellent high compressive strength
Summary:
Low Creep High Aluminum Bricks is a kind of high aluminum refractory brick, because of the characteristics of low creep rate, it is called low creep high aluminum brick, which is used in high temperature industrial kilns under long-term high temperature environment.
Product features:
- 1. Low creep rate and good volume stability at high temperature. Under the action of constant temperature and constant load, high aluminum brick with the change of time, its interior with smaller changes, stable volume under high temperature environment, not raw furnace lining off and other dangers
- 2. Good resistance to gas erosion and erosion resistance. In the high temperature environment, low creep high aluminum brick not only the volume does not change, good resistance to gas scour, long service life
- 3. High compressive strength, good wear resistance. low creep high aluminum brick can withstand large gas pressure and resist the impact of dust in the gas
Range of application:
Can be used in hot blast furnace, can also be used in other industrial kilns.According to the specific construction requirements, low creep high aluminum bricks of different sizes are made, such as lattice bricks, special-shaped bricks, anchor bricks, etc., which are mainly used in industrial kilns with long-term high temperature environment.
