Product Description
Product Description of Rongsheng High Quality Refractory Brick High Alumin Checker Brick 48%-80% Al2O3 With 7/9/31/37/48/65 Holes
High Alumina Checker Refractory Brick is a type of refractory brick that is made with a high alumina content, typically over 48%. This gives the brick excellent high-temperature resistance, thermal shock stability, and low thermal conductivity.
High Alumina Checker Refractory Bricks are commonly used in hot blast stoves, which are used to preheat air before it is introduced into a furnace. The bricks are arranged in a checkerboard pattern, which allows for efficient heat transfer between the air and the bricks. The bricks are also able to withstand the high temperatures and harsh conditions of the hot blast stove.
Features of High Alumina Checker Refractory Brick
1. High refractoriness.
2. Good spalling resistance and wear resistance.
3. Good corrosion resistance.
4. Good thermal shock resistance.
5. High mechanical strength.
6. High-temperature creep rate is low.
Application of High Alumina Checker Refractory Brick
In addition to hot blast stoves, High Alumina Checker Refractory Bricks are also used in a variety of other industrial applications, including:
Cement kilns
Glass tank furnaces
Pot furnaces
Anode baking furnaces
Petrochemical plants
Fertilizer plants
Boilers
Coke ovens
Hot metal ladles
