Special Andalusite Flue Refractory Brick for Anode Baking Furnace
The Description:
Anode baking furnace is one of the key equipment in the production of aluminum prebaked anode. Its general design life is 8 years, but at present, many baking furnaces are used for less than 8 years, that is, due to the poor quality of low-creep low-creep clay bricks, resulting in the sinking and fracture of baking cross wall bricks and fire channel wall bricks seriously affect the service life of baking furnaces. The key to overcome the service life of baking furnace is to improve the creep resistance, offset the line shrinkage, improve the high temperature performance and improve the strength of baking furnace clay brick.

Andalusite firebrick has the following characteristics:
1. Good fire resistance: its main component is andalusite, which has good high temperature resistance and can withstand high temperatures of up to 1700ºC.
2. Strong compression resistance: firebrick in the production and use process will be subjected to greater pressure, andalusite firebrick has a high compressive strength, can withstand greater pressure and is not easy to break.
3. Good wear resistance: easy to wear in the process of mixing, conveying, dumping, etc. Andalusite firebrick has excellent wear resistance and can extend the service life.
4. Good corrosion resistance: vulnerable to acid or alkaline corrosion under high temperature environment, andalusite firebrick has good corrosion resistance.
Andalusite refractory bricks are widely used in the following industries:
1. Steel smelting: used in blast furnaces, blast furnaces and other industrial furnaces as lining materials.
2. Refining chemical industry: used in furnaces and pipelines and other equipment as lining materials.
3. Cement manufacturing: used in rotary kilns and pulverized coal furnace tubes and other equipment as lining materials.
