Product Description

Customized Size Low Creep High Alumina Refractory Brick for Glass Melting Furnace
The Description:
Low creep high aluminum bricks and high aluminum bricks are close to neutral refractory materials, can resist acid and alkaline erosion, but the ability to resist alkali is weaker than the ability to resist acid. Aluminum content in 48%-80% are called high aluminum bricks, and low creep high aluminum bricks than high aluminum bricks creep rate is low, long service cycle. The reason is that the three stones are added to the low creep high aluminum brick, and the phase transition of the three stones at high temperature changes the internal structure of the high aluminum brick, and the complex phase change and micro-crack toughening are also changed, thus improving the thermal shock resistance and reducing the creep rate, which is also called low creep high aluminum brick.

4.High temperature compressive strength.

5.High temperature volume stability, good wear resistance.

6. Good erosion resistance.
3)Application:

1. Steel smelting

 

Low creep high alumina bricks are widely used in hot blast furnace, converter, electric arc furnace, intermediate tank, ladle and baking furnace in iron and steel smelting, ensuring the long-term stable operation of the equipment.

 

2, Aluminum silicate fiber kiln

 

Low creep high aluminum brick can also be used in aluminum silicate fiber kiln inner wall and top insulation layer, has excellent thermal shock resistance and chemical stability, can effectively protect the equipment from high temperature, pollution gas erosion.

3, Alumina production

 

Low creep high alumina brick is also widely used in alumina production process of high temperature reactor, heating furnace and sintering kiln and other equipment, its high temperature stability and corrosion resistance to ensure the long-term safe operation of equipment.

 

4, Glass ceramic manufacturing

 

Low creep high aluminum bricks can also be used in industrial kilns such as glass kilns and glass steel furnaces, with excellent erosion resistance and high temperature performance, which can ensure product quality and production efficiency.
