Light Yellow Appearance High Alumina Refractory Bricks For Metallurgy

 

Description

 

We bring forth high quality High Alumina Bricks, which is manufactured to meet the requirements of neutral refractoriness where safe working temperature is more than 1300 degree centigrade. We offer High Alumina Bricks in different specifications as per customer requirements.

 

Slag resistance
High Al2O3 has high Al2O3 content, close to neutral refractory material, and can resist the erosion of acid slag and alkali slag. Because it contains SiO2, the resistance to alkali slag is less than acid resistance.

 

Load softening temperature

Since the high aluminum has a high Al2O3 content, a low impurity content, and a low formation of the molten glass body, the fire-resistant softening temperature is higher than that of the refractory clay brick. However, since the mullite crystal has not yet formed a network structure, the load softening temperature is lower than the load softening temperature of the silica brick.

 

Refractoriness
More refractory than refractory clay bricks and semi-silica bricks, up to 1750-1790C, belonging to high-grade refractory materials.

 

Features:

 

Mechanical strength

Excellent load-bearing properties

High temperature

Excellent resistance to spalling

Resistant to corrosion

 

Application:
 

By using the high alumina refractory bricks widely in insulating layers of various thermal equipments for example blast furnace, hot blast furnace, coke oven and linings where no high temperatures melt corrosion occurs.
