Product description
Â
High temp bricks alumina brick is a kind of middle grade Fire brick among the stereotyped products of refractory materials. It belongs to neutral refractory materials and is used in the lining of industrial kilns.
The quality of high temp bricks alumina bricks is distinguished by different aluminum content and body density, and the fire resistance of high alumina bricks reaches 1790 ℃. It is also possible to add different ingredients of raw materials to produce different materials and composite refractory bricks.

Â
Application:
Â
The use of high aluminum bricks is mainly used for wall ironmaking blast furnace, hot blast furnace, heating furnace top, blast furnace, reverberatory furnace, mechanical lining. In addition, high-aluminum bricks are also commonly used in style furnace heat storage grid bricks, plug heads for pouring management systems, and water position bricks. However, the price of high aluminum bricks is higher than that of clay bricks, so there is no need to apply high aluminum bricks if clay bricks can meet the requirements locally.
