High Refractoriness Alumina Refractory Bricks Calcined Bauxite Raw Materials

 

Description

 

The first-grade high-alumina brick (the aluminum content is not less than 75% refractory brick) is formed by pressing and calcining a high-quality raw material such as high-quality bauxite and alumina. The high-aluminum brick has a refractoriness of over 1790 °C. The load softening temperature is above 1510 °C, the thermal shock stability is good, and the slag resistance is good. It is mainly used for ladle furnace, masonry blast furnace (furnace, belly), hot blast stove (upper), electric furnace cover (top) Blast furnace, reverberatory furnace, rotary kiln lining etc...

 

Our alumina bricks have excellent mechanical strength, good resistance to thermal spalling, and are highly resistant to chemical attack by vilatile alkaies and some slag. We manufacture and design alumina bricks to meet the requirements of a great variety of service conditions thorough quality control.

 

Application

 

High-aluminum bricks are mainly used for masonry blast furnaces, hot blast stoves, electric furnace tops, blast furnaces, reverberatory furnaces, and rotary kiln linings. In addition, high-aluminum bricks are also widely used as open-hearth regenerative lattice bricks, plugs for gating systems, and shingles.

 

Features

 

1. High refractoriness.
2. Good spalling resistance and wear resistance.
3. Good corrosion resistance.
4. Good thermal shock resistance.
