Application of Alumina Fire Brick
Description of Alumina Fire Brick
The Alumina Fire 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...
