Description of Alumina Refractory Bricks
The Alumina Refractory Bricks 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.
