Fine Thermal Shock Stability Alumina Refractory Bricks High Refractoriness Under Load
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.
Features
Low coefficient of linear expansion
Low thermal conductivity
Strong resistance to the acid slag erosion
Excellent thermal shock resistance
High Refractoriness under load
Low high-temperature creep rate
