These characteristics of high alumina refractory brick determine its price
May 09, 2022
High alumina refractory brick, that is, an aluminum silicate refractory material with an alumina content of more than 48%. Below, I will teach you how to measure the price of high alumina bricks based on the principle of "value = price".
Influence of aluminum content on the price of high alumina refractory brick
Its high-temperature creeps property was also measured to reflect its high-temperature structural strength. The test results show that the softening temperature under load increases with the increase of Al2O3 content.
The alumina content of alumina refractory brick is more than 48% and belongs to neutral refractory bricks. It is formed and calcined from bauxite or other raw materials with high alumina content. High thermal stability, the temperature of refractory brick manufacturers is above 1770 ℃. Higher, such as I, II, and other high-alumina bricks are generally 1500 ~ 1600 ℃ when fired in a tunnel kiln.
