Description

High Alumina Refractory Bricks Introduction
  
High alumina brick is a kind of alumina-silicate refractory material with content of alumina oxide more than 48%. It is calcined and formed by the raw material of bauxite or the material with high content of AL2O3. High thermal stability, the refractoriness is more than 1770℃. Good slag resistance, used for the liner of masonry steel-making electric stove, glass furnace and cement revolver.
 
Use Of High Alumina Refractory Bricks
 
High alumina brick is widely used in blast furnaces, Hot Blast Stove,Steel ladle lining, Reheating furnace, Cement kiln, Tunnel kiln,boiler, coke oven, carbon furnace, glass kiln , Steel smelting furnace and various kiln lining and thermotechnical equipment, etc.
