Product Description

HIGH ALUMINA BRICK

Product Description

Description:

High alumina bricks are produced with selected bauxite chamotte by advanced process and strict quality control. The main mineral components are corundum and mullite phases. It(High Alumina Brick,Alumina Brick,Refractory Alumina) features excellent high temperature mechanics and chemical corrosion resistance.                                                                                                
 
Type: 
According to Al2O3 content, the bricks are separated in to types as following :FMLZ-45 FMLZ-50 FMLZ-55 FMLZ-60 FMLZ-65 FMLZ-70 FMLZ-75 FMLZ-80 FMLZ-85
 
Application:
High alumina bricks are widely used in the basic zone of metallurgical furnaces, nonferrous furnaces , regenerator of glass furnaces, power plant circulating fluidized bed boiler etc.
