Product Description

 

Hot Sale Refractories Industrial Ceramics Machine Pressed Refractory High Alumina bubble Bricks

Introduction:
High alumina brick refers to refractory products with Al2O3 content higher than 48%.It is made of bauxite or other raw materials of high alumina content .The refractoriness of high alumina brick can be more than  1770ºC .
According to the content of Al2O3, high alumina bricks are usually divided into three grades: Grade I──Al2O3 content>75%; Grade II──Al2O3 content is 60~75%; Grade III──Al2O3 content is 48~60%.
 
Features:
1.Low creep.
2.Good slag resistance.
3.Strong thermal shock stability.
4.Good erosion resistance.
 
Application:
High alumina bricks are mainly used for lining blast furnaces, hot blast furnace, electric furnace roofs, blast furnaces, reverberatory furnaces, and rotary kilns.
