Introduction of Alumina Refractory Bricks
The bricks we offer are widely applauded for their dimensional stability, compressive strength and durability. Moreover,
Super Heat Duty and High Alumina Fire Bricks are the products made from different fractions of refractory grog, fire clays and calcined bauxite of high purity. The different fractions of these raw materials are mixed in counter current mixers and plugged for obtaining homogeneous mixture. The mixture obtained hence, is then pressed in high capacity presses to give the desired shape and size. These pressed shapes are fired in high temperature tunnel kiln at 1300°C and above.
Advantages of Alumina Refractory Bricks:
1. High resistance to thermal shock, abrasion, chemical attack to provide long service life;
2. High dense structure;
3. Low permanent linear change on reheating;
4. Easy operation and installation;
