Application:
These bricks are widely used as the hot face linings on tunnel kilns and shuttle kilns.
For most high temperature kilns, the kiln car platform is built using bubble alumina bricks.
In most cases, the bricks are available in shapes such as rectangular, arch, end arch, key and wedge.
Bricks with tongue and grooves are also available on request.
Packing details:
On wooden pallets with plastic cover or according to requiremnts of customers.
