Fire Resistant Dry Pressed High Alumina Insulation Refractory
Bricks , High Density
Description:
Combined High Alumina Refractory Bricks
Feature:
1. bricks are made from high quality bauxite
2. dry pressed
3. burned under tunnel kiln
4. accurate dimension
5. high strength
Product specification:
standard form, normal standard, shaped and special shaped
bricks.Can be used in various kilns because of its cheapness and
general tray package. Among all of the refractory materials, it is
the mostly used in the key positions.Molding method: it has down
draft kiln and tunnel kiln and the general sintering temperature is
1360-1480 degrees. It is a kind of aluminosilicate refractory
product which aluminum oxide (Al2O3) content is higher than 48%.
Applications:
1. Steel furnaces
2. Iron making furnaces
3. Glass kiln
4. Ceramic tunnel kiln
5. Cement kiln
Specifications:
