This series of high temperature kiln refractory high alumina bricks
use special grade aluminum bauxite clinker as the main raw
material, supplemented by special additives, high pressure forming
and high temperature firing. Refractory bricks alumina has the
characteristics of large heat storage capacity and small creep
rate.
The high alumina brick made by CH refractories with very widely
application and various size with free mold charge to meet
different kiln applications. To be professional high alumina
furnace brick manufacturer since 1984, CH refractories provides
alumina lining bricks not only can design fire furnace bricks size
according to your kiln or furnace drawing for free, but also
