High Alumina Andalusite Silicon Carbide Brick ASC Bricks for Cement Rotary Kiln

Description Of ASC Brick:

Due to the different combination methods, there are differences in the process. The brief process of different combinations is:
(1)  Silicon nitride bonded silicon carbide brick: a green body formed with coarse, medium and fine silicon carbide particles and fine silicon powder, in pure N2 gas, at 1370 ℃, produces a kind of %26α-SiC as the skeleton and %26α and %26β-Si3N4. The substrate is silicon nitride bonded with silicon carbide bricks. There are still a small amount of residual silicon and SiO2N2 in the matrix in the product, and the relative content of these components varies with manufacturing plants.

(2)  Combining silicon carbide bricks: SiC, silicon powder, and carbon powder are mixed and shaped according to a certain ratio, and then fired in a reducing atmosphere at 1400°C. In most cases, buried charcoal firing is used. During the firing process, a %26β-Si3N4 bonded SiC brick with %26α-SiC as the framework and fine grain %26β-SiC as the matrix is produced. %26β-SiC is produced by the reaction of fine silicon powder and fine carbon powder during the firing process. This product also contains a small amount of residual silicon and carbon.

(3)Silicon oxynitride combined with silicon carbide brick: When this kind of brick is compounded, the proportion of fine silicon powder is less than that of silicon carbide.
