Anti-Crust Refractory Castable

SiC Anti-Crust Refractory Castable is mainly made of silicon carbide, also called the SiC refractory castable. Adding water reducing agent and ultrafine powder, and using pure calcium aluminate cement as the binding agent can greatly reduce the number of crusting. Silicon carbide castable is suitable for large and medium-sized dry cement kiln preheater, such as feeding slope, rising flue, decomposition furnace cone and other easy crusting parts.

Silicon carbide is a synthetic raw material and is currently used more and more widely in the refractory industry. It is also the main raw material for SiC refractory castable. Due to its unique properties, silicon carbide has very little adhesion to cement raw materials. Therefore, the silicon carbide castable cement raw material is generally difficult to adhere to the surface of the SiC Anti-Crust Refractory Castable, thereby greatly reducing the agglomeration of the cement raw material at the kiln tailing slope. At the same time, it has avoided the situation that the output of the cement production line has dropped and the kiln has been shut down to clean up the ring.

Application of Snti-Skin Refractory Castable

Since the Anti-Crust Refractory Castable is doped with a large amount of silicon carbide, a furnace-lining refractory castable is used. The silicon carbide in the material is oxidized on the surface under high temperature to form a glaze protective film. When this layer of protective film on the surface is worn away by the continuous friction and erosion of the kiln material, the exposed silicon carbide continues to oxidize, and the glazed protective layer is continuously formed in this way, so silicon carbide castable always has the effect of anti-crusting.
