Steel Fiber Refractory Castable

It is made of dense bauxite as the main raw material, pure calcium aluminate cement as the bond, appropriately added in some silicon carbide, silica micro powder, expanding agent, and additive.

It is a kind of castable made of fireproof aggregates, binding agents, additives, and fireproof steel fiber of certain sizes (length: 20-35mm, sectional area: 0.13-0.2cm2).

Features:

1. It restrains the shrinkage of castable during maintenance, drying, and service.
2. It improves the toughness, resistance to mechanical impact, and mechanical strength.
3. Better thermal shock resistance.
4. It prevents the microcrack produced under thermal and mechanical stresses from the extension which will lead to breakage and spalling.

Application:

It is mainly used in the building material industry and parts of other industrial furnaces that require good anti-stripping performance and impact resistance, such as kidneys of cement rotary kiln, heat resistant steel chain zone of wet rotary kiln, cooling machine of cement kiln, coal-injection duct, etc.
