Steel fiber castable is made of super grade bauxite clinker as aggregate, high quality bauxite clinker and corundum powder as matrix, ultrafine powder and other composite materials as binder and additive, plus stainless steel heat-resistant fiber. At the same time, with the addition of steel fiber, the overall strength of the furnace wall after pouring has been greatly enhanced.
Steel Fiber Castable Advantage:
- High strength;
- Good toughness;
- Good thermal shock stability;
- Excellent anti-spalling performance;
- Strong wear resistance;
- Used for the part where the change of temperature ladder can easily lead to the damage of furnace wall.
