Application Of Steel Fiber Castable Advantages

The steel fiber castable advantages is the heat resistant steel fiber added by refractory aggregate, binder, admixture composed of castable refractory. It is a kind of wear-resisting material which is widely used in circulating fluidized bed boiler.

Steel fiber castable advantages, a wide range of applications, high quality products, simple and fast operation, simple construction process. Let’s take a look at the properties of this series of refractory castable.

Steel fiber castable advantages

1. Good air tightness, good insulation effect, long service life. Under high temperature use, furnace lining does not produce directional shrinkage, no cracks, furnace lining integrity is good.

2. The construction technology is simple, the speed is fast, the material consumption is small.

3. It has good mechanical properties, a certain strength, a certain bearing capacity, strong resistance to airflow erosion. The burning nozzle brick made of steel fiber castable can be used for a long time under the condition of temperature ≤1200°C.

4. It has good adaptability to the atmosphere in the furnace and can be used in various fuel furnaces. In reducing atmosphere for a long time use furnace lining stability, enhance toughness, improve stress and strain resistance, improve mechanical impact.

5. Improve thermal shock resistance, crack resistance and spalling resistance.

6. Restrain linear shrinkage after curing, drying and heat treatment.

Steel fiber castable is made of super grade bauxite clinker as aggregate, high quality bauxite clinker and corundum fine powder as matrix, ultramicron powder and a variety of composite materials as binder and additive, and stainless steel heat-resistant fiber. This series of refractory castable has the wear resistance at high temperature. In addition, a certain amount of heat-resistant stainless steel fiber is added in the ingredients to prevent the swelling and difference between the aggregate and the matrix in the material in the high temperature state, and the stress caused by the change of temperature gradient when the furnace is started and stopped, which leads to the destroy of the furnace wall. In CFB boiler, often used for furnace outlet and side wall, top, straight section of cyclone separator, cyclone separator top, return feeder and other parts.
