Steel Fiber Refractory Castable Introduction: Steel fiber high-strength wear-resistant castable is a kind of super refractory products which is made of high level of bauxite as aggregate, high level high quality bauxite clinker and alumina powder as the matrix, pure calcium aluminate cement as binder, ultrafine powder as additive, add the prescribed number of heat resistant stainless steel fiber. Because of its high strength and integrity, it has been widely used in electric power industry. In the fluidized bed boiler is mainly used in the separator straight segment, inlet and outlet of the separator, cone separator, etc. Steel Fiber Refractory Castable Features and advantages:  1. High refractoriness, High refractoriness under load. 2. High density, low porosity. 3. Good slag resistance and corrosion resistance. 4. High strength and wear resistance. 5. Good resistance to flake performance. 6. Good thermal shock stability. 7. Scouring resistance 8. Good hot strength.
