HyFIBER Precast Refractory Shapes Offer Superior Performance
TFL offers specialized precast refractory shapes made with Plibrico’s HyFIBER technology. HyFIBER utilizes a high quantity of stainless steel reinforcing fibers, infiltrated with a unique low-cement castable slurry in the mold. The resulting shapes exhibit extremely high toughness and impact resistance, as well as excellent resistance to thermal shock.
HyFIBER shapes provide the thermal protection of refractory in high-temperature applications, along with the mechanical properties approaching those found in steel or cast iron parts. Shapes can be custom-designed for any application. Typical HyFIBER shape applications include areas where high impact and mechanical loads are prevalent, including:
- Furnace Door Sills, Jambs and Lintels
- Damper Blades
- Curb Shapes
- Impact Pads
- Skimming Blades and Stirring Fixtures
- Rotary Kiln Nose Rings
- Replacement for Water-Cooled Doors and Structures
The Plibrico HyFIBER Slurry
Shapes can be manufactured using a variety of stainless steel fiber alloys. The Plibrico HyFIBER slurry is designed to minimize water demand and increase density. Resulting shape densities can be as much as 18% higher than other similar products on the market. HyFIBER shapes produced with type 304 alloy stainless steel fiber will have a density of between 195 and 210 pounds per cubic foot.
The image above shows the typical distribution of needle fibers within the HyFIBER slurry as the shape is being cast, resulting in unparalleled strength and impact resistance in the final shape.
