Mixing Stainless Steel Fiber for Refractory Castables Introduction
Steel fiber castable ( high strength refractory castable ) is made from refractory aggregate, powder, binder, additive and steel fiber. The fibers generally used are in size varying between 0.1 to 0.4 mm2 in cross-section & 20-40 mm in length, the addition of 2% by weight to the refractory materials is suggested. Steel fiber reinforced castable greatly enhanced tensile strength, thermal shock resistance level, wear resistance capacity and service life. So steel fiber refractory castable is very resistant to the tendency of material falling apart during thermal cycling compared with refractory castable which exhibits very low fracture strain levels when subjected to tension or bending. Stainless steel fiber castable is widely used in the high temperature wearable parts such as kiln eye, feed opening, the wearable pier and the lining of power plant boiler.
The Advantages of Castables with Steel Fiber
- Steel fiber greatly increased tensile strength and ductility, contribute significantly to Spalling resistance.
- Thermal shock resistance, wear resistance, impact resistance.
- Greatly increase refractory castable energy absorption capacity.
- Good performance in medium and high temperature, good volume stability.
- Stainless steel fibers greatly improve the flexural strength of the castable
- Steel fibers act as a crack arrestor and form a mechanical bond after cracks may occur.
- Long service life, greatly reduce maintenance costs.
