SUNSHINE melt extract steel fiber of our company impart increased thermal shock resistance, steep thermal gradients resistance and mechanical shock resistance, minimizing damage and delaying failure caused by cracking. By increasing refractory lifetimes steel fiber refractory reinforcement offers the end user a reduction in downtime and substantial savings in materials and labor costs.
Production:
Melt Extract stainless steel fibers are spun directly from the melt using the company's advanced Melt Extraction (ME) and Melt Overflow (MO) processes. Rapid cooling of the fiber during manufacture (equivalent to 50,000 per second) "freezes" the metallurgical structure, capturing it in an optimum state to resist high temperature corrosion - a state which is impossible for conventionally cast steel to match.
The processing maximizes the effective distribution of the primary nickel and/or chromium alloying elements throughout the fiber while simultaneously minimizing grain size. When coupled with Sunshine’s skill of blending non-standard levels of performance-enhancing key trace elements to the melt, a unique range of dedicated refractory fiber alloys have been produced which provide outstanding oxidation resistance and unmatched performance at elevated temperature.
Steel Fiber Size:
The normal diameter of stainless steel fiber is 0.3mm~0.7mm with a length of 20~60mm. To avoid agglomeration during sirring, the ratio of the length to the diameter shoud be controlled in the range of 30~80. It should be noted that if a process of jet spray is applied, stainless steel fiber of a shorter length <25mm should be selected, otherwise the spray jet shall be blocked.For special applications other lengths and diameters are also available.
Steel Fiber Grade:
The grades of steel fiber should be suitably selected based on the temperature and atmosphere.
Steel Fiber Packing:
Steel fiber should be first spread evenly into the refractory materials, and mixed in a dry state and then in a wet state. To avoid the difficulty of installation due to agglomeration, a packing of an orderly array in paper boxes should be first considered.
