Melt Extract stainless steel fibers reinforce refractory against cracking to extend and enhance refractory lifetimes. The steel fibers can be added to all monolithic refractories, from insulating to ultra low cement refractory castable, ramming materials & moldable, precast shapes, gunning and shot creting mixes. Steel fiber reinforced refractories are now commonplace in a wide range of high temperature processing industries.
NR melt extract steel fibers impart increased strength and resistance to thermal cycling, steep thermal gradients and mechanical shock, minimizing damage and delaying failure caused by cracking. By increasing refractory lifetimes steel fiber refractory reinforcement (SFRR) offers the end user a reduction in downtime and substantial savings in materials and labor costs.
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.
Mainly used for reinforcement of refractory products in various industries, such as Petrochemical, steel, chemical, power station, cement and rock industries, etc.
