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 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.
