Stainless steel Melt Extract steel fiber reinforcement offers substantially improved refractories, durability and performance. Melt Extract steel fiber reinforce refractory against cracking to extend and enhance refractory lifetimes. Our Melt Extract steel fiber 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. Melt Extract steel fiber are mainly used for reinforcement of refractory products in various industries, such as Petrochemical, steel, chemical, power station, cement and rock industries. Our grades of Melt Extract steel fiber are mentioned below.

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. Melt Extract stainless fibers are fully annealed and therefore are more pliable and ductile. This is of particular benefit during the mixing cycle and when the refractory composite is installed. These pliable fibers are not only more user-friendly than the stiff “needle-like” cut fibers, but also have better flow characteristics. Dispersion is further aided by the optimum Aspect Ratio design guaranteeing rapid fiber separation during the mixing phase.

The normal diameter of stainless steel fiber is 0.3mm~0.7mm with a length of 20~60mm. To avoid agglomeration during stirring, the ratio of the length to the diameter should 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.

Cost savings are the main reason for adding stainless steel fibers. In all areas of high thermal and mechanical shock, fibers will at least double refractory life. Fiber costs up to 50% lower than comparable products. Melt extract steel fiber which features thermal shock resistance, steep thermal gradients resistance and mechanical shock resistance, minimizing damage and decaying 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.
