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.

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. 

 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. SUNSHINE®'s low cost but high  performance melt extract steel fibers provide the quickest payback. Our quality  product costs substantially less because we produce our molten steel and spun fiber on-line in one fully integrated manufacturing plant. We are able to keep fiber  manufacturing costs to a minimum, which is reflected in the very competitive prices.

SUNSHINE® has developed 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.

2. Cold Draw Stainless Steel Fiber

 

 

 

The use of  Stainless Steel Fibers in the reinforcement of refractory materials  provides substantial increase in refractory life and therefore a considerable reduction in maintenance costs. Stainless fibers significantly increase the tensile strength of the refractory in its critical period and greatly increase its energy absorption capability.  Though discontinuous, fibers act as a crack arrestor and form a mechanical bond  after cracks may occur. Stainless steel fibers greatly improve the flexural strength of  the castable. This added increase in ductility contributes greatly to thermal shock and spall resistance.

Stainless fibers cannot perform above their melting temperatures. The critical factor  therefore becomes the maximum temperature the fiber will resist oxidation. Were there are thermal gradients, if 70% of the refractory is below the critical temperature, the  fibers will perform very well. Where frequent cycling between high and low  temperatures occur, fibers will greatly improve refractory life.

The addition of 2% by weight to the refractory materials is suggested. Stainless fibers can also be used to good advantage in refractory gunning applications.  stainless  steel fibers are manufactured to a nominal size of .0.5x19MMor 25MM.

3. Cold Draw Carbon Steel Fiber 

low carbon steel fiber is used as a replacement for traditional reinforcement in various concrete applications such as: slab-on-ground, precast and shotcrete. With SUNSHINE® carbon steel fibers you can limit  micro-cracking, expect excellent concrete strength and lower costs.

Carbon steel fibers have been used successfully over the last 30 years. Normal  reinforcing such as rebar tend to only reinforce concrete in tension. The addition of  steel fibers instead of rebar or wire mesh will create a concrete with much more  plastic and ductile properties. By adding Steel Fibers you create a 3-Dimensional matrix similar to that of the aggregate throughout the mix. When  reinforced in all directions you end up with a superior concrete design. Pads will  bend instead of crack. The addition of 1" long steel fibers will increase flexural and  bending strength by 1.5 to 3 times that of standard reinforced concrete.  Steel fibers  reinforce in three dimensions throughout the entire matrix. They restrain micro-cracking by acting as tiny reinforcing bars. The earlier a crack is intercepted and its  growth inhibited the less chance it will develop into a visual crack or problem.

The  advantages that steel-fibers offer. They include but are not limited to:

  • INCREASED FLEXURAL STRENGTH
  • FATIGUE RESISTANCE
  • IMPACT RESISTANCE
  • SHRINKAGE
  • ABRASION RESISTANCE
  • PERMIABILITY
  • SUPERIOR POST CRACK STRENTH
  • MILITARY GRADE BLAST RESISTANCE
  • PUMPABLE
  • AS CLOSE TO CRACK-PROOF AS YOU CAN GET

4.  Slit Sheet Steel Fiber 

 

 

 

 

To make slit steel fiber takes shearing cold-rolled steel sheets. Before cutting, using special slitting machines make the          cold-rolled steel sheets roll up; and also, make the width of cold-rolled steel sheets to be the same as the length of the steel fiber, and then put into  rotary tool or normal punch to cut off. Rotary tool axis and sheets are perpendicular  in direction. Raw materials general use of the annealing of cold rolled steel, in order  to improve the intensity, also can use other rolled steel sheets. Because of the high  cost of the cold rolled steel plate, we often use leftover material as a raw material to  reduce costs. Products are with high tensile strength , it can be easily dispersed, and can be easily integrated with the concrete. It is a product with excellent quality and reasonable price.

Stainless Steel Fibers

What are Stainless Steel Fibers?

Steel fibers (chopped or melt extract) are used to reinforce castable, ramming mixes, and concrete to assist in abrasion resistance and added strengths at lower temperatures. Producing stainless steel fiber that meets international standards is imperative. To boost strength under tension, stainless steel fibers are commonly employed in refractories and reinforced concrete.

What Effects do Stainless Steel Fibers Have?

These fibers are available in a variety of forms and cut lengths for client convenience. Steel fiber has been put through rigorous testing to ensure that it meets the highest quality standards to make sure it brings the following effects:

  • Strength will improve
  • Tensile strain capacity is high
  • Improved material adhesion
  • Thermal compatibility is excellent

Advantages to Stainless Steel Fibers

Steel fiber is often utilized to reinforce high-temperature concretes in the refractory industry. It is known to maintain refractory strength over a wide range of temperatures. Steel fiber technology in refractory applications provides a broader range of benefits, including outstanding abrasion resistance, exceptional spalling resistance, remarkable fracture toughness, and superior resistance to mechanical and thermal shock.

Steel fiber technology has a number of advantages in refractory applications, including good abrasion resistance, great resistance to spalling, remarkable fracture toughness, superior resistance to mechanical and thermal shock, and constant alloying properties.
