Hunan Sunshine Steel Fiber Co., Ltd. is the refractory industry's No. 1 supplier of carbon and stainless steel fiber and is dedicated to product development and customer service. Its annual production capacity is over ten thousand MT. The company is strong in its technical force. It has advanced melt extract, cold draw and slit sheet steel fiber production line. The company has the fullest types of steel fiber production mills, most numbers of advanced equipment models, and it has the best matches of the sizes among all its mills.
After ten years development, the company continuously cultivate its own innovation ablitiy, steel fiber for metallurgy, steel fiber for petrochemaical industry, steel fiber for cement , steel fiber for construction are 4 major supporting products of our company . The production of the refractory anchor and hex steel are also very famous . we have developed our own brand sunshine products.
With the professsional technology, advanced production line and test equipment and perfect quality guarantee system, our products are to be in the lead of steel industry both in chemical composition and physical properties. With international advanced management mode, we have passed the ISO 9001:2008 quality system certification successfully 
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 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.
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.
