Product Description

Functions of Melt-Extracted Fibers
Melt-extracted fibers, produced through rapid cooling and solidification of molten metal alloys, exhibit exceptional mechanical strength, thermal resistance, and corrosion durability. These ultrafine, high-purity fibers are engineered to disperse uniformly within composite matrices, enhancing structural integrity without compromising flexibility. Their high surface-area-to-volume ratio ensures optimal bonding with host materials, making them ideal for reinforcing applications. Additionally, their resistance to extreme temperatures (up to 1200°C) and chemical degradation enables reliable performance in harsh environments, from industrial furnaces to corrosive settings.

Application in Concrete Reinforcement
In concrete reinforcement, melt-extracted stainless steel fibers significantly improve tensile strength, crack resistance, and impact durability. When mixed into concrete matrices, they form a 3D reinforcement network that mitigates shrinkage cracks and delays structural failure under load. Compared to traditional steel bars or synthetic fibers, they offer superior dispersion, preventing clumping and ensuring consistent stress distribution. This makes them ideal for high-stress applications like industrial flooring, tunnel linings, and seismic-resistant structures. Their corrosion-resistant properties also extend the lifespan of concrete in humid or salt-rich environments, reducing maintenance costs and enhancing sustainability.

Main function:
Mixing moderate Xorex steel fibers into concrete, its tensile strength will be raised by 20%-50% and its flexural strength will rise by 40%-80%. In case of usual dosage of fibers, compressive impact toughness can be reinforced by 2-7 times, toughness of impact shear and tensile malleability will be strengthened obviously. Concrete mass itself is a multiphase, multicomponent, non-homogeneous granular brittle composite material. Its compression ratio is only about one-tenth. What's more, it has pretty low anti-crack ability. Incorporation of steel fibers can block emergence of crack, decrease size of fracture source, and zoom out quantity of crack source. It enables concrete to suppress the extension and propagation of cracks, as well as relieve crack stress and concentration in the process of standing force. 

Construction Proposals:
1. Dosage: The dosage of steel fiber is based on the design requirements of the actual engineering application design institute. General dosage is 30 kg/m³-80kg/m³.  
2. Mixing process of steel fiber and concrete: constructing refer to routine, don't have to adjust specially. 

Main Applications:
1. Metallurgical industry
The refining outside the furnace airbrush, dipping tubes, slag dam, bag lining cover, the triangle electric furnace, furnace cover, the molten iron trench cover, the torpedo cans, coke oven door, the heating furnace of steel rolling door, furnace roof, burn tsui, annular furnace baffle wall, hearth roll, forging steel furnace, steel tanks etc, items can be used for various refractory kiln linings.
2. The construction industry
Steel fiber mixed with mixes clay is rapid development of new composite materials in recent years, especially for the steel fiber concrete fastest development. Steel fiber with excellent tensile, bending, shear and crack resistance, impact resistance, resistance to fatigue, high toughness properties, are all items widely used in construction, road, bridge, tunnel, airport pavement, hydraulic harbor, engineering, all kinds of buildings and products etc.
3. Kiln
Sintering furnace, reduction furnace, finer, the flue, furnace burning tsui and other heat-resistant linings.
4. Petroleum chemical industry
Especially in the refining the lining of catalytic cracking units.
5. Electric power industry
Thermal power plant boiler heat resistant linings.
6. Environmental protection industry
7. Incinerator.
