Steel fiber is a common reinforcing material that is widely used in various engineering fields.
The production process mainly includes melt pumping, drawing, shearing, milling and laser cutting. Among them, the melt pumping method and the drawing method are the two most commonly used methods. The melt pumping method is to pass the molten steel through a small hole, and the small hole is elongated during the cooling process to form a fibrous shape. The drawing method is to stretch the steel wire or steel rod through a series of molds, gradually reduce the diameter, and finally form a fibrous.
Steel fiber has many excellent performance characteristics, mainly including the following aspects:
1.High strength and toughness.
Steel fibers have high tensile strength and elastic modulus, as well as good toughness and are able to maintain integrity despite large deformations.
2.Durability and stability.
Steel fibers have good durability and stability, and can maintain their properties for a long time under various environmental conditions.
3.Excellent dispersibility.
Steel fibers are less prone to agglomeration and can be evenly dispersed in the matrix material, thereby improving the overall performance of the composite material.
4.Good processability.
Steel fiber can be compounded with various materials, with good processing performance, and can be made into products of various shapes and sizes.
The application field of steel fiber is very wide, mainly including the following aspects:
1.Highway construction.
Steel fiber reinforced concrete is used in pavement and bridge construction, which can significantly improve the wear resistance, crack resistance and impact resistance of pavement and prolong the service life of pavement. At the same time, it can also reduce road noise and reduce maintenance costs.
2.Architectural field.
In the field of construction, steel fiber reinforced concrete can be used to make structural parts such as wall panels, floor slabs and columns to improve the strength and seismic performance of the structure. In addition, steel fibers can also be used to make structural supports for glass curtain walls.
