Brief introduction of steel fiber

Steel fiber refers to the short fiber with steel, the steel wire cut, and in accordance with the provisions of the style to be pressed into a curved hook at both ends, with a certain intensity. Steel fiber is mainly used in the manufacture of steel fiber concrete, and used in the tunnel, industrial flooring and other fields.
Classification of steel fiber
The advent of steel fiber is not long, but more and more widely used in the field, with this corresponding, steel fiber varieties are also increasing.
According to the shape of the division:
Flat steel fiber, pressure prismatic steel fiber, waveform steel fiber, bending hook shaped steel fiber, big head shaped steel fiber, double pointed steel fiber, cluster of steel fiber and so on.
2 according to the section shape:
Round, rectangular, groove type, irregular
3 according to the production process:
Cut off the steel fiber (cut off with a fine steel wire);
Shear steel fiber (with a thin steel sheet, strip shear);
Milling steel fiber (steel or steel ingot cutting);
Molten steel fiber (molten steel pumping). The most promising is the dissolution of steel fiber, the lowest price
4 according to the material is divided into:
Plain carbon fiber (tensile strength is generally in 300~2500MPa);
Stainless steel fiber (according to the material 304310330430446, etc.);
Other metal fibers (aluminum, copper, titanium and alloy).
According to the state of surface coating:
No coating, surface coating of epoxy resin, zinc, etc.. The industrial use of a large number of ordinary steel fiber without coating.
According to the classification of construction technology:
Injection and casting.
But according to size classification:
Ordinary steel fiber (diameter d>0.08mm);
Ultra-fine steel fiber (diameter d = 0.08mm);
Superfine steel fiber is mainly used to strengthen the friction material of plastic and asbestos.
