The development of China's steel fiber industry also needs to improve the technical level, realize the industrialization of steel fiber, narrow the gap between the technical level the international level. Steel fiber is a kind of fiber whose diameter ratio (the ratio of fiber length to diameter, when the fiber section is non-circular, the diameter of equivalent section circle area) is 40-80, which is produced by cutting thin steel wire, shearing cold rolled strip, milling ingot rapid condensation of molten steel. Low carbon steel fiber can be used for steel fiber reinforced concrete at room temperature, while stainless steel fiber must be used for fire-resistant steel fiber reinforced concrete. Adding proper amount of steel fiber into mortar concrete can improve its tensile strength, bending strength, toughness impact strength. Steel fiber has the advantages of using its own advantages customers. It is more more clearly recognized that the advantages of daily enterprises in recruiting steel fiber in projects can only save manpower manpower, but also improve the tensile strength of buildings on the premise of saving project cost. The shear crack strength has been perfect scientific verification. It is expected that the output consumption of polypropylene fiber will maintain a certain growth in the future, which will also enhance people's confidence in the future development of steel fiber application market.
