钢纤维问世的时间不长，但应用领域越来越广泛，与此相应，钢纤维的品种也再不断增多。
1.按外形划分（图1）有：平直形钢纤维（a）、压棱形钢纤维（b)、波形钢纤维（c）、弯钩形钢纤维（d\e）、大头形钢纤维（f）、双尖形钢纤维（g）、集束钢纤维（h）等等。
2.按截面形状划分（图2）有：圆形（a）、矩形（b）、槽型（c）、不规则性（d）
3.按生产工艺划分有：切断钢纤维（用细钢丝切断）；剪切钢纤维（用薄钢板、带钢剪切）；
铣削型钢纤维（用厚钢板或钢锭切削）；熔抽钢纤维（用熔融钢水抽制）。有前途的是溶抽钢纤维，价格。
Steel fiber has not been out for a long time, but its application field is more and more extensive. Accordingly, the variety of steel fiber is also increasing.
1. According to the shape (Figure 1), there are: straight steel fiber (a), pressed prismatic steel fiber (b), corrugated steel fiber (c), hook shaped steel fiber (D \ E), large head shaped steel fiber (f), double pointed steel fiber (g), bundled steel fiber (H), etc.
2. Divided by section shape (Fig. 2): Circular (a), rectangular (b), groove (c), irregular (d)
3. According to the production process, it can be divided into: cutting off steel fiber (cutting with fine steel wire); cutting steel fiber (cutting with sheet steel and strip steel);
Milling section steel fiber (cutting with thick steel plate or ingot); melting drawing steel fiber (drawing with molten steel). The most promising is the steel fiber with the lowest price.

钢纤维简介编辑
以切断细钢丝法、冷轧带钢剪切、钢锭铣削或钢水快速冷凝法制成长径比（纤维长度与其直径的比值，当纤维截面为非圆形时，采用换算等效截面圆面积的直径）为30～100的纤维。因制取方法的不同钢纤维的性能有很大不同，如冷拔钢丝拉伸强度为380-3000MPa、冷轧带钢剪切法拉伸强度为600-900MPa、钢锭铣削法为700MPa；钢水冷凝法虽为380MPa，但是适合生产耐热纤维。
为增强砂浆或混凝土而加入的、长度和直径在一定范围内的细钢丝。常用截面为圆形的长直钢纤维，其长度为10～60毫米，直径为0.2～0.6毫米，长径比为30～100。为增加纤维和砂浆或混凝土的界面粘结，可选用各种异形的钢纤维，其截面有矩形、锯齿形、弯月形的；截面尺寸沿长度而交替变化的；波形的；圆圈状的；端部放大的或带弯钩的等。当使用截面非圆
形的钢纤维时，可按下式计算其当量直径（de)
ntroduction to steel fiber
The ratio of fiber length to fiber diameter (the ratio of fiber length to fiber diameter, when the fiber section is non-circular, the diameter of equivalent section circle area is converted) is 30-100 fibers by cutting fine steel wire, cold rolling strip shearing, Ingot Milling or rapid condensation of molten steel. The properties of different steel fibers are quite different due to different preparation methods, for example, the tensile strength of cold drawn steel wire is 380-3000mpa, the tensile strength of cold rolled steel strip shear method is 600-900mpa, and the tensile strength of ingot milling method is 700MPa; although the steel condensation method is 380MPa, it is suitable for producing heat-resistant fibers.
A fine steel wire of a certain length and diameter added to strengthen mortar or concrete. The common section is round long straight steel fiber with a length of 10-60mm and a diameter of Zero point two ~ Zero point six Mm, the ratio of length to diameter is 30-100. In order to increase the interface bonding between fiber and mortar or concrete, various shaped steel fibers can be selected, with rectangular, zigzag and crescent sections; cross section size alternates along the length; wave shape; circle shape; end enlarged or with hook, etc. When using non-circular section
The equivalent diameter (DE) of steel fiber can be calculated according to the following formula
改善办法编辑
⒈改善基体对钢纤维的粘结性能；即改善混凝土基体，如采用更高强度混凝土。
⒉增加纤维的粘结长度；即增加长径比，公式中lf/df。
按材质划分有：
普碳钢纤维（抗拉强度一般在300~2500MPa）；
不锈钢纤维（按材质有304,310,330,430,446等）；
其他金属纤维（铝纤维、铜纤维、钛纤维以及合金纤维）。5.按表面涂覆状态划分有：
无涂覆层，表面涂，镀锌等。工业上大量使用的是无涂覆层的普通钢纤维。
