钢纤维是指以切断细钢丝法、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40～80的纤维。
Steel fiber is a kind of fiber whose diameter ratio (the ratio of fiber length to its diameter) is 40-80 by cutting fine steel wire, shearing cold-rolled strip, milling ingot or rapid condensation of molten steel.
不同的制取方式产出的钢纤维性能也不一样。虽然钢纤维问世不久，但应用已经越来越广泛，种类也越来越多。

The properties of steel fibers produced by different methods are also different. Although the steel fibers biaozhizh.37ix.com.cnshusongdaix.37ix.com.cnshusongdain.37ix.com.cnshusongdaip.37ix.com.cnzhongzhi.3
