无论哪一种加工方法制造的钢纤维，在加工过程中都遇到高热和急剧冷却，相当于淬火状态。因此钢纤维的表面硬度都较高。用于混凝土补强进行搅拌时很少发生弯曲现象。如果钢纤维过硬过脆，搅拌时也易折断，影响增强效果。在熔抽法生产钢纤维时，从熔抽轮下离心喷出的钢纤维仍处于高温状态，必须用滚筒或振动输送方法分散并进行冷却。否则钢纤维聚集，热量难以散发，反而起退火作用。

The steel fibers manufactured by either method are subjected to high heat and rapid cooling during processing, which is equivalent to quenching state. Therefore, the surface hardness of steel fibers is higher. The bending phenomenon rarely occurs when concrete is stirred for reinforcing.

In the production of steel fibers by melt extraction, the steel fibers ejected centrifugally from the melt pulley are still in a high temperature state, which must be dispersed and cooled by means of drum or vibration conveying. Otherwise, the steel fibers gather and the heat is difficult to dissipate. Instead, it acts as annealing.
