Development of rotary shear equipment for preparing short metal fibers

In order to obtain high strength short metal fibers efficiently, a new method for preparing short metal fibers by rotating shear metal rope into short length is put forward. Firstly, the principle of rotary shearing is expounded, and the design parameters of the equipment are calculated. Then, rotary shear equipment for preparing short metal fibers has been designed and manufactured. Finally, the short stainless steel fibers with good properties are prepared efficiently by shearing the stainless steel rope with this rotary shear equipment. The results show that it is feasible to produce high quality and high strength metal fiber with new rotary shear method.
