METHOD OF PRODUCTION OF STEEL FIBERS, STEEL FIBER STRIP OR A METALLIC STRIP AND STEEL FIBER

摘要

production method of steel fibers, steel fiber strip or a metallic strip and steel fiber the present invention relates to a method of production of steel fibers, preferably for use as a concrete additive, and for its supply in the production of concrete with steel fibers, characterized by the fact that to form steel fibers (2) initially a strip of sheet metal (1) is beveled either on one side or on both sides, while fiber veins are formed steel (4), which are initially still connected to each other by members (5), which subsequently convert the members (5) into mutually separable and easily separable members forming separation surfaces that are fracture-hard and of low deburring in the separation, the steel fiber strip is subjected to a separation process in which each member (5) is subjected to deformation by multiple folds around its longitudinal axis in such a way that incipient fractures are produced in the region of the mem bros (5) due to fatigue fracture, and thus the separation of the limb is produced.
