Production technology of cold drawn steel fiber
The cold-drawn steel wire with a diameter of 0.4 ~ 0.8mm is cut into short fibers with a cutter, punch or rotation according to the specified length. The tensile strength of steel fiber made of cold-drawn steel wire can reach 1000-2000MPa. However, its surface is smooth and its bonding strength with concrete or cement mortar matrix is poor. In order to enhance the adhesion strength of steel fiber and matrix, the shape of steel fiber can usually be changed, that is, the method of producing special-shaped steel fiber can be solved.
The commonly used methods are: (1) pressing edge method. Before cutting the steel wire, the pinch roller of the feed steel wire is used to press the prismatic concave on the steel wire and then cut. (2) Waveform method. Before cutting the wire, use the pinch roller to press the waveform of the wire before cutting. (3) Bending hook method. Before cutting the wire, press out the hook with the pinch roller of the feed wire at an equal distance and then cut off.The end hook type steel fiber is cut by thin steel wire of a certain strength and diameter, the middle is straight, and the two ends are bent into a hook shape; The appearance is smooth and uniform, and it is the most common kind of steel fiber.
