Production Process

The production of wire rope welded steel wire has three basic processes of drawing, twisting and tying.Wire drawing raw materials: wire rope welding wire drawing here refers to a process in which raw materials are pickled, phosphatized, shelled, and opened, and one or more pull-ups are carried out to change the molecular mechanism to reach the target diameter. means. The raw material has a ferrous metal of 0.14 to 10.00 mm and a non-ferrous metal having a diameter of 0.01 to 16.00 mm. Pickling: Washing the surface of the steel wire and welding the surface of the steel wire with the acid rust and rolling. In the steel wire welding wire production process, it is also called shelling. The high-line oxide is mainly stripped to prevent the rust and other impurities from affecting the blanking. Damage to the drawing die.

Phosphating: In layman's terms, the process of immersing a material in a phosphate solution to obtain a layer of water-insoluble phosphate film on the surface. Prevent corrosion to a certain extent. Blanking: A well-shaped hole in the center of a mold that draws a metal wire, round, square, octagonal, or other special shape. The size and shape of the metal change as it passes through the die hole.

Cold wire drawing: ordinary round steel, let it be forced through a hole smaller than its diameter, the diameter of the round steel will become smaller, the length will be extended, and the process will be repeated, the round steel will Further smaller. After the plastic deformation occurs, the hardness of the steel material increases, and the plasticity substantially disappears. If steel is not required and strength is required, such a steel can be used.
