Drawing process of galvanized steel wire(3)

Mixed plating and DRAWING PROCESS: IN order to produce ultra-high strength (3000 N/mm2) galvanized steel wire, the "mixed plating and drawing" process should be adopted. The typical process is as follows: lead quenching - one drawing - pre-galvanizing - secondary drawing - final galvanizing - three drawing (dry drawing)- water tank drawing a finished steel wire. The above process can produce ultra-high strength galvanized steel wire containing 0.93 to 0.97% carbon with a diameter of 0.26 mm and a strength of 3921 N/mm2. The zinc layer can protect and lubricate the surface of steel wire during drawing, and no wire breakage occurs during drawing.
