Aug 07, 2017

Wire Use classification has: ordinary quality steel wire including electrode, nail, net, packaging and printing wire, cold top forged steel wire for cold upsetting rivets, screws, etc., electrical steel including the production of overhead communication lines, steel core aluminum stranded wire, Steel wire such as special steel Wire, steel wire for textile industry including coarse comb, needle cloth and needle wire, wire rope and spokes, steel wire for the production of steel wires and springs, including spring and spring washers, piano, tires, cords and transport tapes, steel wire, watches industrial steel, ball, automatic machine easy to cut steel wire, Stainless steel wire includes stainless steel wire and surgical implant wire for all uses, Steel wire resistance alloy wire for heater element, resistor element, tool steel wire including steel wire and shoe steel wire.

The main processes of steel wire production include raw material selection, removal of iron oxide skin, drying, coating treatment, heat treatment, wire drawing, coating treatment, etc. Steel wire Removal of oxidized skin The general process is phosphating, the removal of the oxide sheet refers to the removal of the surface of the wire rod or the intermediate strand of iron oxide skin, the purpose is to prevent the drawing of iron oxide damage mold and steel wire surface, Steel wire for subsequent coating or coating preparation of good surface conditions and reduce the tension of the friction to reduce the pull force. There are two kinds of chemical and mechanical methods to remove the oxidized sheet metal, see the chemical descaling and disk strip mechanical descaling. After chemical descaling and coating treatment, the wire rod or the intermediate billet is dried at low temperature to remove hydrogen and moisture. Drying temperature is generally 300 degrees Celsius, the temperature should not be too high to prevent lubrication coating failure. The hydrogen, which is the steel wire, eliminates the hydrogen in the steel base during the pickling process, Steel wire in order to eliminate the hydrogen embrittlement and restore the plasticity of the rod. Remove moisture from the surface of the wire rod so that it dries to prevent the water from deteriorating the lubricant's use.
