introduction.Degreasing: remove the uneven soap powder and borax,
and paint a layer of soap powder and borax on the surface of bright
steel wire, so that the surface coating of steel wire is more
uniform.Furnace: make the deformation hardening steel wire to
restore the ductility, and obtain the ideal microstructure to meet
the cost of steel wire in tensile strength, shape, elongation and
other requirements.Quenching: the heat-treated steel wire is cooled
down from high temperature, and the water vapor quenching process
is used to obtain strong strength and shaped sostenitic
structure.Pickling: remove all oxides and residues on the surface
of the steel wire, and the clean surface is conducive to uniform
coverage of the rear coating.Copper plating: a layer of copper is
uniformly plated on the surface of the steel wire, so that the
subsequent brass is conducive to drawing.Zinc plating: deposition
of metal zinc on the surface of steel wire.MF: the method of
intermediate frequency heating makes the copper and zinc layers of
steel wire diffused with each other to get brass. The effect of
intermediate frequency annealing is to raise the surface of the
steel wire to a certain temperature to make the zinc and copper
mutually diffused.Phosphoric acid wash: remove the zinc oxide
produced on the surface of the steel wire in the intermediate
frequency thermal diffusion stage, which is hard and not easy to
deform. Too much zinc oxide will lead to broken wire in the wet
drawing process. 4.Product applicationTire meridian, cutting
steel wire, diamond busbar, hose wire, etc. 5. Our ServicesIn
