Wire surface pretreatment production line

1.Equipment function

The rust removal and cleaning pretreatment of the metal wire surface is to remove the

oxide skin on the metal wire surface, apply a layer of borax on the surface and dry it, reduce

the hairiness and wire breakage during wire drawing, extend the service life of the mold, and

make wire drawing faster and smoother.

2.Equipment composition

Duck-billed wire pay-off →Wire jumbling detection device→Mechanical descaling(dust

removal)→Sand belt polishing machine→Boron coating→High frequency dryer

a. Duck-billed wire pay-off

It can realize automatic paying off and is equipped with an emergency stop device, which

can automatically stop in case of wire disorder to prevent the wire rod from being pulled.

b.Wire jumbling detection device

The function of shelling is to remove the oxide skin on the surface of the base metal of

welding materials, reduce the polishing pressure of the Sand belt polishing machine, facilitate

drawing and ensure good surface quality.

c. Sand belt polishing machine

The Sand belt polishing machine is mainly used for surface polishing in the pretreatment

process of metal wire, replacing the traditional pickling process. The polished wire surface has

no black rust, and the surface is smooth and clean, meeting the production process

requirements of metal wire

d.Boron coating tank

The function of boron coating is to increase the surface lubricant bonding property of the

base metal of welding wire and facilitate drawing. The temperature is required to be about

90 ℃. The heating method is electric heating.

e. High frequency dryer

The function of drying is to evaporate the moisture on the wire surface after boron coating,

so as to ensure the life of the drawing die. Its working principle is to heat the wire rod by

high-frequency induction and evaporate the surface moisture of the base metal to ensure the

smooth drawing process.Automatic temperature control, which can display the current drying

temperature.
