Pretreatment device for zinc plating of steel wire

Abstract

The invention relates to the technical field of metal material processing, in particular to a steel wire galvanizing pretreatment device which comprises a treatment tank, a mounting frame is fixedly connected to the top surface of the treatment tank, steel wire guiding mechanisms are connected to the two ends of the top surface of the treatment tank, and a rotating shaft pipe is rotationally connected into the treatment tank; the two ends of the rotating shaft pipe penetrate through the treatment tank and extend out of the treatment tank, a first driving mechanism is connected to the rotating shaft pipe, two first rotating shafts are rotatably connected to the interior of the treatment tank, and a plurality of first stirring blades are fixedly connected to the surfaces of the first rotating shafts in a circumferential array manner; by reducing the rapid temperature change of the plating assisting liquid near the rotating shaft tube, the temperature difference between the plating assisting liquid in the treatment tank and the plating assisting liquid for supplementing is effectively reduced, the rapid temperature change of the plating assisting liquid in a partial area caused by direct mixing is prevented, the influence of the temperature change of the plating assisting liquid on steel wire plating assisting is reduced, and the plating quality is improved. And the subsequent galvanization processing effect of the steel wire is ensured.

Description

technical field [0001] The invention relates to the technical field of metal material processing, in particular to a pretreatment device for galvanizing steel wire. Background technique [0002] The high vanadium closed cable is made of steel wire as the inner core, and the outer layer is twisted with one or several layers of Z-shaped, trapezoidal or other shaped special-shaped steel wire. The actual drawing process of round steel wire drawing to Z-shaped steel wire finally forms the pass pattern of each pass. To form an anti-corrosion coating, before the hot-dip galvanizing treatment, it is necessary to add a plating solution to the surface of the high vanadium wire, so that the parts and liquid zinc can rapidly infiltrate and react. Heat treatment, on the one hand, can fully dissolve ammonium chloride and zinc chloride, on the other hand, the hot water molecules move more intensely, making the solution more uniform, and the composition is more uniform, and it is easy to w...

Problems solved by technology

[0004] In the prior art, when adding a plating flux to the surface of steel wires, usually a plurality of steel wires are passed through a tank containing the flux, and the surface of the steel wires is contacted with the flux to perform fluxing on the surface of the steel wires, but in actual operation During the process, many steel wires are in contact with the fluxing solution, and the consumption of the fluxing solution is relatively large. If the fluxing solution is not added in time, it will affect the subsequent steel wire fluxing, and the addition of the fluxing solution In this case, the temperature difference between the supplementary flux and the flux in the tank is large, and direct mixing will cause rapid changes in the temperature of the flux in the tank, which will affect the reaction effect between the steel wire and the flux, which is not conducive to the subsequent production of the steel wire.
