2In the scope, remove a small amount of residue oxide skin that stays after previous step is handled, and activation steel wire surface;
3, washing is removed the steel wire surface because of the residual acid solution of pickling process;
4, the cyanide copper plating process of preplating is adopted in pre-treatment galvanic deposit herein, and bath temperature is controlled in the 30-45 ℃ of scope, and current density is at 1.2-3.0A/dm
2In the scope, the equidistant steel wire both sides that are positioned over of anode copper coin;
5, washing, residual solution in the step in the removal;
6, thick processing galvanic deposit, the equidistant steel wire both sides that are positioned over of anode copper coin, steel wire by 14 identical plating tanks, are carried out the thick processing galvanic deposit of further vitriol and are produced copper clad steel wire continuously, bath temperature is controlled in the 30-55 ℃ of scope herein, and current density is controlled at 5-30 A/dm
2In the scope;
7, washing, the electrodeposit liquid of removal remained on surface;
8, thermal inactivation is adopted in passivation, and temperature is controlled in the 40-70 ℃ of scope;
9, inverted take-up one-tenth dish.
Preferably, the diameter range of the steel wire of described process descaling processing is 6.5mm-20mm.
Advantage of the present invention is as follows:
1, polydisc steel wire line sending simultaneously galvanic deposit, last inverted take-up one-tenth dish packing, so production efficiency height, transportation, convenient storage; The continuous straight line production of copper clad steel wire is so can satisfy the length requirement.
2, as the equidistant steel wire both sides that are positioned over of anodic copper coin, the steel wire level is at the uniform velocity by 14 plating tanks, therefore, the concentration of control galvanic deposit master salt, cathode current density and Trace speed can prepare the copper clad steel wire of copper layer thickness 〉=0.25mm, and the copper layer are evenly distributed, firm binding force, the crooked and several of reeling does not have peeling and peels off; Can prepare the thick copper clad steel wire of 6.5-20mm, the product size scope is wide, can reach grounding wire with requiring.
