1, reduce the hot wire with iron ions in the plating agent, reduce the generation of zinc slag. The use of the invention patent technology, regularly put zinc block to the plating agent pool, so that the plating agent in the bivalent iron into trivalent iron, and play a stable PH value within a numerical range of an important measure, but also easy to filter out the filter trivalent iron ions in the plating agent; The ferric ion is controlled between 0.3 and 1.0g/L. When the plating agent is not released in the hydrogen, then continue to put zinc blocks. It is an effective measure to reduce zinc slag, improve the fluidity of zinc liquid and reduce the thickness of zinc layer to give full play to the role of filter of plating aid.
2. It is forbidden to fish out the lump of zinc and sell it as zinc ash. After the zinc ash should be brown yellow real zinc ash, zinc surface, effectively reduce the zinc consumption. This is one of the biggest measures to reduce zinc consumption, but it is also a real problem, which has not been solved for many years. Keep the wire rinsing water clean after pickling. The management system of rinsing water after pickling of steel wire should be discharged regularly and regularly, and the rinsing water should be kept clean and low acidity as far as possible. It is more appropriate to control pH 3.
3, according to the wire diameter of the wire to adjust the zinc immersion time. Zinc immersion time should be adjusted according to the diameter of the wire. The method of adjustment is to use the lead screw on the zinc pot, the length of the distance to the ceramic sink roller. The zinc immersion time of thick wire diameter should be long, and the zinc immersion time of fine wire diameter should be short, and the zinc immersion length should be in the range of 2~3.5m, which is also to reduce the zinc consumption of steel wire galvanizing and maintain the uniformity of zinc layer.
4, eliminate zinc liquid surface agglomerate zinc residue. With a large pickpocket for steel wire, into the zinc liquid in front of the zinc ash stirring; Use a small one for the exit of galvanized steel wire; Zinc pot wire outlet to be in 30 minutes, with pickpockets back and forth, until the large, floating zinc residue into brown yellow, real zinc ash, zinc ash surface.
5, the concentration of plating agent can not be too high. The concentration of plating aid should not be too high. Hot wire plating must be in accordance with the data of laboratory analysis to add ammonium chloride and zinc chloride, the proportion of the composite solution control in the range of 50~80g/L. Adding ammonium chloride or zinc chloride raw materials without the results of laboratory analysis should be criticized and educated, and economic treatment should be given when necessary.
