5.Working Process
5.1 Diagram of working Process
5.2 Unprocessed parts inspection
5.2.1 All the galvanized product should be visual check before zinc coating.
5.2.2 Extra work need to be done if follow situation occur while unprocessed
parts checking(or Special technique need to be done )

5
1）Dimension of work piece beyond the zinc plating pot
2）Work piece without vent, half closed leakage of liquid zinc hole or
fully closed plating, and no suspension pints.
3）Welding seam of coated parts that is not closed, welding coating
and slag of welding seam does not clean, as well as more serious defect of
coated parts.
5.3 Hang material
5.3.1 Plating rack should be inspected before hang
materials,deformation.cracks.tripping, corrosion and surface adhesion large
area with zinc layer is found and, may not continue to use.
5.3.2 Sort component according to the type.length.materials and surface
condition while hanging.
5.4 Pickling
5.4.1 Hydrochloric acid aqueous solution is used for pickling, hydrochloric
concentration is 40~160 g/l, room temperature as working tempreture.
5.4.2 Compound of pickling liquor
32% industrial concentration hydrochloric acid, 1:1 mixed with water to
produce hydrochloric acid content of 160 g/l concentration of acid pickling
solution. Preparation before adding water and then adding acid, add tube
immersed in the water of hydrochloric acid, and acid fog inhibitor (otherwise
stated) During the pickling liquid in use generally do not add acid until the
reduced content of 40~45 hydrochloride g/l of solution concentration and
solution of ferrous chloride (FeCL2) content of up to 200 g/l, pumping of
waste acid storage tank, and processing.
5.4.3 Acid pickling solution testing once for each class,result posted on the
signs to guide the pickling operation treatment.

6
5.4.4 Pickling time is made according to the plating surface oxide layer and
acid concentration. Pickling operation to speed up the reaction speed,move
from top to bottom plating in acid pickling process must be two to three times,
and then pull above fluid level to check quality of pickling
5.5 Rinsing
Qualified rinse galvanized components must be rinsed in the double
rinsing craft tank through flowing water to erase the surface remaining
pickling liquid and other debris, and then immediately into the plating bath by
flux process.
5.6 Fluxing
5.6.1 Plating agents are ammonium chloride (NH4CL) solution, the working
temperature is 60~80℃, proportion is the solution: 1.03~1.05g/cm3 (room
temperature measurement). Plating agents used in the process should be
supplemented and adjusted in proportion within the limits prescribed.
Assistant pools keep the water level of the low water line and between the
highest water level.
5.6.2 Flux test for twice each batch, its iron content in solution at 10
grams/liter. PH=3~5, quality control. Assistant quality control in the
regeneration cycle, flux heating by heater.
5.6.3 Full immersion plating after rinsing solvent treatment in plating solution,
soak time of 3-5 minutes.
5.6.4 Work piece treat after flux,, chemical treatment and quality inspection is
needed.. Local paint or for any other reason fails to acid clean surface
grinding wheels, wire brushes, scrapers and other tools for processing,
repeat the pickling process operation, rack zinc plating after chemical
qualifying.
5.7 Second-hanging Before Galvanizing

7
5.7.1 If pickling qualified, the work piece which well handled after plating auxiliary should
go on to proceed second-hanging before galvanizing.
5.7.2 Pay attention to the position of hole and characteristics of work piece while
second-hanging and select the applicable hanging point and right direction of zinc flow in
case of any quality problem such as unfavorable air-out, smooth zinc flow and zinc
heaping etc. Second-hanging should reach hot-dip galvanizing requirement.
5.8 Preheating & Drying
After second-hanging procedure, stay in drying tank and make sure the work piece
dry enough and then go on to do hot-dip galvanizing.
5.9 Hot-dip Galvanizing
5.9.1 Zinc Bath
5.9.1.1 Zinc bath is mainly composed of molten zinc. The chemical ingredients of zinc
ingot have to reach GB470 standard. Add proper aluminum alloy in zinc melt which
should net exceed 50g/ton(zinc).
5.9.1.2 Galvanizing work should be started as long as the zinc melt temperature up to
455℃-460℃. Meanwhile, the temperature should stay between 420℃ ～ 430℃ if
production paused.
5.9.1.3 Fill the zinc everyday while off work to make sure lower the pressure of zinc
melting pot and stay 10-30cm distance between zinc melt and edge of zinc melting pot.
During special producing situation in large use of zinc should fill at anytime.
5.9.1.4 Thickness of the residues in zinc melting pot cannot over 8cm to lower the
possibility of zinc pot corrosion. To do at least twice totally salvaging zinc residue work
each week, the salvager should salve evenly from one side of the pot to another side
and each time should repeat one third of the site where have been salved already. If
miss any work-piece into the zinc pot, salve immediately to avoid corrosion and produce
much more zinc residue.
