Galvanizing
Galvanizing is a reliable technology to coating metal part what has been wildely used in industry, civil and mechanical engineering. It is efficiant to Improve corrosion resistance of steel components in humid environment for a long period.
Hanging
All steel parts are hanged on the beam and they are prepare to be moved in the hydrochloric acid bath.
Move in Cleaning Workshop
Hanged steel parts are shifted in the cleaning workshop and prepare for next step of processing.
Soldering
The galvanizing reaction will only occur on a chemically clean surface. In common with most zinc coating processes, the secret to achieving a good quality coating lies in the preparation of the surface.
Galvanizing
When the clean iron or steel component is dipped into the molten zinc (which is commonly at around 450°C) a series of zinc-iron alloy layers are formed by a metallurgical reaction between the iron and zinc. The rate of reaction between the steel and the zinc is normally parabolic with time and so the initial rate of reaction is very rapid and considerable agitation can be seen in the zinc bath.
Post treatment
Post galvanizing process treatment can include quenching into water or air cooling. Conditions in the galvanizing plant such as temperature, humidity and air quality do not affect the quality of the galvanized coating.
