The surface protection behavior of parts made of ferrous or carbon steel grades can significantly increase their service life. The zinc coating is resistant to corrosion and chemically active reagents. It is applied in various ways, one of which is hot-dip galvanizing technology:
- Parts or structural elements, after pre-treatment (cleaning, rinsing, degreasing) of the surface, are immersed in a bath of molten zinc.
- The procedure is carried out at a temperature of 430 to 450 C degrees. The holding time is calculated by the technologist taking into account the steel grade.
The processed part is removed from the bath and cooled in air. The main advantages of hot-dip galvanizing technology - uniform applying a protective layer, filling microcracks and chips with molten metal.
Additional processing
Hot-dip galvanizing technology requires additional processing of the surface of products. It is performed to improve quality characteristics, eliminate the formation of drips and uniform distribution of the protective layer.
Methods are selected taking into account GOST parameters and the geometry of the finished product, as well as the features or production conditions. The following smoothing options are used:
- Mechanical using cleaning materials - asbestos, fiberglass
- Filling - charcoal is backfilled at the point where the part exits the zinc bath.
- Blowing with an air flow - special pneumatic systems are used.
The listed methods of production and additional processing involve the use of special high-tech equipment. Its work can be adjusted both for mass production of serial products and for the production (galvanizing) of small batches of parts.
