- Galvanizing is
a process in which a zinc film is deposited on goods made of steel
to provide long term (generally 10 to 30 years) corrosion protection
and abrasion resistance.
- A complete
logistics structure, the entire plant infrastructure and the
processing technologies of a hot dip zinc galvanizing facility is
developed. Some essential methods of a Design for Reliability
Approach (DFR) are
applied during the development of the logistics infrastructures of
the new facility.
- The protection
of steel from corrosion by hot dip zinc galvanizing is a well
established practice and the technique is still unequalled for the
long term protection of structural articles.
- Worldwide, the
largest markets for galvanized steel are mostly the “Construction
industries” and the “Automobile industries”. The recycle life of
galvanized steel can be up to 100 years and the added cost is
justified by decreased maintenance cost over non-galvanized steel.
- The normal
procedure for flux galvanizing of steel sheet involves a
cleaning/degreasing step, often using a
similar aqueous alkaline cleaning solution as that used for the
hydrogen cleaning process.
- A new
precision zinc galvanizing process has been developed providing
superior wear and corrosion protection on steel and iron parts. The
process eliminates environmental problems with traditional hot dip
galvanizing and zinc electroplating processes.
residues, which have a high zinc content, are totally recycled. As a
result, these materials, of which 800kt are produced each year
worldwide, constitute 54% of zinc-containing materials (new zinc
scrap and residues) currently recycled.
general galvanizing plants, which protect about 5Mt steel products
each year, do not generate
galvanizing processes produce zinc-containing materials, or
by-products, known in the industry as
residues. The first, known as galvanizing dross, comes from the
reaction of zinc with the steel which is
galvanized. The second, known as skimmings or ash, comes from the
oxidation of zinc during the galvanizing
- The properties
of these galvanizing by-products are well known and there are well
established technologies to comple-tely recover the zinc contained
