Hot dip galvanizing galvanizing Line
0.8~2.0mm*700mm 150,000TPY ( steel metal)
Beijing JJRS Technology Development Co., Ltd. registered in
national high tech park-Beijing Economic and Technological
Development Zone, is high-tech enterprise specialized in the
complete set of metallurgical equipments, intensive processing of
steel strip and metal surface coating engineering project, with the
integration of mechanism, optics, electric and hydraulic pressure.
JJRS is professional on turn-key projects, from general planning,
designing, to manufacturing, installing, commissioning and
servicing. Besides, our business also covers single equipment’s
designing, manufacturing and installing, as well as electric
transmission, control system and spare parts. All basing on these
supporting businesses, we mark out a developing strategy that
taking metal strip intensive processing and color coating
production lines as main, and the associated industry products as
supplement.Consolidating the advantages of the traditional technology "
The Sendzimir method consists of hot dip galvanizing before
processing. The process consists of a treatment that involves the
passage of the sheet metal in a bath of molten zinc at 650°. Before
passing through the zinc, the sheet is subjected to a degreasing
treatment to remove surface impurities and then pickled in
hydrochloric acid to eliminate iron oxides. The total zinc
thickness on both sides ranges from Z 200 to Z 275 g/m2 (UNI EN
10346).
Galvanic coatings offer triple protection to the steel underneath:
Protection by barrier effect: the coating insulates the steel from
the external corrosive environment.
Cathodic or sacrificial protection: Zinc forms the anodic part in
the corrosion stack and corrodes slowly protecting the steel. As
long as there is zinc on the surface, the steel will not suffer any
corrosion.
Sealing of uncovered areas: The zinc corrosion products, which are
insoluble, compact and adherent, seal the areas of the steel which,
for whatever reason (shocks, scratches, etc.), accidentally has
been exposed to the external environment. This procedure provides
additional protection for the substrate.
Research & Development Objective of " JJRS-Sendzimir"
Genuine heat regenerative non-oxidation heating
Waste heat "extreme recycling"
No end in energy conservation and environmental protection
Two Core of " JJRS-Sendzimir"
Compared with the traditional technology, " JJRS-Sendzimir" method
can greatly increase productivity. For its:
- High temperature flame on-time heating technology: In the heating
furnace, steel strips from the normal temperature of 20 C can be
heated directly to the re-crystallization temperature zone of strip
steel in the non-oxidation atmosphere.
- Zero heat preservation and energy saving concept: On the premise of
guaranteeing the annealing and restoration effects, heat energy can
be reasonably allocated, steel strip heating is conducted as far as
possible in the flame heating section of high thermal efficiency to
shorten the length of reduction section, so as to improve
productivity as much as possible and reduce the manufacturing and
operation cost of spare parts
