1) The need to consider the elongation of
steel, 450 ℃ hot
dip galvanized steel elongation of 5mm / m.
2) The need to consider the thick pieces and thin pieces of galvanized heating
time is different, which will lead to the linear elongation of different
components.
3) Considering the speed of the steel immersed in the zinc bath can reduce the
stress generated during the galvanizing process, requiring the design of steel
as much as possible into the liquid inlet and outlet.
4) Suitable for hot-dip galvanizing process substrate is only steel matrix.
5) Low internal stress of the substrate or component is suitable for hot-dip
galvanized, may be the case should be avoided cold-formed components of hot-dip
galvanizing.
6) If the required components in the manufacturing process does not produce
stress, can be designed to use welding forming process.
7) Remove residues from the surface of the steel substrate (slag / coating,
etc.) which would otherwise interfere with the interfacial reaction of the hot
dip galvanizing process.
8) To be plated components should be designed as symmetrical structure.
9) possible to avoid the existence of large thickness difference between the
substrate transition (maximum not more than 1: 2.5)
10) Take into account the size of the
hot-dip galvanizing pot used.
11) Try to avoid multiple dip.
12) When the plating plate components, should be used to eliminate the tension
straightening method of structural twist.
13) The use of diagonal edges or the entire board pre-deformation method
control due to hot-dip galvanizing may be caused by the board folds or
stretching deformation.
14) Avoid dead spots or dead spots in the structure
15) Large structures should be broken down.
16) For the tubular structure, should be set up a reasonable flow port.
17) For hollow container-like structures, the size and number of flow ports
should be designed.
18) The difference in density between steel and molten zinc should be
considered.
19) For heavy steel structure should be set up to facilitate the use of the
suspension device.
20) Does not allow the epitaxial welding of steel profiles, if necessary, to
eliminate the stress treatment.
21) To consider the lifting capacity of existing plant lifting equipment.
22) Prior to hot-dip galvanizing, a special agreement must be signed with the
hot-dip galvanizing company.
