The significance of hot-dip galvanized steel coil
Cold-formed thin-walled steel has been generally used black material, after cold-rolled through a simple rust coating process go into service, and its service life is subject to certain restrictions (usually in about 5 years there will be a large area of rust). The company introduced to the market galvanized steel coil,based on hot-rolled strip, pickling, cold-rolled, heating and reduction, galvanized and other processes produced, and its products can reach the standard GB510018-2002 " technical specifications Cold-formed thin-walled steel structure," is mostly used in the construction industry , but also in the automotive, railway locomotive manufacturing, warehouse board manufacturing, highway guardrail and other industries.
- galvanized steel coil method of Galvanized strip 1
- Galvanized Hydrogen reduction method
Galvanized hydrogen reduction is invented in 1937, hydrogen reduction method of hot-dip galvanizing laid the basis for a modern continuous hot-dip galvanizing.Production by technology Hydrogen reduction method, the appearance of quality, bonding of zinc layer are better than the solvent method of galvanizing. Galvanized Reduction method in steel strip after pickling into the heating reduction furnace, with hydrogen after restoring produce oxide film , and in pickling and heating reduction process to produce a layer of sponge-like steel surface layer, into the zinc pot can produce a layer of zinc-iron alloy layer with good bonding strength and uniformity, which greatly increases the adhesion of the zinc layer, which also determines the high energy consumption cost of the zinc plating method.
- Galvanized steel coil solvent method Ammonium chloride
Galvanized solvent method Ammonium chloride was invented in 1837. The product by technology solvent method Ammonium chloride , due to the Galvanized solvent method Ammonium chloride without heating reduction process, the appearance of the quality and galvanized surface adhesion is worse than Galvanized Hydrogen reduction method . This also determines the cost of energy consumption of its zinc plating method lower than galvanized hydrogen reduction .
三、 galvanized amount of Galvanized steel coil sheet is generally 180-220g / ㎡, in the wet southern region can increase the amount of galvanized to 275g / ㎡ to improve the life of steel components. The life of galvanized products is generally 20-25 years.
四、 characteristics Zinc layer of galvanized steel
Electro-galvanized layer can not form zinc spangle, hot-dip galvanized layer has zinc spangle, the formation process is as follows:When the galvanized strip comes out from the zinc pot, a large amount of zinc liquid is blown back to the zinc pot by blowing of air knife. At this moment, there is still pure zinc layer on the surface of the steel strip, which is attached to the surface of the steel sheet by the liquid state to form a large amount of crystals on the surface of steel sheet , with the steel sheet cooling up, so that the crystalline nuclei slowly grow into zinc spangle.The faster the cooling rate, the smaller the zinc spangle, the slower the cooling rate, the greater the zinc spangle.
Zero spangle galvanized sheet:
In fact, Zinc spangle has only ornamental value, no practical value, on the contrary in the anti-corrosion is not good, in developed countries have implemented small zinc spangle and zero spangle galvanized steel sheet.

Grades and technical requirements Galvanized
1、 Nomenclature grades of Galvanized steel sheet and steel strip
Common brands DX51D + Z, DX52D + Z, DC51D + Z, DC52D + Z, S350GD + Z and so on. Grades of Galvanized steel sheet or steel strip consists of five parts: the product usage code, steel grade code, Characteristics of steel , hot-dip galvanizing code (D), +, zinc coating class code , the Named Methods of details brand as follows:
A） Galvanized sheet using Cold forming :
For example: DX51D + Z (or ZF \ AZ), DC51D + Z (or ZF AZ), DD52D + Z (or ZF AZ) DX: The first letter D is flat steel for cold forming, the second letter If it is X, it means that the rolling state of the substrate is not defined; if the second letter is C, it means that the substrate is a cold-rolled ; if the second letter is D, it means that the substrate is a hot-rolled substrate;
51 ~ 57: two digits that the steel grade serial number; after two digits D is hot-dip galvanized code;
Z indicates that the coating is pure zinc, ZF indicates galvanized iron alloy and AZ indicates aluminized zinc.
So: DX51D + Z says the product use for cold forming, flat steel, not specified substrate status, steel grade serial number 51, pure zinc coating, hot-dip products. B) Other galvanized grades naming example
Characteristics are not specified, D is hot-dip galvanized, and + Z is zinc-plated
HX340LAD + ZF: It is used for high-strength flat steel for cold forming. It does not specify the state of the substrate. The minimum yield strength is 340Mpa. The type of steel is high-strength low-alloy steel, zinc-iron alloy plating and hot-dip galvanized steel. HC340 / 590DPD + Z: that the product is used for cold forming, high strength flat steel, the provisions of the substrate for the cold-rolled substrate, the minimum yield strength value of 340Mpa, provides the minimum tensile strength of 590Mpa, steel type duplex steel, Pure zinc plating hot-dip products.

（6） No treatment (U)
When ordering, it must be stated in the contract. In this case, the surface of steel sheet and steel strip will be more easily to form white rust and black spots on the surface during transportation and storage. Users should be cautious in the selection.
四、Classification of Galvanized sheet
1 Classification as galvanized substrate (1) galvanized carbon steel
Continuous aluzinc steel coil mostly use mild steel, the carbon content of 0.10% -0.20%, galvanized features and industrial pure iron is very similar. In the ordinary low-carbon steel as a substrate for hot-dip galvanizing, the composition of the most influential elements are carbon and silicon. In general, the higher the carbon content in the steel, the stronger the zinc-iron reaction, the greater the iron loss, and the thicker the resulting alloy coating, making the coating brittle, poor plasticity, poor adhesion of the coating. In addition, the high carbon content of steel will also affect the surface quality of the coating, often with missing plating point, but also easy to form zinc tumor.
With the development of the automotive industry, more and more requirements are put forward on cold forming properties such as deep drawing of general carbon steel. The carbon content in the steel is expected to be as low as possible. For example, the carbon content of a stamping steel is generally less than 0.10%, and the commonly used carbon The content of carbon is not more than 0.04% (such as K08Al), while the content of ultra-deep-drawn steel (such as interstitial-free IF steel) is up to 0.005%.
(2) High-strength Prepainted steel coil In order to meet the needs of the automobile manufacturing industry such as weight reduction, energy conservation and safety, one of the major users of hot-dip galvanized steel sheets, the hot-dip galvanized steel sheets for automobiles, which are based on high-strength steel sheets, have been rapidly developed. At present,in abroad have developed or are being developed high strength steel IF high strength steel, bake hardened steel, low alloy high strength steel, dual phase steel and phase change induced plastic, carbon and manganese high strength steel, martensitic steel, The achievable intensity levels are shown in Figure 1.

2 Classification according to the coating (1) the classification according to of zinc spangle A Galvalume steel coil with large zinc spangle.
This is one of the most original production of galvanized steel, as we all know, zinc ore and lead ore total symbiosis, in the smelting of zinc, it is impossible to remove all lead impurities, the content of 0.05% or more can be formed large zinc spangle.
Each zinc spangle, the crystallization center is raised, the edge is concave, the surface is uneven appearance, which is not conducive to its subsequent processing and coating. In addition, due to the low amount of lead in zinc solid solution, it will be precipitated in the grain boundary when cooling, resulting in stress and electrochemical corrosion at the grain boundaries, galvanic intergranular corrosion, reducing its corrosion resistance. Therefore, in recent years, people have gradually got to know it. The galvanized sheet with large zinc spangle will be gradually eliminated.
