About Prime hot dipped galvanized steel coils
Prime hot dipped galvanized steel coils are widely used in many fields due to their good corrosion resistance and formability. The corrosion resistance of zinc in the atmosphere is tens to hundreds of times stronger than that of steel, and the electrode potential of zinc is lower than that of iron, thus playing the role of addition and cathodic protection. It has the function of isolation protection. The structure and phase distribution of the zinc coating will affect the corrosion resistance of the zinc coating. The influence of the texture of the zinc coating on the corrosion resistance is mainly because the different crystal orientations of the zinc coating will cause different atomic binding energies on the atomic surface. The atomic binding energy of the low-index crystal face is larger, and the corrosion resistance is better. The formation of the hot-dip galvanized alloy phase is mainly carried out by the thermodynamic diffusion of zinc atoms and iron atoms, so the formation of the alloy phase needs to be carried out at Itgher temperature. , it can be seen that the thickness of the alloy phase is mainly related to the temperature of the hot-dip galvanized zinc solution and the time of the steel plate in the zinc solution. The temperature, composition, and time of the two kinds of hot-dip galvanized zinc solution is the same. Hence, the difference in the alloy phase thickness of the two kinds of hot-dip galvanized sheets are also very small.
Production Process
Decoiler——Entry Looper——Pretreatment——Annealing Furance——Zinc Pot——Cooling Tower——Water Quanac Tank——Skin Pass——Tension Leveler——Passivation——Exit Looper——Roller
Package
It is divided into two types: galvanized plate cut to sheet and coiled galvanized sheet packaging.
General iron packaging
lined with moisture-proof paper
Bound with iron waists
tied firmly
To prevent the internal galvanized sheet from rubbing against each other.
