galvanized coils, the sheet steel is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ℃ to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.
Plating Definition
(1) Spangle coating of normal spangle coating
In the normal solidification process of zinc layer, zinc grains grow freely and form a coating with obvious spangle morphology.
(2) Minimized spangle coating
During the solidification process of the zinc layer, the zinc grains are artificially restricted to form the smallest possible spangle coating.
(3) Spangle-free spangle-free coating
is obtained by adjusting the chemical composition of the plating solution, and has no visible spangle morphology and a uniform coating on the surface.
