What Is The Meaning Of Galvanized Light?

- Jun 20, 2017 -

With the continuous expansion of the use of hot-dip galvanized steel plate, in the modern continuous hot-dip galvanizing unit, through the steel strip can achieve the following purposes:

(1) To improve the flatness and flatness of the sheet, but also to the surface of the zinc particles to flatten, so that the surface of the strip smooth, which for the future of the deep and other use of high precision occasions are particularly advantageous.

(2) The use of the finishing roller, after the advance shot peening treatment, and thus through the finishing of the surface of the plate has a certain degree of roughness. It can improve the adhesion of the coating, but also can store a certain amount of grease, in the deep stamping process, the lubrication of the hedging model is beneficial;

(3) For later paint treatment of the plate, although the surface control into small zinc flowers, but small zinc flowers can still be exposed through the paint layer. Therefore, for some of the requirements of high galvanized sheet, the surface of small zinc flower need to be treated by light. This allows the galvanized plate to obtain a more uniform and consistent silvery appearance.

(4) Through the light, the lower yield point can be reduced, so that the yield platform disappears or is not obvious, can prevent in the later stretch or deep stamping process when the slip line, improve the depth of the potential.
