Functions of optical finishing include:

  1. Improve the shape and flatness of the plate.

2. Reduce or eliminate the yield platform of the steel plate, so that the phenomenon of slippage line caused by the coated steel plate in the forming process is temporarily reduced, lightened or eliminated.The yield platform is temporarily eliminated by large amount of photofinishing, which can be maintained for several days.

3. Press the plating wafer flat to reduce the fluctuation of the coating surface.Here say "crystal flower," rather than "zinc flower", because: the crystallization of the galvanized layer of pattern is called zinc flower, if the other kinds of hot dip plating crystalline pattern, also known as zinc flower is not appropriate, but all kinds of hot dip plating crystallization can generally referred to as the crystal flower designs..

4. Fine,1 thick mallet.This important thing is done by calling y to beat hair, electric fire to beat hair or laser to beat the temple force 1, the entire surface of the work roll of light wool.The working roller with different surface roughness will give different surface roughness to the plating plate.However, the coating, the surface roughness of the plate is not equal to the surface roughness of the working roller, because after the leveling processing, the elastic deformation of the plate surface disappears, only.Plastic deformation is preserved.The "copy coefficient" is generally 0.5~ 0.6, that is, the roughness formed on the surface of the plate is the smooth working roll, and the roughness of the roll surface is 50 ~60%.

Optical integrity elongation (also called flatness): maximum 2%.
