Four major functions of galvanized coil surface finishing

1. Improve the surface flatness of galvanized sheets. After smoothing, the flatness of the galvanized sheet has been improved to a certain extent. The corrugation of the galvanized sheet has been partially eliminated. It is also necessary to smooth out the slag particles or other uneven spots on the surface to make the surface smooth and smooth. Spend. 2. Adjust the surface roughness of the galvanized sheet surface. By controlling the surface roughness of the work roll of the finishing machine, the original uneven surface roughness of the galvanized sheet surface can also be unified to a certain range. This can continuously improve the paintability of the company's products and the lubricity during processing.

3. Continuously improve the surface color of galvanized sheets. For zinc and zinc-free enterprise products, smoothing can also make the galvanized sheet have a smoother and more consistent surface. For some private companies that use large zinc flower products as color-coated boards, the large zinc flowers can achieve smoothness and uniformity due to the zinc flower bumps and different smoothness caused by crystals, making the zinc flowers become more and more molded. A fuzzy paste that helps cover up splatter when painting. 4. Continuously improve the performance of galvanized sheet processing plants. Through smoothing, the compromise platform of galvanized steel sheets can also be made invisible or inconspicuous, which can avoid causing metal slip lines in subsequent processing plants.
