1. Improve the surface smoothness of galvanized sheet
After smoothing, the flatness of the galvanized sheet has been improved to some extent, the wave shape of the galvanized sheet is partially eliminated, and at the same time, the slag particles or other uneven spots on the surface can be flattened to make the surface smooth and flat.
2. Adjust the surface roughness of galvanized sheet
By controlling the roughness of the work roll surface of the finishing machine, the original uneven roughness of the galvanized sheet surface can be unified to a certain range. This can improve the paintability of the product and the lubricity during processing.
3. Improve the surface color of galvanized sheet
For small zinc flower and non-zinc flower products, the smoothing can make the galvanized sheet obtain a more uniform gloss surface. For some private enterprises using large zinc flower products as color-coated substrates, the zinc flower bumps formed by crystallization and different glossiness of the large zinc flower can be flattened and unified, making the zinc flower blurred and unclear, which is beneficial Cover zinc flower during painting.
4. Improve the processing performance of galvanized sheet
Through smoothing, the yield platform of the galvanized sheet can be disappeared or not obvious, and the metal slip line can be prevented in the subsequent processing.
