Cold rolled plate surface treatment
Cold-rolled plate is a common metal material widely used in construction, automobile manufacturing, electronic equipment and other fields. In order to improve the surface quality and corrosion resistance of cold-rolled plates, appropriate surface treatment processes are required.
(1) Improve the surface flatness of cold-rolled plates. After smoothing, the flatness of the cold-rolled plate is improved to a certain extent, and the corrugation of the cold-rolled plate is partially eliminated. At the same time, it can also flatten the slag particles or other uneven spots on the surface to make the surface smooth.
(2) Adjust the surface roughness of cold-rolled plates. By controlling the surface roughness of the work roll of the finishing machine, the original uneven roughness of the cold-rolled plate surface can be unified into a certain range. This improves the product's paintability and lubricity during processing.
(3) Improve the surface color of cold rolled plates. For products with small bright flowers and no bright flowers, cold-rolled plates can be smoothed to obtain a more uniform glossy surface. For some private enterprises that use large sequin products as the base material for color coating, the unevenness and different luster of the sequins formed by the crystallization of large sequins can be smoothed and unified to make the sequins blurred, which is beneficial to covering the sequins during painting.
(4) Improve the processing performance of cold rolled plates. Through smoothing treatment, the yield platform of cold-rolled plates can be made disappear or not obvious, and metal slip lines can be prevented from occurring in subsequent processing.
The surface treatment process of cold rolled plates is crucial to improving the quality and corrosion resistance of the product. When performing surface treatment of cold-rolled plates, it is necessary to select an appropriate process according to specific needs to ensure that the cold-rolled plates have good surface quality and corrosion resistance and meet various application requirements.
