What are the two working methods of the packaging steel strip finishing machine?
The finishing machine has two working modes: dry finishing and wet finishing.
When the smoothing machine is working, the slag particles and impurities on the surface of the galvanized sheet will be crushed off and stick to the roller, and the dust in the air will also fall on the roller. Due to the high pressure during smoothing, even the extremely small dirt on the roller surface will leave a more obvious imprint on the surface of the galvanized sheet, which will affect the appearance of the product, so it must be removed.
Dry finishing uses roller brushes to remove dirt on the surface of the rollers. This method makes the finishing system simple to distribute, and it can also prevent the parts from being immersed in water to produce rust. However, in actual use, it is found that only the brush roller cannot completely remove the dirt on the roller surface. It must be supplemented by a water spray method, that is, a wet smoothing method.
Wet smoothing is to spray desalinated water or special smoothing fluid on the surface of the work roll on the side of the population to clean and remove the dirt on the surface of the work roll. At the same time, it can also play a certain lubrication effect during smoothing to reduce rolling. The braking force and the wear of the roller surface. This not only improves the surface quality of the product, but also prolongs the life of the work roll, which is widely used in practice.
The wet finishing system must add nozzles, water squeezing and drying devices.
