How does the cooling roller work?

 
We all know that the development speed of roller products has been very rapid in recent years, so many different roller products have appeared. According to different production and processing needs, different roller products will be used. As a kind of roller, how does the cooling roller operate during use? Professional roller manufacturers focus on the processing, production and use characteristics of roller products. They still have a say. They have their own ideas about the use of rollers. How does the cooling roller work specifically? Now let’s take a brief look at it and understand these so that it can work smoothly.
 
There are different requirements for the selection of cooling roll speed ratio according to different production and processing activities. Some people believe that shear force with a smaller speed ratio can promote further plasticization of pellets during cold rolling. In fact, this plasticizing effect is very small, but it will cause scratches on the surface of the magnetic plate and amplify small defects due to the shearing effect of the cooling roller differential speed.
 
After calculation and experimental testing, the aspect ratio of the cooling roller is 2.5~3, the middle height is 0.1~0.3‰ of the roller diameter, the roller surface temperature is 60~80℃, the linear speed is ≤3.5m/min, and the speed ratio is 1:1 , and equipped with edge scraping equipment, roll surface temperature and roll gap display equipment. The criterion for setting the cooling roll planning parameters is to complete one rolling step as much as possible to produce qualified magnetic plates. The internal residual stress of the magnetic plate that has been repeatedly cold-rolled is very large. After bonding with the PVC film, due to the difference in shrinkage rate between the two, the PVC film and the magnetic plate will be debonded, and the PVC film and the magnetic plate will appear at the edge of the magnetic plate. Flat scene. If the products produced through cooling roller processing are implemented in accordance with relevant specifications, the quality of the products produced is still guaranteed.
 
During the working process of the cooling roller, in order to make our cooling roller work reasonably, we need to select the appropriate speed ratio and processing frequency according to different processing activities, and control all parameters in place so that the cooling roller can operate normally. Facing different roller product processing activities, roller manufacturers have professional technical personnel to provide guidance. If necessary, you can contact us.
