Chrome-plated rollers are suitable for various film production lines, paper production lines, large-scale printing equipment, laminating equipment, widely used in flexographic printing machines, water-based ink printing machines, laminating machines, coating machines, and can also be used for pressing plastics, leather and paper Embossed and frosted.

In most cases, chrome rolls are machined and polished steel rolls with a hard chrome coating on the steel roll body. In most cases, the added coating is bright white. If you look closely, the color is slightly bluish; the thickness of the chrome roll is at least 2 filaments, or 20 microns thick. Otherwise, the hard chrome plating process will not work. The main functions and advantages of chrome rollers are as follows:

1. The advantage of electroplated chrome roller is high hardness. Compared with the actual production and use environment, the hardness after heat treatment is higher than that of alloy steel, as well as other metal steel pipes and round steels of the same grade. After other quenching processes, such as carburizing, nitriding, high frequency and other processes, it is slightly inferior. In actual measurement, the hardness of chrome-plated rolls is generally between 55-65 Rockwell. Non-woven roll

2. High wear resistance and low friction coefficient. Since the hardness of the steel roller body after chrome plating is greatly improved, the friction coefficient decreases relatively with the increase of smoothness, so the service life of the chrome plating roller is correspondingly reduced.

3. The corrosion resistance of acid and alkali is greatly enhanced, because the chromium layer of the chrome-plated roller is very stable in different environments, and it is not easy to undergo chemical reactions, so it will not be corroded by some acid and alkali liquids and gases.

4. Once the chrome-plated layer on the surface of the electroplated chrome-plated roller is damaged, it can be electroplated again to reduce the cost of use and can be reused.

Due to the above advantages of chrome rollers, it has a wide range of applications. Most of the machinery lines will be used to produce mirror and super mirror rolls. In an environment-friendly environment, industrial upgrading is the future trend.
