China Ningyang steel ball: How are small steel balls refined

After drawing and stretching, a slender steel wire transforms into a wire rod with a diameter of nearly 2.5 mm. The wire rod is then forged into a ball blank through a steel ball cold heading machine. The ball blank undergoes polishing, heat treatment, preliminary grinding, fine grinding, etc. After more than a dozen processes, it turns into bright and smooth steel balls with a diameter of only a few millimeters. As the “Hometown of Steel Balls in China”, Ningyang County, Tai'an City has established a complete product production chain for steel ball products, with an annual steel ball output of 850,000 tons.

Not long ago, Yunlian Steel Ball Industry Brain was launched in Ningyang. At present, there are more than 80 companies entering the cloud.
