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.
