The Production Process of Forged Steel Rings
When forged steel rings are manufactured, open die processing procedures are implemented so that workers can create seamless rolled rings. The unique rolling methods give each ring better concentricity and smoothness. All forged rings can withstand tight tolerances and meet typical industry requirements. Mandrel rings are manufactured for clients who need heavier rings or a smaller supply of rings.
Rolling mills are used when seamless forged rings are made at manufacturing plants. Because the mills are designed in different sizes, the outside diameter of every ring will vary. The smallest rings usually weigh around 300 pounds, and the largest rings often weigh more than 300,000 pounds.
Forged Steel Rings – The Production Process
During the first stage, a circular metal material is transformed into a hollow donut. Workers heat the donut until the surfaces crystallize. Then, the metal is placed in a mandrel or idler roll. Next, the roller travels to the drive roll while under intense pressure. It decreases the thickness of the wall by constantly rotating.
Many manufacturers can make seamless rings in numerous configurations. Most businesses request flat rings, cylindrical rings, and rings that look like washers. The height of each ring also varies; the product can be made one inch high or over nine feet tall. However, the height-to-thickness ratios often range from 1:16 to about 16:1. If a client needs several rings that have bigger proportions, special processing will be required. Usually, rectangular rings are the most common rings because they have a simple design.
