WhatsApp: +86 18221755073The process and equipment are similar in principle to rolling mills used for plate. In both processes, the metal is rolled between two rolls, which move toward each other to form a continuously reducing gap. In ring rolling, the rolls are of different diameters. The process is shown schematically in Figure 1-5, Section 1.
