Short summary
Rotary forging with double symmetry rolls (DSRs) is a new metal plastic forming technology developed on the basis of conventional rotary forging with a single roll, which uses a pair of symmetrical cone rolls to realize continuous local pressure plastic deformation of the workpiece. Compared with the conventional rotary forging with a single roll, it has many outstanding advantages. Rotary forging with DSRs can form large diameter : thickness ratio discs.
