  • Radial rolling process for ring product that can control strain distribution of ring product
    Patent number: 10173256
    Abstract: The invention provides a radial ring rolling process for controlling strain distribution of a ring product. In the process, a ring blank is rolled by a main roll and a mandrel that are driven to rotate, while a gap between the main roll and the mandrel continuously decreases in the radial direction of the ring blank. The process includes (A) according to dimensions of the ring product and expected strain, a rolling ratio is firstly determined, dimensions of the ring blank is calculated based on the rolling ratio and the dimensions of the ring product; (B) a rotation speed curve of the mandrel is determined based on the rotation and the radial feeding speeds of the main roll; (C) the ring blank is rolled according to the rotation and radial feeding speeds of the main roll and the calculated rotation speed of mandrel in step (B).
