Profile Ring Rolling

#RingRolling, #Forging 1. Structure and shape of main roll The main roll has a cylindrical shape and has a hole with a key way to assemble the rotating shaft.   The main roll is rotated by the motor and reducer.  The rotation speed of the main roll varies depending on the size of the ring mill equipment, but it usually rotates at 20-40 rpm.  The smaller the ring mill, the faster the rotation speed of the main roll. The general main roll is a simple cylindrical shape, but the main roll for producing a profile ring with a complicated sectional shape varies depending on the product shape. 2. Functions of main roll The main roll is the most important part of the ring mill.  The main roll is the reference point for measuring the dimensions of the ring.  The outer diameter of the ring is measured from the surface of the main roll. A torque is generated that rotates the rolling ring from the main roll.  On the opposite side of the r...

Ring rolling is a process to increase the outside diameter by reducing the cross-sectional area of donut-shaped ring. We can produce seamless ring products through ring rolling process. * initial state of ring rolling 1. Main roll rotates the ring 2. Mandrel Bar goes to mainroll side reducing the radial thickness of the ring 3. Axial Roll goes down reducing the axial thickness of the ring.  Axial Roll rotates the ring. * final state of ring rolling 1. The cross-sectional area of the initial material(Blank) decreases and the outer diameter increases.
