What is ring rolling?

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.

Controlling the roation speed of main roll

Image
I explained that the rotation speed of the main roll is constant in the ring rolling machine( Rotation speed control of axial roll ). But it isn’t constant in the CALTEK ring mill. I’ll tell you why the rotation speed of the main motor is not constant in our ring mill. Increasing the rotation speed of the roll during rolling can reduce the rolling force because the coefficient of friction between the roll and the workpiece becomes smaller.  That’s why I always ask the ring mill operators to make the rotation speed of the main roll as fast as possible.  However, if the size of the ring is small, the ringmill operator should not rotate the main motor in the maximum speed. I’ll explain the reason with this ring mill belows: * Main motor rpm : 0 ~1,200 * Main roll gear box reducer ratio : 1/40 * Axial roll cone angle : 40 * Axial roll gear box reducer ratio : 1/10 * Axial motor rpm : 0~1,400 * TR range : 200~600 Tis is a graph of the rotational speed of the axial motor according t...

Controlling the movement of the axial stand in the ring mill

Two steps to control the movement of the axial stand in the ring mill We know what the axial stand is and how it moves( Movement of the axial stand in the ring mill ).  As we know, the axial stand moves backward as the ring grows.  And now I’ll explain how the ring rolling machine developers like me control the axial stand’s movement.  You may not be a ring rolling machine develper, but it could be helpful to troubleshoot the problems with axial stand’s movement if you understand how it works and is being controlled. When the vertex of the axial roll coincides with the center of the ring, there’s no slip between the ring and the roll(main roll or axial roll).   So we control the position of the axial stand to be coincided with the center of the ring.  But when the ring grows and reaches the maximun range of the axial roll, we cannot make the vertex of the axial roll be coincided with the center of the ring.  We need to change the way we control the sta...

Movement of the Axial Stand in the ring mill.

Image
What is axial stand? The axial stand supports the axial roll assembly and moves the axial roll assembly as the ring grows.   There are axial rolls, axial roll gear box, axial roll motor and TR in the axial stand. Movement of the axial stand The axial stand is moved by the hydraulic cylinder in the direction of the long axis of the ring mill. I explained in my previous post( Do you know why the axial roll is cone shape? ) that the linear velocity distribution by the main roll and the linear velocity distribution by the axial roll correspond when the virtual vertex of the axial roll(C a ) coincides with the center of the ring(C r ). The ring mill program controls the position of the axial stand so that the virtual vertex of the axial roll matches the center of the ring. As the ring rolling progresses, the ring becomes larger. As the size of the ring increases, the center of the ring moves away from the main roll. As the center of the ring moves, the axial stand ...
