The specification of the ring mill

When we say the specification of the ring mill, we say H110/V90-Φ2,000/500.
Do you what does it mean?

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 ...

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...

The linear velocity of main roll in ring rolling

Image
The linear velocity is proportional to the rotation radius and rotation speed.The linear speed of the main roll is obtained by multiplying the radius of the main roll by the rotational speed of the main roll. V=r × ω There are a motor, gear box and main roll in the main roll assembly. The main roll assembly has a main motor, gear box and main roll. In general, the main speed displayed on the ring-mill program screen is the rotation speed of the main motor.  The main roll assembly has a main motor, gear box and main roll. In general, the main speed displayed on the ring-mill program screen is the rotation speed of the main motor. The rotation speed of the main roll( ω M ) is calculated by the rotation speed of the motor( ω m ) and the reduction ratio of the gearbox(R). ω M = ω m ×R Therefore, the linear velocity of the main roll(V) is, V=R x  ω M  ( R : reduction ratio of the main gear box,   ω M  : rotation speed of the main motor) L...
