The "free specification rolling" range of the tangential pass is from 9% of the final diameter to a maximum of 3mm. This range is obviously larger than the adjustment possibilities of the 2-roll system in one pass. It brings the advantages of fewer passes, fewer frame changes, and smaller storage capacity of rollers and guides. 5 Conclusion

The three rolls are arranged along the pass line at 120 degrees, and the rolling force is applied to the rolled piece by the three rolls at the same time, so that a uniform compressive stress area perpendicular to the rolling direction is formed in the center of the rolled piece, thereby obtaining better mechanical properties.

During the rolling process, roll wear is inevitable, and the wear of the roll leads to changes in pass size, as shown in Figure 3. At the same time, the surface roughness of the roll also changes with the wear of the roll, which in turn affects the extension and width of the rolled piece, thereby affecting the dimensional accuracy of the ...
