The final dimensional quality of the rolled product is determined by the rolling stands within the finishing mill. The dimensional accuracy in the final product depends on many factors including the initial stock dimensions, roll pass sequence, temperature, microstructure, roll surface quality, roll and stand stiffness and the stock/roll friction condition.

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

KOCKS sizing mill adjustment is on the main console. Upload important rolling parameters such as the roll gap, speed, reduction ratio, work roll diameter of the roll ring, and motor speed of the rolling specifications in BAMICON. When uploading the program, all rolling mills should be in a stopped state, and KOCKS should be "concentrated".

Fig 5 Analysis 0f roll stand in rail rolling and non-uniform deformation in shape rolling. Computer-aided roll pass design – Shape rolling converts large, normally square sections, into smaller sections of different shapes. The most frequently used breaking-down sequences are box pass, diamond pass, square-diamond-square passes, and square-oval-square passes.

The production of 100 mm grinding balls using rolls with double-threaded pass design and a discretely variable pitch is characterized by increased roll wear, which leads to characteristic surface defects on the balls. A new roll pass was designed, rolls were made, and pilot 100 mm grinding balls were rolled using new double-threaded rolls.
