Jun 19, 2017· 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 problem is related to Finishing Stand. In hot rolling mill during the metal rolling at finishing mill (4Hi mill Reversible), work roll pair come out due to the axial crossing of work rolls and due to which uneven thickness of metal, strip breakage, bending of locking plate, metal shifting and equipment breakdown occurs.
