DESIGN AND ANALYSIS OF AXIAL CROSSING OF WORK ROLLS IN ROLLING MILL WORK ROLL ASSEMBLY: A REVIEW

Rolling Mill is one of the machine for rolling steel or other metal into sheets. For reliable and efficient working of rolling mill it is necessary that all the components used in rolling mill should work properly without fail. Work roll assembly is very important part of the rolling mill. It has been observed that In hot rolling mill during the metal rolling at finishing mill (4-Hi 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. After the Study it has been observed that wear of the work roll liner is one of the reasons for the axial crossing of the work rolls. By modeling in Pro-E software and analysis in ANSYS13.0 (workbench) software it has observed that the wear is there in the liner. Through this analysis I found the stresses developed on liner under working process. Axial crossing of work rolls is the major Problem Facing by Steel rolling companies and due to this crossing there will be defects in the Products of the rolling mill. By conducting the detailed analysis it has been found that if we change the material 1045 steel to improved material or induction hardening of the liner then there will be less wear in the liner so that we can reduce this problem.
