Analysis of Contact Pressure between Rolls under Non-symmetrical Roll Bending of UCM Cold Rolling Mill

摘要：

For UCM cold rolling mill, the intermediate roll shifting can enhance the ability of mill for better flatness control, but it will increase the non-uniform distribution of pressure between rolls, as result of a reduced roll life. In order to improve the contact state among rolls in rolling processes and to slow down the roll wear, the distribution of pressure between rolls under different forms of roll bending control has been calculated and analyzed by the influence function method in this paper. For the purpose of obtaining comprehensive information, not only the distributions of pressure between rolls with traditional work roll symmetrical bending and intermediate roll symmetrical bending have been analyzed, but also the distributions of pressure between rolls with non-symmetrical roll bending have been analyzed. All the analyses show that the work roll non-symmetrical bending as well as the intermediate roll non-symmetrical bending can play an important role in the slowing down of roll wear.
