abstract

During the process of set up and disassembly and usage period, the sleeve of oil film bearing in the backup roll of some 1580PC hot strip mill has been dramatically damaged, which results in production accidents and decreases the service life of bearing. Aimed at such puzzles, theoretical research has been quantitatively analyzed by BEM with 3D elastic-plastic contact, variable laws of stress and strain under different hydroform pressures and axial thrust forces during the setup and disassembly process of sleeve have been drawn, the reasons that result in sleeve failure have been analyzed as well. Finally, Detailed experiments have been made on the two sample mills, which have been manufactured for research and analysis.
