Abstract

A hydrodynamic lubrication theory is developed for high-speed strip rolling. The operating conditions include: non-dimensional roll speed, F, strip reduction ratio, RE, and front and/or back tensions. The pressure gradient in the work zone is taken into account in the analysis. The 'moving' boundary conditions for temperature distribution are used in three zones. The effects of the operating conditions on hydrodynamic pressure and temperature, film thickness, forward slip, roll load and torque and system instability are described in detail and compared with previously published data.
