Effect of micro-plasto-hydrodynamic lubrication on strip surface in steel cold rolling

Abstract. This study employs numerical calculations based on the micro-plasto-hydrodynamic lubrication (MPHDL) theory to analyze the evolution of oil pits during the stainless-steel cold rolling process. The model is enhanced by incorporating lubricant temperature variations caused by its contact with the heated roll and strip, as well as variations in pit slope. The findings show the significant impact and relevance of considering these additional parameters in assessing the performance of the MPHDL mechanism. Notably, the model demonstrates good agreement with experimental measurements conducted on a Stainless-Steel grade undergoing multiple passes.
