Abstract: The analysis and calculation of the roll contact pressure for 900mm HC cold rolled strip mill was carried out by using the strip element method to analyze the three-dimensional plastic deformation of strip and by using the influencing coefficient method to analyze the elastic deformation of rolls. The results indicate that the axial shift of the middle roll of HC mill and the bending of work roll have influence on the transverse distribution of the pressure between rolls.
