Computer simulation of the roll contact pressure characteristic for 6-high CVC wide strip mill

The computer simulation of the roll contact pressure characteristic for 1850 mm 6-high CVC wide strip mill is 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 researched results indicate that the axial shift of CVC intermediate roll, the bending of work roll and the bending of intermediate roll have outstanding influence to the transverse distribution of rolling pressure, and clear influence to the transverse distributions of the pressure betweens rolls. On various conditions, the transverse distributions of the pressures between rolls are always `S' form.
