Edge drop control performance and influence factor analysis of a UCMW cold mill

A special integral simulation model for lastic deformation of rolls and the three-dimensional a UCMW cold roiling mill was introduced based on the eplastic deformation of strips. The strip center crown and edge drop control performance of work roll bending, intermediate roll bending, work roll shifting and intermediate roll shifting were compared and analyzed through the simulation model. The influences of strip thickness, forward and backward tension, reduction ratio and resistance to deformation on the edge drop were investigated in detail. The results indicate that the strip center crown control ability of work roll bending and the edge drop control ability of work roll shifting are the strongest. The effects of all the factors on the edge drop are more than those on the center crown. It is shown that the edge of a strip is more sensitive to rolling conditions.
