Abstract

Presented is a new logarithmic spiral roll profile for 2-high hot rolling,and successfully establishing the logarithmic spiral roll profile equation.The inherent benefits over traditional sine curve roll profile include control of rolling force and optimization of strip profile.Comparison of rolling force and strip profile produced by logarithmic spiral rollers with that produced using traditional sine curve rollers through three-dimensional finite element simulation also verifies the new roll profile is more prominent in reducing rolling force and optimizing strip profile than traditional sine curve roll profile.

Keywords
