Abstract:
Material rolled in heavy plate mills and roughing stands often bends upwards or
downwards. This phenomenon can lead to poor shape, profile and quality of the product, as well as
lower productivity. This paper focuses on the well- known bending due to the related asymmetrical
entrance angle between the rolling stock and work roll which can easily cause asymmetrical shape
factor in deformation zone. A model for calculating curvature quickly is deduced based on the
condition of asymmetrical entrance angle. Results show that the front end bending can occur easily
due to the asymmetrical entrance angle. Moreover, the bending inclination of large reduction, large
radius of roll and thin rolling stock is greater than that of the reverse; the bending inclination of the
entrance thickness of rolling stock is greater than that of the reduction, and the bending inclination of
the reduction is greater than that of the radius of roll.
