ժҪ In this paper a formula of calculating curvature radius was deduced according to the theory of rolling combining with the characteristic of rolling process; moreover, the simulation of producing process is represented. Simulating results indicate that the curvature radius could be diminished by increasing friction coefficient, friction coefficient ratio, reduction ratio or roller radius, while be augmented by increasing the thickness of plate. Furthermore, increasing the thickness of plate would cause more effects on front end curvature, whereas reducing ratio would do less. It provides theoretic gist to eliminate the front end curvature in plate and sheet rolling industry, and it is important to protect scene controlling equipment and increase forming ratio as well.
