Tension Differential Equation for Flying Gauge Change of Tandem Cold RollingAbstract: Concept and rolling technique character of flying gauge change for tandem cold rolling are explained. The stretch elongation of strip caused by tension between stands is researched during tandem cold rolling. Deformation differential equation and tension differential equation of flying gauge change are brought up by theoretical derivation according to the strip characters of stress and deformation during flying gauge change of tandem cold rolling. The influencing factors of flying gauge change are analyzed. It is proved that tension differential equation of stable rolling is the special case of tension differential equation of flying gauge change during tandem cold rolling.Key words: tandem cold rolling。 flying gauge change。 tension。 differential equation 。deformation。 speed difference。
