<p>PURPOSE:To improve shape failure correcting accuracy. CONSTITUTION:A tension reel 2 constituting a winder is arranged on the outlet side of a final stand 1a of a tandem mill 1 composed of plural rolling mills. A sleeve 3 having prescribed resiliency and a thickness not less than 30mm is coaxially installed on the outer periphery of a winding shaft 2a of the tension reel 2. Outlet side tensile force of the final stand 1a in the tandem mill 1 is controlled in 15Kgf/mm<2>, or is controlled so that winding torque of the winder, that is, winding tensile force is set not less than 15Kgf/mm<2>.</p> |
