PURPOSE:To stabilize conveying of a strip by controlling tension applying to the rapidly cooled strip in the specific range at the time of conveying the rapidly cooled strip to pinch rolls composing of brushing roll and solid roll. CONSTITUTION:The pinch rolls composing of the brushing roll 1a and solid roll 1b are arranged, and an arm 3 is arranged to a rotating shaft 2 of the brushing roll 1a and a cylinder 4 for rolling reduction is fitted at one end thereof and a load cell 6b for measuring rolling reduction force. The brushing roll 1a is pushed to the solid roll 1b through the cylinder 4 to give the rapidly cooled strip 3 passing through between both rolls the tension. Then, by adjusting pushing rate and rolling reduction force of the brushing roll 1a or either peripheral velocity ratio of the pinch roll 1 or the cooling roll, while controlling the tension of the strip 5 in the range of 2-8kgf, the conveying is executed. By correction for snaking of the roll 1a and suitable control for the tension, the conveying of the strip is stabilized. |
