<p><P>PROBLEM TO BE SOLVED: To provide a cold-rolling equipment with which the effect of yield improvement and the reduction of manufacturing cost are attained by cutting down trimming allowance and decreasing a width margin by contriving the extension of width control capacity in a cold-rolling process. <P>SOLUTION: A tension leveler 5 which is respectively provided with an inlet-side bridle roll 20 having tension control means 26, 48 on the inlet side of a leveling unit 5 having penetration amount control means 15, 48 and an outlet-side bridle roll 30 having tension control means 36, 48 on the outlet side is provided between pickling equipment 1 and a cold tandem rolling mill 50. As necessary, by measuring the width and the sheet passing speed and controlling the elongation percentage, the width is controlled. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
