<p>PURPOSE:A good configuration is provided to a rolled material by controlling tension distributions so as to be of a desired pattern both at backward of a first stand and at forward of a last stand. CONSTITUTION:A configuration detector 41 finds a tension distribution between a payoff real and a first stand, compares it to a disired pattern 43 and calculates a difference therebetween. Based on this, an amount of reduction 44 to be corrected at the first stand is calculated, and an adequate roll bending force 45 is calculated and controlled. Meanwhile, another configuration detector 42 finds a tension distribution between a tension reel and a last stand, compares it to a desired pattern 53 and calculates a difference therebetween. Based on this, an amount of reduction 54 to be corrected at the last stand is calculated, and an adequate bending force 55 is calculated and controlled. Thus, the process assures high-precision control.</p> |
