Abstract
PURPOSE: To surely prevent the generation of the transverse bend, by detecting the transverse offset of the rolled material after running out of the rolling stand, and by operating the optimum draft correction value for one side using the analytic model.
CONSTITUTION: At the point of time that the forefront of the rolled material 10 runs out of the rolling roll 12 and arrives at the second forefront position detector 24, the first forefront position detector 22 and the second forefront position detector 24 simultaneously measure the forefront position of the rolled material 10 corresponding to the transverse offset positions X1, X2, of the rolled material 10 at each forefront position; then, the offset value operator 26 operates the difference between above offset positions, and obtains the transverse offset value ΔX. The one side draft correction value operator 30 operates the one side draft correction value ΔS depending on rolling information consisting of the transverse offset value ΔX obtained as the output of the offset value operator 26 and the output of the setter 28. This one side draft correction value ΔS is inputted to the draft position controller 20W which then corrects the draft position. Hereby, the transverse bend of the rolled material 10 is straightened.
