<p>PURPOSE:To provide the control method capable of surely preventing the occurrence of camber in a hot rolling. CONSTITUTION:The temperature difference in the transverse direction of a material 1 is measured at the inlet side of a rolling mill, difference load in the transverse direction generated by the temperature difference is presumed, the outlet side wedge quantity predicted from the presumed difference load is found, the roll wedge quantity for canceling the wedge quantity is obtained and the balance force difference of work rolls 2 is set so that the roll wedge quantity is realized. Consequently, the occurrence of camber can be controlled predictively by adjusting the movement of the draft center.</p> |
