Abstract
The rolling mill comprises a pair of work rolls for rolling a plate material in the thickness direction, a guide for guiding the leading end of the plate material between the work rolls, and a rolling oil supply member for supplying rolling oil between the work rolls through a rolling oil passage formed within the guide. The rolling mill further comprises a temperature adjusted oil passage formed within the guide separately from the rolling oil passage, and a temperature adjusted oil supply member for applying temperature adjusted oil having a different temperature from the rolling oil to the work rolls through the temperature adjusted oil passage so as to control the crown rate of the work rolls, improving the controllability of the crown rate of the work roll.
