ABSTRACT:
A multi-stand rolling mill is operated so that strip of suitable shape and metallurgical properties is produced at a faster speed than possible heretofore by threading the mill at a relatively slow speed and adjusting the rolling loads on the stands to give the required output gauge and rolling temperature at the last stand, thereafter the mill is accelerated and curtains of liquid coolant are applied to the workpiece at one or more interstand locations to ensure that the rolling loads remain substantially the same as when threading and the rolling temperature of the last stand remains substantially constant.
