The traditional measuring method is that during maintenance, a lower working roll of a final stand is independently installed, then a lower guide plate is moved into a normal steel rolling position, a roller way is cooled to normal temperature by fire water, then a person creeps along a finish rolling outlet roller way and drills into a gap between the upper guide plate and the lower guide plate, and the height difference between the lower guide plate and the roll surface of a stand roll is roughly measured by a caliper.
