摘要： Set values of a gauge-alteration-in-rolling amount after the next (i+1)-th stand and subsequent stands are modified, using the rolling results obtained when a leading end of a succeeding material passes through the i-th stand and the gauge results of the leading end portion of the succeeding material detected by the i-th stand outlet side gauge detector. The gauge results of the leading end of the succeeding material on the i-th stand outlet side is tracked up to the (i+1)-th stand, to thereby control the rolling speed of the i-th stand so as to make constant a mass-flow from the leading end of the succeeding material on the (i+1)-th stand inlet side. Thereby, the reverse off gauge caused at the succeeding stand, by turning on the AGC of the preceding stand, can be prevented and the gauge can be controlled to a desired value from the coil leading end portion.
