To provide a mill pacing control method for a hot rolling line, capable of improving production efficiency of the hot rolling line.

The mill pacing control method for the hot rolling line includes: adding, as a tolerance value for safety, a value using a statistic value obtained by result-analyzing an error of a result of a time required for conveyance of a rolling object material in a certain section on the hot rolling line or a result of an arrival time of the leading end or trailing end of the rolling object material to a certain point on the hot rolling line relative to prediction of the time required for conveyance of the rolling object material or prediction of the arrival time of the leading end or trailing end of the rolling object material; selecting a time at which extraction from a heating furnace of the hot rolling line is the latest when comparing those to which the tolerance value is added with respect to all facilities on the hot rolling line; and extracting the subsequent rolling object material from the heating furnace of the hot rolling line at that time. The tolerance value is determined using the central value and kurtosis of the result-analyzed statistic value.
