PURPOSE: A multi-control rolling method is provided to implement multi-rolling by identifying the number of slabs for a multiple rolling, and the reset rest reduction rate in real time for a multiple rolling, thereby improving productivity. CONSTITUTION: A multi-control rolling method includes a step of setting the rest reduction rate and the number of slabs, a step of determining whether a rolling time is included in an air cooling waiting time which is set according to the rest reduction rate, a step of resetting the rest reduction rate according to the determination. The air cooling waiting time includes an air cooling waiting time in which an initial slab is rolled first, and an air cooling time in which a final slab is rolled secondly. The air cooling waiting time in which the initial slab is rolled first is set as a first air cooling waiting time, and the air cooling time in which the final slab is rolled secondly is set as a second air cooling waiting time.
