The invention belongs to the technical field of hot rolling processes, and discloses a method for increasing the hot rolling speed of a ferrite. The method comprises the following steps of rolling by adopting a low-tempreature heating method, controlling the tapping temperature to be 1,080-1,180 DEG C, and controlling the time in the furnace to be 170-250 min; conducting rough rolling by adopting a 3+5 rolling mode, forming 3 passes through rolling of a rough mill frame R1, and forming 5 passes through rolling of a rough mill frame R2; executing all-pass scale removal operations by a rough mill R1 and a rough mill R2, putting the rough mill R1 in the first pass and the third pass, and putting the rough mill R2 in the first pass, the second pass, the third pass, the fourth pass and the fifth pass; synchronously conducting steel placing and air cooling in front of a width gauge and the rough mill R1 and on the rough mill R2; and reducing the pass rolling speed of the rough mill R2, and controlling the pass rolling speed of the rough mill R2to be 2.0-2.5 m / s.
