The invention discloses a method for eliminating a warping defect of a boron-containing low-carbon aluminum killed steel strip. The method is characterized in that after refining of boron-containing low-carbon aluminum killed steel is finished, if B is less than or equal to 0.0015%, molten steel is cast to obtain a slab, and then a first heating procedure is performed; after refining of the boron-containing low-carbon aluminum killed steel is finished, if B is larger than 0.0015% and less than or equal to 0.0030%, the molten steel is cast to obtain a slab, then a second heating procedure is performed, the furnace temperature of the slab entering the second heating procedure is controlled to be 300-600 DEG C, the time of contain in the furnace is 130-180 minutes, and the discharging temperature is controlled to be 1170-1220 DEG C. According to the method, on the basis of steelmaking and hot rolling existing equipment, the boron-containing low-carbon aluminum killed steel hot-rolled strip edge part warping defect is eliminated by controlling the components and the hot rolling process, and the method is simple and easy to implement.
