The invention relates to a method for producing an extreme-thin ultra-deep punching cold-rolled sheet by a vertical continuous annealing furnace. The extreme-thin ultra-deep punching cold-rolled sheet comprises the following raw materials of not more than 0.008 of C, 0.08-0.20 of Mn, and not more than 0.020 of P and S; and the cold rolling compression ratio is 80-86.7 percent, the real annealing temperature is 60-90 DEG C higher than a recrystallization temperature of IF steel, the annealing temperature is 140-220m/min, and the smooth percentage elongation is controlled to be 0.4-0.6 percent.Detected by experiments, the finished product strip steel has yield strength of 159MPa, tensile strength of 316MPa, percentage elongation after fracture of 38 percent, N value of 0.21 at 90 degrees and R value of 2.16 at 90 degrees, which reach the specified standard requirements. Meanwhile, phenomena of scratching, roll marking and the like do not occur in the production process, the finished product strip steel has better surface quality and fully meets the user demands; and the method is simple and easy, is convenient for operation, and realizes that the extreme-thin ultra-deep punching cold-rolled strip steel is stably produced by adopting a large vertical continuous annealing furnace under the condition of no increase of processes and equipment.
