The invention discloses a method for continuous annealing and pickling of a stainless steel band. The method mainly comprises the following steps that uncoiling is conducted; alkali wash is conducted, specifically, the temperature of alkali wash water is 42 DEG C-50 DEG C, and the PH value of the alkali wash water is 8.5-9.2; annealing is conducted, specifically, the temperature of an annealing furnace is set into eight sections, the temperature from an inlet to an outlet is sequentially and gradually increased from 820 DEG C to 960 DEG C, and the excessive oxygen concentration is sequentially increased from 3% to 5%; electrolysis is conducted, specifically, a electrolytic pickling solution comprises a neutral salt solution, silicic acid, nitric acid and one or more surfactant solutions; pickling is conducted, specifically, the pickling concentration is 150-170 g/L, the metal ion concentration is 50-60 g/L, and the temperature is 65-70 DEG C; first mixed pickling is conducted, specifically, the concentration of the nitric acid is 120-140 g/L, and the concentration of hydrofluoric acid is 35-50 g/L; second mixed pickling is conducted, specifically, the concentration of nitric acid is 130-140 g/L, and the concentration of hydrofluoric acid is 40-50 g/L; and wash cooling is conducted. By adoption of the method, iron oxides in an oxide skin can be effectively removed, the pickling time is greatly shortened, and the pickling effect is good.
