The 9th step: annealing in process for the third time: semi-finished product striped stainless steel band is entered annealing furnace with 9.5～1.0 Mi ∕ minute speed, temperature in the annealing furnace is: 1030～1060 ℃, be filled with simultaneously protective gas, be divided into six zones and one section preheating section in the annealing furnace;
Temperature is controlled at 1000～1050 ℃ in the first area; Temperature is controlled at 1000～1050 ℃ in the second area stove; Temperature is controlled at 1080～1090 ℃ in the 3rd zone furnace; Temperature is controlled at 1080～1090 ℃ in the 4th zone furnace; Temperature is controlled at 1080～1090 ℃ in the 5th zone furnace; Come out of the stove when temperature is controlled at 1050～1060 ℃ in the 6th zone furnace and enter cooling section and be cooled to finished product striped stainless steel band; The temperature of described cooling section remains on 40～60 ℃;
The tenth step: cutting, packing, warehouse-in.
2. the production method of a kind of striped stainless steel band according to claim 1 is characterized in that: described first, second and third time annealing in process protective gas adopts the ammonia heating to resolve into 75% hydrogen and 25% nitrogen: the annealing furnace internal pressure is at 0.3～0.5MP.
3. the production method of a kind of striped stainless steel band according to claim 1 is characterized in that: the thickness deviation of the semi-finished product stainless steel band that described the second rolling process is rolling is ± 0.02mm.
4. the production method of a kind of striped stainless steel band according to claim 1 is characterized in that: the rolling semi-finished product striped stainless steel band thickness deviation of described the 3rd rolling process is ± 0.01mm.
