Duplex stainless steel strip annealing and pickling method and steel strip produced by method

The invention provides a duplex stainless steel strip annealing and pickling method and a steel strip produced by the method, and belongs to the field of metal pressure processing. The method includesthe steps of pretreatment, continuous annealing, shot blasting treatment, scale breaking treatment, pickling treatment, coiling, rolling, secondary annealing, secondary pickling and secondary coiling. The method is high in acid pickling efficiency and low in production cost, continuous production of a thermal annealing acid pickling plate strip can be achieved, and the production period is shortened. 本发明提供了一种双相不锈钢带退火酸洗方法及利用该方法生产的钢带，属于金属压力加工领域，该方法包括以下步骤：预处理、连续退火、抛丸处理、破鳞处理、酸洗处理、卷取、轧制、二次退火、二次酸洗和二次卷取。该方法酸洗效率高，生产成本低，可实现热退火酸洗板带连续生产，缩短了生产周期。
