Production method of pickling-free 82B wire rod

The invention discloses a production method of a pickling-free 82B wire rod, which is used for producing an 82B wire rod product of which the oxide scale on the surface is easy to peel off and the base body is smooth and clean after peeling off by controlling the microstructure, thickness and phase structure of the oxide scale on the surface of the 82B wire rod in a hot rolling process. According to the 82B wire rod product, the processes of acid pickling and phosphating can be omitted in the downstream drawing process, the oxide scale can be cleaned up through a simple mechanical shelling process, and the drawing requirement is met. According to the technology, the acid consumption is reduced, the pollution is reduced, and the cost is saved. Belongs to the field of environment-friendly consumption-reducing production. 本发明公开了一种免酸洗82B盘条的生产方法，通过控制热轧制过程中82B盘条表面的氧化铁皮的微观组织、厚度及相结构，生产出一种表面氧化铁皮易于剥落且剥落后基体光洁的82B盘条产品。这种82B盘条产品在下游拉拔工序时可省去酸洗、磷化工序，采用简单机械剥壳工艺便能将氧化铁皮清除干净，满足拉拔需求。本技术减少酸耗、降低污染的同时还能节约成本。属于环保降耗生产领域。
