Steel bar annealing process and shelling equipment for same

The invention relates to a reinforcing steel bar annealing process which comprises the following steps: step 1, shelling: a reinforcing steel bar is deformed and shelled by adopting shelling equipment; 2, acid pickling is conducted, specifically, the shell-removed reinforcing steel bars are subjected to acid pickling; 3, phosphorization is conducted, specifically, the steel bars subjected to acid pickling are subjected to phosphorization; 4, annealing is conducted, specifically, the phosphorized reinforcing steel bars are annealed; and 5, wire drawing and rolling, wherein the annealed steel bars are subjected to wire drawing and rolling. The method has the effects of reducing the use of an acid solution, saving resources and protecting the environment. 本发明涉及一种钢筋退火工艺，包括，其包括如下步骤：步骤1：去壳，采用去壳设备使钢筋形变去壳；步骤2：酸洗，对去壳后的钢筋进行酸洗；步骤3：磷化，对酸洗后的钢筋进行磷化；步骤4：退火，对磷化后的钢筋进行退火；步骤5：拉丝收卷，对退火完成后的钢筋进行拉丝收卷。本申请具有减少酸溶液的使用，节约资源保护环境的效果。
