成都无缝钢管厂金堂分厂是一个大型冷轧钢厂。为了增强无缝钢管的表面韧性,便于钢管的冷却变形和加工,在加工前需对钢管进行酸洗除锈。其方法是将无缝钢管吊入装有硫酸溶液的酸洗槽内浸泡,此时逸出的大量酸雾由车间侧面窗户自然排出,由于通风
Chengdu Seamless Steel Tube Factory Jintang branch is a large cold-rolled steel mills. In order to enhance the surface toughness of seamless steel pipe, easy to steel pipe deformation and cooling, before processing steel pipe rust pickling. The method is to hang the seamless steel pipe into a pickling tank filled with a sulfuric acid solution, and a large amount of acid mist escaping from the side window of the workshop is discharged naturally. Due to ventilation
