我厂是为自行车生产提供冷轧带钢及焊接钢管的专业厂,在冷轧带钢及管坯带钢的生产过程中,长期存在着酸雾污染的问题。这是因为带钢在轧制前需要经过酸洗处理以去除表面的氧化铁皮等各种杂质,历来采用无机强酸如硫酸,盐酸等等。为了提高酸洗速度,还常往酸液中通入高温蒸汽来提高酸 I plant for the production of bicycles to provide cold-rolled strip and welded steel pipe professional factory in the cold-rolled strip and tube strip production process, the long-term existence of acid mist pollution problems. This is because the strip need to be pickled before rolling to remove the surface of the oxide scale and other impurities, has always been using inorganic acids such as sulfuric acid, hydrochloric acid and so on. In order to improve the pickling speed, it is also often to acid into the high-temperature steam to improve the acid
