1 前言 酸洗是冶金机械行业去除金属表面杂质,提高产品质量的一种有效方法。带钢在冷轧前进行酸洗,可以清除表面的氧化层,提高冷轧的光洁度。带钢的酸洗,大多采用连续酸洗形式。主要由开卷机、液压剪、送料机、储料槽、酸洗槽及清洗槽组成。在酸洗过程中,为了提高酸洗的质量,加速酸洗时的化学反应速度,通常用压缩空气或高温蒸汽对酸液进行搅拌和加温,因而产生大量的酸雾,弥漫在车间内外,造成极大的危害。
1 Introduction Pickling is the metallurgical machinery industry to remove metal surface impurities, improve product quality, an effective method. Strip pickling before cold rolling, can remove the oxide layer on the surface, improve cold-rolled finish. Strip pickling, mostly in the form of continuous pickling. Mainly by the uncoiler, hydraulic scissors, feeder, storage tank, pickling tank and cleaning tank composition. In the pickling process, in order to improve pickling quality, speed up the chemical reaction speed pickling, usually with compressed air or high temperature steam on the acid stirring and heating, resulting in a large number of acid mist, filled the workshop inside and outside, Cause great harm.
