近年来,在缩短带钢酸洗时间,抑制酸雾和减少铁损方面,人们不断地探索新的方法。如日本采用了带钢经四辊轧机冷加工(压下率0.5～5%)后再进入装有破鳞辊的酸洗槽的新酸洗法,大大缩短了酸洗时间。在抑制酸雾方面,如鞍山冷轧带钢厂和上钢四厂的窄带酸洗线采用了超 In recent years, new methods have been continually explored in terms of reducing strip pickling time, suppressing acid mist and reducing iron loss. For example, Japan adopted a new pickling method with cold rolling (rolling rate of 0.5 to 5%) of a strip mill through a four-roll mill and then into a pickling tank equipped with a broken scale roll, which greatly shortened the pickling time. In the inhibition of acid mist, such as Anshan cold-rolled steel and steel plant on the narrow-band pickling line used super
