酸浸是用酸除去钢铁表面轧制铁鳞的一种工艺。酸浸除鳞的机理是基于化学氧化、还原、氢发生等电化学反应以及物理剥离作用。在酸浸除鳞过程中,不可避免要产生酸对金属基体的腐蚀,这不但造成钢材的无谓损失,也造成酸的大量浪费。据资料报道,酸浸时用和不用缓蚀剂,酸量的消耗相差20倍。加缓蚀剂不仅能有效防止酸的多余消耗和钢材的腐蚀溶解,还能提高钢材的表面加
Acid leaching is the use of acid to remove iron and steel surface rolling scale of a process. Acid leaching scale mechanism is based on chemical oxidation, reduction, hydrogen generation and other electrochemical reactions and physical stripping. In the acid leaching process, inevitably produce acid corrosion of the metal matrix, which not only causes deadweight loss of steel, but also caused a lot of waste of acid. According to data reports, acid leaching with and without corrosion inhibitors, acid consumption of 20 times the difference. Plus corrosion inhibitor can not only prevent the excessive consumption of acid and corrosion of steel dissolved, but also increase the surface of steel
