本文叙述了热镀锌史的发展概况,以及近年来热镀锌钢管在国民经济中所处的地位,我国热镀锌钢管的生产历史及技术水平,与国际上的热镀锌技术和工艺相比存在的差距等。 文中建议尽快地研究并采用微氧化还原法、镀后钝化处理等新工艺,并指出:不论新建或扩建热镀锌钢管工厂(车间)应尽量采用没有三废的工艺方法。 This article describes the development history of hot galvanized history, as well as in recent years, hot dip galvanized steel pipe in the national economy, the status of China’s hot galvanized steel pipe production history and technical level, and the international hot-dip galvanizing technology and process phase Than the existence of the gap. The paper suggests that as soon as possible to study and use of micro-oxidation reduction, post-plating passivation and other new processes, and pointed out: Whether new or expanded hot-dip galvanized steel pipe plant (workshop) should try not to waste process.
