中国热镀锌技术及发展动向

CHINESE HOT ZINC PLATING AND ITS DEVELOPMENT

介绍了中国热镀锌的现状及技术进展。指出汽车用板、热轧带钢热镀锌和高耐蚀性镀锌板的开发是带钢镀锌的主要进展;Galfan合金镀、厚镀层钢丝的开发和锌锅内加热技术是金属制品行业热镀锌的主要进展;活性钢热镀锌和锌锅大型化技术是结构钢热镀锌的主要技术进展。认为建筑用镀锌钢材是热镀锌行业新的经济增长点,分析了国内热镀锌钢管的市场前景,强调解决热镀锌的三废治理是当务之急。

The present situation and technical development of Chinese hot zinc plating are introduced. It is pointed out that car-using plate, hot-rolling strip hot zinc plating and high corrosion-resisting zinc-plated plate are the main development direction of strip steel zinc-plating, Galfan alloy-plating, thick coat wire and heating in zinc bath are the one of metal-manufactured-products industry, activated steel plating and making zinc bath of large-scale are the one of structured steel. It is considered that building using zinc-plating steels is the new economic increase point of hot zinc plating industry. The market prospect of national hot-zinc-plated pipe is analyzed. It is emphasized that to resolve the problem of the three wastes is the most urgent matter.
