摘　　要：锌液有效Al含量是影响热镀锌产品镀层表面和性能的关键参数,针对其精确和稳定控制难度大的问题,研究了不同生产条件下锌液Al含量消耗规律和不同锌锭(Al含量为0.4 wt.%、0.8 wt.%和4.2 wt.%)加入后对Al含量的影响。结果表明:通过常规锌锭Al含量的合理设计,单独添加时可保证Al含量最低达到目标区域下限附近,然后根据条件采用不同调Al锌锭进行优化调节,可以达到锌液有效Al含量精确和稳定控制目标。The effective Al content of molten zinc is a key parameter that affects the surface and properties of hot-dip galvanized products.Aiming at the difficulty of accurate and stable control of the effective Al content,the consumption law of Al content in molten zinc under different production conditions and the influence of different zinc ingots(Al content was 0.4 wt.%,0.8 wt.%and 4.2 wt.%)on Al content were studied.The results showed that through the reasonable design of the Al content of conventional zinc ingots,the Al content could be guaranteed to reach near the lower limit of the target area when it was added alone,and then the effective Al content of molten zinc could be controlled accurately and stably by using different Al adjusting zinc ingots according to the conditions.
