连续热镀锌锌液铝含量调节方法
摘要：
本发明提供一种连续热镀锌锌液铝含量调节方法，在连续热镀锌工艺过程中，检测锌液中的总Al含量，并执行以下操作：若总Al含量≤0.185％(重量)，则添加主锌锭①；若0.185％(重量)＜总Al含量≤0.190％(重量)，则以重量比为1∶4添加主锌锭①和主锌锭②；若0.190％(重量)＜总Al含量≤0.195％(重量)，则以重量比为1∶8添加主锌锭①和主锌锭②；若0.195％(重量)＜总Al含量＜0.22％(重量)，则添加主锌锭②；若总Al含量≥0.22％(重量)时，则以重量比为1∶4添加纯锌锭和主锌锭②，添加过程中以锌液面不变为基准。
摘要（英）：

The invention provides a continuous hot dip galvanizing zinc liquid aluminium content adjusting method. In the continuous hot dip galvanizing technical process, the total Al content in zinc liquid is detected, and the steps are carried out: if the total Al content is less than or equal to 0.185%(weight), a main zinc ingot (1) metal is added; if the total Al content is more than 0.185%(weight) andless than or equal to 0.190%(weight), the main zinc ingot (1) and a main zinc ingot (2) are added based on the weight ratio of 1:4; if the total Al content is more than 0.190%(weight) and less than or equal to 0.195%(weight), the main zinc ingot (1) and the main zinc ingot (2) are added based on the weight ratio of 1:8; if the total Al content is more than 0.195%(weight) and less than 0.22%(weight), the main zinc ingot (2) is added; if the total Al content is more than or equal to 0.22%(weight), a pure zinc ingot and the main zinc ingot (2) are added based on the weight ratio of 1:4; and in the adding process, the unchanged zinc liquid level is taken as reference.
