摘　　要：在连续热镀铝锌机组,因锌锅中锌液的铝含量较高,锌液黏度低,当带钢焊缝区域通过锌锅气刀后,会产生气刀条纹。介绍了焊缝区域过锌锅气刀后,带钢表面气刀条纹产生的原因,并通过计算优化了焊机冲孔冲头尺寸,减少了焊缝区域过气刀后气刀条纹产生的概率。In continuous hot aluminum-zinc plating line,due to the high aluminum content of zinc liquid in and low viscosity of zinc liquid,the air knife streaks appear when the weld of the steel pass through zinc pot.This paper introduces the causes of the air knife streaks of the strip surface through the welding,and optimizes the size of the punch of the welder through calculation,thus reducing the probability of air knife streaks when the welding go through the air knife.
