不溶性阳极镀锡时两种镀锡量不均情况的探讨

Discussion on two situations of non-uniform tin coating weight when tinning with insoluble anode

焊接质量差而造成的板型不良,或原本基板头尾板型较差,均可导致降速焊接段镀锡量偏低。而不溶性阳极板安装不当易导致全宽方向镀锡量不均匀。前一种情况可根据带钢运行速率对电镀电流进行补偿,后一种情况则建议每次停机维修时检查阳极板的安装情况。

The unevenness of black plate itself or caused by poor welding may lead to insufficient tin coating weight during welding section with reduced running rate of steel strip. The improper installation of insoluble anodes may result in non-uniformity of tin coating weight along the width direction. For the first situation, compensation of tinning current is necessary according to the running rate of steel strip. For the second one, inspection of the installation of anodes during each shutdown maintenance is recommended.
