引言热浸镀锌后剩余锌的带出是受工件的重力、温度、提出速度和取向控制的。带出不畅就会导致锌聚积在工件的边角上，跨过微小的孔槽，还会形成锌滴和毛刺。工件在装运之前要根据这些问题的严重程度和客户的要求进行特别清理。我们已经开发出一种带出能得到改善的锌铋合金... Introduction Zinc left after hot dip galvanizing is subject to the workpiece gravity, temperature, speed and orientation control. Out of the poor will lead to zinc accumulation in the corner of the workpiece, across the tiny slot, but also the formation of zinc droplets and burrs. Workpieces should be specially cleaned according to the severity of these problems and customer requirements prior to shipment. We have developed a zinc-bismuth alloy that brings out improvements ...
