摘　　要：钢板单面镀锌钝化产品是宝钢生产的一类高附加值产品,主要应用于油箱外板。在开发钢板镀锌钝化产品过程中发现,在钢板的未涂敷面出现一种黄斑缺陷,黄斑形状及大小均不规则。为了解决黄斑缺陷问题,针对钢板单面镀锌钝化产品的生产工艺进行实验室模拟,对生产工艺中机组速度、烘干温度等工艺参数与黄斑产生的相关性进行分析,找出黄斑产生原因。One-sided electro-galvanizing passivation sheets are value added products of BAO-STEEL,which are mainly applied to oil tank exteriors.During development process for the products,yellow spot defect was found on non-coated surface,which was irregular both in shape and size.Aming at study on the cause of this defect,on-line process for the one-sided electro-galvanizing passivation sheets were simulated in lab,related processing parameters such as line speed,drying time,etc.were investigated,thus,the possible causes were found.
