摘要
介绍了中粤马口铁工业有限公司采用弗罗斯坦法生产电镀锡薄钢板的镀后软溶、钝化、涂油的三个工序,指出电镀锡薄钢板表面的“木纹”缺陷与镀前的酸洗状况和加热方式有关,建议钢带适度酸洗,减少钢板表面氧化膜的形成;并将现用的电阻加热软溶改为感应加热或联合加热软溶的方式;钝化液的pH最好在4～5.5之间。
In this paper, three steps such as reflowing, passivation and greasing for post-
plating treatment of tinplate, which is made by Ferrostan method in Zhongshan Zhongyue
Tinplate Industrial Co., Ltd., are introduced. It is concluded that the wood grain defect of
tinplate surface relates to the acid washing and heating ways before plating. It is suggested
that the acid washing of steel strips should be appropriate so as to reduce the formation of
oxide film on the surface of tinplate. The reflowing by resistance heating, that is in use
now, should be replaced with the reflowing by industrical heating or combined heating. The
passivating solution pH should be 4～5. 5.
