摘　　要：锡层厚度均匀性控制技术对镀锡板的耐蚀性、阳极条纹、白边缺陷等均有明显影响,在镀锡板生产工艺中具有重要意义。针对首钢京唐可溶性阳极高速电镀锡机组,从宏观分散能力和微观分散能力两个方面进行实验研究。结果表明:通过使用“阳极错位调节法”,同时调节电镀电流密度为25~27 A/dm^(2)、锡离子浓度调节至16~18 g/L,在实现ATC值和孔隙率显著降低的同时,锡层横向厚度极差降低至10%以内,锡层均匀性得到显著提高。The control technology of thickness uniformity of tin layer is very important in the production process of tin plate,which has obvious influence on corrosion resistance,anode stripe and bright edge defect of tin plate.In this paper,Shougang's soluble anode high speed tin plating unit was studied from two aspects of macroscopic and microscopic dispersion ability.The results show that by using the"anode displacement adjustment method",adjusting the electroplating current density to 25-27 A/dm^(2) and tin ion concentration to 16-18 g/L,the ATC value and porosity are significantly reduced,while the tin thickness range is reduced to less than 10%,and the tin layer uniformity is significantly improved.
