- 受制于短带材的长度特点及其对镀层均匀性的要求，没有合适形状的挂具。本文通过设计一种圆柱体形挂具，将挂具与带材接触的部分凹陷，用其固定内侧阳极来控制阳极板与带材的相对位置，依靠带材侧面与挂具的两个接触点导电；还对挂具进行了绝缘处理、采用辅助阴极使电流分布更均匀。结果表明，改进挂具的凹陷设计、采用辅助阴极改善了镀层厚度分布的均匀度，镀层厚度分布的标准差由 1.8 μ m 变为 0.4 μ m ，实现了不锈钢短带材卷绕后的均匀电镀。
- Abstract:
- ： There is no hanger with suitable shape for the thin characteristics of short strip in order to meet the requirements of thickness uniformity of the coating. In this paper ， a cylindrical hanger is designed ， whose part of contacting with the strip recessed ， and the inner anode is fixed with it to determine the relative position of the anode plate and the strip. It can electrify by the two contact points between the side of the strip and the hanger ； in order to make the current distribution more uniform ， the hanger was insulated and auxiliary cathode was used. The treatments are helpful in homogeneity of the coating thickness distribution. The standard deviation of the coating thickness distribution is decreased from 1.8 μ m to 0.4 μ m ， which means the short 316L strip was plated uniformly .
