Embodiment Construction

[0014] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings. Such as Figure 3 ~ Figure 6 Shown: the device involved in the present invention includes: column 1, guide rail 2, conductive roller 3, backup roller 4, conductive roller bearing seat 5, backup roller bearing seat 6, backing plate 7, adjustment backing plate 8a, adjustment backing plate 8b. When there is a need for adjustment, you can press the set value ΔS of ΔS 设 , so that (the thickness of the adjustment backing plate 8a-the thickness of the adjustment backing plate 8b)=2ΔS 设 , the center of the back-up roller 4 moves along the opposite direction of the running of the strip steel 9, and the center of the conductive roller 3 is staggered by ΔS 设 . Now the conduction area between conductive roller 3 and strip steel 9 just can increase, and resistance reduces, and between plating tank outlet and conductive roller 3, the drift current in the pl...

Abstract

The invention provides a conduction state adjustment method of the horizontal electroplating bath conducting roller and the band steel. The conduction state adjustment method is characterized in that the adjustment base plates 8a and 8b between the guide slots which are arranged on the two sides of the bearing block of the supporting roller, and the guide way of vertical shaft to drive the centre of the supporting roller to move along the inverse direction of the running direction of band steel and be staggered for delta S with the centre of the conducting roller, thus the conductive area between the conducting roller and the band steel is increased at the time and the resistance is reduced while the drift current in plating solution stored on the upper surface of the band steel between the coating bath outlet and the conducting roller can be reduced so as to reduce or eliminate the zinc-bonding phenomenon of the conducting roller. The beneficial effect of the invention is that the service life of the conducting roller is prolonged, the product quality of the band steel is increased, and the production efficiency is improved.

Description

Technical field: [0001] The invention relates to the technical field of strip steel continuous electroplating, in particular to the adjustment of the conductive state of a horizontal electroplating tank conductive roller and strip steel. Background technique: [0002] For the horizontal electroplating tank on the existing strip steel continuous electrogalvanizing production line, the center of the conductive roll and the center of the back-up roll are all located on the same vertical center line (such as figure 1 , figure 2 shown). When energized for electroplating, since the back-up roll is a rubber-covered roll, the conductive part between the conductive roll and the strip steel is in the shape of a narrow strip. When the center of the conductive roller and the center of the back-up roller are on the same vertical center line, the conductive area is small and the resistance is relatively large. Strong drift current, under the action of drift current, it is easy to plat...
