Description

Technical Field

[0001] The utility model relates to the technical field of conductive rollers, in particular to a 316L stainless steel conductive roller with a roller surface sprayed with Hastelloy alloy. Background Art

[0002] Conductive rollers are key components in continuous nickel electroplating production lines, used to convey steel strips and conduct strong cathodic current during the electroplating process.

[0003] The existing patent document with announcement number CN214400766U discloses a stainless steel conductive roller. By setting a conductive improvement layer on the outer wall of the conductive roller body, the internal resistance of the conductive roller can be greatly reduced and the conductivity can be improved; by setting an acid-resistant layer on the outer wall of the conductive improvement layer, the conductive roller can be effectively prevented from being corroded by electrolyte solvents; by setting a hardness enhancement layer, the surface wear resistance can be enhanced; by setting a cooling mechanism, the temperature of the conductive roller can be reduced by conveying cooling water, thereby solving the problem of heat generated by conductive current; in summary, the beneficial effects of facilitating heat dissipation, enhancing conductivity, enhancing acid corrosion resistance and improving wear resistance are achieved.

[0004] Although the above-mentioned stainless steel conductive roller can solve the corresponding technical problems, its cooling method is to pass cooling water into the conductive roller body through a connecting rod at one end, and the cooling water flows out from the connecting rod at the other end, so that the cooling water dissipates heat when the conductive roller is energized. However, during the cooling process, the cooling water directly flows into and out of the conductive roller body, which not only shortens the flow time in the conductive roller body, but also reduces the cooling efficiency. Therefore, we propose a 316L stainless steel conductive roller with Hastelloy alloy sprayed on the roller surface. Utility Model Content

[0018] The utility model has at least the following beneficial effects:

[0019] The beneficial effect of the utility model of the present application is that by adding a spoiler component between the conductive roller body and the cooling component, the cooling water inside the conductive roller body can play a spoiler role.
