In the above embodiment, the general various processes before the steel wire is plated are collectively called pre-plating treatment, the steel wire is to be plated, no matter which process is to be plated, the lubricating film or the oxide skin on the surface of the steel wire must be removed completely, some processes adopt single electrolytic treatment, some processes adopt ultrasonic treatment, some processes adopt dry and brittle processes, the two processes adopt the best treatment effect and the highest efficiency, the lubricating grease on the surface of the steel wire is treated by alkaline treatment liquid, the phosphating film or the oxide skin on the surface of the steel wire is treated by acidic treatment liquid, the ultrasonic treatment liquid has good treatment effect on the grease and the phosphating film or the oxide skin, the steel wire is cleaned in a hot water tank after the surface treatment, the surface residual treatment liquid is washed, then the steel wire enters a plating assistant tank, the surface of the steel wire is covered with a layer of plating assistant agent and is isolated from air, the steel wire is not oxidized, and finally the steel wire enters a zinc tank for zinc plating, a, the whole galvanizing process is finished.
When the rare earth-containing zinc plating solution is used, the rare earth-containing zinc plating effect can be achieved by a process method of directly adding rare earth (Re, lanthanum mixed rare earth) into the zinc plating solution, the surface smoothness is high, and the cost is low. The galvanized steel wire is measured through an artificial accelerated corrosion test (salt spray test), red rust can be generated within 70 hours, the time of the red rust generation of the steel wire after common galvanization is longer than that of the steel wire after common galvanization, and the time of the red rust generation of the common galvanized steel wire is 40-50 hours.
Specifically, when placing tombarthite in the liquid zinc, the bottom height of sleeve pipe 704 is greater than liquid zinc level height, is convenient for then change, and is more specific, and the draw-in groove evenly sets up a plurality of fixing bolt 701 and nut 703 structurally, and coupling mechanism 7 contains bolt cover 702, and bolt cover 702 integrated into one piece's sleeve pipe 704, with the installation inserted bar 705 of sleeve pipe 704 looks adaptation, and tombarthite container 8 is installed to the bottom detachable of installation inserted bar 705. The inner diameter of the nut 703 is larger than the outer diameter of the bolt sleeve 702, the bolt sleeve 702 is used for preventing the rare earth container 8 from being driven by buoyancy to move upwards by the installation inserted rod 705, the side surface of the container barrel 801 is provided with the seepage hole 802, the rare earth can be galvanized by mixing the seepage hole 802 with the galvanizing liquid, the fixture block 707 and the bayonet 804 are matched for use, so that the rare earth container 8 can be conveniently detached, when the rare earth is required to be added, the installation inserted rod 705 directly moves downwards, the installation inserted rod 705 and the rare earth container 8 are taken out of the sleeve 704, the fixture block 707 is driven to rotate by rotating the installation inserted rod 705, the fixture block 707 and the bayonet 804 are right up, the fixture block 707 penetrates through the bayonet 804 to open the rare earth container 8, after the rare earth is filled, the inserted rod 705 is installed, the installation inserted rod 705 is sleeved into the sleeve 704, so that the rare earth can be continuously.
According to the invention, rare earth is added into the zinc plating solution through the rare earth adding device and prevented from floating upwards, so that the surface smoothness of the galvanized steel wire is high, no accretion exists, the device is convenient for supplementing the rare earth in time, the installation inserting rod can be directly moved downwards, the installation inserting rod and the rare earth container can be taken out, the installation inserting rod is rotated to drive the clamping block to rotate, the clamping block passes through the bayonet to open the rare earth container, after the rare earth is filled, the inserting rod is installed, and the installation inserting rod is sleeved into the sleeve pipe to continue to supplement rare earth metal into the zinc solution.
