[0020] See also Figure 2 , Figure 2 This is a stereogram of the optimal embodiment of a high-performance phosphor bronze strip production system of the present invention. Figure 2 As shown, at least one embodiment provides a high-performance phosphor bronze strip production system, including: a pickling component, the copper strip production system also includes a horizontal continuous casting component, a roller hearth furnace homogenization annealing component, a roughing mill blanking rolling component, a roller hearth furnace coarse strip annealing component, a double-sided face cutting component, a roughing mill rough rolling component, a trimming component, an air cushion furnace intermediate annealing component, a medium rolling mill intermediate rolling component, an air cushion furnace intermediate secondary annealing component, a finishing mill semi-finished material rolling component, an air cushion furnace semi-finished material annealing component, a semi-finished material pickling and polishing component, a finishing mill finishing rolling component, a degreasing and leveling component, an air cushion furnace low-temperature annealing component, a degreasing and rust-proofing component, a finished product stripping component and a bundling component. Specifically, the pickling component includes an outer protective tank 100 and an inner pickling tank 200 installed in the outer protective tank 100, and a drain port is provided on the bottom surface of one end of the inner pickling tank 200. A heat preservation cavity is formed between the inner wall of the outer protection tank 100 and the outer wall of the inner pickling tank 200, and a heat preservation structure is arranged in the heat preservation cavity.

[0021] Please continue reading Figure 2 Combined with Figure 3 , Figure 3 FIG. 2 is a cross-sectional view of a preferred embodiment of a high-performance phosphor bronze strip production system of the present invention. Figures 2 to 3 As shown, in order to improve the pickling accuracy of the copper strip, a pickling component with a multi-stage pickling effect is designed. Specifically, a plurality of partitions 300 are arranged inside the inner pickling tank 200, and a baffle 500 is arranged inside the partition 300. The baffle 500 extends to the outside of the partition 300. The partition 300 divides the inner pickling tank 200 into a plurality of grading chambers 400. Each grading chamber 400 is filled with pickling liquid, and the concentration of the pickling liquid increases successively from one side of the inner pickling tank 200 to the other side. Specifically, a unwinding device is arranged on one side of the pickling component, and a winding device is arranged on the other side. The copper strip extends from the unwinding device and first enters a pickling solution with a lower concentration, and then passes through pickling solutions with increasing concentrations in turn, and is finally collected into a disc by the winding device.

[0022] Please continue reading Figure 2 Combined with Figure 4 , Figure 4 2 is a three-dimensional cross-sectional view of the best embodiment of the baffle of the present invention. Figure 2 and Figure 4 As shown, in order to allow the pickling solution to be used directly after the concentration is increased or decreased, the partition 300 is designed to be a plate with a filtering effect. Specifically, each partition 300 includes two filter plates, and the baffle 500 is arranged between the two filter plates. The baffle 500 includes a pull-out plate 501, and the pull-out plate 501 is arranged between the two filter plates. The thickness of the pull-out plate 501 is equal to the distance between the two filter plates, and the width of the pull-out plate 501 is consistent with the length of the filter plate. Grooves 502 are provided on both sides of the bottom surface of the pull-out plate 501, and a brush 503 is provided in the groove 502. The brush 503 is suitable for cleaning the filter plate.

[0023] Please continue reading Figure 4 .like Figure 4 As shown, in order to avoid mixing of two pickling solutions of different concentrations during the movement of the copper strip, a splash guard 504 is installed on the top of the pull-out plate 501. The splash guard 504 not only has a heightening effect, but its convex surface can scrape off the liquid against the copper strip, and its concave surface can block the splashed liquid. Specifically, the top of the splash guard 504 is two arcuate convex surfaces 505, and the arcuate convex surfaces 505 extend above the two classification chambers 400 respectively. The side of the arcuate convex surface 505 facing the classification chamber 400 is a guide edge 507, and the guide edge 507 is suitable for abutting against the bottom surface of the copper strip. The bottom of the splash guard 504 is two arcuate concave surfaces 506 corresponding to the arcuate convex surface 505.

[0024] In summary, by setting up multiple grading chambers 400, the grading chambers 400 are filled with pickling solutions of different concentrations, thereby improving the pickling effect of the copper strip and enhancing the output accuracy of the copper strip; by setting up a partition 300 with a filtering effect, the pickling solution can be recycled after being discharged, thereby enhancing resource utilization without adding additional steps; by setting up a splash guard 504, when the copper strip shuttles through the grading chambers 400 with different concentrations, the mixing of pickling solutions from different concentrations can be avoided.
