Description

Technical Field

[0001] This utility model relates to the field of continuous casting technology, and in particular to a cooling device for continuous casting of non-ferrous metals. Background Technology

[0002] Non-ferrous metals, in a narrow sense, refer to non-ferrous metals, that is, all metals other than iron and iron-based alloys. Continuous casting technology is widely used in the production and manufacturing processes of non-ferrous metals. After liquid material is condensed into a semi-solid state in a crystallizer, it is pulled out from below and then further cooled by water spraying to form a billet with a certain cross-sectional shape and length. The billet needs to be fully cooled before it can be processed in the next step, so a cooling device is required to cool and lower the billet temperature.

[0003] Most existing cooling devices are cooling pools, in which freshly cast billets are placed to cool them down. However, the cooling water in the pool remains still, and the water temperature gradually rises during cooling, resulting in reduced cooling effect, poor cooling efficiency, and long cooling time.

[0048] Continuous casting technology is widely used in the production and manufacturing processes of non-ferrous metals. Liquid materials are condensed into a semi-solid state in a crystallizer and then pulled out from below. They are then further cooled by water spraying to form a billet with a specific cross-sectional shape and length. This billet needs to be sufficiently cooled before further processing. Most existing cooling devices are cooling tanks, where the freshly cast billet is placed to cool it thoroughly. However, the cooling water in the tank remains stagnant, causing the water temperature to gradually rise during cooling, resulting in reduced cooling efficiency, poor cooling effect, and prolonged processing time.

[0049] Reference Figures 1 to 4 As shown, a cooling device for continuous casting of non-ferrous metals according to an embodiment of the present invention includes: a cooling box 100, a support part 200, a cooling assembly, and a stirring device 500.

[0050] The cooling tank 100 has a cooling trough 101 with an opening at the top, and is provided with an inlet and an outlet that communicate with the cooling trough 101. A certain amount of cooling water can be pre-filled into the cooling trough 101.

[0051] The support part 200 is disposed in the cooling tank 101 and is used to place the casting billet; obviously, when cooling the casting billet, the cooling water covers the casting billet on the support part 200.

[0052] The cooling assembly includes a circulating water tank 300 and a circulation device 400. The circulating water tank 300 contains cooling water, and the circulation device 400 is located between the circulating water tank 300 and the cooling tank 100 to circulate and transport cooling water between them. In some embodiments, the circulation device 400 includes a circulation pump 410, a first circulation pipe 420, and a second circulation pipe 430. The circulation pump 410 is installed in the circulating water tank 300. The first circulation pipe 420 connects the circulation pump 410 to the inlet of the cooling tank 100, and the second circulation pipe 430 connects the circulating water tank 300 to the outlet of the cooling tank 100. The circulation pump 410 pumps the cooling water from the circulating water tank 300 to the cooling tank 100 via the first circulation pipe 420, and then returns it to the circulating water tank 300 via the second circulation pipe 430, thus repeating the cycle.

[0053] A stirring device 500 is installed in the cooling tank 100. The stirring device 500 is used to stir the cooling water in the cooling tank 101, so that the cooling water in the cooling tank 101 fluctuates and mixes evenly.

[0054] When using the cooling device for continuous casting of non-ferrous metals according to this embodiment of the utility model, the circulation device 400 can be started first to make the cooling water circulate between the circulating water tank 300 and the cooling tank 100. At the same time, the cooling water in the cooling tank 101 is stirred by the stirring device 500, making the cooling water in the cooling tank 101 fluctuate. Then, the casting billet to be cooled is placed on the support part 200, and the casting billet is cooled by the circulating cooling water. Since the water is circulating, the rate of temperature rise in the cooling tank 101 can be effectively reduced, resulting in good cooling effect and high cooling efficiency. At the same time, since the stirring device 500 can stir the cooling water in the cooling tank 101, the cooling water can be fluctuated and mixed more evenly, ensuring the uniformity of the cooling effect and further improving the cooling effect. In addition, when the cooling water is stirred, the contact area with the outside air will also increase, resulting in faster heat dissipation.

[0055] Reference Figure 1 and Figure 4 As shown, in some embodiments of this utility model, the agitation device 500 includes a blower (not shown) and an aeration pipe 510. The aeration pipe 510 is connected to the air outlet side of the blower, and the aeration pipe 510 is at least partially located in the cooling tank 101. The aeration pipe 510 is provided with a plurality of aeration holes 511. The height of the aeration holes 511 is lower than the height of the water outlet of the cooling tank 100. The aeration pipe 510 can supply air to the cooling water in the cooling tank 101 through the aeration holes 511, thereby agitating the cooling water in the cooling tank 101.

[0056] It is conceivable that the cooling water in the cooling tank 101 is agitated by aeration through aeration pipe 510. On the one hand, aeration pipe 510 occupies little space, providing more space for the support unit 200. On the other hand, the installation and arrangement of aeration pipe 510 is also very convenient.

[0057] In a further embodiment, the agitation device 500 also includes a main air supply pipe 520, which is connected to the air outlet of the fan. Multiple aeration pipes 510 are provided and are all connected to the main air supply pipe 520. The aeration pipes 510 are evenly arranged along the circulation direction of the cooling water. In this way, air can be supplied to multiple aeration pipes 510 through the main air supply pipe 520, thereby aerating multiple locations in the cooling tank 101 and agitating the cooling water in the cooling tank 101 more fully and evenly.

[0058] Reference Figures 2 to 4As shown, in some embodiments of this utility model, the aeration pipe 510 includes a first pipe section 512, a second pipe section 513, and a third pipe section 514. The first pipe section 512 is disposed inside the cooling tank 101 and located below the supporting part 200, and an aeration hole 511 is provided on the first pipe section 512. The second pipe section 513 and the third pipe section 514 are respectively connected to the two ends of the first pipe section 512 and both extend to the outside of the cooling tank 101. The second pipe section 513 is used to connect to the main air supply pipe 520, and then to the fan, while the end of the third pipe section 514 is a closed end.

[0059] Understandably, by setting the first pipe section 512 and placing it below the support section 200, the cooling water around the billet placed on the support section 200 can be stirred more thoroughly, thereby improving the cooling effect and cooling speed of the billet.

[0060] Furthermore, a first snap-fit ​​portion 102 and a second snap-fit ​​portion 106 are respectively provided on opposite sides of the cooling tank 100. Both the first snap-fit ​​portion 102 and the second snap-fit ​​portion 106 are located on the outside of the cooling tank 101. The first snap-fit ​​portion 102 is provided with a first snap-fit ​​groove 103 that is adapted to the second pipe section 513 and is elastic. The second snap-fit ​​portion 106 is provided with a second snap-fit ​​groove 107 that is adapted to the third pipe section 514 and is elastic. The second pipe section 513 is snapped into the first snap-fit ​​groove 103 and the third pipe section 514 is snapped into the second snap-fit ​​groove 107. By setting the above structure, on the one hand, the structural stability of the aeration pipe 510 during aeration can be improved, and on the other hand, the aeration pipe 510 can be easily disassembled and assembled.

[0061] It is conceivable that a bracket could also be installed on the outside of the cooling box 100 for mounting the main gas pipe 520.

[0062] Reference Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the aeration holes 511 on the first pipe section 512 are arranged with downward openings. This arrangement can reduce the resistance of aeration. At the same time, the downward opening of the aeration holes 511 can prevent slag falling from the billet from entering the aeration holes 511 and clogging them.

[0063] Furthermore, the bottom wall of the cooling tank 101 is provided with a guide portion 104, which is located below the first pipe section 512. The guide portion 104 is configured to guide the gas output from the aeration holes 511 of the first pipe section 512 to flow upward, thereby driving the cooling water to flow upward, so as to make the cooling water mix more evenly and improve the cooling effect. In some specific embodiments, the guide portion 104 is provided with a guide surface 105 on the side facing the first pipe section 512. The guide surface 105 is arc-shaped. This design helps to guide the gas and cooling water to rise smoothly along the guide surface 105 and reduce flow resistance.

[0064] Reference Figure 2 and Figure 3 As shown, in some embodiments of this utility model, a lifting assembly 600 is provided between the cooling box 100 and the supporting part 200. The lifting assembly 600 is used to drive the supporting part 200 to rise and fall relative to the cooling box 100. Thus, when placing the casting billet, the lifting assembly 600 can drive the supporting part 200 to rise to a position convenient for the operator to place the casting billet, and then the supporting part 200 can be reset and submerged in the cooling water for cooling. After cooling, the lifting assembly 600 can be driven to rise the supporting part 200 to a position convenient for the operator to pick up the casting billet. This saves time and effort, greatly reduces the workload of the staff, and improves the cooling efficiency.

[0065] Reference Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the lifting assembly 600 includes a screw 610, a drive motor 620, and a threaded seat 630. Two lifting assemblies 600 are provided, respectively connected to opposite sides of the bearing portion 200. The screw 610 is rotatably mounted on the cooling box 100 and extends vertically. The drive motor 620 is connected to the screw 610 and is used to drive the screw 610 to rotate. The threaded seat 630 is threadedly engaged with the screw 610 and is connected to the bearing portion 200. Based on the above configuration, the drive motor 620 can drive the screw 610 to rotate, thereby driving the threaded seat 630 and the bearing portion 200 to move up and down. The structure is simple and practical. It should be noted that the drive motors 620 of the two lifting assemblies 600 rotate synchronously.

[0066] It is conceivable that, in order to make the lifting of the support unit 200 more stable and smooth, the cooling box 100 is also provided with several guide rods 108. The guide rods 108 extend vertically, and the support unit 200 is provided with guide holes to slide vertically with the guide rods 108.

[0067] Reference Figure 2 and Figure 3As shown, in some embodiments of this utility model, the lifting assembly 600 is disposed at the top of the cooling box 100 and located outside the cooling tank 101. The supporting part 200 includes a supporting basket 210 and a connecting frame 220. The supporting basket 210 has a receiving groove 211 with an open top for placing the casting billet. The side wall and bottom wall of the receiving groove 211 are provided with water passage holes 212 penetrating the supporting basket 210 so that the cooling water can fully contact the casting billet for cooling. The connecting frame 220 is connected to the supporting basket 210 and extends to the outside of the cooling tank 101. The threaded seat 630 is connected to the connecting frame 220. By adopting the above-mentioned structural arrangement, the lifting assembly 600 and the cooling box 100 can be placed outside the cooling tank 101, thereby avoiding contact with the cooling water and corrosion, and extending the service life. It can be understood that in some embodiments, two lifting assemblies 600 are provided, and therefore two connecting frames 220 are also provided, with guide holes provided on the connecting frame 220.
