Description

Technical Field

[0001] This utility model belongs to the field of copper rod cooling, and specifically designs a copper rod and copper ingot cooling device. Background Technology

[0002] In traditional copper rod production, the cooling of the crystallizing wheel and steel strip during casting often employs a single-temperature, single-cooling-zone cooling method. This method cannot adjust the water flow rate or cooling temperature in different areas of the crystallizing wheel or steel strip. Currently, even the more advanced companies on the market can only control the cooling of copper ingots by adjusting the water flow rate. Although this method can adjust the temperature of the copper ingots according to the temperature of the molten copper in the furnace, it is difficult to control the different cooling efficiencies required in different areas. Furthermore, it cannot be adjusted according to changes in the temperature of the molten copper or the speed of production, making it difficult to achieve higher precision control.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] The following is combined Figure 1-4 This invention describes a copper rod and copper ingot cooling device, comprising a working space 1, a crystallizing wheel assembly 2 rotatably connected within the working space 1, and a cooling mechanism 3 for cooling the crystallizing wheel assembly 2. The crystallizing wheel assembly 2 includes a crystallizing wheel 21 rotatably connected within the working space 1 and steel strips 22 distributed around the crystallizing wheel 21, forming a cooling space for the copper rod and copper ingot between the steel strips 22 and the crystallizing wheel 21. The cooling mechanism 3 includes steel strip 22 cooling components connected within the working space 1 for zoned cooling of the steel strips 22. The crystallizing wheel 21 is provided with an inner ring cooling component 32 and an end face cooling component 33 on one side to cool its inner ring and end face. The cooling components of the steel strip 22, the inner ring cooling component 32, and the end face cooling component 33 correspond to multiple areas of the steel strip 22, the inner ring of the crystallizing wheel 21, and the end face of the crystallizing wheel 21, respectively, and can be independently controlled for cooling. This allows for adjustments based on changes in the copper molten metal temperature and the production speed. In other words, it enables control of different areas of the inner ring and end face of the crystallizing wheel 21, as well as individual control of different areas of the steel strip 22, according to actual temperature control requirements, in order to achieve higher precision control.

[0027] Please refer to Figures 2-3As shown, the cooling component of the steel strip 22 includes a steel strip 22 fluid pipe distributed along the length of the working surface of the steel strip 22, wherein the length of the working surface refers to the length of the cooling zone of the copper rod / ingot. The steel strip 22 fluid pipe is fixedly connected to the working space 1. At least four independently controllable steel strip 22 cooling zones are formed on the steel strip 22 fluid pipe. Each steel strip 22 cooling zone includes multiple first nozzles 312 connected to the steel strip 22 fluid pipe. When cooling the steel strip 22, if the steel strip 22 cools down too quickly, it will cause residual stress and deformation / cracking, and the grain refinement will lead to a decrease in ductility. If the cooling is too slow, it will lead to problems such as coarse grains, severe oxidation, and low cooling efficiency. The temperature of the steel strip 22 acting on the copper liquid is different from the front end to the back end, that is, the cooling temperature of the back end of the steel strip 22 is higher than the cooling temperature of the front end of the steel strip 22. By forming multiple steel strip 22 cooling zones and supplying cooling fluids of different temperatures, the different areas of the steel strip 22 can be precisely controlled to avoid the performance reduction of the copper rod / ingot caused by a single cooling temperature acting on the steel strip 22.

[0028] Please refer to Figures 2-3 As shown, the first nozzle 312 is a shower nozzle that sprays water onto the end face of the steel strip 22, thereby controlling the temperature of different fluids in different areas of the steel strip 22 and achieving temperature control of different temperatures of the steel strip 22, that is, controlling the cooling temperature of the copper rod and copper ingot at different stages of the crystallization cooling process.

[0029] Please refer to Figures 2-3 As shown, the inner ring cooling component 32 includes an inner ring fluid pipe 321 fixedly connected to the working space 1. At least three independently controllable inner ring cooling zones are formed on the inner ring fluid pipe 321. Similar to the steel strip 22, different areas of the crystallizing wheel 21 have different cooling temperatures for the copper rod and copper ingot. Cooling the crystallizing wheel 21 at a single temperature will affect the product performance of the copper rod and copper ingot. By setting multiple sets of inner ring cooling zones in the inner ring of the crystallizing wheel 21 to correspond to the cooling in different areas of the crystallizing wheel 21, the cooling of the copper rod and copper ingot in the cavity can be precisely controlled. This allows for precise temperature control of the copper rod and copper ingot at different stages of cooling and crystallization, thereby improving the performance after crystallization and cooling. Each inner ring cooling zone is provided with multiple second nozzles 322 connected to the inner ring fluid pipe 321. The second nozzles 322 are directed towards the inner ring of the crystallizing wheel 21 for cooling.

[0030] Please refer to Figures 2-3 As shown, the second nozzle 322 is connected to the inner ring fluid pipe 321 of the wheel through a universal connection structure. The universal connection structure is a conventional technology, which can be achieved by using a universal joint or other connection methods. It is a conventional technology in this field and will not be described in detail here.

[0031] Please refer to Figures 2-3As shown, the spraying end of the second nozzle 322 is not perpendicular to the inner ring of the wheel. The spraying angle avoids being perpendicular to the inner ring of the wheel, which can reduce water splashing and avoid affecting the equipment's production of copper rods and copper ingots.

[0032] Please refer to Figure 3 As shown, the second nozzle 322 is an adjustable nozzle. Adjustable nozzles are a conventional technology, which can control the spray volume of the second nozzle 322 to control the flow rate, splash volume, and flow velocity of the water sprayed onto the inner ring of the wheel, thereby improving the cooling effect.

[0033] Please refer to Figure 4 As shown, the wheel end face cooling component 33 includes a wheel end face spray pipe 331 fixedly connected to the working space 1. At least four independently controllable wheel end face cooling zones are formed on the wheel end face spray pipe 331. The end face of the crystallizing wheel 21 affects the cooling temperature of the copper rod and copper ingot. In this embodiment, the cooling of the end face of the crystallizing wheel 21 is formed in four regions, corresponding to the cooling of different regions of the end face of the crystallizing wheel 21. That is, different cooling temperatures are controlled for the copper rod and copper ingot in the cavity at different stages of cooling. Each wheel end face cooling zone includes multiple third nozzles 332 connected to the wheel end face spray pipe.

[0034] Please refer to Figure 3 As shown, the third nozzle 332 is a rain nozzle, which is used to spray cooling towards the end face of the crystallizing wheel 21.

[0035] Please refer to Figure 2 As shown, a guide groove 11 is formed at the bottom of the workspace 1 to improve the guidance of cooling fluid discharge.

[0036] Working principle of this utility model:

[0037] High-temperature molten copper is poured into the cavity formed by the crystallizing wheel 21 and the steel strip 22;

[0038] The steel strip 22 cooling component is zoned sprayed, meaning that during different stages of cooling and crystallization of the copper rod and copper ingot, cooling fluids of different temperatures are delivered through multiple steel strip 22 cooling zones to control the cooling of the copper rod and copper ingot. At the same time, the solidification rate of the copper ingot surface can be controlled, thereby improving cooling efficiency and cooling quality.

[0039] The inner ring cooling component 32 cools the crystallizing wheel 21, that is, it cools the end face of the cavity. The principle is the same as that of the steel strip 22. Through multiple inner ring cooling zones, the cooling temperature of different areas of the crystallizing wheel 21 acting on the cooling of copper rod and copper ingot is controlled, so as to realize the zoned control of the cooling temperature of copper rod and copper ingot at different stages to reduce thermal deformation and improve cooling efficiency.

[0040] The wheel end face cooling component 33 can suppress the temperature rise of the wheel rim. Similarly, it can achieve different temperatures for different areas of the crystallizing wheel 21 to improve the production performance and efficiency of copper rods and copper ingots.

[0041] Among them, multiple steel strip cooling zones, inner ring cooling zones, and end face cooling zones are all independently controlled by solenoid valves to control the temperature and flow rate in different areas of the crystallizing wheel and steel strip.

[0042] The coolant flows back to the treatment system via the guide channel 11.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
