An aluminum water tank is arranged inside the copper water tank. The space between the copper water tank and the aluminum water tank is used for storing copper water, and the aluminum water tank is used for storing aluminum water. A continuous casting assembly is used for shaping the copper-clad aluminum material; and a heat exchange assembly is used for reducing the temperature of the aluminum water.

Description

Technical Field

[0001] The invention relates to the technical field of copper-clad aluminum continuous casting, and in particular to a horizontal continuous casting device for a copper-aluminum transition anti-corrosion terminal. Background Art

[0002] Copper clad aluminum busbar is an energy-saving conductor material, consisting of an aluminum core and a copper cladding layer. It has the advantages of copper's excellent conductivity and good corrosion resistance as well as aluminum's low cost and light weight. It also has the characteristics of copper's conductivity and aluminum's low density. Copper clad aluminum busbar is generally produced by continuous casting process.

[0003] For example, the patent announcement number CN106111922B discloses "a copper-clad aluminum composite material high-efficiency continuous casting forming equipment and process", which mainly consists of a copper melting furnace and a heat preservation furnace, an aluminum melting furnace, an aluminum flow trough, an aluminum heat preservation bag, a composite mold, a composite heat preservation furnace, a crystallizer, a first and second cooling device, a second and second cooling device, a traction device, a sawing device, a temperature measuring device and an integrated control system;

[0004] Among them, the copper material and the aluminum material are melted separately and kept warm separately to provide molten copper and molten aluminum for the subsequent continuous casting work. The molten copper and molten aluminum are in contact with the air and react with oxygen, which will cause a waste of raw materials and affect the quality of the copper-clad aluminum bar to a certain extent. On the other hand, since the overall area of ​​the container containing the molten copper and molten aluminum in contact with the air is large, the heat of the molten copper and molten aluminum is dissipated more. Therefore, during the insulation process, the required heat is also increased;

[0005] On the one hand, there is a waste of raw materials, and on the other hand, there is a high energy consumption. Summary of the invention

DETAILED DESCRIPTION

[0071] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0072] Embodiment 1:

[0073] A horizontal continuous casting device for copper-aluminum transition anti-corrosion terminals, such as Figure 1-13 As shown, including:

[0074] The copper water tank 101 has a closed top wall, and the aluminum water tank 107 is fixedly arranged inside the copper water tank 101. The copper water tank 101 and the aluminum water tank 107 are used to store copper water, and the aluminum water tank 107 is used to store aluminum water. The aluminum water tank 107 is arranged inside the copper water tank 101, so that in the process of heating and melting the copper material, the aluminum material is heated through the heat conduction of the aluminum water tank 107 to melt the aluminum material. Since the aluminum water tank 107 is covered by the copper water, in the process of heating and melting the aluminum material, compared with the separate heating in the prior art, the heat utilization efficiency is improved to reduce energy consumption.

[0075] The continuous casting assembly is arranged below the copper water tank 101 and is used for molding the copper-clad aluminum material; Figure 4 , Figure 8 and Fig.13 As shown, the continuous casting assembly includes:

[0076] The steel mold 701 includes an outer mold 7011 and an inner mold 7012. The inner mold 7012 passes through the outer mold 7011, so that a space for shaping the molten copper is formed between the outer mold 7011 and the inner mold 7012;

[0077] Crystallizer 702, which is fixed to the open end of the steel mold 701;

[0078] The copper water delivery pipe 704, the lower end of the copper water delivery pipe 704 is fixed to the steel mold 701, and the copper water delivery pipe 704 is connected to the inner cavity of the outer mold 7011, and the upper end of the copper water delivery pipe 704 extends to the inner cavity of the copper water tank 101 avoiding the aluminum water tank 107;

[0079] A second molten aluminum delivery pipe 703, the lower end of which is in communication with the inner mold 7012, the upper end of which is provided with a heat conduction pipe 805, the upper end of which is connected with the first molten aluminum delivery pipe 104, the upper end of which extends to the inner cavity of the molten aluminum tank 107;

[0080] like Figure 7 As shown, the two transmission rods 105 are both slidable up and down and penetrate the top of the copper water tank 101; two plugs 109 are respectively fixed at the bottom ends of the two transmission rods 105, one of the bottom ends of the transmission rod 105 is located in the inner cavity of the aluminum water tank 107, and the other bottom end of the transmission rod 105 is located in the inner cavity of the copper water tank 101 avoiding the aluminum water tank 107, and the two plugs 109 are used to seal the copper water delivery pipe 704 and the first aluminum water delivery pipe 104 respectively;

[0081] The protection tube 108 is vertically fixed on the inner bottom wall of the aluminum water tank 107 , and one of the transmission rods 105 passes through the protection tube 108 and extends to the inner cavity of the copper water tank 101 .

[0082] The driving rod 105 moves up and down to drive the plug 109 to move up and down. When the plug 109 moves up, the molten copper can enter the steel mold 701 through the molten copper delivery pipe 704, and the molten aluminum can enter the steel mold 701 through the first molten aluminum delivery pipe 104, the heat conduction pipe 805, and the second molten aluminum delivery pipe 703 in sequence to realize the continuous casting of copper-clad aluminum materials.

[0083] Heat exchange components are used to reduce the temperature of molten aluminum; such as Figure 5 As shown, the heat exchange component includes:

[0084] A heat conducting pipe 805, which is fixed between the first molten aluminum conveying pipe 104 and the second molten aluminum conveying pipe 703;

[0085] The heat exchange box 801 is hollow inside and is fixedly mounted on the heat conducting pipe 805. Two water valves 806 are installed on the side wall of the heat exchange box 801. The water valves 806 can be switched on and off by using an electric control valve. The two water valves 806 are respectively connected to the input end and the output end of the external water cooling circulation system;

[0086] Connecting seats 803 are fixedly installed on the two opposite side walls of the heat exchange box 801, and a plurality of parallel square tubes 804 are fixedly connected between the two connecting seats 803. The square tubes 804 are located inside the heat exchange box 801, and one of the connecting seats 803 is connected to the first gas pipe 504 in the circulation component, and the other connecting seat 803 is connected to the second gas pipe 802 in the circulation component.

[0087] During the continuous casting process, the molten aluminum transfers heat to the heat exchange box 801 through the heat pipe 805, heating the water in the heat exchange box 801 to create a steam environment in the heat exchange box 801, which is convenient for cooperating with the circulation components to achieve efficient heat exchange. The water valve 806 and the external water cooling circulation system are used to assist in cooling to ensure that the molten aluminum is within the appropriate temperature range after passing through the heat pipe 805.

[0088] The side wall of the storage box 301 is provided with a plurality of connection components, and the plurality of connection components are fixed to the copper water tank 101;

[0089] The mesh plate 308 is fixed on the inner bottom wall of the material storage box 301, and the upper surface of the mesh plate 308 is used to store copper and aluminum materials;

[0090] The push plate 306 is rotatably arranged on the top of the mesh plate 308. The push plate 306 divides the inner cavity of the material storage box 301 into two independent spaces. The push plate 306 is used to isolate the copper material and the aluminum material.

[0091] The conveying assembly is arranged at the bottom of the storage box 301. Figure 10-12 As shown, including:

[0092] The first feeding pipe 304 and the second feeding pipe 305 are both fixed at the bottom of the material storage box 301, and the first feeding pipe 304 and the second feeding pipe 305 are both penetrated to be flush with the top wall of the mesh plate 308;

[0093] The two gate plates 307 are embedded and fixed on the side wall of the push plate 306, and the two gate plates 307 are used to seal the ends of the first feeding pipe 304 and the second feeding pipe 305 respectively;

[0094] Motor 303, the motor 303 is fixed on the top of the material storage box 301, and the output shaft of the motor 303 is fixedly connected to the push plate 306;

[0095] The two connecting tubes 106 are both set through the top of the copper water tank 101, and the two connecting tubes 106 are respectively connected to the first feeding tube 304 and the second feeding tube 305 one by one. The lower end opening of one of the connecting tubes 106 is located between the copper water tank 101 and the aluminum water tank 107, and the lower end opening of the other connecting tube 106 is located above the aluminum water tank 107.

[0096] During operation, the motor 303 drives the push plate 306 to rotate, and the push plate 306 drives the gate plate 307 to rotate. When the gate plate 307 is away from the corresponding first feeding pipe 304 or the second feeding pipe 305, the copper water tank 101 and the storage box 301 are connected, thereby facilitating the addition of copper and aluminum materials. Conversely, when the gate plate 307 seals the top openings of the first feeding pipe 304 and the second feeding pipe 305, the seal between the copper water tank 101 and the storage box 301 is achieved. At this time, the copper water tank 101 is heated, and the high-temperature gas in the copper water tank 101 will not enter the storage box 301, thereby preventing the copper and aluminum materials from melting in the storage box 301.

[0097] The circulation component is arranged on the top of the storage box 301, and the circulation component is used for the gas circulation inside the storage box 301 to heat the gas inside the storage box 301, such as Figure 1 , Figure 3-Figure 5 As shown, including:

[0098] An air pump box 501 is fixed on the top of the material storage box 301, and an air pump is arranged in the air pump box 501;

[0099] A three-way pipe 503, one end of which is connected to the output port of the air pump, and the other two ends of the three-way pipe 503 are respectively provided with a one-way valve 505 and a valve 506, and the valve 506 is an electric control valve that can be turned on and off;

[0100] A first gas delivery pipe 504, the first gas delivery pipe 504 is in communication with the valve 506, and the first gas delivery pipe 504 is in communication with one of the communication seats 803;

[0101] A second gas delivery pipe 802, the second gas delivery pipe 802 is connected to another connecting seat 803, and the free end of the second gas delivery pipe 802 extends to the inner cavity of the storage box 301;

[0102] A three-way hose 502, one end of which is connected to the input port of the air pump, two feed ports are provided on the top of the storage box 301, and gates 302 are hinged at the top of the storage box 301 near the feed ports. The gates 302 are rotated to open or close the corresponding feed ports, and the other two ends of the three-way hose 502 respectively pass through the two gates 302 and are connected to the inner cavity of the storage box 301.

[0103] By controlling the valve 506, the output position of the gas in the storage box 301 is adjusted. When the valve 506 is closed, the gas in the storage box 301 is output to the external environment through the one-way valve 505. When the valve 506 is connected, the gas in the storage box 301 can circulate in the storage box 301 through the first gas pipe 504, the second gas pipe 802, the connecting seat 803 and the multiple square tubes 804.

[0104] like Fig. 9 As shown, it also includes:

[0105] Gas tank 401, gas tank 401 is fixed on the side wall of storage box 301;

[0106] Solenoid valve 402, the solenoid valve 402 is installed at the gas outlet of the gas tank 401;

[0107] The tube body 403 has one end connected to the electromagnetic valve 402 and the other end extending to the inner cavity of the material storage box 301 .

[0108] Each time copper and aluminum materials are added, the gas in the storage box 301 needs to be extracted into the external environment. At this time, by controlling the solenoid valve 402, the inert gas stored in the gas tank 401 can enter the storage box 301 through the tube body 403 to achieve the replacement of the gas in the storage box 301.

[0109] The heating component is arranged near the copper water tank 101 and is used to heat the copper material and the aluminum material. The heating component includes a control cabinet 601 and a coil 602. A control system is arranged in the control cabinet 601, and the control system and the coil 602 are electrically connected. The coil 602 is a spiral structure, and the copper water tank 101 is inside the coil 602.

[0110] The protection box 102 is fixed on the top of the copper water tank 101, and the top ends of the two transmission rods 105 are both in the protection box 102; the two electric push rods 103 are both fixed on the top of the protection box 102, and the telescopic ends of the two electric push rods 103 are respectively connected and fixed with the two transmission rods 105 one by one.

[0111] Furthermore, the connection component includes:

[0112] Two ear plates 202, the two ear plates 202 are respectively fixed to the copper water tank 101 and the storage box 301;

[0113] The hydraulic push rod 201 is fixed to one of the ear plates 202, and the telescopic end of the hydraulic push rod 201 is fixed to the other ear plate 202. When performing equipment maintenance, the door of the protection box 102 is opened, the connection between the electric push rod 103 and the transmission rod 105 is disconnected, and the connection between the first feed pipe 304, the second feed pipe 305 and the two connecting pipes 106 is disconnected, and the storage box 301 can be raised by the hydraulic push rod 201, and the distance between the storage box 301 and the copper water tank 101 is increased, so that the staff can perform pipeline cleaning and maintenance.

[0114] Compared with the conventional technology of using two ladles to store molten copper and molten aluminum respectively, the present invention reduces heat loss, thereby reducing the energy consumption required during the heat preservation process;

[0115] Through the circulation component and the heat exchange component, the output molten aluminum can be cooled by gas circulation to ensure the normal continuous casting of copper-clad aluminum materials. The heated gas preheats the copper and aluminum materials through the circulation component to improve the utilization rate of heat.

[0116] Working principle: First, open the two gates 302, put the copper material and the aluminum material into the storage box 301 through the two feeding holes respectively, so that the copper material and the aluminum material are respectively on both sides of the push plate 306, and then the push plate 306 is driven to rotate by the motor 303. When the push plate 306 rotates, the gate plate 307 is driven to move, so that the storage box 301 and the copper water tank 101 are connected through the first feeding pipe 304, the second feeding pipe 305 and the corresponding connecting pipe 106, and the push plate 306 is driven by the motor 303 to reciprocate. During the process, the push plate 306 can push the copper material and the aluminum material to move on the mesh plate 308, and control the push plate 306 to reciprocate within 180 degrees, so that the copper material can only fall into the space between the copper water tank 101 and the aluminum water tank 107 through the second feeding pipe 305 and the corresponding connecting pipe 106, and the aluminum material can only fall into the aluminum water tank 107 through the first feeding pipe 304 and the corresponding connecting pipe 106, and then add the copper material and the aluminum material to the storage box 301, and finally close the gate 302, so that the storage box 301 is in a sealed state;

[0117] Then, the heat exchange box 801 is connected to the circulating water cooling system through two water valves 806, and a certain amount of water is injected into the heat exchange box 801 through the circulating water cooling system, and then the two water valves 806 are closed;

[0118] Close valve 506 and turn on the switch of the air pump. When the air pump is working, the gas in the storage box 301 and the copper water tank 101 is extracted through the three-way hose 502. Since the valve 506 is closed, the gas extracted by the air pump is discharged through the three-way pipe 503 and the one-way valve 505 until the air pressure in the copper water tank 101 and the storage box 301 is lower than the set threshold value, thereby reducing the amount of oxygen inside the device. Then, turn on the switch of the electromagnetic valve 402, and the inert gas in the gas tank 401 enters the storage box 301 and the copper water tank 101 through the electromagnetic valve 402 and the tube body 403, so that the copper material and the aluminum material are in a low oxygen environment when they are melted, thereby reducing the amount of raw materials wasted due to oxidation;

[0119] After the continuous casting work has been carried out for a period of time, when copper and aluminum materials need to be added, the motor 303 is used to control the push plate 306 to rotate to the initial position, that is, the two gates 307 on the push plate 306 seal the first feed pipe 304 and the second feed pipe 305, and then the gate 302 is opened to add copper and aluminum materials. Then, the gas inside the storage box 301 is extracted and the inert gas in the gas tank 401 is filled into the storage box 301 through the control of the valve 506 and the solenoid valve 402 again, thereby preventing oxygen from entering the interior of the device during the filling process.

[0120] When heating and melting the copper and aluminum materials, the push plate 306 needs to be controlled by the motor 303 to move to the initial position, that is, the two gates 307 on the push plate 306 seal the first feed pipe 304 and the second feed pipe 305 to prevent the high-temperature gas inside the copper water tank 101 from entering the storage box 301, and the power of the coil 602 is turned on, and the control system in the control cabinet 601 is cooperated to heat and melt the copper in the copper water tank 101 and the aluminum in the aluminum water tank 107 in the form of electromagnetic heating. When the copper material is melted, the heat of the copper water is transferred to the aluminum water tank 107 to melt the aluminum material, and then the electromagnetic heating in the copper water tank 101 is realized through the operation of the control system and the coil 602 to improve the melting effect, and then the copper water and the aluminum water can be left to stand to achieve the precipitation of impurities;

[0121] During continuous casting, the electric push rod 103 drives the corresponding transmission rod 105 to rise, thereby driving the plug 109 to rise, so that the molten copper can enter the gap between the outer mold 7011 and the inner mold 7012 through the molten copper delivery pipe 704, and is output in a tubular shape from the end of the steel mold 701, thereby realizing continuous casting of the copper tube. The molten aluminum enters the heat conducting pipe 805 through the first molten aluminum delivery pipe 104, and then enters the inner mold 7012 through the heat conducting pipe 805 and the second molten aluminum delivery pipe 703, and is output in a rod shape from the end of the steel mold 701, thereby realizing continuous casting of copper-clad aluminum in cooperation with the function of the crystallizer 702.

[0122] Since the temperature of the molten aluminum in the molten aluminum tank 107 is relatively high, when the molten aluminum passes through the heat conducting pipe 805, the water inside the heat exchange box 801 is heated, so that the inside of the heat exchange box 801 is filled with high-temperature steam, thereby cooling the molten aluminum and facilitating the normal continuous casting of the copper-clad aluminum material.

[0123] At the beginning of the continuous casting work, turn on the switch of valve 506, and turn on the switch of the air pump again. At this time, when the air pump is working, the gas in the storage box 301 is extracted through the three-way hose 502, and the gas is pumped into the three-way pipe 503. The gas passes through the valve 506 and the first gas pipe 504 and enters one of the connecting seats 803, and then passes through multiple square tubes 804 to enter another connecting seat 803, and finally returns to the inner cavity of the storage box 301 through the second gas pipe 802 to realize the circulation of the gas. In this process, when the gas flows through the square tube 804, it exchanges heat with the steam inside the heat exchange box 801 to realize the recovery of excess heat of the aluminum liquid, and uses the heat to preheat the copper and aluminum materials inside the storage box 301 to realize the full utilization of energy.

[0124] Temperature monitoring equipment is provided in the copper water tank 101 and the heat exchange box 801. The temperature monitoring equipment in the copper water tank 101 is used to cooperate with the control system and the coil 602 to ensure that the copper water is kept in an appropriate temperature range. The temperature monitoring equipment inside the heat exchange box 801 can indirectly monitor the temperature of the aluminum water flowing out through the heat pipe 805. When the temperature of the aluminum water in the heat pipe 805 is too high, it is not conducive to the continuous casting work. At this time, it is necessary to open the water valve 806 and cooperate with the circulating water cooling system to assist in cooling the aluminum water. Since the temperature monitoring system and the temperature monitoring equipment have been maturely applied in the metal smelting industry and are not the main innovation of the present invention, they are not repeated here.

[0125] In the present invention, except for the aluminum water tank 107, the heat pipe 805 and the square tube 804 and other components used for heat exchange, all other components should be made of thermal insulation materials. In addition, the protection box 102 and the air pump box 501 also need to be made of thermal insulation materials to prevent heat leakage.

[0126] Embodiment 2: includes all the contents of Embodiment 1, except that:

[0127] During the melting stage, the flow rate of the inert gas needs to cover the surface of the molten pool to prevent oxidation, and the flow rate is proportional to the surface area of ​​the molten pool. When the aluminum and copper are completely melted and enter the insulation stage, the output amount of inert gas is constant, and the gas consumption rate of the aluminum water tank 107 is B 1， Gas consumption rate B of copper water tank 101 2 ;

[0128] The inert gas in the gas tank 401 is output to the outside according to the following model:

[0131] The higher the temperature, the shorter the melting time. Suppose the melting time of aluminum and copper is T 1 and T 2 is proportional to the mass of the material:

[0133] ;

[0134] Gas consumption is proportional to the surface area of ​​copper and aluminum and time, and there is also a certain relationship between surface area and mass. Suppose the surface area of ​​aluminum and copper is S 1 , S 2 With quality M 1 、M 2 The relationship is:

[0135] ;

[0136] ;

[0137] In order to more accurately simulate the inert gas consumption of copper and aluminum in the same temperature environment, a weight coefficient is introduced to dynamically adjust the distribution of gas consumption. This adjustment will be based on the real-time remaining copper and aluminum mass, as well as the actual situation that the aluminum furnace is surrounded by the copper furnace. 1 and w 2 They are the weight coefficients of the aluminum water tank 107 and the copper water tank 101, which are 0.5714 and 0.4286 respectively.

[0138] Considering that the aluminum furnace is surrounded by the copper furnace, the gas flow and heat transfer around the aluminum furnace will be restricted, so it is necessary to introduce more complex factors to correct the spatial weight coefficient;

[0139] Influence of enclosure effect: The aluminum furnace is surrounded by the copper furnace, the gas flow is restricted, and the heat transfer efficiency is reduced. Introduce an enclosure effect coefficient To reflect this effect, the geometry of the aluminum and copper furnaces also affects gas flow and heat transfer. We can introduce the geometric shape factor and to reflect this impact.

[0141] Among them, A 1 is the surface area of ​​the aluminum water tank 107, m 2 ;

[0142] A 2is the surface area of ​​the copper water tank 101, m 2 ;

[0143] R 1 is the radius of the aluminum water tank 107, m;

[0144] R 2 is the radius of the copper water tank 101, m;

[0145] n is an adjustment parameter, considering n=2 based on the two-dimensional surface area;

[0146] Considering that the aluminum furnace is surrounded by the copper furnace, the space weight coefficient is defined as:

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
