Description

Technical Field

[0001] This invention relates to the field of casting technology, and specifically to a continuous casting molding apparatus for anode material precursors. Background Technology

[0002] Anode material precursors are key raw materials for battery anode materials, and their quality directly affects the battery's energy density, cycle life, and safety performance. With the rapid development of new energy vehicles and the energy storage industry, the market demand for anode material precursors continues to grow, placing higher demands on the uniformity of chemical composition, particle morphology regularity, and internal microstructure density of the products. Continuous casting is an important process for producing such precursors. Its basic principle is to continuously pour molten metal into a crystallizer, where it solidifies on the inner wall to form a solidified shell of a certain thickness. The solidified billet is then continuously pulled out by a straightening machine and subsequently cut to obtain a cast billet with the desired cross-sectional shape. Compared with conventional die casting, continuous casting has advantages such as high production efficiency, high metal yield, and dense billet microstructure, making it the preferred process for large-scale precursor production.

[0003] However, traditional continuous casting equipment suffers from the following technical problems in actual production: the cooling structure of the crystallizer is mostly a single-layer water jacket. When the cooling water flows in a single large-section channel, it tends to follow the shortest path, forming dead water zones or slow-flow zones within the channel. This results in uneven heat transfer intensity in the circumferential and axial directions of the copper tube, and also affects the uniformity of the billet shell thickness. In addition, impurities carried in the cooling water and the precipitated scale easily deposit and adhere to the outer wall of the copper tube. The scale layer significantly reduces heat transfer efficiency due to its thermal resistance, further exacerbating the uneven heat transfer. Furthermore, to prevent the initial billet shell from sticking to the inner wall of the crystallizer, the crystallizer needs to be vibrated to promote demolding. Conventional vibration mechanisms mostly use a motor-driven eccentric wheel to achieve mechanical vibration. Its vibration transmission path is relatively long—from the drive source through the reducer, eccentric shaft, connecting rod to the vibration table. The gaps and elastic deformations of each link cause vibration energy attenuation, causing the actual vibration parameters transmitted to the copper tube to deviate from the set value, affecting the stability of the demolding effect.

[0004] Therefore, it is necessary to provide a continuous casting molding apparatus for negative electrode material precursors to solve the above problems. Summary of the Invention

[0005] To solve the above problems, the present invention provides the following technical solution: a continuous casting molding device for anode material precursors, comprising a ladle, an tundish, a base, a crystallizer mechanism, and a straightening machine. The ladle is disposed on a ladle rotary table for feeding the tundish. Two sets of swaying components are disposed on the base for swaying the tundish. The crystallizer mechanism is disposed below the tundish, and the straightening machine is disposed below the crystallizer mechanism. The crystallizer mechanism includes:

[0006] Copper pipe;

[0007] The outer cylinder is fitted over the outside of the copper tube;

[0008] A partition cylinder is fitted over the outside of the copper tube and located inside the outer cylinder. The partition cylinder and the copper tube form a first space, and the partition cylinder and the outer cylinder form a second space.

[0009] The inlet pipe and the outlet pipe are respectively connected to the first space;

[0010] The first space is configured to continuously supply cooling liquid through the inlet pipe and the outlet pipe to achieve cooling, and the second space is configured to selectively control the temperature based on the internal liquid temperature.

[0011] Furthermore, as a preferred embodiment, the second space is configured to replace the liquid inside when the internal liquid temperature exceeds a temperature threshold and continues to rise, thereby restoring the liquid temperature to a standard value.

[0012] Furthermore, as a preferred embodiment, the second space is configured such that when the rate of change of the internal liquid temperature exceeds a rate of change threshold and the rate of change indicates a temperature rise, the liquid therein is replaced to restore the liquid temperature to a standard value.

[0013] Furthermore, as a preferred embodiment, the volume of the first space is 1 / 15 to 1 / 5 of the volume of the second space.

[0014] Furthermore, as a preferred embodiment, the partition cylinder has multiple holes, and a vibration mechanism is installed in each hole; a piston plate is slidably disposed in the second space, and the piston plate is driven by a telescopic cylinder to hydraulically drive the vibration mechanism to vibrate the copper tube.

[0015] Furthermore, preferably, the vibration mechanism includes:

[0016] A sleeve has a shoulder at one end, which is pressed against one side of the cavity of the partition cylinder by a sealing ring, and the other end of the sleeve is locked to the other side of the cavity by a locking ring;

[0017] A cylindrical piston is slidably disposed in the sleeve. One end of the cylindrical piston forms a vibrating rod, and the other end of the cylindrical piston is fixed with a connecting rod. An elastic element connects the connecting rod and the sleeve.

[0018] Furthermore, preferably, in the initial state, the end of the cylindrical piston near the second space is retracted into the sleeve.

[0019] Furthermore, as a preferred embodiment, a connector is provided below the base, the connector having a height adjustment end, the height adjustment end being connected to the copper tube via a connecting seat.

[0020] Compared with the prior art, the present invention provides a continuous casting molding apparatus for anode material precursors, which has the following beneficial effects:

[0021] First, the present invention achieves zoned cooling of the crystallizer by setting up a double-layer nested structure of copper tube, partition cylinder and outer cylinder, forming a first space between the copper tube and partition cylinder and a second space between the partition cylinder and outer cylinder. The first space is continuously supplied with cooling liquid through the liquid inlet pipe and liquid outlet pipe to achieve rapid cooling and reduce scale deposition; the second space selectively controls the temperature based on the internal liquid temperature and replaces the liquid in time when the temperature is abnormal to ensure the stability of the cooling capacity.

[0022] Secondly, by opening holes in the partition cylinder and installing a vibration mechanism, the present invention utilizes the piston plate and telescopic cylinder in the second space to generate hydraulic driving force, which directly drives the vibration mechanism to vibrate the copper tube. Compared with the traditional mechanical eccentric vibration structure, this hydraulic driving method has a shorter vibration transmission path and less energy loss.

[0023] Third, the present invention achieves proactive protection of cooling capacity by setting a dual monitoring mechanism of temperature threshold and rate of change threshold in the second space, which monitors both the absolute temperature of the liquid and the trend and rate of temperature change.

It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0030] Example: Please refer to Figures 1 to 4 This embodiment provides a continuous casting and forming device for anode material precursors, mainly comprising a ladle 1, a ladle rotary table 2, an tundish 3, a base 4, a swaying assembly 5, a connector 6, a connecting seat 7, a crystallizer mechanism 8, and a straightening machine 9. The ladle 1 is mounted on the ladle rotary table 2 and is used to hold the melt, with multiple ladles being alternately fed through the rotation of the ladle rotary table 2. The tundish 3 is located below the ladle 1, receiving the melt from the ladle 1 and stabilizing and distributing it. Two sets of swaying assemblies 5 are mounted on the base 4, located on either side of the tundish 3, for swaying the tundish 3 to uniformly distribute the melt temperature and composition. The crystallizer mechanism 8 is located below the tundish 3, and the melt flows from the bottom of the tundish 3 into the copper tube 81 of the crystallizer mechanism 8 to solidify. The straightening machine 9 is located below the crystallizer mechanism 8 and is used to pull the solidified billet downwards and straighten it.

[0031] The working process of the device of the present invention is as follows: First, the ladle 1 is moved above the tundish 3 under the support of the ladle rotundum 2, and the melt is poured into the tundish 3. During the pouring process, two sets of shaking components 5 drive the tundish 3 to shake regularly, so that the temperature and composition of the melt tend to be uniform. Subsequently, the melt flows from the immersion nozzle at the bottom of the tundish 3 into the copper tube 81 of the crystallizer mechanism 8, and solidifies under the cooling effect of the inner wall of the copper tube 81 to form a solidified shell of a certain thickness. During the solidification process, cooling liquid is continuously introduced into the first space of the crystallizer mechanism 8 to achieve rapid cooling, and the second space selectively controls the temperature based on the internal liquid temperature. At the same time, the vibration mechanism 84 vibrates the copper tube 81 under hydraulic drive to prevent the billet from sticking to the inner wall of the copper tube 81. Finally, the straightening machine 9 continuously pulls the solidified billet out from under the copper tube 81, and after straightening, it enters the subsequent cutting process.

[0032] Specifically, ladle 1 is a container for holding the precursor melt, and its interior is equipped with heating and insulation devices to maintain the melt temperature near the pouring temperature. Ladle 1 is positioned on ladle turret 2, a load-bearing device that can rotate around a vertical axis. It typically has two ladle positions: one at the pouring position (located above the tundish 3), and the other as a standby or unloading position. After the melt in ladle 1 is poured, ladle turret 2 rotates, transferring the full ladle to the pouring position, achieving continuous feeding. The placement of ladle turret 2 ensures a stable melt level within the tundish 3, providing stable molten steel supply conditions for continuous casting.

[0033] The tundish 3 is located below the ladle 1 and above the crystallizer mechanism 8, serving as an intermediate container connecting the ladle 1 and the crystallizer mechanism 8. The main functions of the tundish 3 include: receiving the molten material poured from the ladle 1, reducing the flow rate and turbulence of the melt; stabilizing the melt level to provide a stable flow rate for the crystallizer; and promoting the flotation and separation of non-metallic inclusions in the melt. The bottom of the tundish 3 is equipped with an immersion nozzle through which the molten material flows into the copper tube 81 of the crystallizer mechanism 8.

[0034] Two sets of swaying components 5 are installed on the base 4, located on both sides of the tundish 3, for swaying the tundish 3. The swaying components 5 can be linear drive elements such as hydraulic cylinders, pneumatic cylinders, or electric push rods, alternately pushing the two sides of the tundish 3 to produce a regular swaying motion. The swaying of the tundish 3 promotes the homogenization of temperature and composition inside the melt, reduces temperature gradients and compositional segregation, and facilitates the flotation of inclusions, thereby improving the internal quality of the cast billet. The symmetrical arrangement of the two sets of swaying components 5 ensures the force balance and motion stability of the tundish 3 during swaying.

[0035] like Figure 3 As shown, the crystallizer mechanism 8 is located below the tundish 3 and is used to solidify the melt therein. The crystallizer mechanism 8 includes a copper tube 81, an outer cylinder 82, a partition cylinder 83, a vibration mechanism 84, an inlet pipe 85, an outlet pipe 86, a piston plate 87, and a telescopic cylinder 88.

[0036] The copper tube 81 is the core component of the crystallizer mechanism 8, where the molten metal solidifies. The copper tube 81 is made of a copper alloy with excellent thermal conductivity, and its inner wall is polished to reduce friction between the cast billet and the inner wall of the copper tube 81. An outer cylinder 82, made of steel, is fitted around the copper tube 81 to withstand the pressure of the cooling liquid and provide overall rigid support. A partition cylinder 83 is fitted around the copper tube 81 and located inside the outer cylinder 82, i.e., the partition cylinder 83 is located between the copper tube 81 and the outer cylinder 82. The space between the partition cylinder 83 and the copper tube 81 forms a first space, and the space between the partition cylinder 83 and the outer cylinder 82 forms a second space. By setting the partition cylinder 83, the space between the copper tube 81 and the outer cylinder 82 is divided into two independent cooling chambers, achieving zoned cooling.

[0037] The inlet pipe 85 and outlet pipe 86 are connected to the first space to continuously supply cooling liquid to it. During operation, the cooling liquid flows into the first space from the inlet pipe 85, absorbs heat along the outer wall of the copper tube 81, and then flows out from the outlet pipe 86, achieving continuous cooling. The flow rate of the cooling liquid in the first space is determined by the diameter of the inlet pipe 85 and the outlet pipe 86, as well as the supply pressure. Adjusting the flow rate controls the cooling intensity of the copper tube 81. Because the first space is in close contact with the outer wall of the copper tube 81, the cooling liquid can directly and quickly remove the heat released during the solidification of the melt, ensuring the rapid formation of the solidified shell.

[0038] The second space is configured for selective temperature control based on the temperature of its internal liquid. The second space is filled with a liquid (such as cooling water or a dedicated coolant), which acts as a temperature buffer under normal operating conditions, absorbing heat conducted through the partition 83 from the first space, thus aiding in cooling and temperature stabilization. When the liquid temperature in the second space exceeds a temperature threshold and continues to rise, it indicates that the liquid's cooling capacity has significantly decreased and is continuously deteriorating. At this point, the liquid in the second space is replaced to restore the liquid temperature to the standard value and restore its cooling buffer capacity. This selective temperature control method avoids the problem of loss of cooling capacity due to a continuous increase in the liquid temperature in the second space, ensuring the long-term operational stability of the crystallizer mechanism 8.

[0039] Furthermore, when the rate of change of liquid temperature in the second space exceeds the rate of change threshold and the rate of change represents a temperature rise, it indicates that the liquid temperature is rising rapidly. Even if the current absolute temperature has not yet exceeded the temperature threshold, it foreshadows that the cooling capacity will soon be insufficient. In this case, replacing the liquid in advance provides proactive protection for the cooling capacity and avoids fluctuations in the quality of the cast billet due to a lag in temperature response.

[0040] Preferably, the volume of the first space is 1 / 15 to 1 / 5 of the volume of the second space. Within this volume ratio range, the radial cross-section of the first space is much smaller than the large cross-section flow channel of a traditional single-layer water jacket. The coolant is confined to a narrow annular channel, and the flow cross-section remains uniform along the circumference and axial direction. This structurally eliminates the geometric conditions caused by dead water zones and slow flow zones, significantly increasing the flow velocity and turnover frequency of the coolant, enabling rapid and uniform heat exchange on the copper tube 81. Simultaneously, the higher flow velocity creates a continuous scouring effect on the outer wall of the copper tube 81, effectively inhibiting the deposition and adhesion of impurities and scale, and reducing the impact of scale thermal resistance on heat transfer efficiency. The second space has a relatively large volume, accommodating sufficient auxiliary coolant heat capacity, providing a stable temperature buffer during selective temperature control, and preventing a sudden rise in liquid temperature within the second space due to external heat load fluctuations.

[0041] If the volume of the first space is less than 1 / 15 of the volume of the second space, the cross-section of the first space is too small, the coolant flow is insufficient, and it cannot remove enough heat, so the cooling rate cannot meet the primary cooling requirements. If the volume of the first space is greater than 1 / 5 of the volume of the second space, the cross-section of the first space is too large, the flow rate decreases, and dead water zones and slow flow zones will reappear. The aforementioned uneven heat exchange and scaling problems will reappear. At the same time, the volume of the second space is too small, and the heat capacity is insufficient to provide an effective temperature buffer.

[0042] like Figure 4 As shown, the vibration mechanism 84 is installed in a hole in the partition cylinder 83 to vibrate the copper tube 81 to prevent the cast billet from sticking to the inner wall of the copper tube 81. Multiple holes are provided on the partition cylinder 83, distributed along its circumference and axial direction, and a vibration mechanism 84 is installed in each hole. The multiple vibration mechanisms 84 work together to produce a uniform vibration effect on the copper tube 81.

[0043] The vibration mechanism 84 includes a sleeve 841, a sealing ring 842, a locking ring 843, a cylindrical piston 844, a vibration rod 845, a connecting rod 846, and an elastic element 847. The sleeve 841 passes through the bore of the partition cylinder 83. One end of the sleeve 841 has a shoulder with an outer diameter larger than the bore diameter. The shoulder is pressed against one side of the bore of the partition cylinder 83 (facing the second space) by the sealing ring 842. The sealing ring 842 forms a seal between the shoulder and the partition cylinder 83, preventing liquid in the second space from leaking through the gap between the bore and the sleeve 841. The other end of the sleeve 841 is locked to the other side of the bore (facing the first space) by the locking ring 843. The locking ring 843 is threaded or snapped onto the sleeve 841, axially fixing the sleeve 841 to the partition cylinder 83. Through the cooperation of the shoulder, sealing ring 842 and locking ring 843, the sleeve 841 is reliably fixed in the hole of the partition cylinder 83, and both sides are sealed.

[0044] A cylindrical piston 844 is slidably disposed within a sleeve 841, meaning that the outer wall of the cylindrical piston 844 and the inner wall of the sleeve 841 are in a sealed fit, allowing the cylindrical piston 844 to slide axially within the sleeve 841. A vibration rod 845 is formed at one end of the cylindrical piston 844, extending from the end of the sleeve 841 and abutting against the outer wall of the copper tube 81, used to transmit the reciprocating motion of the cylindrical piston 844 as vibration of the copper tube 81. A connecting rod 846 is fixed to the other end of the cylindrical piston 844, extending from the other end of the sleeve 841. An elastic element 847 connects the connecting rod 846 and the sleeve 841. The function of the elastic element 847 is to provide a restoring force when the cylindrical piston 844 is displaced under hydraulic pressure, causing the cylindrical piston 844 to automatically reset, thus achieving reciprocating vibration.

[0045] In the initial state, the end of the cylindrical piston 844 near the second space is retracted into the sleeve 841. That is, when not in operation, the end face of the cylindrical piston 844 does not protrude from the end face of the sleeve 841. After the end face of the cylindrical piston 844 retracts, a liquid inlet gap is formed in the sleeve 841 on the side of the cylindrical piston 844 away from the copper tube 81. The liquid medium can enter from the side of the cylindrical piston 844 away from the copper tube 81 and act on the cylindrical piston 844, which facilitates driving the cylindrical piston 844 to move towards the copper tube 81.

[0046] During operation, the piston plate 87 generates hydraulic pulses under the drive of the telescopic cylinder 88. Under pressure, the liquid medium in the second space pushes the cylindrical piston 844 to move towards the copper tube 81, overcoming the elastic force of the elastic element 847. The vibrating rod 845 strikes the outer wall of the copper tube 81, generating vibration. Subsequently, the elastic element 847 pushes the cylindrical piston 844 back to the retracted position, completing one vibration cycle.

[0047] The piston plate 87 is slidably disposed in the second space and can move axially within the second space. The piston plate 87 is driven by a telescopic cylinder 88, which is fixed to the outer cylinder 82, and the piston rod of the telescopic cylinder 88 is connected to the piston plate 87. The telescopic cylinder 88 can be a hydraulic cylinder or a pneumatic cylinder, and its telescopic movement drives the piston plate 87 to reciprocate within the second space.

[0048] When the telescopic cylinder 88 drives the piston plate 87 to move, the piston plate 87 compresses the liquid in the second space, generating hydraulic pulses. These hydraulic pulses are transmitted through the holes in the partition cylinder 83 to the sleeves 841 of each vibration mechanism 84, pushing the cylindrical piston 844 to move, which in turn vibrates the copper tube 81 through the vibrating rod 845. By controlling the extension frequency and stroke of the telescopic cylinder 88, the vibration frequency and amplitude of the copper tube 81 can be controlled. Compared with the traditional mechanical eccentric vibration structure, this hydraulic drive method has a shorter vibration transmission path and less energy loss. At the same time, the liquid in the second space has both cooling and buffering functions as well as vibration transmission, eliminating the need for an additional vibration transmission medium and simplifying the device structure.

[0049] A connector 6 is located below the base 4. The connector 6 has a height adjustment end, which is connected to the copper tube 81 via a connecting seat 7. The connector 6 is a height-adjustable connection device, and its height adjustment end can achieve height changes through threaded adjustment, hydraulic adjustment, or rack and pinion adjustment. The connecting seat 7 is a transitional connector between the height adjustment end of the connector 6 and the copper tube 81. One end of the connecting seat 7 is connected to the height adjustment end of the connector 6, and the other end is connected to the upper end of the copper tube 81.

[0050] The straightening machine 9 is located below the crystallizer mechanism 8 and is used to pull the solidified billet downwards and straighten it. The straightening machine 9 typically includes multiple sets of clamping rollers and a drive device. The clamping rollers clamp both sides of the billet, and the drive device drives the clamping rollers to rotate, thereby achieving continuous drawing of the billet.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
