Description

Technical Field

[0001] This utility model relates to the field of graphite crystallizer technology, specifically a graphite crystallizer with a cooling structure. Background Technology

[0002] A graphite crystallizer is a piece of equipment used in metal casting, primarily for the continuous casting of copper rods, copper strips, and copper tubes. Graphite crystallizers are typically made of graphite, which possesses excellent thermal conductivity, lubricity, and wear resistance. It effectively controls the cooling rate and temperature of the molten metal, thereby ensuring product quality and production efficiency.

[0003] In practical applications, graphite crystallizers require cooling. Graphite crystallizers are primarily used for the continuous casting of high-temperature copper tubes. Their working principle involves cooling the molten copper through the annular cavity between the graphite jacket and the graphite core rod, causing it to solidify into a tube blank. Therefore, to control the cooling rate and temperature of the molten copper, the cooling jacket uses circulating cooling water to cool the inner cavity.

[0004] To cool the graphite crystallizer, water channels (including channels formed by heat-conducting pipes wrapped around the crystallizer) are installed outside the crystallizer, allowing cooling water to pass through these channels to cool the crystallizer. However, current water channels are curved and located outside the crystallizer, resulting in long paths. Due to the high temperature of the crystallizer, the water in the channels is rapidly heated, significantly reducing the cooling effect. For example, a composite structure horizontal continuous casting graphite crystallizer device proposed in document number "CN118045974A" states at the end of section

[0023] that "the water-cooled copper sleeve 11 is provided with a water-cooled steel sleeve 14 on its outer side, and the inner surface of the water-cooled steel sleeve 14 is provided with a spiral water channel. The water-cooled steel sleeve 14 is fixed together with the lower pressure block 2 and the upper pressure block 12 to form the water inlet channel 3." The long length of the spiral water channel causes the cooling water to be heated as it passes through, thus reducing the cooling effect. Therefore, we propose a graphite crystallizer with a cooling structure. Utility Model Content

[0005] This invention provides a graphite crystallizer with a cooling structure, which has the advantage of rapid cooling and heat dissipation of the crystallizer, and solves the problems mentioned in the background art.

[0006] The technical solution of this utility model is implemented as follows: a graphite crystallizer with a cooling structure includes a graphite sleeve, the surface of which is provided with two arc-shaped heat-conducting plates, and the surface of each arc-shaped heat-conducting plate is provided with several heat exchange tubes, the two ends of which are respectively connected to the mounting pipe.

[0007] Preferably, both ends of the heat exchange tube are provided with connecting pipes, which are connected to the mounting tube.

[0008] Preferably, the graphite sleeve surface is provided with an installation groove, and the arc-shaped heat-conducting plate is placed in the installation groove.

[0009] Preferably, both arc-shaped heat-conducting plates have connecting edges, which can be detachably connected.

[0010] Preferably, a plug is provided at one end of the graphite sleeve, a core is provided inside the graphite sleeve, the core is coaxially connected to the plug, a crystallization cavity is formed between the core and the graphite sleeve, and the plug is provided with multiple inlets communicating with the crystallization cavity.

[0011] Compared with the prior art, in use, the coolant automatically enters each heat exchange tube after entering the installation pipe. The coolant enters from one end of the heat exchange tube and flows out from the other end. The coolant only flows through half the circumference of the graphite sleeve surface. This allows the coolant to flow through the graphite sleeve surface in a shorter time, so the coolant in the heat exchange tube has a better cooling effect. This avoids the problem of traditional cooling pipes being wrapped around the crystallizer for a long time, which causes the coolant to be heated by the crystallizer and reduces the cooling effect.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1 to 6 This utility model provides a technical solution: a graphite crystallizer with a cooling structure, including a graphite sleeve 1, such as... Figure 1 As shown, a plug 11 is provided inside one end of the graphite sleeve 1, and a core 6 is provided inside the graphite sleeve 1. The core 6 and the plug 11 are coaxially connected, forming a crystallization cavity 7 between the core 6 and the graphite sleeve 1. The plug 11 has multiple inlets 8 that communicate with the crystallization cavity 7. It should be noted that both the core 6 and the plug 11 are graphite supports. In actual use, external molten metal enters into the crystallization cavity 7 through the inlets 8, and the molten metal crystallizes during the flow.

[0022] In this application, in order to allow the heat on the surface of the graphite crystallizer to dissipate quickly, such as Figure 1 and Figure 2 As shown, two arc-shaped heat-conducting plates 2 are provided on the surface of the graphite sleeve 1, such as... Figure 3 As shown, an installation groove 9 is provided on the surface of the graphite sleeve 1. The size and shape of the installation groove 9 are matched with the arc-shaped heat-conducting plate 2. During installation, the two arc-shaped heat-conducting plates 2 are placed in the installation groove 9, and the two arc-shaped heat-conducting plates 2 just cover the installation groove 9.

[0023] The arc-shaped heat-conducting plate 2 is a heat-conducting plate such as a steel plate or a copper plate. Each arc-shaped heat-conducting plate 2 has several heat exchange tubes 3 on its surface. The two ends of the heat exchange tubes 3 are respectively connected to the mounting tubes 4. Specifically, the two ends of the heat exchange tubes 3 are provided with connecting tubes 5, so that the ends of the connecting tubes 5 are connected to the mounting tubes 4.

[0024] Specifically, the mounting slot 9 is wrapped by two arc-shaped heat-conducting plates 2, each of which corresponds to a heat dissipation structure. Therefore, there are two heat dissipation structures for the graphite sleeve 1 in this application. In actual use, the two heat dissipation structures are vented or energized with coolant (which can be water). The following will focus on coolant in detail.

[0025] Specifically, coolant is introduced into the two mounting pipes 4 on the same side. After entering the mounting pipes 4, the coolant automatically flows into each heat exchange pipe 3. Since the heat exchange pipes 3 are arranged at intervals along the arc-shaped heat-conducting plate 2, the arc-shaped heat-conducting plate 2 becomes a surface that absorbs heat. Moreover, the coolant enters from one end of the heat exchange pipe 3 and flows out from the other end, with the coolant only flowing through half the circumference of the graphite sleeve 1. In actual use, a pump is used to introduce coolant into the two mounting pipes 4 on the same side at a certain pressure, and then a pipe is used to collect the coolant from the two mounting pipes 4 on the other side. Because the coolant has a certain pressure, it can flow at a certain speed in each heat exchange pipe 3, avoiding prolonged stagnation on the surface of the graphite sleeve 1. Since the heat exchange pipes 3 are laid in a semi-circular shape on the surface of the graphite sleeve 1, the coolant flows through the surface of the graphite sleeve 1 in a shorter time, resulting in good cooling effect and rapid removal of heat from the surface of the graphite sleeve 1.

[0026] Based on the above embodiments, further optimization is possible. The edges of the two arc-shaped heat-conducting plates 2 are provided with connecting edges 10, and the connecting edges 10 are detachably connected to each other. Specifically, the two are fastened together by bolts.

[0027] Based on the above embodiments, it should be further explained that the heat exchange tube 3 and the arc-shaped heat conduction plate 2 are welded together as a whole, so that the contact area between the two is larger and heat can be transferred quickly.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
