Description

Technical Field

[0001] This utility model provides a graphite platform mechanism for a copper ingot casting furnace, belonging to the field of high-temperature industrial electric furnace technology. Background Technology

[0002] In the industrial production of oxygen-free copper, ingots are typically cast first, followed by transportation and processing. Traditional oxygen-free copper ingot casting involves natural cooling during crystallization, with solidification occurring from top to bottom. This results in a temperature gradient from the periphery to the core of the ingot; the periphery cools faster and is at a lower temperature, while the core cools more slowly and is at a higher temperature. This causes an inverted conical liquid pool to form on the surface of the ingot after cooling, significantly reducing its utilization rate. Therefore, designing a graphite platform assembly for a homogenizing water-cooled plate in a copper ingot casting furnace is essential to effectively solve the liquid pool problem. A complete graphite platform assembly for a copper ingot casting furnace is not only a crucial prerequisite for efficient oxygen-free copper ingot casting but also a necessary guarantee for large-scale oxygen-free copper production. Utility Model Content

[0003] To address the technical problem of poor cooling effect of graphite platform mechanisms in the casting of oxygen-free copper ingots during the casting process, this utility model proposes a graphite platform mechanism for copper ingot furnaces. The aim is to improve the cooling effect of oxygen-free copper ingots by improving the hardware structure of the graphite platform mechanism for copper ingot furnaces.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a graphite platform mechanism for a copper ingot casting furnace, including a graphite carrying platform and a graphite heat transfer platform. A first groove is provided on the graphite carrying platform, which fits into the boss of the graphite heat transfer platform. A first heat insulation component is provided between the base of the graphite heat transfer platform and the graphite carrying platform. The first heat insulation component is in clearance fit with the boss. The boss and the base form an integral structure. Several second grooves are provided on the end of the base away from the boss.

[0005] A second heat insulation component is provided at the end of the first heat insulation component away from the graphite stage, and the second heat insulation component is fitted with the base with a clearance.

[0006] The graphite heat transfer stage is provided with a hollow sandwich structure water-cooling plate at one end away from the graphite carrier stage. The water-cooling plate has a number of first through holes and a number of second through holes, and the multiple first through holes correspond one-to-one with the second grooves.

[0007] A first graphite column is fitted into the first through hole with a clearance fit, and one end of the first graphite column is fitted into the second groove with a clearance fit.

[0008] A support column is fitted inside the second through hole with a gap, and one end of the support column abuts against the graphite heat transfer table.

[0009] Furthermore, the water-cooling plate is provided with a second air inlet and several coolant inlets, and the second air inlet is coaxially arranged with the first air inlet on the graphite heat transfer platform.

[0010] Furthermore, the first heat insulation component includes several heat insulation plates, which are connected end to end to form a square frame structure. The inner sidewall of the frame structure cooperates with the outer sidewall of the boss.

[0011] Furthermore, the second heat insulation component includes several heat insulation strips, which are connected end to end to form a square frame structure. The inner wall of the frame structure cooperates with the outer wall of the base.

[0012] Furthermore, a first gasket is provided at the end of the first graphite column away from the second groove.

[0013] Furthermore, each end of the first graphite column has an integrally formed first protrusion, with the first protrusion at one end cooperating with the second groove, and the first gasket is installed on the first protrusion at the other end of the first graphite column.

[0014] Furthermore, a second gasket is provided at the end of the support column away from the graphite heat transfer table.

[0015] Furthermore, the end of the support column away from the graphite heat transfer platform is integrally formed with a second protrusion, and a second gasket is installed on the second protrusion.

[0016] The advantages of this utility model over the prior art are as follows:

[0017] This invention, through the cooperation of a graphite heat transfer table, a water cooling plate, a first heat insulation component, and a second heat insulation component, enables copper ingots to cool down from the center during cooling, thus avoiding the formation of liquid pooling.

[0018] This invention effectively prevents the heat transferred from the bottom of the copper ingot to the graphite heat transfer table from dissipating to the surroundings through the second heat insulation component, greatly ensuring the cooling effect of the bottom of the copper ingot and ensuring the uniformity of the cooling of the copper ingot.

[0019] This utility model uses the cooperation of the first graphite column and the support column to jointly support the graphite stage. Under the action of the first shim and the second shim, the stability of the graphite stage is improved, thereby ensuring the safe and stable operation of the copper ingot furnace.

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] like Figures 1 to 18 As shown, this utility model provides a graphite platform mechanism for a copper ingot casting furnace, including a square graphite platform 1 and a square graphite heat transfer platform 4. A square first groove 8 is formed on the graphite platform 1 for placing the copper ingot crucible. The first groove 8 fits into the protrusion 11 of the graphite heat transfer platform 4. A heat-insulating and high-temperature-resistant first heat insulation component 2 is fixedly connected between the base 12 of the graphite heat transfer platform 4 and the graphite platform 1. The first heat insulation component 2 is clearance-fitted with the protrusion 11. Specifically, the first heat insulation component 2 includes four heat insulation plates 10, which are connected end-to-end to form a square frame structure. The inner sidewall of the first heat insulation component 2 fits into the outer sidewall of the protrusion 11.

[0043] The boss 11 and the base 12 form an integral structure. The boss 11 is located above the base 12. Several second grooves 13 are provided on the end of the base 12 away from the boss 11. In this embodiment, three second grooves 13 are provided.

[0044] A second heat insulation component 3 is fixedly connected to the end of the first heat insulation component 2 away from the graphite stage 1. The second heat insulation component 3 is clearance-fitted with the base 12. Specifically, the second heat insulation component 3 includes four heat insulation strips 9, which are connected end to end to form a square frame structure. The inner sidewall of this frame structure cooperates with the outer sidewall of the base 12. The outer sidewall of the second heat insulation component 3, the outer sidewall of the first heat insulation component 2, and the outer sidewall of the graphite stage 1 are located in the same plane.

[0045] A hollow, sandwich-structured water-cooled plate 7 is fixedly connected to one end of the graphite heat transfer stage 4 away from the graphite platform 1. The water-cooled plate 7 has several first through holes 15 and several second through holes 16. Each of the first through holes 15 corresponds to a second groove 13. In this embodiment, the water-cooled plate 7 has three first through holes 15 and four second through holes 16. The water-cooled plate 7 has a square structure and is fitted with a second heat insulation component 3 with a clearance. The second heat insulation component 3 effectively prevents the heat transferred from the bottom of the copper ingot to the graphite heat transfer stage 4 from dissipating to the surroundings, greatly ensuring the cooling effect at the bottom of the copper ingot and guaranteeing the uniformity of cooling.

[0046] Each first through hole 15 is fitted with a first graphite column 6 with clearance. One end of the first graphite column 6 passes through the first through hole 15 and is fitted with the second groove 13 with clearance.

[0047] Each second through hole 16 has a support column 5 with clearance fitting. After passing through the second through hole 16, the support column 5 abuts against the lower end face of the graphite heat transfer table 4. That is, one end of the support column 5 passes through the second through hole 16 and abuts against the end of the base 12 away from the boss 11.

[0048] The water-cooled plate 7 has a second air inlet 17 and two coolant inlets 18. The second air inlet 17 is coaxially arranged with the first air inlet 14 on the graphite heat transfer platform 4. The two coolant inlets 18 work together to allow the coolant injected into the water-cooled plate 7 to circulate in the water-cooled plate 7, thereby circulating and cooling the graphite heat transfer platform 4, allowing the copper ingot to gradually solidify from bottom to top, thus effectively avoiding the formation of liquid pooling.

[0049] The first graphite column 6 has a first protrusion integrally formed at both ends. The first protrusion at one end cooperates with the second groove 13, and a first shim is installed on the first protrusion at the other end. By adjusting the first shim, the first graphite column 6 can stably support the graphite stage 1.

[0050] The end of the support column 5 away from the graphite heat transfer table 4 has a second protrusion integrally formed, and a second shim is installed on the second protrusion. By adjusting the second shim, it is ensured that the support column 5 can stably support the graphite stage 1.

[0051] The working principle of this utility model:

[0052] When heating and casting copper ingots in a copper ingot furnace, heaters are installed at the top and sides of the furnace. The graphite platform assembly for the copper ingot furnace of this invention consists of a graphite stage 1, a graphite heat transfer stage 4, and a water-cooled plate 7 from top to bottom. The graphite stage 1, graphite heat transfer stage 4, and water-cooled plate 7 form a layered structure. By injecting coolant into the water-cooled plate 7 for circulation, the graphite heat transfer stage 4 can be cooled, accelerating the heat dissipation efficiency of the graphite heat transfer stage 4, thereby improving the cooling effect of the graphite stage 1. The first heat insulation component 2 and the second heat insulation component 3 of the graphite heat transfer stage 4 and the water-cooled plate 7 work together to allow the copper ingot to cool from the center, avoiding the formation of liquid pooling, improving the production efficiency of oxygen-free copper and the utilization rate of copper ingots.
