Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel ingot molds, and more specifically, it relates to a steel ingot mold with cooling pipes. Background Technology
[0002] Steel ingot molds are key tools used in the metallurgical industry for casting steel ingots. They are typically made of cast iron or heat-resistant steel, possessing excellent high-temperature resistance and wear resistance. Their structure usually includes a mold body and a mold base. The mold body is a vertical, barrel-shaped or ingot-shaped cavity to facilitate the shaping of molten steel after pouring in. In the field of steel ingot casting, the cooling effect of the ingot mold plays a decisive role in the quality of the steel ingot and production efficiency. Traditional steel ingot molds mostly employ natural cooling or simple external spray cooling methods. These methods suffer from slow and uneven cooling, making the ingots prone to defects such as shrinkage cavities and cracks, significantly impacting product quality. Furthermore, the prolonged cooling time significantly reduces production efficiency and increases production costs. Some molds with built-in cooling structures typically have fixed, internal cooling pipes. If blockages or damage occur, repairs require complete mold disassembly, which is difficult, time-consuming, and costly.
[0003] Therefore, in order to solve the above-mentioned technical problems, this application proposes a steel ingot mold with cooling pipes. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel ingot mold with cooling pipes.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel ingot mold with cooling pipes, comprising a mold body, wherein the mold body is divided into a partition layer arranged around the forming cavity, the partition layer is filled with a low-temperature heat-conducting liquid, and a detachable surrounding cooling pipe is connected to the partition layer, the surrounding cooling pipe being used to introduce a cooling medium to remove the heat of the low-temperature heat-conducting liquid.
[0006] Preferably, the top of the partition is open, and a cover plate is provided at the opening. The surrounding cooling pipe is located at the bottom of the cover plate, and the water inlet pipe at the top of the surrounding cooling pipe passes through the cover plate and extends out from the top of the cover plate. The water outlet pipe of the surrounding cooling pipe exits from the bottom of the mold body.
[0007] Preferably, the bottom end of the mold body is connected to a connecting pipe through which the water outlet pipe passes, and the inside of the connecting pipe is provided with an annular rubber to seal the water outlet pipe area.
[0008] Preferably, vertical rods are fixedly connected to the four corners of the bottom of the mold body, and a base is welded to the bottom of the vertical rod, with a buffer pad installed at the bottom of the base.
[0009] Preferably, screws are installed on both sides of the top of the mold body, mounting plates are fixedly connected to both sides of the cover plate, and through holes for the screws to pass through are opened inside the mounting plates. Nuts are threaded onto the outer side wall of the screws.
[0010] Preferably, the top of the mold body has frame-shaped grooves on both the inner and outer sides of the partition, and the bottom of the cover plate is fixedly connected to a frame-shaped plate corresponding to the frame-shaped grooves and covered with rubber.
[0011] Preferably, the upper and lower sides of the surface of the mold body are respectively equipped with heat-conducting liquid pipes with valves for the discharge and input of heat-conducting liquid.
[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model achieves heat exchange between the pipe wall and the low-temperature heat-conducting liquid inside the partition, rapidly removing the heat absorbed by the low-temperature heat-conducting liquid and forming an efficient heat transfer path. Since the surrounding cooling pipe is detachable, it can be easily disassembled for cleaning or replacement when blockages or damage occur, avoiding the drawbacks of traditional built-in cooling channels that require complete mold disassembly. At the same time, the surrounding layout ensures that the low-temperature heat-conducting liquid in each part of the partition can fully contact the cooling pipe, achieving uniform cooling, thus solving the problems of uneven cooling, low efficiency, and fixed built-in design of traditional cooling methods in the background technology. 2. This utility model ensures the sealing and reliability of the entire cooling system through a rubber-coated frame plate and a sealing structure with annular rubber embedded in the connecting pipe. 3. In this utility model, the upper and lower sides of the surface of the mold body are respectively equipped with heat transfer fluid pipes with valves for the discharge and input of heat transfer fluid. In this way, the replacement of low temperature heat transfer fluid does not require opening the cover plate, which improves the convenience of use. 4. In this utility model, the buffer pad can effectively cushion the impact when the hoisting equipment lowers the mold body to the ground, thus preventing damage to the bottom of the mold body.

[0015] like Figure 1-5 As shown, this utility model provides a steel ingot mold with a cooling pipe, including a mold body 1. The mold body 1 is divided into a partition 102 arranged around the forming cavity 101. The partition 102 is filled with a low-temperature heat-conducting liquid (such as deionized water, heat-conducting oil, etc.). A surrounding cooling pipe 2 is detachably connected to the partition 102. The surrounding cooling pipe 2 is used to introduce a cooling medium to remove the heat of the low-temperature heat-conducting liquid.
[0016] During operation, after molten steel is injected into the forming cavity 101 of the mold body 1, the resulting large amount of heat is transferred to the partition layer 102. The low-temperature heat-conducting liquid filled in the partition layer 102, with its excellent thermal conductivity, quickly absorbs the heat transferred from the forming cavity 101, achieving initial heat conduction and diffusion. The surrounding cooling pipes 2 are arranged tightly against the partition layer 102. When the cooling medium (coolant) enters the surrounding cooling pipes 2, it exchanges heat with the low-temperature heat-conducting liquid in the partition layer 102 through the pipe wall, rapidly carrying away the heat absorbed by the low-temperature heat-conducting liquid, forming an efficient heat transfer path. Because the surrounding cooling pipes 2 are detachable, they can be easily disassembled for cleaning or replacement in case of blockage or damage, avoiding the drawbacks of traditional built-in cooling channels that require complete mold disassembly. Simultaneously, the surrounding layout ensures that the low-temperature heat-conducting liquid in all parts of the partition layer 102 can fully contact the cooling pipes, achieving uniform cooling. This effectively solves the problems of uneven cooling and low efficiency in traditional cooling methods, reducing the probability of defects such as shrinkage cavities and cracks in steel ingots, and improving product quality and production efficiency.
[0017] The top of the partition 102 is open, and a cover plate 3 is provided at the opening. The surrounding cooling pipe 2 is located at the bottom of the cover plate 3, and the liquid inlet pipe 201 at the top of the surrounding cooling pipe 2 passes through the cover plate 3 and extends out from the top of the cover plate 3. The liquid outlet pipe 202 of the surrounding cooling pipe 2 passes through the bottom of the mold body 1. The bottom of the mold body 1 is connected to a connecting pipe 5 through which the liquid outlet pipe 202 passes, and the inside of the connecting pipe 5 is provided with an annular rubber 6 to support the liquid outlet pipe. The 202 part is sealed. Screws 10 are installed on both sides of the top of the mold body 1. Mounting plates 11 are fixedly connected to both sides of the cover plate 3. The mounting plates 11 have through holes 12 for the screws 10 to pass through. Nuts are threaded on the outer side of the screws 10. The top of the mold body 1 has frame-shaped grooves 103 on both the inner and outer sides of the partition 102. The bottom of the cover plate 3 is fixedly connected to a frame plate 13 corresponding to the frame-shaped grooves 103 and covered with rubber.
[0018] After molten steel is injected into the molding cavity 101, heat is transferred through the cavity wall to the low-temperature heat-conducting liquid in the partition 102. The cover plate 3 at the top of the partition 102 is tightly pressed onto the mold body 1 by the cooperation of the mounting plate 11, the screw 10, and the nut (that is, the through hole 12 on the mounting plate 11 is aligned with the screw 10 and inserted. After insertion, the nut is rotated clockwise to install the nut on the screw 10. The nut moves downward along the screw 10 and slowly abuts against the top of the cover plate 3, thereby installing the cover plate 3 at the top of the mold body 1). The frame plate 13 and the rubber on it are tightly fitted with the frame groove 103 to achieve the sealing of the partition 102 and prevent the low-temperature heat-conducting liquid from leaking. The inlet pipe 201 of the surrounding cooling pipe 2 extends from the top of the cover plate 3 and connects to an external cooling medium source. After the cooling medium flows into the surrounding cooling pipe 2, it exchanges heat with the low-temperature heat transfer fluid during its flow within the pipe. After absorbing heat, it is discharged through the outlet pipe 202. The outlet pipe 202 passes through the connecting pipe 5 at the bottom of the mold body 1. The annular rubber 6 inside the connecting pipe 5 seals the outlet pipe 202 (after the outlet pipe 202 passes through the connecting pipe 5, it squeezes the annular rubber 6 inside the connecting pipe 5, forming a sealing surface through interference fit, thereby sealing this part), preventing the low-temperature heat transfer fluid from leaking out from here. With this structure, the cooling medium can efficiently remove the heat from the low-temperature heat transfer fluid, achieving rapid cooling of the molten steel. At the same time, when it is necessary to repair or replace the surrounding cooling pipe 2, simply unscrew the nut and remove the cover plate 3 to remove the entire surrounding cooling pipe 2 from the partition 102, making the operation simple and quick. The sealing structure of the rubber-coated frame plate 13 and the connecting pipe 5 with the embedded annular rubber 6 ensures the sealing and reliability of the entire cooling system.
[0019] Furthermore, heat transfer fluid pipes 4 equipped with valves are installed on the upper and lower sides of the surface of the mold body 1 for the discharge and input of heat transfer fluid. This eliminates the need to open the cover plate 3 to replace the low-temperature heat transfer fluid, improving ease of use. Vertical rods 7 are fixedly connected to the four corners of the bottom of the mold body 1, and bases 8 are welded to the bottom of the vertical rods 7. The vertical rods 7 support the bottom of the mold body 1 to provide space for the connection of the liquid outlet pipe 202 with other pipes. A buffer pad 9 is installed at the bottom of the base 8. The buffer pad 9 can effectively cushion the impact when the hoisting equipment lowers the mold body 1 to the ground to prevent damage to the bottom of the mold body 1.
