Description

Technical Field

[0001] The invention relates to the technical field of copper rod production, in particular to a casting device for copper rod production. Background Art

[0002] The continuous casting technology of copper products has a history of more than 30 years in my country. At present, steel belt wheel continuous casting machines are widely used for continuous casting of copper products, especially continuous casting of copper rods. Steel belt wheel continuous casting machines usually include a steel belt, a steel belt wheel, and a crystallization wheel. The steel belt passes through the crystallization wheel and multiple steel belt wheels in turn and returns to the crystallization wheel. The steel belt is guided, tightened and tightly attached to the crystallization wheel by multiple steel belt wheels. The outer edge of the crystallization wheel is closed by the steel belt to form a cavity extending from the casting port to the billet outlet along the circumference of the crystallization wheel. After the molten metal is injected from the casting port, it is forced to cool and crystallize in the cavity to form a cast billet, which is then pulled out from the billet outlet.

[0003] Traditional equipment typically utilizes a fixed ladle and crystallization wheel, adjusting the molten copper flow rate through a single tilt angle. This makes it difficult to adapt to the flow requirements of different casting stages. The pouring nozzle (such as a ceramic tube) is often set vertically or horizontally, making the molten copper susceptible to sudden changes in gravity, resulting in flow fluctuations and causing casting interruptions or overflows. Summary of the Invention

[0004] The purpose of the present invention is to overcome the problem that the existing copper rod casting equipment has a single inclination angle to adjust the copper liquid flow rate, which leads to casting interruption or overflow, and provide a casting equipment for copper rod production.

[0106] like Figures 1 to 24 As shown, a casting device for copper rod production includes a frame 1, a crystallization mechanism 4, the crystallization mechanism 4 is arranged on the front surface of the frame 1, and a crystallization wheel 41 is rotatably arranged in the middle of the front side of the crystallization mechanism 4; a ladle dumping mechanism 2, the ladle dumping mechanism 2 is fixedly mounted on the upper middle part of the frame 1, the ladle dumping mechanism 2 includes a ladle mounting seat 22 and a ladle 25 mounted on the ladle mounting seat 22, and a ceramic tube 2501 is obliquely arranged on the front side wall of the ladle 25; a stopper rod control mechanism 5 is also provided on the front side wall of the ladle 25 for controlling the outlet volume of the ceramic tube 2501; an ingot lifting mechanism 3 is arranged on the front side of the frame 1, located on one side of the crystallization mechanism 4, for removing the crystallized copper ingot from the crystallization wheel groove 4101 and conveying it to the next process;

[0107] like Figures 2 to 8 As shown, the ladle tipping mechanism 2 includes a base 20, which is configured as a plate structure and is fixed to the upper portion of the frame 1 by bolts. A movable base 21 is rotatably provided on the upper surface of the base 20 via a hinge seat 2001.

[0108] In order to control the rotation of the movable base 21 and realize the control of the ladle in the left and right directions, a first slot 2101 is opened on the left surface of the movable base 21, and a fixed frame 2104 is fixedly provided on the upper surface of the movable base 21. The fixed frame 2104 is located above the first slot 2101; a vertical screw lifting member 2901 is provided on the left side of the surface of the base 20 through a first fixed mounting seat 2904, and the movable end of the vertical screw lifting member 2901 passes through the first slot 210 1 and is connected to the bottom of the fixed frame 2104 through the first hinged support 2907, which is used to drive the movable base 21 to tilt left and right. When the vertical screw lifter 2901 is extended, the movable end of the vertical screw lifter 2901 is connected to the first hinged support 2907, and the first hinged support 2907 is connected to the bottom of the fixed frame 2104. At this time, the vertical screw lifter 2901 is equivalent to pushing the movable base 21 to tilt to the other side, wherein the hinged seat 2001 serves as the fulcrum for rotation.

[0109] In order to realize the displacement control of the ladle mounting seat 22 in the front-to-back direction, a second slot 2102 is provided on the rear surface of the movable base 21; a horizontal screw lifting member 2902 is provided on the rear side of the lower surface of the movable base 21 through the second movable mounting seat 2905, and the movable end of the horizontal screw lifting member 2902 is located below the second slot 2102 and is connected to the bottom of the ladle mounting portion 2202 through the second hinged support 2908, which is used to drive the ladle mounting seat 22 to move in the front-to-back direction; when the horizontal screw lifting member 2902 is working, it can push the ladle mounting seat 22 to move in the front-to-back direction; in this solution, the length of the second slot 2102 is greater than the stroke length of the horizontal screw lifting member 2902.

[0110] In order to achieve the control of the displacement stroke, a support ear 2206 is provided at the bottom of the ladle mounting part 2202; a limiting assembly 28 is also provided on both sides of the upper surface of the movable base 21 along the movement direction of the horizontal screw lifting member 2902; the limiting assembly 28 includes a transverse displacement seat 2801; specifically, the transverse displacement seat 2801 is configured as an inverted T-shape; a stroke groove 2802 is provided in the middle of the vertical plate surface; a limiting column 2803 passes through the support ear 2206 and is arranged in the stroke groove 2802, and can slide in the stroke groove 2802, and nuts are screwed on both ends of the limiting column 2803.

[0111] On the other hand, in order to ensure the stability of the ladle mounting seat 22 during movement, guide assemblies 27 are also provided on both sides of the upper surface of the movable base 21 along the horizontal driving direction of the screw lifting member 2902; the guide assembly 27 includes a roller support 2701 fixedly provided on the upper surface of the movable base 21, and a roller 2702 is provided on the roller support 2701; a slide rail 2703 fixedly provided at the bottom of the ladle mounting portion 2202, and the slide rail 2703 is slidably engaged and sleeved on the roller 2702.

[0112] In this solution, the two support ears 2206 and the second hinged support 2908 form a three-point connection, so that the movable base 21 is connected to the ladle mounting seat 22. When the movable base 21 works, the ladle mounting seat 22 and the movable base 21 work synchronously.

[0118] The ladle mounting portion 2202 is configured as a box structure, wherein a ladle mounting groove 2203 is provided in the middle of the ladle mounting portion 2202, and the ladle 25 is mounted in the ladle mounting groove 2203;

[0119] Sensor mounting positions 2204 are symmetrically arranged on both sides of the ladle mounting groove 2203; a pressure sensor assembly 24 is embedded in each of the sensor mounting positions 2204. In this embodiment, there are four sensor mounting positions 2204 and four pressure sensor assemblies 24. Specifically, the pressure sensor assembly 24 includes a tray 2401 embedded in the sensor mounting position 2204, a pressure sensor 2402 mounted within the tray 2401, and electrically connected to an external control device; a protective cover 2403 disposed within the tray 2401 and positioned above the pressure sensor 2402; and support bolts 2404 slidably disposed within the tray 2401 and positioned above the protective cover 2403. Outwardly extending wings 2205 are provided on both sides of the ladle 25, each of which has through-holes corresponding to the support bolts 2404. The top ends of the support bolts 2404 are inserted into the through-holes to secure the ladle 25.

[0120] The ladle 25 is mounted on the ladle mounting seat 22. A ladle cover 26 is fixedly provided above the ladle 25, and a gas device is provided on the top of the ladle cover 26. The bottom of the ladle 25 is set in a V shape, and a ceramic tube 2501 is obliquely provided on the front side wall of the ladle 25. The ceramic tube 2501 passes through the V-shaped surface and is used to pour the molten copper into the crystallization mechanism.

[0121] The working process of this device:

[0122] like Figure 1 As shown, the ladle mechanism 2 is mounted on the frame 1. First, molten copper is poured into the ladle 25, with the ceramic tube 2501 aligned with the crystallization tank of the crystallization mechanism. Four pressure sensor assemblies 24 monitor the pressure value in real time and transmit it to an external control device. The external control device uses the pressure value at that position to control the tilting or movement of the ladle 25. During operation, the control equipment coordinates the three groups of screw lifting parts to move together according to the casting process parameters: left and right tilt angle adjustment: when the vertical screw lifting part 2901 is extended, the fixed frame 2104 is pushed to make the movable base 21 tilt to the right around the hinge axis, and tilt to the left when shortened, so as to realize the left and right angle adjustment of the ladle 25; front and back position adjustment: when the horizontal screw lifting part 2902 is driven, the push rod moves horizontally along the length direction of the second slot 2102, driving the ladle mounting seat 22 to slide back and forth along the guide assembly 27, and adjust the horizontal docking position of the ceramic tube 2501 and the crystallizer; front and back tilt angle adjustment: when the oblique screw lifting part 2903 is driven, the ladle mounting seat 22 is made to pitch around the axis of the support ear 2206 to accurately control the flow rate of the molten copper.

[0123] The pressure sensor assembly 24 monitors the load differential between the two side wings 2205 in real time. When the detected weight deviation exceeds a set threshold, the control device automatically adjusts the stroke of each lifting component to compensate for the shift in the center of gravity of the ladle 25. During the pouring process, the limit pin 2803 slides within the travel groove 2802, ensuring freedom of movement while preventing mechanical overload.

[0124] like Figures 21-24 As shown, the stopper rod control mechanism 5 includes a mounting base 51, which is fixedly mounted on the front side wall of the ladle 25; specifically, the mounting base 51 is made of high-temperature resistant stainless steel and is fixed to the front side wall of the ladle 25 by a bolt group at an angle consistent with the angle of the ceramic tube 2501.

[0125] This mechanism, through the three-drive linkage design of the vertical screw lift, the horizontal screw lift, and the oblique screw lift, can precisely and independently control the three dimensions of the ladle: left and right tilt, front and back translation, and front and back pitch. This can stabilize the flow rate of the molten copper in the ladle and improve the casting accuracy. By coordinating the limit assembly with the guide assembly and adopting a structure in which the stroke groove is combined with the limit column, while allowing the ladle mounting seat to move through the specified stroke, it effectively prevents the ladle from shifting under high-temperature conditions, thereby improving the safety of the ladle during use. By incorporating a multi-layer protection design of the pressure sensor assembly and using a combined structure of a tray, a protective cover, and support bolts, the pressure detection accuracy is guaranteed, and the influence of thermal radiation from the high-temperature copper liquid is effectively isolated, thereby increasing the service life of the sensor.

[0126] The mounting base 51 is provided with a limited position fixing block 5101; a support slide 55 is slidably provided on the limited position fixing block 5101 along the length of the mounting base 51, and a fixing clamp 5501 is provided at the top of the support slide 55; a limited position stopper 5502 is provided at the end of the support slide 55. Specifically, the limited position fixing block 5101 is welded to the surface of the mounting base 51, and a T-shaped groove is provided inside the limited position fixing block 5101, which cooperates with the dovetail guide rail of the support slide 55, allowing the support slide 55 to slide along the length of the mounting base 51. The fixing clamp 5501 is fixedly connected to the middle portion of the movable connecting arm 54. Specifically, the fixing clamp 5501 is configured as a U-shape, and the movable connecting arm 54 is embedded in the U-shaped groove.

[0127] The stopper screw lifter 53 is detachably mounted on the mounting base 51 via a connector assembly 52. ​​Specifically, the connector assembly 52 comprises a triangular body 5201 fixed to the surface of the mounting base 51. The front end of the triangular body 5201 is integrally formed with two symmetrically arranged protruding plates 5202, the inner surfaces of which are machined with anti-slip serrations. The bottom end of the stopper screw lifter 53 is located between the two protruding plates 5202 and secured by a fastening bolt 5203. The base of the stopper screw lifter 53 is inserted between the two protruding plates and secured by a preload applied by a high-strength fastening bolt 5203.

[0128] In this solution, the stopper rod screw lifting member 53 is in the prior art and includes at least a drive motor and a screw lifting member; the drive motor is electrically connected to an external control device and is controlled by an external program to achieve regulation of the copper liquid flow.

[0129] One end of the movable connecting arm 54 is hinged to the movable end of the stopper rod screw lifting member 53 through the first auxiliary support 5401; specifically, when the stopper rod screw lifting member 53 is extended, under the guide limit of the support slide 55, the movable connecting arm 54 moves in the vertical direction along the support slide 55.

[0130] The main clamp 56 is fixedly provided at one end of the movable connecting arm 54. A stopper rod 57 is detachably provided on the main clamp 56. The head end of the stopper rod 57 is inserted into the ladle 25 and is located in the ceramic tube 2501 for controlling the casting amount of the molten copper. Specifically, the main clamping member 56 includes a first clamping block 5600 fixedly mounted at one end of the movable connecting arm 54; a fastening block 5607 fixedly mounted on the side wall of the movable connecting arm 54 and having a fastening notch; an L-shaped connecting block 5601 hingedly mounted on the end of the first clamping block 5600; a second clamping block 5602 fixedly mounted on the inner side of the L-shaped connecting block 5601; a locking screw 5605 hingedly mounted on one side of the second clamping block 5602 via a second auxiliary member 5603; the other end of the locking screw 5605 rotates into the fastening notch and is secured by a locking nut 5608. Specifically, the first clamping block 5600 is welded to the end of the movable connecting arm 54, and a fastening block 5607 with a fastening notch is welded to the side wall of the first clamping block 5601. L-shaped connecting block 5601 is hinged to first clamping block 5600 via a pin. Second clamping block 5602, welded to its inner side, is covered with a high-temperature-resistant ceramic gasket. Locking screw 5605 passes through the axial hole of second auxiliary component 5603 and its end is screwed into locking nut 5608, forming an adjustable clamping cavity for plug rod 57.

[0131] How this mechanism works: Step 1: Initial Installation: a. Align the mounting base 51 with the pre-set mounting holes on the front wall of the ladle 25 and tighten with bolts, ensuring the base flatness error is ≤0.1mm / m. b. Insert the support slide 55 into the slot of the limit fixing block 5101 and manually push the slide to test the sliding resistance. c. Insert the base of the stopper rod screw lift 53 between the protruding plates 5202 of the connector assembly 52 and tighten the tightening bolts 5203. Step 2: Stopper Rod Assembly: a. Loosen the locking nut 5608 of the main clamp 56 and tilt the L-shaped connecting block 5601 outward to its maximum opening angle. b. Place the stopper rod 57 into the opening angle of the main clamp 56, aligning the front end of the stopper rod 57 with the ceramic tube 2501. c. Close the L-shaped connecting block 5601, aligning the ceramic gasket of the second clamp 5602 with the stopper rod surface, and tighten the locking screw 5605 until the stopper rod stops moving axially. Step 3: Casting Control: The drive motor is activated, and the stopper screw lifter 53 pushes the movable connecting arm 54 upward. The supporting slide 55 slides synchronously along the chute, lifting the stopper 57 away from the mouth of the ceramic tube 2501, and the molten copper begins to flow into the crystallization wheel. The stopper target height is set by an external control device. The electric cylinder provides real-time feedback on the position signal, dynamically adjusting the stopper opening to maintain a stable copper flow rate within the set range. When changes in the crystallization wheel speed are detected, the control system automatically calculates the stopper displacement compensation and corrects the opening to prevent overflow or flow interruption.

[0132] This mechanism uses a mechanical transmission mechanism to achieve a linear correspondence between the stopper rod lifting displacement and the ceramic tube opening, which can effectively improve the copper liquid flow regulation accuracy, eliminate the ingot size fluctuations caused by differences in manual experience, and improve the product qualification rate; at the same time, through the detachable setting of the connecting components and the main clamp, the mechanism can be quickly disassembled and replaced, further improving the product casting efficiency.

[0133] like Figures 9 to 13 As shown, the ingot starting mechanism 3 includes a first adjusting member 31 , which is fixed on the frame 1 through an L-shaped fixing plate 311 and is located on one side of the crystallization wheel 41 ; specifically, the first adjusting member 31 is located at the end of the copper block of the crystallization wheel 41 .

[0134] The first adjusting member 31 includes a main cylinder 316, which is fixedly mounted on an L-shaped fixing plate 311. A sliding cylinder 317 is slidingly arranged inside the main cylinder 316. One end of the sliding cylinder 317 is fixedly connected to the rotating sleeve 331, and the other end is provided with a threaded sleeve 3172. A threaded hole is provided in the middle of the threaded sleeve 3172.

[0135] A base plate 312 is further extended from one side of the vertical plate of the L-shaped fixing plate 311, and a support bearing seat 313 is provided on the base plate 312. A driving rod 314 passes through both the L-shaped fixing plate 311 and the support bearing seat 313. The driving rod 314 includes a smooth section 3141 and a threaded section 3142. The threaded section 3142 is screwed together with the threaded sleeve 3172 to control the sliding cylinder 317 to slide along the interior of the main cylinder 316. Specifically, when the driving rod 314 rotates, the entire body only rotates and does not produce radial displacement. Since the threaded section 3142 is screwed together with the threaded sleeve 3172, when the threaded section 3142 rotates, it pushes the sliding cylinder 317 to move along the channel of the main cylinder 316, thereby controlling the axial movement of the spindle assembly 33 along the main cylinder 316.

[0136] To further control the travel of the sliding cylinder 317, the central surface of the sliding cylinder 317 is recessed to form a sliding limit groove 3171. The length of the main cylinder 316 is shorter than the sliding limit groove 3171. To facilitate control of the drive rod 314, a rotating handle 315 is provided at the head end of the drive rod 314. A protective shield 34 is also provided on the exterior of the first adjustment member 31. The sliding limit groove 3171 on the surface of the sliding cylinder 317 limits the adjustment travel while avoiding structural interference. Combined with the protective shield 34's full protection of the first adjustment member 31, it effectively blocks high-temperature metal splashing and reduces equipment failure rate.

[0137] In this solution, the spindle assembly 33 is fixedly arranged at the front end of the first adjusting member 31; the spindle assembly 33 includes a rotating sleeve 331, and the rotating sleeve 331 is fixedly arranged at the front end of the first adjusting member 31; a hollow straight tube 332 is fixedly inserted into the rotating sleeve 331, and the end of the hollow straight tube 332 is connected to the external cooling water source, and the front end of the hollow straight tube 332 is closed; a connecting arm 333, one end of which is fixedly sleeved on the hollow straight tube 332, and the other end is fixedly sleeved on the hollow straight tube 332. A support rod 334 is provided at one end; the main rotating roller 335 is rotatably mounted on the support rod 334 through a bearing; the ingot removing knife 336 is fixedly mounted on the front end of the hollow straight tube 332, and is located on the lower side of the main rotating roller 335; the surface of the ingot removing knife 336 is provided with a spray hole 337, and the spray hole 337 is connected to the hollow straight tube 332; the ingot removing end of the ingot removing knife 336 is fitted into the crystallization wheel groove 4101 of the crystallization wheel 41 to realize demolding of the copper ingot.

[0138] To facilitate the guidance of the demolded copper ingots for the next process, a bridge assembly 32 is also included. The bridge assembly 32 is composed of multiple unit bridge members 321. Specifically, the unit bridge members 321 include a bridge groove 3211, the bottom of which is provided with a hollow notch 3212; a guide rotating cylinder 3213 rotatably arranged in the bridge groove 3211, located at the hollow notch 3212; and a collection groove 3214 fixedly arranged below the hollow notch 3212. A collection box 3215 can be pulled out and arranged in the collection groove 3214. Specifically, the guide rotating cylinder 3213 includes a shaft, two bearings sleeved on the shaft, and a cylinder sleeved on the two bearings. The guide rotating cylinder 3213 of the bridge assembly cooperates with the collection box 3215 to simultaneously collect oxidized debris while conveying the copper ingots.

[0139] To adjust the approach bridge assembly so that it can cooperate with the spindle assembly, a bridge adjustment member is provided within the frame 1. The bridge adjustment member includes a bridge rotation shaft 323, which is rotatably mounted within the frame 1 via a bridge bearing seat 325. One end of the bridge rotation shaft 323 extends through the frame 1 and is fixedly connected to the bridge rotation shaft 323 via a sleeve 326. A bridge adjustment hydraulic cylinder 322 is fixedly mounted within the frame 1. The movable end of the bridge adjustment hydraulic cylinder 322 is hingedly provided with a bridge support arm 324, the other end of which is fixedly sleeved onto the approach bridge rotation shaft 323. The linkage design in which the bridge adjustment hydraulic cylinder 322 drives the bridge support arm 324 enables dynamic adjustment of the conveying angle to meet the requirements of different production cycles.

[0140] The working process of this device is as follows: 1. Ingot preparation stage: drive the crystallization wheel 41 to rotate to the preset position, start the cooling water source, and inject water into the ingot block 336 through the hollow straight pipe 332; operate the rotating handle 315 to fine-tune the position of the ingot block 336 to ensure that the spray hole 337 is facing the bottom of the copper ingot in the crystallization wheel groove 4101. 2. Demolding execution stage: When the crystallization wheel 41 rotates and drives the crystallized copper ingot to move to the ingot lifting station, the ingot lifting knife scrapes the copper ingot from the crystallization wheel groove 4101. At the same time, cooling water is sprayed out from the spray hole 337 through the hollow straight pipe 332 to form a water film lubrication interface, so that the copper ingot is separated from the crystallization wheel groove 4101; the scraped copper ingot contacts the surface of the main rotating roller 335 to reduce sliding friction; the demolded copper ingot is transported along the guide rotating cylinder 3213 of the unit approach bridge 32, and the oxidized debris falls into the collection box 3215 through the hollow notch 3212. 3. Dynamic adjustment and maintenance stage: During the production process, the stroke of the drive rod 314 is adjusted according to the specifications of the copper ingot, and the wear of the ingot lifting block 336 is compensated in real time; the collection box 3215 is regularly pulled out to clean the debris. After the protective cover 34 is disassembled, the worn ingot lifting assembly 33 can be directly replaced without stopping the machine and disassembling the entire machine. 4. Shutdown protection stage: After turning off the cooling water source, reversely rotate the drive rod 314 to disengage the ingot block 336 from the crystallization wheel groove 4101 to avoid cold deformation of the equipment; operate the approach bridge adjustment hydraulic cylinder 322 to reset the approach bridge assembly to a horizontal position to prevent the mechanism from being subjected to long-term stress.

[0141] This mechanism integrates the spray holes into the ingot lifting knife and connects the hollow straight pipe with the external cooling water source to achieve directional spray cooling during the demoulding process of the copper ingot, effectively inhibiting the formation of the oxide layer and improving the surface quality of the copper ingot. At the same time, the first adjustment member adopts a nested design of the sliding cylinder and the main cylinder, and cooperates with the threaded transmission structure of the drive rod, so that the ingot lifting knife can be adjusted independently along the axial direction. In case of local wear, it is only necessary to adjust the position of the ingot lifting knife to replace the ingot lifting assembly separately, which reduces maintenance time. The main rotating roller is connected to the support rod through a bearing and forms a rolling contact with the copper ingot during the ingot lifting process. Combined with the cooling and lubricating effect of the spray holes, the wear rate of the crystallization wheel groove is reduced, extending the service life of the equipment. The guide rotating cylinder of the approach bridge assembly cooperates with the collection box to simultaneously collect oxidized debris when conveying the copper ingot. The linkage design of the approach bridge adjustment hydraulic cylinder driving the approach bridge support arm realizes dynamic adjustment of the conveying angle to meet the needs of different production rhythms.

[0142] like Figures 14 to 20 As shown, the crystallization mechanism 4 includes a first driving member 410, the output end of which passes through the frame 1 and is sleeved with a crystallization wheel 41; specifically, the first driving member 410 is configured as a reduction motor with a main shaft, which passes through the frame 1 and is connected to the crystallization wheel 41 through supporting components such as a bearing sleeve, a bearing, and a spacer sleeve, thereby controlling the crystallization wheel 41 to rotate slowly and uniformly;

[0143] The outer edge of the wheel body of the crystallization wheel 41 is recessed to form a crystallization wheel groove 4101; specifically, the crystallization wheel 41 includes an inner crystallization wheel splint located on the inner side, and a crystallization wheel body is fixedly provided on the outer side surface of the inner crystallization wheel splint. The crystallization wheel body is configured to be circular and has a groove in its cross section, which is the crystallization wheel groove 4101.

[0144] The cooling pipe group 47 is fixedly installed on the front side of the frame 1 and is located around the crystallization wheel 41; in this solution, the cooling pipe group 47 includes a first main cooling spray pipe 4701, which is located on the inner side of the crystallization wheel groove 4101, and the spraying direction is directed to the inner groove wall of the crystallization wheel groove 4101; a second main cooling spray pipe 4704, which is located on the outer side of the crystallization wheel groove 4101; a first auxiliary cooling spray pipe 4702, which is located on the rear outer side of the crystallization wheel groove 4101; and a second auxiliary cooling spray pipe 4703, which is located on the front outer side of the crystallization wheel groove 4101. The spraying directions of the second main cooling spray pipe 4704, the first auxiliary cooling spray pipe 4702 and the second auxiliary cooling spray pipe 4703 are toward the steel belt 411; and a third main cooling spray pipe 4705, which is located on the front side of the crystallization wheel groove 4101, and the spraying direction is directed to the groove wall of the crystallization wheel groove 4101. Specifically, the cooling spray pipe includes a pipe body and nozzles evenly arranged on the pipe body. A straight pipe connected to the outside is provided on the pipe body, and the straight pipe is connected to the external liquid supply pipe. Specifically, the first main cooling spray pipe 4701 is located on the inner side of the crystallization wheel groove 4101, and the spray angle is perpendicular to the inner wall of the groove; the second main cooling spray pipe 4704 is located on the outer side of the groove, and the spray direction forms a 45° angle with the steel strip 411; the first auxiliary cooling spray pipe 4702 and the second auxiliary cooling spray pipe 4703 cover the surface of the steel strip 411 obliquely from the back and front sides respectively; the third main cooling spray pipe 4705 is arranged on the front side of the crystallization wheel groove 4101, and the spray flow channel is consistent with the tangent direction of the groove wall. Through the multi-directionally arranged cooling pipe group 47, all-round uniform cooling of the crystallization wheel groove 4101 and the inside and outside of the steel strip is achieved, effectively suppressing stress concentration inside the copper rod and improving grain refinement. Preferably, the third main cooling spray pipe 4705 sprays the front wall of the crystallization wheel groove in a directional manner, which can accurately adjust the temperature gradient at the crystallization front and avoid surface defects caused by local overcooling.

[0145] A steel pulley assembly is arranged around the crystallization wheel 41 and includes a first steel pulley 46, rotatably mounted on the frame 1 and located on the left side of the crystallization wheel 41; a second steel pulley 45, rotatably mounted on the frame 1 and located on the lower left side of the crystallization wheel 41; a third steel pulley 44, rotatably mounted on the frame 1 and located on the lower right side of the crystallization wheel 41; a fourth steel pulley 42, rotatably mounted on the frame 1 and located on the upper right corner of the crystallization wheel 41; and a fifth steel pulley 43, rotatably mounted on the frame 1 and located on the upper right side of the fourth steel pulley 42. The crystallization channel 400 is configured as an arc-shaped structure, with the arc starting at the contact point between the fourth steel pulley 42 and the crystallization wheel 41 and ending at the contact point between the first steel pulley 46 and the crystallization wheel 41. The arc path formed by the five sets of steel pulleys prolongs the solidification time of the molten copper. Combined with the gradual curvature design from the fourth steel pulley 42 to the first steel pulley 46, the molten copper shrinks in a controlled manner during solidification, reducing porosity defects.

[0146] The steel belt 411 is sleeved on the steel belt pulley assembly and is used to form a crystallization channel 400 with the crystallization wheel groove 4101 on the outer wall of the crystallization wheel 41.

[0147] In order to achieve the degree of tightening of the steel belt 411, so that the steel belt 411 is airtight when in contact with the crystallization wheel groove 4101, and to prevent leakage of copper liquid, the interior of the frame 1 is also provided with a first swing mechanism 49, which includes a swing fixed plate fixedly arranged on the side of the frame 1, and a swing through groove is provided on the swing fixed plate; the swing through groove is a rectangular groove; a first rotating arm, one end of the first rotating arm is hinged to one end of the swing fixed plate; the other end of the first rotating arm is provided with a hollow rotating sleeve, and the rotating shaft of the second steel belt pulley is rotatably inserted into the hollow rotating sleeve; a first hydraulic cylinder, the first hydraulic cylinder is built into the frame 1, and the movable end of the first hydraulic cylinder passes through the frame 1 and the swing through groove, and is connected to the first rotating arm through a hinge seat. Specifically, the swing fixed plate is welded to the side of the frame 1. One end of the first rotating arm is hinged to the swing fixed plate, and the other end is mounted with the second steel belt pulley 45 through a hollow rotating sleeve. The piston rod of the first hydraulic cylinder passes through the swing slot and is hinged to the upper middle part of the first rotating arm. The piston rod is extended and retracted to drive the second steel pulley 45 to rotate along the hinge, thereby increasing the tension on the lower side of the steel belt 411.

[0148] In order to ensure the sealing of the crystallization channel 400 during the casting of the molten copper, a second swinging mechanism 48 is also provided inside the frame 1, and the second swinging mechanism 48 includes a central connecting shaft 4803, and the central connecting shaft 4803 is arranged to pass through the frame 1 as a whole. The front end of the central connecting shaft 4803 passes through the frame 1 and is fixedly sleeved with a connecting arm 4805, and the rear end of the central connecting shaft 4803 is movably fixed in the frame 1 through a rotating seat; the rotating shaft of the fourth steel pulley 42 is inserted into the other end of the connecting arm 4805; a second hydraulic cylinder 4801, the second hydraulic cylinder 4801 is built into the frame 1, and the movable end of the second hydraulic cylinder 4801 is connected to a pushing arm 4804 through a U-shaped hinge seat 4802; the pushing arm 4804 is fixedly sleeved on the central connecting shaft 4803. The central connecting shaft 4803 passes through the frame 1 through a bearing, and its front end is fixedly connected to the two support arms, and the fourth steel pulley 42 is rotatably installed between the two support arms; the piston rod of the second hydraulic cylinder 4801 rotates the central connecting shaft 4803 through the push arm 4804 to control the gap between the fourth steel pulley 42 and the crystallization wheel 41 to adapt to different copper liquid flow rates.

[0149] Preferably, in order to prevent the copper slag on the surface of the steel strip from affecting the subsequent copper liquid casting, the frame 1 is further provided with a U-shaped backflush pipe 413, which is intermittently clamped on both sides of the steel strip 411 and is located between the third steel pulley 44 and the fifth steel pulley 43. Specifically, the U-shaped backflush pipe 413 is made of 316L stainless steel, and the pipe body is provided with two exhaust holes, through which high-pressure air is ejected to remove the copper slag remaining on both sides of the steel strip 411.

[0150] In order to further increase the ability of the steel belt 411 to fit the crystallization wheel 41 during operation, a steel pulley shield 412 is further provided on the frame 1 . The steel pulley shield 412 is located at the upper right corner of the fourth steel pulley 42 .

[0151] The working method of this device is as follows: the first driving member 410 is started to drive the crystallization wheel 41 to rotate. At this time, the fourth steel pulley 42 rotates synchronously under the action of the steel belt, and the steel belt 411 circulates along the path of the fourth steel pulley 42 → crystallization wheel 41 → first steel pulley 46 → second steel pulley 45 → third steel pulley 44 → fifth steel pulley 43; the angle of the fourth steel pulley 42 is adjusted by the second hydraulic cylinder 4801 to match the inlet curvature of the crystallization channel 400 with the flow rate of the copper liquid; the molten copper liquid is injected into the crystallization channel 400 from the pouring port, and the cooling pipe group 47 starts spraying. The copper liquid is initially solidified in the crystallization wheel groove 4101 to form a copper rod blank; the steel belt 411 is reversely blown at the U-shaped backflush pipe 413 to remove surface oxides; the formed copper rod is pulled out by the traction machine and enters the subsequent rolling process.

[0152] This mechanism achieves efficient and stable control of the copper liquid and copper rod crystallization process by integrating the cooling tube group with the multi-wheel steel belt system and the crystallization wheel. By fixing the cooling tube group around the crystallization wheel and covering the crystallization wheel groove and the steel belt surface with multi-angle spraying, the inner and outer layers of the copper rod are cooled synchronously and evenly through directional cooling, which improves the grain refinement, effectively eliminates internal shrinkage holes and surface crack defects, and improves the product qualification rate. By surrounding the circumference of the crystallization wheel with a steel belt pulley group to form a closed-loop support structure, the steel belt is tightened by the multi-wheel group and fits tightly with the crystallization wheel groove, forming a continuous and stable arc-shaped crystallization channel. Compared with the single-belt single-point contact design, the multi-wheel group layout expands the steel belt wrapping range to more than 180° from the outer edge of the crystallization wheel, reducing the probability of copper liquid leakage and ensuring a regular cross-sectional shape without the risk of broken rods.

[0153] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
