Description

[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 for continuous casting of copper rods. Steel belt wheel continuous casting machines usually include steel belt, steel belt wheel and 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, and the formed cast billet is pulled out from the billet outlet.

During operation, the control device coordinates the three groups of screw lifting parts to work together according to the casting process parameters: left and right inclination 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 achieve left and right angle adjustment of the ladle 25; front and rear 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 adjusting the horizontal docking position of the ceramic tube 2501 and the crystallizer; front and rear inclination 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 copper liquid.

[0035] The pressure sensor assembly 24 monitors the load difference of the two side wing plates 2205 in real time. When the weight deviation is detected to exceed the set threshold, the control device automatically adjusts the stroke of each lifting component to compensate for the center of gravity deviation of the ladle 25. During the pouring process, the limit column 2803 slides in the stroke groove 2802, which not only ensures the freedom of movement but also prevents mechanical overload.

[0036] like Figures 21 to 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.

[0037] This mechanism can control the three-dimensional precise independent control of the left and right tilt, front and rear translation, and front and rear pitch of the ladle through the three-drive linkage design of the vertical screw lift, the horizontal screw lift, and the oblique screw lift, which 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 the structure of the stroke groove and the limit column, while allowing the ladle mounting seat to move the specified stroke, it effectively prevents the ladle from shifting under high temperature conditions, thereby improving the safety of the ladle when in use. Through the multi-layer protection design of the pressure sensor assembly, through the combined structure of the tray, cover and support bolts, it not only ensures the pressure detection accuracy, but also effectively isolates the influence of the thermal radiation of the high-temperature copper liquid, thereby increasing the service life of the sensor.

[0038] The mounting base 51 is provided with a limited position fixing block 5101; the limited position fixing block 5101 is slidably provided with a support slide bar 55 along the length direction of the mounting base 51, and a fixed clamp 5501 is provided at the top of the support slide bar 55; the end of the support slide bar 55 is provided with a limited position blocking member 5502; specifically, the limited position fixing block 5101 is welded on the surface of the mounting base 51, and a T-shaped slide groove is provided inside the limited position fixing block 5101, which cooperates with the dovetail guide rail of the support slide bar 55 to allow the support slide bar 55 to slide along the length direction of the mounting base 51. The fixed clamp 5501 is fixedly connected to the middle part of the movable connecting arm 54, and specifically, the fixed clamp 5501 is set to be U-shaped, and the movable connecting arm 54 is embedded in the U-shaped groove.

[0039] The stopper screw lifting member 53 is detachably arranged on the mounting base 51 through the connecting member group 52; specifically, the connecting member group 52 includes a triangular body 5201 fixed on the surface of the mounting base 51, and the front end of the triangular body 5201 is integrally provided with two symmetrically arranged protruding plates 5202, and the inner sides of the two plates are processed with anti-slip teeth; the bottom end of the stopper screw lifting member 53 is located between the two protruding plates 5202 and is fixed by a fastening bolt 5203. The base of the stopper screw lifting member 53 is inserted between the two protruding plates and fixed by applying a pre-tightening force through the high-strength fastening bolt 5203.

[0040] In this solution, the stopper rod screw lifting member 53 is in the prior art and includes at least one drive motor and one 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 rate.

[0041] 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 bar 55, the movable connecting arm 54 moves in the vertical direction along the support slide bar 55.

[0042] The main clamp 56 is fixedly arranged at one end of the movable connecting arm 54. A stopper rod 57 is detachably arranged 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 copper liquid. Specifically, the main clamp 56 includes a first clamp 5600, which is fixedly arranged at one end of the mobile connecting arm 54; a fastening block 5607, which is fixedly arranged on the side wall of the mobile connecting arm 54 and has a fastening notch; an L-shaped connecting block 5601, which is hingedly arranged at the end of the first clamp 5600; a second clamp 5602 is fixedly arranged on the inner side of the L-shaped connecting block 5601; a locking screw 5605 is hingedly arranged on one side of the second clamp 5602 through a second auxiliary member 5603, and the other end of the locking screw 5605 is rotated to the fastening notch and fixed by a locking nut 5608. Specifically, it includes a first clamp 5600 welded to the end of the mobile connecting arm 54, and a fastening block 5607 with a fastening notch is welded on its side wall. The L-shaped connecting block 5601 is hinged to the first clamping block 5600 through a pin, and the surface of the second clamping block 5602 welded inside is covered with a high-temperature resistant ceramic gasket. After the locking screw 5605 passes through the axial hole of the second auxiliary part 5603, the end is screwed into the locking nut 5608 to form an adjustable clamping cavity, which is suitable for the plug rod 57.

[0043] Working method of this mechanism: Step 1: Initial installation: a. Align the mounting base 51 with the preset mounting hole on the front wall of the ladle 25, and tighten it with bolts to ensure that the flatness error of the base is ≤0.1mm / m. b. Insert the support slide bar 55 into the slide groove of the limit fixing block 5101, and manually push the slide bar to test the sliding resistance. c. Insert the base of the stopper rod screw lifting member 53 between the protruding plates 5202 of the connecting member group 52, and tighten the tightening bolts 5203. Step 2: Stopper rod assembly: a. Loosen the locking nut 5608 of the main clamp 56, and turn the L-shaped connecting block 5601 outward to the maximum opening and closing angle. b. Put the stopper rod 57 into the opening and closing angle of the main clamp 56, so that the front end of the stopper rod 57 is aligned with the ceramic tube 2501. c. Close the L-shaped connecting block 5601, so that the ceramic gasket of the second clamp 5602 fits the surface of the stopper rod, and tighten the locking screw 5605 until the stopper rod has no axial movement. Step 3: Casting control: Start the drive motor, the stopper rod screw lifting member 53 pushes the mobile connecting arm 54 up, and the support slide bar 55 slides synchronously along the slide slot, so that the stopper rod 57 is lifted off the mouth of the ceramic tube 2501, and the copper liquid begins to flow into the crystallization wheel. The stopper rod target height is set through the external control device, and the electric cylinder feeds back the position signal in real time, dynamically adjusts the stopper rod opening, and stabilizes the copper liquid flow rate within the set value range. When the crystallization wheel speed changes, the control system automatically calculates the stopper rod compensation displacement, completes the opening correction, and avoids overflow or interruption.

[0044] This mechanism realizes the linear correspondence between the lifting displacement of the stopper rod and the opening of the ceramic tube by adopting a mechanical transmission mechanism, which can effectively improve the copper liquid flow regulation accuracy, eliminate the fluctuation of the ingot size 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 clamps, the mechanism can be quickly disassembled and replaced, further improving the product casting efficiency.

[0045] like Figures 9 to 13 As shown, the ingot lifting 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 .

[0046] 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 slidably 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 arranged in the middle of the threaded sleeve 3172.

[0047] A bottom plate 312 is also extended from one side of the vertical plate of the L-shaped fixing plate 311, and a support bearing seat 313 is arranged on the bottom plate 312; a driving rod 314 passes through the L-shaped fixing plate 311 and the support bearing seat 313 at the same time, and the driving rod 314 includes a smooth section 3141 and a threaded section 3142, and the threaded section 3142 is spirally connected with the threaded sleeve 3172 to control the sliding cylinder 317 to slide along the inside of the main cylinder 316. Specifically, when the driving rod 314 rotates, the whole only rotates, and no radial displacement occurs. Since the threaded section 3142 is threadedly connected with the threaded sleeve 3172, when the threaded section 3142 rotates, it will push the sliding cylinder 317 to move along the channel of the main cylinder 316, thereby controlling the spindle assembly 33 to move axially along the main cylinder 316.

[0048] In order to further control the movement stroke of the sliding cylinder 317, the middle surface of the sliding cylinder 317 is recessed to form a sliding limit groove 3171, and the length of the main cylinder 316 is less than the length of the sliding limit groove 3171. In order to facilitate the control of the driving rod 314, a rotating handle 315 is provided at the head end of the driving rod 314. A shield 34 is also provided on the outside of the first adjustment member 31. The sliding limit groove 3171 is provided on the surface of the sliding cylinder 317 to limit the adjustment stroke while avoiding structural interference. Combined with the full wrapping protection of the first adjustment member 31 by the shield 34, it effectively blocks the splashing of high-temperature metal and reduces the failure rate of the equipment.

[0049] 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 an 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 of which is fixedly sleeved on the hollow straight tube 332. A support rod 334 is sleeved at one end; a main rotating roller 335 is rotatably mounted on the support rod 334 through a bearing; an ingot lifting knife 336 is fixedly mounted at the front end of the hollow straight tube 332, and is located at the lower side of the main rotating roller 335; a spray hole 337 is provided on the surface of the ingot lifting knife 336, and the spray hole 337 is connected to the hollow straight tube 332; the ingot lifting end of the ingot lifting knife 336 is fitted into the crystallization wheel groove 4101 of the crystallization wheel 41 to realize demoulding of the copper ingot.

[0050] In order to facilitate the guidance of the demoulding copper ingot and make it enter the next process, a bridge assembly 32 is also included, and the bridge assembly 32 is composed of a plurality of unit bridge members 321. Specifically, the unit bridge member 321 includes a bridge groove 3211, and a hollow notch 3212 is provided at the bottom of the bridge groove 3211; a guide rotating cylinder 3213, which can be rotatably arranged in the bridge groove 3211 and located at the hollow notch 3212; a collection groove 3214, which is fixedly arranged below the hollow notch 3212, and a collection box 3215 can be pulled out and arranged in the collection groove 3214. Specifically, the guide rotating cylinder 3213 includes a shaft body, two bearings sleeved on the shaft body, and a cylinder sleeved on the two bearings. The guide rotating cylinder 3213 of the bridge assembly cooperates with the collection box 3215 to synchronously collect oxidized debris when conveying the copper ingot.

[0051] In order to adjust the approach bridge assembly so that it can cooperate with the ingot assembly, the frame 1 is provided with an approach bridge adjustment member, which includes an approach bridge rotating shaft 323, which is rotatably arranged in the frame 1 through an approach bridge bearing seat 325, one end of which passes through the frame 1 and is fixedly connected to the approach bridge rotating shaft 323 through a kit 326; an approach bridge adjustment hydraulic cylinder 322 is fixedly arranged inside the frame 1, and the movable end of the approach bridge adjustment hydraulic cylinder 322 is hingedly provided with an approach bridge support arm 324, and the other end of the approach bridge support arm 324 is fixedly sleeved on the approach bridge rotating shaft 323. The approach bridge adjustment hydraulic cylinder 322 drives the linkage design of the approach bridge support arm 324 to realize the dynamic adjustment of the conveying angle and adapt to different production rhythm requirements.

[0052] 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 to drive 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 tube 332 to form a water film lubrication interface to separate the copper ingot 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 driving 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, and the worn ingot lifting assembly 33 can be directly replaced after the shield 34 is disassembled, without stopping the machine to disassemble 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.

[0053] This mechanism integrates the spray hole 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 driving rod, so that the ingot lifting knife can be independently adjusted along the axial direction. In case of local wear, only the position of the ingot lifting knife needs to be adjusted to replace the ingot lifting assembly separately, which reduces the maintenance time. The main rotating drum is connected to the support rod through the 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 hole, the wear rate of the crystallization wheel groove is reduced, and the service life of the equipment is extended. The guide rotating cylinder of the approach bridge assembly cooperates with the collection box to collect oxidized debris synchronously 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.

Through the multi-directionally arranged cooling pipe group 47, all-round and uniform cooling of the crystallization wheel groove 4101 and the inside and outside of the steel strip is achieved, effectively suppressing the internal stress concentration of the copper rod and improving the grain refinement. Preferably, the third main cooling spray pipe 4705 sprays directional spray on the front side groove wall of the crystallization wheel groove, which can accurately adjust the temperature gradient at the crystallization front and avoid surface defects caused by local overcooling.

[0057] The steel belt 411 is sleeved on the steel belt wheel assembly and is used to form a crystallization channel 400 with the crystallization wheel groove 4101 on the outer side wall of the crystallization wheel 41 .

[0058] 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 avoid leakage of copper liquid, a first swing mechanism 49 is further provided inside the frame 1, and the first swing mechanism 49 includes a swing fixing plate 4901, which is fixedly arranged on the side of the frame 1, and a swing through groove 4902 is provided on the swing fixing plate 4901; the swing through groove 4902 is a rectangular groove; a first rotating arm 4904, one end of the first rotating arm 4904 is hinged to one end of the swing fixing plate 4901; the other end of the first rotating arm 4904 is provided with a hollow rotating sleeve 4905, and the rotating shaft of the second steel belt pulley 45 is rotatably inserted in the hollow rotating sleeve 4905; a first hydraulic cylinder 4903, the first hydraulic cylinder 4903 is built in the frame 1, and the movable end of the first hydraulic cylinder 4903 passes through the frame 1 and the swing through groove 4902, and is connected to the first rotating arm 4904 through a hinge seat.

[0059] In order to ensure the sealing of the crystallization channel 400 when the copper liquid is cast, a second swing mechanism 48 is also provided inside the frame 1, and the second swing mechanism 48 includes a central connecting shaft 4803, and the central connecting shaft 4803 is arranged to penetrate the frame 1 as a whole, and 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 in 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.
