Description

Technical Field

[0001] The present invention relates to the technical field of continuous casting equipment, in particular to a high-efficiency metal parts continuous casting equipment and a working method. Background Art

[0002] The continuous casting process is a production process in which refined molten steel is continuously cast into billets. During this process, the molten steel undergoes a series of treatments and cooling, and ultimately solidifies into billets of specific shapes and sizes. Continuous casting methods mainly include horizontal continuous casting, arc continuous casting, and vertical continuous casting. Horizontal continuous casting is characterized by the horizontal injection of molten steel into a horizontally placed crystallizer, where the billets solidify and are pulled out in a horizontal state. This makes it suitable for the production of round tube billets, square billets, and the like. The existing technologies involved in horizontal continuous casting are as follows:

[0003] 1. Publication No. CN114505457B discloses a horizontal continuous casting system and a foam steel production process. The horizontal continuous casting system includes a ladle, an electrode heating device, a horizontal continuous casting device, and an electromagnetic stirring system. The present invention can produce foam steel with a porosity of 1% to 90%, has a short process flow, a high yield rate, and high production efficiency, and can realize continuous casting of square and round billets. The foam steel produced by continuous casting has a high metal frame strength that can meet the requirements of subsequent deep processing.

[0004] 2. Publication No. CN113680980B discloses a production process for a copper-manganese alloy using horizontal continuous casting, specifically comprising: batching; initial casting (initial furnace charging, initial smelting, refining and degassing, casting, pouring, and cooling of the ingot); and continuous casting. The overall process design of the present invention is rational, and the copper-manganese alloy prepared has uniform composition and good consistency, a dense structure, few pores and inclusions, and no defects such as macroscopic and microscopic segregation. Furthermore, the horizontal continuous casting method employed by the present invention enables large-scale production, and the entire process has the advantages of stable process, simple operation, and low melting and casting production costs.

[0005] 3. A secondary cooling device and method for a continuous casting machine, disclosed in Publication No. CN103842113B, comprises multiple pairs of support rollers and multiple nozzles, each support roller having multiple roller sections divided along the width of the strand and grooves disposed between the roller sections. The grooves disposed on the upstream and downstream support rollers, adjacent to each other along the conveying direction, are staggered relative to each other along the width. A first nozzle of the multiple nozzles is disposed at a first nozzle position defined between the roller section of the upstream support roller and the groove of the downstream support roller.

[0006] In the above-mentioned prior art, when the cast product is pulled out of the crystallizer for secondary cooling, only the nozzle setting position has a higher cooling effect. Due to temperature transfer, the high temperature of the ingot causes the cooling water adhering to the ingot to also have a higher temperature. Therefore, the cooling effect of the position where the nozzle is not aligned is poor. At the same time, it does not have the function of quality inspection after secondary cooling, lacks an immediate quality feedback mechanism, and relies on offline quality inspection of the final product to evaluate product quality. Unqualified products often need to be identified and processed in subsequent quality inspection links, lagging behind the production process, making it difficult to discover problems in production in time, easily causing the continuous casting device to operate in an abnormal state, missing the best opportunity to adjust process parameters in time and avoid defect expansion in the production process, resulting in waste of resources and cost increase, affecting production efficiency. In view of this, in-depth research on the above-mentioned problems led to the emergence of this case. Summary of the Invention

[0007] The purpose of the present invention is to solve the above problems. A high-efficiency continuous casting equipment and working method for metal parts are designed, which solves the problem that when the cast product is pulled out of the crystallizer for secondary cooling, only the nozzle setting position has a higher cooling effect. Due to temperature transfer, the high temperature of the ingot causes the cooling water adhering to the ingot to also have a higher temperature. Therefore, the cooling effect of the position where the nozzle is not aligned is poor. At the same time, it does not have the function of quality inspection after secondary cooling, and lacks an immediate quality feedback mechanism. It relies on offline quality inspection of the final product to evaluate product quality. Unqualified products often need to be identified and processed in subsequent quality inspection links, lagging behind the production process, making it difficult to discover problems in production in time, easily causing the continuous casting device to operate in an abnormal state, missing the best time to adjust process parameters in time and avoid defect expansion in the production process, resulting in waste of resources and cost increase, affecting production efficiency.

[0047] The present invention will be described in detail below with reference to the accompanying drawings. Figure 1-9 As shown, a high-efficiency continuous casting equipment and working method for metal parts.

[0048] Through the use of wires by those skilled in the art, all electrical components in this case are connected to their corresponding power supplies, and appropriate controllers should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, in which the electrical components are electrically connected in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0049] Example 1:

[0050] A high-efficiency continuous casting device for metal parts includes a base 1, a crystallizer 2 and a casting machine 3 are arranged on the base 1, a controller 8 is also arranged on the base 1, and a secondary cold detector is arranged on the base 1 and located between the crystallizer 2 and the casting machine 3;

[0051] Specifically, the crystallizer 2 and the casting machine 3 are prior art. The specific structure and working principle of the crystallizer 2 and the casting machine 3 can be referred to the crystallizer 2 and the casting machine 3 in the high-precision copper strip horizontal continuous casting unit automation equipment with publication number CN117415292B. The controller 8 has a built-in single-chip microcomputer, which can be software-programmed to achieve control of the equipment by writing a control program. Since the above content is prior art, it will not be described in detail.

[0052] The molten metal is poured into the crystallizer 2, which causes the metal to gradually solidify from the outside to the inside, forming a metal billet shell with a certain strength and shape. The initially solidified billet is smoothly pulled out of the crystallizer 2 through the work of the billet puller 3. During the process of the billet being pulled out, it passes through the secondary cold detector located between the crystallizer 2 and the billet puller 3. The secondary cold detector further cools the billet to ensure that the inside of the billet is completely solidified. At the same time, the quality of the billet is monitored in real time. Once a non-standard situation is detected, the horizontal continuous casting equipment stops working, and the unqualified billets are sampled and sent for inspection through the secondary cold detector, so that the staff can understand the continuous casting working status in time, find and solve problems in time, prevent the equipment from continuing production in an abnormal state, and improve production efficiency.

[0053] In the specific implementation process, the secondary cold detector includes a working box 4 and a cutter 7. The working box 4 is set on the base 1 and is located on one side of the crystallizer 2. A contact cooler 5 is set inside the working box 4. A detector 6 is set inside the working box 4 and on one side of the contact cooler 5. The cutter 7 is set outside the end of the working box 4 close to the detector 6. The casting machine 3 is set on one side of the cutter 7. A through hole 401 is provided on the side wall of the working box 4.

[0054] Specifically, after the billet is pulled out of the crystallizer 2, it passes through the contact cooler 5 for cooling, and then passes through the detector 6, which monitors the quality of the billet in real time. The cutter 7 is used to cut and send unqualified billets for inspection;

[0055] In a specific implementation process, the contact cooler 5 includes a bottom contact unit and a top contact unit. The bottom contact unit and the top contact unit are installed symmetrically up and down, and a first hydraulic cylinder 501 is provided between the bottom contact unit and the top contact unit. The bottom contact unit is installed on the inner bottom surface of the working box 4. The bottom contact unit and the top contact unit have the same structure. The bottom contact unit passes through the side wall of the working box 4, and the top contact unit passes through the through hole 401.

[0056] Specifically, by contracting the first hydraulic cylinder 501, the distance between the bottom contact unit and the top contact unit can be adjusted, so that the bottom contact unit and the top contact unit can be used for casting billets of different thicknesses, with a wide range of applications;

[0057] In a specific implementation process, the bottom contact unit and the top contact unit both include a support structure, on which a plurality of rotating rods 502 are movably inserted at equal intervals, and a delivery sleeve 503 is installed at one end of each of the rotating rods 502. A plurality of annular grooves 504 are arranged at equal intervals on the delivery sleeve 503, and the plurality of annular grooves 504 on two adjacent delivery sleeves 503 are staggered. A blocking cover 506 is sleeved on one end of the delivery sleeve 503 through a first sealing bearing 505, and a water pipe 507 is inserted at the center of the blocking cover 506. A plurality of spray assemblies are installed on the water pipe 507, and the plurality of spray assemblies and the plurality of annular grooves 504 are arranged corresponding to each other;

[0058] Specifically, cooling water flows through the water pipe 507, and the cooling water can be sprayed onto the ingot through multiple spraying assemblies. The annular groove 504 forms a certain distance between the spraying assembly and the surface of the ingot, leaving space for spraying the cooling water. At the same time, the side walls of the groove also allow the cooling water to be sprayed on the surface of the ingot in a targeted manner, preventing the cooling water from diffusing to the outside when spraying on the surface of the ingot. Since multiple annular grooves 504 are staggered on the two adjacent conveying sleeves 503, when the ingot passes through the bottom contact unit and the top contact unit, it is in contact with the cooling water sprayed by the spraying assembly, thereby ensuring the cooling quality.

[0059] In a specific implementation, each spray assembly includes four nozzles 508, which are inserted into the annular groove 504 in a circular array. A ring tube 509 is installed at one end of the four nozzles 508. The two ends of the ring tube 509 are movably sleeved on the water pipe 507 through a second sealed bearing 510. Multiple water outlets 511 are opened on the ring tube 509 and the water pipe 507.

[0060] Specifically, cooling water flows through the water pipe 507 , and the cooling water enters the space between the ring tube 509 and the second sealed bearing 510 from the multiple water outlets 511 on the water pipe 507 , and then flows out of the ring tube 509 from the multiple water outlets 511 on the ring tube 509 and is sprayed out from the four nozzles 508 ;

[0061] In the specific implementation process, the water inlet pipe 512 and the water outlet pipe 513 are respectively inserted on the blocking cover 506 and located on the upper and lower sides of the water pipe 507. The water inlet pipe 512 and the water outlet pipe 513 are both installed with a circulation connecting pipe 514 at one end, and the water supply connecting pipe 515 is installed at one end of the water pipe 507.

[0062] Specifically, the water supply connecting pipe 515 is connected to the circulating connecting pipe 514 on the water inlet pipe 512 to the cold water supply system to provide cooling water for the water pipe 507. Under the sealing of the first sealed bearing 505, the conveying sleeve 503 and the plugging cover 506 are in a sealed state. The cooling water enters the water inlet pipe 512 through the circulating connecting pipe 514, filling the space between the conveying sleeve 503 and the plugging cover 506, so that the conveying sleeve 503 as a whole is in a low-temperature environment, and the low temperature is transferred to the ingot to cool the ingot. The circulating connecting pipe 514 on the water outlet pipe 513 is connected to the cold water collection system to discharge the cooling water in the space between the conveying sleeve 503 and the plugging cover 506 to ensure the low-temperature effect. The cold water collection system and the cold water supply system can be connected to each other, such as a cooling water circulation device with publication number CN105441311B, to save water resources. Since it is a prior art, it will not be described in detail here.

[0063] In a specific implementation, the support structure includes a first fixed plate 516 and a second fixed plate 517. Multiple rotating rods 502 are movably inserted into the first fixed plate 516. Multiple connecting rods 518 are inserted into the first fixed plate 516 at equal intervals. The multiple connecting rods 518 are fixedly sleeved with connecting gears 519. The multiple rotating rods 502 are fixedly sleeved with driving gears 520. The connecting gears 519 and the driving gears 520 are engaged with each other. The water pipe 507, the water inlet pipe 512 and the water outlet pipe 513 are fixedly inserted into the second fixed plate 517. A motor 521 is installed on the first fixed plate 516. The driving end of the motor 521 is installed at one end of one of the multiple rotating rods 502.

[0064] Specifically, the motor 521 rotates the rotating rods 502. Under the meshing of the driving gear 520 and the connecting gear 519, the multiple rotating rods 502 rotate simultaneously, and the conveying sleeve 503 rotates at one end of the blocking cover 506 through the first sealed bearing 505 to convey the ingot. It should be noted that the rotational working state of the conveying sleeve 503 matches the moving state of the ingot. When the conveying sleeve 503 rotates, the nozzle 508 inserted in the annular groove 504 also rotates. The nozzle 508 drives the ring tube 509 to rotate around the water pipe 507 through the seal of the second sealed bearing 510.

[0065] In a specific implementation, the detector 6 includes a shielding plate 601, a rectangular notch 602 is opened on the shielding plate 601, corresponding to the position between the bottom contact unit and the top contact unit, a connecting frame is installed on the shielding plate 601, a first cylinder 603 is installed on the lower wall of the connecting frame, and an eddy current flaw detector 604 is installed at the telescopic end of the first cylinder 603;

[0066] Specifically, by adjusting the extension and contraction of the first cylinder 603, the distance between the eddy current flaw detector 604 and the billet meets the working requirements of the eddy current flaw detector 604. The billet passes between the bottom contact unit and the top contact unit structure, and then passes through the rectangular notch 602 to move to the eddy current flaw detector 604. The eddy current flaw detector 604 detects the billet. The connecting frame is used for fixing the first cylinder 603 and the baffle 601.

[0067] In a specific implementation process, the cutter 7 includes a mobile structure, on which a C-shaped frame 701 is mounted, on which three clamping assemblies are mounted, and a cutting assembly is mounted on the inner top surface of the C-shaped frame 701 and between two adjacent clamping assemblies;

[0068] Specifically, the time interval between detection of an abnormality and device shutdown is preset. That is, after the eddy current flaw detector 604 detects an abnormality in the quality of the ingot, the device stops working after the time interval has passed. At this time, the area with the abnormal quality of the ingot moves to the middle clamping assembly among the three clamping assemblies.

[0069] In the specific implementation process, each clamping assembly includes two second cylinders 702, which are symmetrically installed on the upper and lower opposite walls inside the C-shaped frame 701, and the telescopic ends of the two second cylinders 702 are installed with clamping plates 703;

[0070] In the specific implementation process, the cutting assembly includes a screw module 704, which is installed on the inner bottom surface of the C-shaped frame 701. A third cylinder 705 is installed on the movable end of the screw module 704, and a laser cutting instrument 706 is installed on the telescopic end of the third cylinder 705;

[0071] Specifically, the second cylinder 702 is extended to hold the clamping plate 703 on the ingot, and the third cylinder 705 is contracted to keep the distance between the laser cutting instrument 706 and the ingot within a normal working size. The screw module 704 is driven to move the third cylinder 705 and the laser cutting instrument 706, and the laser cutting instrument 706 is operated to cut the ingot, cutting off the area with abnormal quality.

[0072] In a specific implementation process, the mobile structure includes a robot mobile chassis 707, on which four Mecanum wheels 708 are symmetrically arranged in pairs, a second hydraulic cylinder 709 is installed on the robot mobile chassis 707, and a C-frame 701 is installed on the telescopic end of the second hydraulic cylinder 709;

[0073] Specifically, the moving path of the robot mobile chassis 707 is pre-set so that the cutter 7 can travel back and forth between the working area and the designated position for detecting metal quality problems. For details, please refer to the path setting of the sweeping robot. Since it is a prior art, it will not be described in detail. When the cutting assembly is completed, the clamping assemblies at both ends work, that is, the second cylinder 702 contracts, so that the clamping plate 703 leaves the billet. At this time, the clamping assembly in the middle still clamps the billet segment with abnormal quality, and the Mecanum wheel 708 works to move the cutter 7 and transport the billet segment to the designated position. There is no need for staff to collect it in person, which is convenient to use.

[0074] In the specific implementation process, as an advantage, further, a counterweight block 710 is provided on the robot mobile chassis 707 to counterweight the robot mobile chassis 707 and prevent the cutter 7 from tilting;

[0075] In the specific implementation process, as a preferred embodiment, further, both ends of the working box 4 are equipped with split door 402 for shielding the openings at both ends of the working box 4, and the split door 402 is provided with an avoidance opening 403 for the passage of the billet;

[0076] Example 2:

[0077] A working method comprising the following working steps:

[0078] Step 1: Molten metal is poured into the crystallizer 2, which gradually solidifies the metal from the outside to the inside, forming a metal casting shell with a certain strength and shape;

[0079] Step 2: The casting machine 3 works to smoothly pull the initially solidified casting from the crystallizer 2;

[0080] Step 3: After the ingot is pulled out, it first passes through the contact cooler 5, which cools the ingot through the bottom contact unit and the top contact unit;

[0081] Step 4: The billet passes through the detector 6, which uses the eddy current flaw detector 604 to detect the billet. The distance between the eddy current flaw detector 604 and the billet is adjusted to meet the working requirements by adjusting the extension and contraction of the first cylinder 603;

[0082] Step 5: If the eddy current flaw detector 604 detects that the quality of the ingot is abnormal, the device will stop working after a preset time;

[0083] Step 6: After the equipment stops working, the area of ​​the billet with abnormal quality moves to the middle part of the three clamping assemblies. The second cylinder 702 is extended to clamp the clamping plate 703 on the billet. The laser cutting instrument 706 cuts the billet through the operation of the third cylinder 705 and the screw module 704, cutting off the area with abnormal quality.

[0084] Step 7: The clamping assemblies at both ends release the ingot, while the clamping assemblies in the middle still hold the ingot segment with abnormal quality.

[0085] Step 8: The cutter and conveyor 7 moves as a whole to transport the ingot segments with abnormal quality to a designated location for inspection.

[0086] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Any changes that may be made to certain parts thereof by those skilled in the art all reflect the principles of the present invention and fall within the scope of protection of the present invention.
