Description

Technical Field

[0001] This invention relates to the field of molten iron filling and return transfer technology, specifically an automatic molten iron filling and return transfer system. Background Technology

[0002] In metallurgical production sites, molten iron transfer, filling, and remelting are indispensable core processes. The specific process is as follows: after the molten iron melts in the electric furnace, it is first poured into a ladle. Then, the ladle is transferred to the casting machine by a crane or forklift. Subsequently, the crane lifts the ladle and raises it to the inlet of the casting machine. Finally, the ladle is tilted by manually rotating the lifting wheel, completing the filling of molten iron into the casting machine.

[0003] When the temperature of the molten iron in the casting machine drops or the equipment needs maintenance, the molten iron in the casting machine must be poured back into the ladle. Then, a forklift or overhead crane will transport the ladle to the electric furnace. The overhead crane will lift the ladle with a hoist and raise it to the furnace opening. The ladle will then be tilted by manually rotating the hoist wheel to pour the molten iron into the electric furnace for reheating.

[0004] The entire process of molten iron transfer, filling, and return to the furnace is mainly carried out manually. The operation is highly dependent on the experience of the operators. The operators need to participate in the entire process of molten iron ladle transfer assistance, hoisting operation, and tilting control. Once a misjudgment or non-standard action occurs during the operation, it is very easy to cause safety accidents such as molten iron splashing and ladle tilting, which threaten the personal safety of the operators.

[0005] Meanwhile, manual operation is inefficient, which not only consumes a lot of human resources and increases the production cost of enterprises, but also increases the temperature loss of molten iron due to slow transfer speed, thereby increasing the energy consumption of enterprises and making it difficult to meet the production needs of enterprises for high efficiency, safety and energy saving.

[0006] In view of the above, this application is hereby submitted. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides an automatic molten iron filling and return transfer system to solve the problems mentioned in the background section.

[0008] To achieve the above objectives, the present invention provides the following technical solution: An automated molten iron filling and return transfer system includes a multi-functional tilting car, a multi-functional furnace car, a ladle, a casting machine, an electric furnace, and a track.

[0009] Both the multi-functional tilting car and the multi-functional furnace front car are mounted on tracks, and can travel along the tracks, move laterally, rotate, lift, and grab molten iron ladles.

[0010] The multi-functional furnace front car is equipped with a roller conveyor and a weighing mechanism, which can receive the molten iron from the electric furnace and measure the weight of the molten iron.

[0011] The multi-functional tilting car can dock with the multi-functional furnace front car to transfer molten iron ladles and add molten iron to the casting machine.

[0012] When molten iron is returned to the furnace, the multi-functional tilting car receives the molten iron from the casting machine and transfers it to the multi-functional furnace front car, which then pours the molten iron back into the electric furnace.

[0013] Both the multi-functional tilting car and the multi-functional furnace front car are equipped with a rotating mechanism, a lifting mechanism, and a lifting arm. The rotating mechanism can drive the lifting arm to rotate, the lifting mechanism can drive the lifting arm to rise and fall, and the lifting arm can grab the molten iron ladle.

[0014] The multi-functional tilting car and the multi-functional furnace front car are equipped with a roller conveyor mechanism and a tilting mechanism. The roller conveyor mechanism can drive the molten iron ladle to move on the multi-functional furnace front car, and the tilting mechanism can drive the molten iron ladle to tilt, so as to pour out the molten iron.

[0015] The track is equipped with a limiting mechanism and an anti-collision structure. The limiting mechanism can limit the movement of the multi-functional tilting car and the multi-functional furnace front car, and the anti-collision structure can prevent the two cars from colliding when they move on the track.

[0016] Preferably, a ladle cover dust removal mechanism is provided at the ladle opening. The ladle cover dust removal mechanism includes a ladle cover and a mechanical pressing structure. A dust guiding channel is provided on the ladle cover, and a dust collector is connected to the dust guiding channel.

[0017] The ladle cover dust removal mechanism is compatible with the ladle opening of the molten iron ladle. The mechanical clamping structure ensures that the ladle cover and the ladle opening fit tightly during the transfer and pouring of molten iron, preventing the leakage of smoke and dust caused by splashing molten iron. The dust guide channel can efficiently collect the smoke and dust and guide it into the dust collector, realizing centralized treatment of smoke and dust, reducing the impact on the working environment and operators. At the same time, the ladle cover can play a certain role in heat preservation of molten iron, reducing the temperature loss of molten iron.

[0018] Preferably, the casting machine is provided with a casting port, and a metering component is provided on the side of the casting port. The metering component includes a control component and an adjustment component.

[0019] The quantitative component precisely connects with the pouring gate, allowing for flexible adjustment of the molten iron pouring amount according to pouring requirements. The control component is responsible for starting and stopping the molten iron pouring and basic quantitative control, while the adjustment component can fine-tune and calibrate the quantitative parameters to ensure the accuracy and stability of the molten iron pouring, avoid affecting the casting quality due to pouring amount deviation, reduce molten iron waste, and improve production efficiency.

[0020] Preferably, the control component includes a control airbag, a heat-conducting rod, an adjusting rod, a sealing baffle, and a return spring. One end of the control airbag is fixedly connected to the outside of the pouring gate. The top end of the heat-conducting rod is inserted into the connection between the control airbag and the pouring gate. The adjusting rod is slidably connected to the outside of the pouring gate. The movable end of the control airbag is fixedly connected to the adjusting rod. One end of the adjusting rod is provided with a return spring. The other end of the return spring is fixedly connected to the pouring gate. The return spring and the adjusting rod are coaxially arranged. One end of the sealing baffle is rotatably connected to one side of the bottom surface of the pouring gate. The side of the adjusting rod is connected to the other end of the sealing baffle via a steel cable.

[0021] The components of the control unit work together in concert. The heat-conducting rod can sense the temperature of the molten iron at the pouring gate in real time, thereby triggering the extension and retraction of the control airbag. The control airbag drives the adjusting rod to slide along the outside of the pouring gate. The adjusting rod pulls the closed baffle to rotate through the steel cable, realizing the opening and closing control of the pouring gate. The reset spring can drive the adjusting rod and the closed baffle to return to the initial position when the control airbag resets, ensuring the stable operation of the control unit and ensuring the continuity of quantitative molten iron pouring.

[0022] Preferably, the adjusting component includes a mounting bracket, an adjusting ring, and a heat-conducting sleeve. The mounting bracket is fixedly connected to the side of the pouring gate, and a through hole is provided on the mounting bracket. The adjusting ring is rotatably connected to the mounting bracket. The heat-conducting sleeve is slidably fitted onto the outer wall of the heat-conducting rod, and the heat-conducting sleeve passes through the through hole and is threadedly connected to the adjusting ring.

[0023] The adjustment component is securely mounted on the side of the pouring gate via a mounting bracket. The perforation provides guidance for the vertical sliding of the heat-conducting sleeve. When the adjustment ring is rotated, the heat-conducting sleeve is moved vertically along the heat-conducting rod by the threaded drive, thereby adjusting the contact range between the heat-conducting sleeve and the heat-conducting rod and realizing the adjustment of the heat conduction sensitivity. The triggering time of the control component can be precisely controlled according to the temperature requirements of different pouring scenarios, further improving the accuracy of quantitative pouring of molten iron.

[0024] Preferably, the heat-conducting rod is made of a high-temperature resistant heat-conducting material, and its top end is fixed to the control airbag in a close fit.

[0025] The high-temperature resistant thermally conductive material ensures that the heat-conducting rod works stably in the high-temperature environment of molten iron, and is not prone to deformation or damage. At the same time, it can efficiently transmit the temperature signal at the pouring gate. The close-fitting fixing method can increase the contact area between the heat-conducting rod and the control air bag, reduce temperature transmission loss, ensure that the control air bag can detect temperature changes in a timely and accurate manner, and ensure the response sensitivity of the control components.

[0026] Preferably, the side of the closed baffle near the pouring port is provided with a fire-resistant sealing layer, and when the closed baffle is fully closed, its edge is tightly fitted with the bottom surface of the pouring port.

[0027] The refractory sealing layer can resist the high-temperature corrosion of molten iron, prevent the sealing baffle from being damaged by high temperature, and at the same time improve the sealing performance between the sealing baffle and the bottom surface of the pouring gate, prevent molten iron from leaking from the gaps, and ensure the sealing performance when the pouring gate is closed. This not only prevents the waste of molten iron, but also ensures operational safety. The tightly fitting structural design can further improve the sealing effect and adapt to the pouring needs under different working conditions.

[0028] Preferably, the inner wall of the adjusting ring is provided with a heat insulation pad, the outer wall of the adjusting ring is provided with anti-slip texture, and the bottom surface of the adjusting ring is connected to the mounting bracket with damping rotation.

[0029] The heat insulation pad can block the high temperature transmitted by the heat-conducting sleeve, preventing operators from being burned during adjustment, while protecting the internal thread structure of the adjusting ring and preventing high temperature from affecting its transmission performance; the anti-slip texture can increase the friction between the operator's hand and the adjusting ring, making it easier to rotate and adjust, and improving the convenience of operation.

[0030] Damped rotary connections allow the adjusting ring to maintain a stable position after adjustment, preventing it from loosening due to vibration or other factors, thus ensuring the stability of the adjustment parameters.

[0031] Preferably, the outer wall of the heat-conducting rod is fitted with a heat-insulating sleeve, the top end of the heat-insulating sleeve extends to the connection between the control airbag and the pouring port, and the bottom end of the heat-insulating sleeve is higher than the bottom end of the heat-conducting rod.

[0032] The heat insulation sleeve effectively protects the heat-conducting rod, reducing heat loss to the surrounding environment and ensuring concentrated heat transfer to the control airbag, thus improving the accuracy of temperature sensing. It also prevents surrounding components from being damaged by high temperatures. The design extending to the connection between the control airbag and the pouring gate further prevents the high temperature at the pouring gate from directly affecting the control airbag, extending its service life.

[0033] Preferably, a clamp is provided on the side of the pouring port, the clamp is arranged horizontally, and the adjusting rod is slidably connected in the clamp.

[0034] The clamp provides stable sliding support for the adjusting rod. The horizontally arranged structure ensures that the adjusting rod slides smoothly in the horizontal direction, avoiding deviation or shaking during the sliding process. This ensures the stability of the connection between the adjusting rod and the steel cable and control airbag, thereby ensuring that the opening and closing action of the closed baffle is precise and controllable, and providing structural protection for the quantitative injection of molten iron.

[0035] Compared with the prior art, the present invention provides an automatic molten iron filling and return transfer system, which has the following advantages: In this invention, no manual on-site operation is required throughout the entire process, replacing the high-risk operations such as manual driving, manual grabbing, and manual control of tipping in traditional molten iron transfer. This avoids safety accidents such as burns and splashes that may occur when operators come into contact with high-temperature molten iron, eliminates safety hazards caused by human error during transfer, and ensures the personal safety of operators. At the same time, the limiting mechanism and anti-collision structure set on the track further regulate the running trajectory of the two vehicles and prevent problems such as collision between the two vehicles and workstation deviation.

[0036] In this invention, the multi-functional tilting trolley and the multi-functional furnace front trolley can travel quickly along the track and have multiple functions such as lateral movement, rotation, and lifting. They can quickly complete actions such as grabbing, transferring, docking, filling, and returning molten iron ladles to the furnace, significantly shortening the molten iron transfer cycle and increasing the molten iron transfer speed. Compared with traditional forklifts and manual transfer methods, it avoids the cumbersome process and waiting time of manual operation, and achieves seamless connection of molten iron receiving, transferring, filling, and returning to the furnace. It effectively reduces the loss of molten iron temperature drop, avoids production interruption caused by untimely molten iron transfer, ensures the continuity of casting production and electric furnace smelting, and can realize the recycling of molten iron ladles, improve the utilization rate of molten iron ladles, and further improve the overall production efficiency. Similar intelligent molten iron transportation systems can greatly improve the turnover rate of molten iron ladles and provide support for optimizing the production cycle of enterprises.

[0037] In this invention, the multi-functional tilting car, the multi-functional furnace front car and the track are used to realize the convenient transfer of molten iron between the casting machine and the electric furnace. There is no need for frequent manual handling of molten iron ladles, which greatly reduces the intensity of manual labor. At the same time, the quantitative component at the casting port can realize the precise control of the amount of molten iron added, avoiding the waste or insufficient addition of molten iron caused by manual addition, and improving the standardization and efficiency of molten iron addition.

[0038] In this invention, a quantitative component consisting of a control component and an adjustment component is set up. The structure is simple and does not require complex electrical control. Heat is transferred through a heat-conducting rod to drive the control airbag to move, which in turn drives the closed baffle switch to achieve automated control of quantitative filling. The adjustment component can adjust the filling amount by rotating the adjustment ring. It is easy to operate, adaptable to different molten iron filling needs, and highly practical.

[0039] In this invention, the reset spring and the adjusting rod are coaxially arranged in the control component, which can ensure that the adjusting rod slides smoothly and avoids jamming, while ensuring the accurate reset of the closed baffle and effectively preventing molten iron leakage; the heat-conducting sleeve in the adjusting component can only slide vertically, ensuring that the rotation of the adjusting ring can be accurately converted into the movement of the heat-conducting sleeve, thus ensuring the adjustment accuracy.

[0046] The multi-functional furnace front car 2 is equipped with a roller conveyor and a weighing mechanism, which can receive the molten iron from the electric furnace 5 and measure the weight of the molten iron.

[0047] The multi-functional tilting car 1 can dock with the multi-functional furnace front car 2 to transfer the molten iron ladle 3 and add molten iron to the casting machine 4.

[0048] When molten iron is returned to the furnace, the multi-functional tilting car 1 receives the molten iron from the casting machine 4 and transfers it to the multi-functional furnace front car 2, which then pours the molten iron back into the electric furnace 5.

[0049] Both the multi-functional tilting car 1 and the multi-functional furnace front car 2 are equipped with a rotating mechanism, a lifting mechanism, and a lifting arm. The rotating mechanism can drive the lifting arm to rotate, the lifting mechanism can drive the lifting arm to rise and fall, and the lifting arm can grab the molten iron ladle 3.

[0050] The multi-functional tilting car 1 and the multi-functional furnace front car 2 are equipped with a roller conveyor mechanism and a tilting mechanism.

[0051] Track 6 is equipped with a limiting mechanism and an anti-collision structure. The limiting mechanism can restrict the movement of the multi-functional tilting car 1 and the multi-functional furnace front car 2, and the anti-collision structure can prevent the two cars from colliding when they move on track 6.

[0052] In this invention, no manual on-site operation is required throughout the entire process, replacing the high-risk operations such as manual driving, manual grabbing, and manual control of tipping in traditional molten iron transfer. This avoids safety accidents such as burns and splashes that may occur when operators come into contact with high-temperature molten iron, eliminates safety hazards caused by human error during transfer, and ensures the personal safety of operators. At the same time, the limiting mechanism and anti-collision structure set on track 6 further regulate the running trajectory of the two cars and prevent problems such as collision between the two cars and workstation deviation.

[0053] Combined with the equipment's own automated protection design, the safety of molten iron transfer, filling and remelting operations has been comprehensively improved, practicing the company's inherent safety concept. Automated operation reduces the exposure time of personnel in high temperature and dusty environments, improves the working environment and reduces occupational health risks.

[0054] In this invention, the multi-functional tilting car 1 and the multi-functional furnace front car 2 can travel quickly along the track 6 and have multiple functions such as lateral movement, rotation, and lifting. They can quickly complete actions such as grabbing, transferring, docking, filling, and returning molten iron ladles, which greatly shortens the molten iron transfer cycle and improves the molten iron transfer speed. Compared with traditional forklifts and manual transfer methods, it avoids the cumbersome process and waiting time of manual operation, and realizes the seamless connection of molten iron receiving, transferring, filling, and returning to the furnace. It effectively reduces the loss of molten iron temperature drop, avoids production interruption caused by untimely molten iron transfer, ensures the continuity of casting production and electric furnace smelting, and can realize the recycling of molten iron ladles, improve the utilization rate of molten iron ladles, and further improve the overall production efficiency. Similar intelligent molten iron transportation systems can greatly improve the turnover rate of molten iron ladles and provide support for optimizing the production cycle of enterprises.

[0055] Preferably, a ladle cover dust removal mechanism is provided at the ladle opening of the molten iron ladle 3. The ladle cover dust removal mechanism includes a ladle cover and a mechanical pressing structure. A dust guiding channel is provided on the ladle cover, and a dust collector is connected to the dust guiding channel.

[0056] The ladle cover dust removal mechanism is compatible with the ladle opening of molten iron ladle 3. The mechanical clamping structure ensures that the ladle cover and ladle opening fit tightly during the transfer and pouring of molten iron, preventing the leakage of smoke and dust caused by splashing molten iron. The dust guide channel can efficiently collect the smoke and dust and guide it into the dust collector, realizing centralized treatment of smoke and dust, reducing the impact on the working environment and operators. At the same time, the ladle cover can play a certain role in heat preservation of molten iron, reducing the temperature loss of molten iron.

[0057] Preferably, the casting machine 4 is provided with a casting port 7, and a metering component is provided on the side of the casting port 7. The metering component includes a control component and an adjustment component.

[0058] The quantitative component is precisely connected to the pouring port 7, which can flexibly adjust the amount of molten iron added according to the pouring requirements. The control component is responsible for starting and stopping the molten iron addition and basic quantitative control, while the adjustment component can fine-tune and calibrate the quantitative parameters to ensure the accuracy and stability of the molten iron addition, avoid the impact of the addition deviation on the casting quality, reduce molten iron waste, and improve production efficiency.

[0059] Preferably, the control component 8 includes a control airbag 81, a heat-conducting rod 82, an adjusting rod 83, a sealing baffle 84, and a return spring 85. One end of the control airbag 81 is fixedly connected to the outside of the pouring port 7. The top end of the heat-conducting rod 82 is inserted into the connection between the control airbag 81 and the pouring port 7. The adjusting rod 83 is slidably connected to the outside of the pouring port 7. The movable end of the control airbag is fixedly connected to the adjusting rod 83.

The side of the adjusting rod 83 is connected to the other end of the sealing baffle 84 through a steel cable 86.

[0060] All components of the control unit 8 work together. The heat-conducting rod 82 can sense the temperature of the molten iron at the pouring port 7 in real time, thereby triggering the extension and retraction of the control airbag 81. The control airbag 81 drives the adjusting rod 83 to slide along the outside of the pouring port 7. The adjusting rod 83 pulls the closed baffle 84 to rotate through the steel cable 86, thereby realizing the opening and closing control of the pouring port 7. The reset spring 85 can drive the adjusting rod 83 and the closed baffle 84 back to the initial position when the control airbag 81 resets, ensuring the stable operation of the control unit 8 and ensuring the continuity of quantitative molten iron pouring.

[0061] Preferably, the adjusting component 9 includes a mounting bracket 91, an adjusting ring 92, and a heat-conducting sleeve 93. The mounting bracket 91 is fixedly connected to the side of the pouring port 7. A through hole 94 is provided on the mounting bracket 91. The adjusting ring 92 is rotatably connected to the mounting bracket 91. The heat-conducting sleeve 93 is sleeved on the outer wall of the heat-conducting rod 82 and can only slide vertically. The heat-conducting sleeve 93 passes through the through hole 94 and is threadedly connected to the adjusting ring 92.

[0062] The adjusting component 9 is securely mounted on the side of the pouring gate 7 via the mounting bracket 91. The perforation 94 provides guidance for the vertical sliding of the heat-conducting sleeve 93. When the adjusting ring 92 is rotated, the heat-conducting sleeve 93 is driven to move vertically along the heat-conducting rod 82 by means of thread transmission, thereby adjusting the contact range between the heat-conducting sleeve 93 and the heat-conducting rod 82, and realizing the adjustment of the heat conduction sensitivity. The triggering time of the control component 8 can be precisely controlled according to the temperature requirements of different pouring scenarios, further improving the accuracy of quantitative pouring of molten iron.

[0063] Preferably, the heat-conducting rod 82 is made of a high-temperature resistant heat-conducting material, and its top end is fixed to the control airbag 81 in a close fit.

[0064] The high-temperature resistant thermally conductive material ensures that the heat-conducting rod 82 can work stably in the high-temperature environment of molten iron, and is not prone to deformation or damage. At the same time, it can efficiently transmit the temperature signal at the pouring gate 7.

[0065] Preferably, a fire-resistant sealing layer is provided on the side of the closed baffle 84 near the pouring port 7, and when the closed baffle 84 is fully closed, its edge is tightly fitted with the bottom surface of the pouring port 7.

[0066] The refractory sealing layer can resist the high-temperature corrosion of molten iron, prevent the sealing baffle 84 from being damaged by high temperature, and at the same time improve the sealing performance of the sealing baffle 84 and the bottom surface of the pouring port 7, prevent molten iron from leaking from the gap, and ensure the sealing performance when the pouring port 7 is closed. This not only prevents the waste of molten iron, but also ensures the safety of operation. The tightly fitting structural design can further improve the sealing effect and adapt to the pouring needs under different working conditions.

[0067] Preferably, the inner wall of the adjusting ring 92 is provided with a heat insulation pad, the outer wall of the adjusting ring 92 is provided with anti-slip texture, and the bottom surface of the adjusting ring 92 is connected to the mounting bracket 91 with damping rotation.

[0068] The heat insulation pad can block the high temperature transmitted by the heat-conducting sleeve 93, preventing the operator from being burned during adjustment, while protecting the internal thread structure of the adjusting ring 92 and preventing the high temperature from affecting its transmission performance; the anti-slip texture can increase the friction between the operator's hand and the adjusting ring 92, making it easier to rotate and adjust, and improving the convenience of operation.

[0069] The damped rotary connection ensures that the adjusting ring 92 remains in a stable position after adjustment, preventing it from loosening due to vibration or other factors, thus ensuring the stability of the adjustment parameters.

[0070] Preferably, the outer wall of the heat-conducting rod 82 is fitted with a heat-insulating sleeve 87, the top end of the heat-insulating sleeve 87 extends to the connection between the control airbag 81 and the pouring port 7, and the bottom end of the heat-insulating sleeve 87 is higher than the bottom end of the heat-conducting rod 82.

[0071] The heat insulation sleeve 87 can effectively insulate and protect the heat-conducting rod 82, reduce the heat loss of the heat-conducting rod 82 to the surrounding environment, ensure that the heat is concentrated and transferred to the control airbag 81, improve the accuracy of temperature sensing, and prevent surrounding components from being damaged by high temperature. The design extending to the connection between the control airbag 81 and the pouring port 7 can further block the high temperature at the pouring port 7 from directly acting on the control airbag 81, and extend the service life of the control airbag 81.

[0072] Preferably, a clamp 88 is provided on the side of the pouring port 7. The clamp 88 is arranged horizontally, and the adjusting rod 83 is slidably connected in the clamp 88.

[0073] The clamp 88 provides stable sliding support for the adjusting rod 83. The horizontally arranged structure ensures that the adjusting rod 83 slides smoothly in the horizontal direction, avoiding deviation or shaking during the sliding process. This ensures the stability of the connection between the adjusting rod 83 and the steel cable 86 and the control airbag 81, thereby ensuring that the opening and closing action of the closed baffle 84 is precise and controllable, and providing structural protection for the quantitative injection of molten iron.

[0074] The working principle of this device is as follows: After the electric furnace 5 completes the molten iron melting, the multi-functional furnace front car 2 automatically travels along the track 6 to the electric furnace tapping station. The limiting mechanism on the track 6 precisely limits its stopping position to ensure accurate alignment with the electric furnace tapping port.

[0075] Subsequently, the multi-functional furnace front car 2, through its own lifting and rotating mechanisms in conjunction with the lifting arm, grabs the empty molten iron ladle 3 and adjusts it to a receiving posture to receive the molten iron flowing out of the electric furnace 5.

[0076] During this process, the weighing mechanism of the multi-functional furnace front car 2 measures the weight of the molten iron in real time, accurately controls the amount of molten iron to be received, and avoids molten iron overflow or insufficient reception. The measurement data can be fed back to the control system in a synchronous manner to provide data support for the subsequent filling process. At the same time, its roller conveyor mechanism can assist the molten iron ladle 3 in adjusting to the optimal receiving position and improve the receiving stability.

[0077] After the molten iron is received, the multi-functional furnace front car 2 travels along the track 6 to the docking position with the multi-functional tilting car 1. The track limiting mechanism plays its role again to ensure precise docking of the two cars, and the anti-collision structure effectively prevents collisions from occurring during the docking process.

[0078] After docking, the two cars work together through their respective roller conveyor transmission mechanism, lifting mechanism and lifting arm to smoothly transfer the molten iron ladle 3 from the multi-functional furnace front car 2 to the multi-functional tilting car 1, thus completing the handover of the molten iron ladle.

[0079] After the handover is completed, the multi-functional tilting vehicle 1 automatically travels along track 6 to the corresponding filling station of the casting machine 4. Through its own rotating and lifting mechanisms, it adjusts the height and angle of the molten iron ladle 3. Then, the tilting mechanism slowly tilts the ladle 3, precisely filling the molten iron into the casting machine 4 to meet the casting production requirements. The entire filling process is unattended, and the filling amount can be precisely controlled based on weighing data, avoiding molten iron waste and casting deviations.

[0080] When the casting operation is completed and there is residual molten iron in the casting machine 4 that needs to be returned to the furnace, the multi-functional tilting car 1 travels to the bottom of the casting machine 4, grabs the empty molten iron ladle 3 with the lifting arm, adjusts its posture, and then receives the residual molten iron discharged from the casting machine 4.

[0081] After the receiving is completed, the multi-functional tilting car 1 travels along the track 6 to the docking position with the multi-functional furnace front car 2. The two cars work together to transfer the ladle 3 containing the remaining molten iron to the multi-functional furnace front car 2.

[0082] Subsequently, the multi-functional furnace front car 2 travels along the track 6 to the return station of the electric furnace 5, and uses its own tilting mechanism to tilt the molten iron ladle 3, accurately pouring the remaining molten iron back into the electric furnace 5, thus completing the molten iron return process.

[0083] After the remelting is completed, the two cars will transfer the empty molten iron ladle 3 to the designated storage location to await the next round of operation, thus realizing the cyclical operation of the entire system.

[0084] Throughout the entire workflow, the movement, lateral movement, rotation, lifting, grabbing, and molten iron ladle tilting of the multi-functional tilting car 1 and the multi-functional furnace front car 2 are all completed through an automated control system, eliminating the need for manual on-site operation.
