[0003] In the existing molten iron transfer technology, a crane is usually used to correspond to one molten iron ladle, and a sequential operation mode is used between multiple stations. This mode mainly depends on the lifting operation of the crane and the cooperation of the ground transportation equipment. After the crane lifts the molten iron ladle, it is moved to the designated position, and then the molten iron ladle is lowered. The ground transportation equipment is used to transport the molten iron ladle from one station to another station. However, in the sequential operation process of using one crane to correspond to one molten iron ladle, when the molten iron is discharged from the converter or the electric furnace, the empty molten iron ladle needs to be positioned, and after the molten iron is discharged, the full molten iron ladle needs to be transferred to the casting station, and the converter needs to wait for the next empty molten iron ladle, which leads to high idle rate of equipment and reduces the efficiency of molten iron transfer.

[0030] The technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of the present invention, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of the present invention without creative effort are also within the protection scope of the present invention.

[0031] This application mainly adopts steel ladle cars, paths, and lifting components to achieve molten iron transfer in a coordinated manner, which reduces equipment idle rate, improves molten iron transfer efficiency, and ensures stable operation of the production line. The following is a further detailed description of this application.

[0032] The automatic molten iron transfer device provided in the embodiments of this application, such as Figures 1 to 5 As shown, the system includes a ladle car, an outbound path, a return path, a buffer station 203, and a first lifting assembly. The ladle car moves along both the outbound and return paths. The buffer station 203 is located on the return path and contains empty molten iron ladles. The first lifting assembly is used to place the empty molten iron ladles into the ladle car. This eliminates the need to wait for empty molten iron ladles to be transferred from other distant locations to the furnace station 201. After the ladle car returns, it can quickly load empty molten iron ladles to perform the transfer task again, reducing equipment idle time and improving molten iron transfer efficiency. Furthermore, it reduces manual intervention, lowers safety risks during molten iron transfer, and ensures the stable operation of the production line. This is because the ladle car can operate cyclically according to a preset path, and the buffer station 203 is set up with empty molten iron ladles prepared in advance. The first lifting assembly can load them onto the ladle car in a timely manner, avoiding waiting time and the uncertainty of manual operation.

[0033] Specifically, such as Figure 1 and Figure 4As shown, the first lifting assembly includes a first support 301, a first drive unit 302, and a first hook 303. The first support 301 is typically welded from high-strength steel and has a frame structure, providing stable support for the entire first lifting assembly. In some special environments, a concrete support structure can be used to enhance its stability and corrosion resistance. The first support 301 is fixed to the ground 700° using anchor bolts or similar methods to ensure it does not sway during lifting operations. The first drive unit 302 can be a winch, which is connected to the first hook 303 via a wire rope. The winch is characterized by its powerful performance and precise control, accurately driving the first hook 303 to change height. Alternatively, a hydraulic drive unit can be used instead of a winch, offering advantages such as smooth operation and high load-bearing capacity. The first hook 303 is generally manufactured using a forging process, and its material is high-strength alloy steel, possessing good toughness and wear resistance. The first hook 303 is manually removed and hooked. The first hook 303 is connected to the wire rope via a connecting ring. The other end of the wire rope is wound inside the winch. The connecting ring is secured with high-strength bolts to ensure reliable connection. The first drive unit 302 is mounted on the first support 301. When the first drive unit 302 is activated, the first hook 303 is raised or lowered by the winding and unwinding of the wire rope, thereby enabling the hoisting and placement of the empty molten iron ladle.

[0034] In this embodiment, as Figure 1 and Figure 4 As shown, the first lifting assembly also includes a first track 304 and a first moving part 305. The first track 304 is typically made of I-beams or channel steel, and its surface is precision-machined to reduce frictional resistance between the first moving part 305 and the track. The first track 304 is fixed to the first bracket 301 by welding or bolting, and at least a portion of the track section is located directly above the buffer station 203. The first moving part 305 can be an electric trolley, which is connected to the first track 304 via rollers and can move along the first track 304. The electric trolley is equipped with a drive motor and a control system, and the forward and backward movement of the trolley is achieved by controlling the forward and reverse rotation of the motor. Alternatively, the first moving part 305 can be driven by a chain drive, which has the advantages of high transmission efficiency and large load-bearing capacity. The first driving component 302 is installed on the first moving component 305. When the first moving component 305 moves along the first track 304, it can drive the first driving component 302 and the first hook 303 to adjust their positions, so that the first hook 303 can move to the corresponding position of the empty molten iron ladle on the buffer station 203 for hooking.

[0035] like Figure 1 and Figure 2As shown, this embodiment also includes a second track 401. The extension path of the second track 401 coincides with both the outbound and return paths. The ladle car is located on the second track 401 and moves along it. The second track 401 is laid with heavy-duty steel rails, which have high strength and wear resistance. The track is fixed to the ground 700 by sleepers and track spikes to ensure track stability. The ladle car is located on the second track 401 and contacts the track through its wheels 102. The second track 401 provides guidance for the movement of the ladle car, preventing it from deviating during movement and ensuring that the ladle car can move stably along the set outbound and return paths. At the same time, the track-based movement method reduces the frictional resistance during the movement of the ladle car, reduces equipment wear, extends equipment service life, and improves the movement efficiency of the ladle car, further ensuring the overall efficiency of molten iron transfer.

[0036] like Figure 2 As shown, in this embodiment, the ladle car includes a body 101, wheels 102, a second drive unit, a support saddle, and a protective plate 103. The body 101 is typically welded from steel plates, with an internal frame structure to enhance its strength and rigidity. The wheels 102 are rotatably connected to the body 101 via bearings. The wheels 102 are made of high-strength alloy steel, possessing good wear resistance and load-bearing capacity. The second drive unit can be an electric motor, mounted on the body 101 and connected to the wheels 102 via a transmission device. Electric motors are characterized by rapid start-up and convenient speed adjustment, enabling the wheels 102 to rotate and achieving automated movement of the ladle car. Alternatively, an internal combustion engine can be used as the second drive unit, offering advantages such as strong power and long range. The support saddle is fixedly installed on the top of the body 101, its shape adapted to the bottom of the molten iron ladle, used for inserting the ladle, and provides stable positioning for the ladle, preventing it from shaking or tipping over during transport. The guard plate 103 is fixed to the car body 101 by welding or bolting, and the guard plate 103 is provided with a guide groove. The guard plate 103 is generally made of high temperature resistant and high strength alloy material. When molten iron splashes out, the guide groove can guide the molten iron to a specific area to prevent the molten iron from flowing randomly and causing equipment damage or safety accidents.

[0037] like Figure 1 , Figure 3 and Figure 5As shown, this embodiment also includes a second lifting assembly, which includes a second support 501, a third rail 502, a second moving part 503, a third driving part 504, and a second hook 505. The second support 501 is made of high-strength steel or concrete to provide stable support for the second lifting assembly. The third rail 502 is installed on the second support 501 and extends from the first lifting station 202 to the casting station 204. The third rail 502 is made of I-beams or channel steel. The second moving part 503 can be an electric trolley, which is connected to the third rail 502 and can move along the third rail 502. The electric trolley is driven by a motor. The third driving part 504 can be a winch or a hydraulic drive device, which is installed on the second moving part 503 and connected to the second hook 505 via a wire rope. The second hook 505 has a similar structure and material to the first hook 303 and is used to hook the molten iron ladle. The third drive component 504 can drive the second hook 505 to change its height, realizing the hoisting and placement of the molten iron ladle. The second lifting assembly can hook the molten iron ladle loaded with molten iron at the first lifting station 202, and then move it to the casting station 204 along the third track 502 via the second moving component 503. This realizes the automated transfer of the molten iron ladle from the first lifting station 202 to the casting station 204 without the need for additional transfer equipment, simplifying the transfer process. At the same time, the third drive component 504 drives the second hook 505 to rise and fall, which can complete the hooking and placement of the molten iron ladle, improving the accuracy and efficiency of the transfer of the molten iron ladle between the two stations, further improving the automation process of molten iron transfer, and improving the rhythm of the entire production line.

[0038] like Figure 1 , Figure 3 and Figure 5As shown, the second lifting assembly also includes a fourth rail 506 and a third moving member 507. The fourth rail 506 is fixedly connected to the second support 501, and at least a portion of the fourth rail 506 is located above the second lifting position 205. The structure and material of the fourth rail 506 are similar to those of the first rail 304. The third moving member 507 is connected to the fourth rail 506 and can move along the fourth rail 506. The third moving member 507 can be an electric trolley or a chain drive device, and a third rail 502 is fixedly connected to it. When the third moving member 507 moves along the fourth rail 506, it can adjust the position of the third rail 502, so that the second lifting assembly can cover the second lifting position 205. By combining the first track 304 section located at the second lifting station 205, the lifting of empty molten iron ladles by the second lifting component can be replaced by the lifting by the first lifting component, while the second lifting component returns to the first lifting station 202. This enables the first and second lifting components to work collaboratively at the second lifting station 205. It allows for flexible transfer and scheduling of molten iron ladles between different stations, expands the operating range of the second lifting component, improves the operational flexibility and adaptability of the entire transfer device, better meets the diverse transfer needs of the production line, and further improves transfer efficiency.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the molten iron ladle has a body 601, a first trunnion 602, a second trunnion 603, and a support frame 604. The body 601 is generally cast from heat-resistant steel and has an open receiving cavity for holding molten iron. The first trunnion 602 and the second trunnion 603 are fixed to the outer wall of the body 601 and are arranged symmetrically to each other. The trunnions are made of solid forged steel, and their two ends are rigidly connected to the external reinforcing frame of the body 601 by high-strength bolts to ensure the load-bearing strength during hoisting and tipping. The support frame 604 is connected to the first trunnion 602 and the second trunnion 603 respectively. The support frame 604 can be a steel frame structure for hooking to the first hook 303 or the second hook 505. Because the main body 601 has two symmetrically arranged force-bearing points, the molten iron ladle can maintain balance during hoisting, avoiding tilting during hooking and causing molten iron to overflow; the support frame 604 is connected to two trunnions, which further improves the structural stability of the molten iron ladle, enhances the load-bearing capacity of the molten iron ladle during transportation, reduces the risk of damage and leakage of the molten iron ladle due to structural instability, and ensures the safety of molten iron transportation.

[0040] like Figure 2As shown, in this embodiment, the molten iron ladle also includes a fourth driving component 605, which is mounted on the first support frame 604 and connected to the second trunnion 603. The fourth driving component 605 can be a hydraulically driven device, comprising a driven gear mounted on one end of the trunnion, a driving gear meshing with the driven gear, and a hydraulic motor connected to the driving gear via a universal coupling. By remotely controlling the forward and reverse rotation of the hydraulic motor, the molten iron ladle can be driven to rotate precisely around the trunnion, achieving quantitative iron addition or pouring. An electric driving device can also be used instead of a hydraulically driven device, offering advantages such as precise control and fast response. The fourth driving component 605 can drive the ladle body 601 to rotate, achieving automated pouring of molten iron without manual operation, reducing labor intensity and operational risks. Simultaneously, the rotation method driven by the driving component allows control of the rotation angle and speed, enabling adjustment of the molten iron pouring amount and speed according to the needs of subsequent processes, improving the accuracy and stability of molten iron pouring, ensuring product quality in subsequent processes, and further enhancing the automation and operational efficiency of the entire production line.

[0041] The implementation principle of this embodiment is as follows: This automatic molten iron transfer device in front of the furnace achieves efficient and safe transfer of molten iron through the coordinated operation of its various components. The ladle car operates cyclically according to the preset outbound and return paths. The buffer station 203 prepares empty molten iron ladles in advance, and the first lifting component loads them onto the ladle car, avoiding waiting time and the uncertainty of manual operation. The first and second lifting components, through the cooperation of tracks and moving parts, expand the working range and improve the flexibility and efficiency of lifting operations. The structural design of the molten iron ladle ensures its stability and safety during hoisting and transfer. The fourth drive component 605 realizes the automated pouring of molten iron, improving the accuracy and stability of molten iron pouring. The entire device reduces equipment idle time, reduces manual intervention, lowers safety risks, and ensures the stable operation of the production line, representing a significant improvement and enhancement compared to existing technologies.
