Description

Technical Field

[0001] This utility model relates to the field of steel ladle casting technology, and in particular to a steel ladle casting displacement cylinder device. Background Technology

[0002] In the iron and steel metallurgical production process, ladle pouring is a crucial step in continuous casting or ingot casting. Its core task is to stably and controllably inject molten steel from the ladle into the tundish or mold. The stability of the pouring speed directly affects the solidification quality of the molten steel, the uniformity of the internal structure of the cast billet, and production safety. Therefore, precisely controlling the nozzle opening during the pouring process, and thus regulating the molten steel flow rate, has become an important technical means to ensure product quality and production efficiency.

[0003] Currently, the adjustment of the ladle nozzle opening still relies primarily on manual operation. Operators manually adjust the opening and closing degree of the sliding nozzle based on experience, and the control of the pouring speed can only rely on visual inspection and estimation. Due to the lack of quantitative basis and real-time feedback mechanism, this operation method makes it difficult to achieve precise control. The pouring speed is greatly affected by human factors, resulting in poor consistency between different batches. This can easily lead to problems such as steel flow fluctuations, slag entrapment, and increased inclusions, seriously affecting the stability of molten steel pouring and the quality of the final product.

[0004] Therefore, a ladle casting displacement cylinder device is needed. Utility Model Content

[0006] This utility model provides the following technical solution: a steel ladle casting displacement cylinder device, comprising a displacement cylinder, a linkage mechanism, a sprue mechanism, a fixing plate, a cylinder body, a displacement sensor, a control cabinet, a wireless transmitter, and a wireless receiver. The displacement cylinder is mounted on the fixing plate, and the linkage mechanism is mounted on the right side of the displacement cylinder.

The displacement cylinder is connected to the linkage mechanism through a joint on the cylinder body. The linkage mechanism is tightly connected to the sliding plate of the sprue mechanism. The lower sprue is fixed on the sliding plate of the sprue mechanism. The displacement of the cylinder body is exactly equal to the displacement of the lower sprue. A displacement sensor is mounted on the left side of the displacement cylinder, and the sensing element of the displacement sensor is inserted into the cylinder body.

Detailed Implementation

[0023] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0024] Example 1: A hydraulic cylinder device for ladle casting displacement, please refer to [link / reference]. Figures 1-5The system includes a displacement cylinder 1, a linkage mechanism 2, a sprue mechanism 3, a fixing plate 4, a cylinder body 5, a displacement sensor 6, a control cabinet 7, a wireless transmitter 8, and a wireless receiver 9. The displacement cylinder 1 is mounted on the fixing plate 4. The linkage mechanism 2 is mounted on the right side of the displacement cylinder 1. The sprue mechanism 3 consists of an upper sprue and a lower sprue. The cylinder body 5 is mounted on the linkage mechanism 2. The displacement cylinder 1 is connected to the linkage mechanism 2 via a connector on the cylinder body 5. The linkage mechanism is tightly connected to the sliding plate of the sprue mechanism 3. The lower sprue is fixed on the sliding plate of the sprue mechanism 3. The displacement of the cylinder body 5 is exactly equal to the displacement of the lower sprue. The displacement sensor 6 is mounted on the left side of the displacement cylinder 1. The sensing element of the displacement sensor 6 is inserted into the cylinder body. Inside the cylinder body 5, a control cabinet 7 is installed at the front of the fixed plate 4. A wireless transmitter 8 is installed on the top of the control cabinet 7, and a wireless receiver 9 is installed on the left side of the fixed plate 4. It also includes a first connecting plate 10, a second connecting plate 11, and a corrugated cover 12. The first connecting plate 10 is installed on the right side of the displacement cylinder 1, and the second connecting plate 11 is installed on the left side of the linkage mechanism 2. A corrugated cover 12 is provided between the first connecting plate 10 and the second connecting plate 11. A buffer pad 19 is bonded to the bottom of the fixed plate 4. The buffer pad 19 can absorb the vibration and impact during equipment operation and improve the stability of system operation. A protective shell 20 is rotatably installed at the front of the fixed plate 4. The protective shell 20 shields the control cabinet 7 to prevent external collisions or high temperatures from damaging electrical components.

[0025] When the device is in use, during operation, the hydraulic system drives the piston rod of the displacement cylinder 1 to extend and retract, which in turn drives the linkage mechanism 2. One end of the linkage mechanism 2 is linked to the displacement cylinder 1, and the other end is rigidly connected to the sliding plate of the sprue mechanism 3. The sprue is fixedly mounted on the sliding plate. Therefore, the movement of the linkage mechanism 2 will directly drive the sprue to move horizontally, thereby adjusting the opening between the sprue and the upper sprue. Since the displacement of the cylinder body 5 is equal to the actual displacement of the sprue, the system has good linear response characteristics, ensuring control accuracy. The displacement sensor 6 detects the displacement of the piston rod in real time and feeds the signal back to the control cabinet 7. The control cabinet 7 processes and analyzes the signal and adjusts the hydraulic system output according to preset parameters, thereby precisely controlling the stroke of the displacement cylinder 1 and ensuring the accuracy and stability of the sprue position. After processing the displacement signal, the control cabinet 7 transmits the data to its... The top-mounted wireless transmitter 8 sends signals to a remote wireless receiver 9, enabling wireless data transmission. After receiving the signal, the wireless receiver 9 can monitor and display the displacement in real time, allowing operators to remotely monitor the pouring status. Through the combination of hydraulic drive, mechanical transmission, and wireless communication technology, quantitative control of the nozzle opening during ladle pouring is achieved, thereby precisely regulating the pouring speed. This effectively solves the problem of relying on experience to judge the opening size and pouring speed in traditional manual operation, realizing visualized and precise control of the pouring process, improving the stability of molten steel pouring and product quality. In addition, the corrugated cover 12 is set between the first connecting plate 10 and the second connecting plate 11 to seal and protect the connection parts of the linkage mechanism 2 and the cylinder body 5, preventing slag splashing and dust intrusion, and ensuring the cleanliness and normal operation of the transmission components.

[0026] Example 2: Based on Example 1, please refer to... Figure 4 It also includes an isolation plate 13, screws 14 and a heat insulation plate 15. The isolation plate 13 is installed on the displacement cylinder 1 by screws 14, and the heat insulation plate 15 is provided on the surface of the isolation plate 13.

[0027] The isolation plate 13 is installed on the displacement cylinder 1 by screws 14, and its surface is covered with a heat insulation plate 15 to block the high temperature radiation of the ladle, protect the displacement cylinder 1, and extend its service life.

[0028] Please see Figure 5 It also includes a storage frame 16 and a rotating plate 17. The storage frame 16 is installed at the rear of the fixed plate 4. The rotating plate 17 is rotatably installed on the top of the storage frame 16. A pull rod 18 is fixedly connected to the rear side of the rotating plate 17. The pull rod 18 increases the force point between the hand and the rotating plate 17, making it easier to rotate the rotating plate 17.

[0029] Before using the device, the rotating plate 17 can be rotated upward to open the opening of the storage box 16, and the required tools can be placed in the box for storage, making it convenient to retrieve them later. After the tools are stored, the rotating plate 17 can be rotated downward to reset it and cover the opening of the storage box 16, thus achieving closure and protection.
