A transverse sliding plate slag baffle and flow control device for converters

Abstract

This invention discloses a transverse sliding plate slag-blocking and flow control device for converters, comprising a connecting plate, a baffle, a first channel, and a second channel. A sliding tube is slidably fitted within the first channel. A monitoring device is mounted on the baffle, and a rubber block is mounted on top of the monitoring device. When using this slag-blocking and flow control device, the sliding tube is raised when slag accumulates, increasing the space capacity of the first channel. As slag continues to accumulate, it compresses the rubber block. At this point, a pressure sensor detects the pressure, and the controller sends a prompt to a mobile terminal, timely reminding the operator to activate the slag-blocking and flow control device to discharge the slag from the converter. The rubber block can block the slag, either deflecting it or drawing it into the block, preventing the slag from impacting the pressure sensor when it hits the baffle. This, to a certain extent, prevents slag backflow from affecting the converter.

Description

Technical Field

[0001] This invention belongs to the field of converters, specifically a transverse sliding plate slag-blocking and flow-controlling device for converters. Background Technology

[0002] With the rapid development of the steel industry, users' requirements for steel quality are increasing. Therefore, producing high-quality, high-tech, and high-value-added steel products has become an inevitable choice for steel enterprises. The quality of molten steel directly affects the performance of the steel products. Reducing the amount of slag added during the converter tapping process is a crucial step in improving steel quality. How to reduce the amount of slag added during converter tapping has long been a technical challenge for the steel industry and has become a limiting factor in the production of special and high-quality steel in converters. Through visits and exchanges, it was found that steel mills that do not use converter sliding plate slag blocking generally use slag-blocking balls or plugs. However, these methods cannot block the initial slag, so many steel mills hope to use converter slag-blocking technology. However, because many converters are quite old, early converters did not have space reserved for the use of modern converter slag-blocking technology, resulting in unsuitable tapping port structures and the inability to properly use the slag-blocking mechanism.

[0003] To address the aforementioned issues, Chinese Patent Publication No. CN 211620557 U discloses a transverse sliding plate slag-blocking and flow-controlling device for converters, belonging to the field of metallurgical steelmaking. This device utilizes a reference plate, connecting plate, fixed base plate, clamping frame, and moving frame, horizontally positioned at the converter taphole, effectively avoiding the drawbacks of the early inability to properly utilize the sliding plate slag-blocking device in converters. A driving component completely offsets the moving frame and its internal moving sliding plate from the fixed sliding plate within the fixed base plate, achieving the slag-blocking function. The clamping frame, using clamping components, presses the moving frame vertically. Two sets of sliding strips are provided between the moving frame and the clamping frame, respectively parallel and perpendicular to the moving sliding plate. This eliminates contact between the clamping frame and the moving frame under gravity during installation and operation, preventing wear and tear. It also effectively prevents misalignment between the moving and fixed sliding plates and eliminates the possibility of premature failure, comprehensively ensuring the device's service life and improving its performance.

[0004] This solution can achieve the function of slag blocking and flow control. However, when the slag in the converter is not turned on by the personnel, the slag will accumulate on the slag blocking and flow control device. After the slag accumulates on the slag blocking and flow control device, it is easy to cause slag backflow, which will cause the slag to mix with the materials in the converter and even damage the internal structure of the converter. Therefore, it is necessary to install a transverse sliding plate slag blocking and flow control device for converter. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a transverse sliding plate slag-blocking and flow-controlling device for converters, in order to prevent slag backflow from affecting the converter.

[0006] 1. To achieve the above objectives, the technical solution of the present invention is as follows: A transverse sliding plate slag-blocking and flow control device for converters includes a connecting plate and a baffle plate. A monitoring device and a power device are installed on the baffle plate. The bottom of the connecting plate is provided with an I-shaped first slider. The top of the baffle plate is provided with a first sliding groove that slides with the first slider. The connecting plate and the baffle plate are respectively provided with a first channel and a second channel. A sliding tube is slidably fitted in the first channel. A magnetic paper is provided between the sliding tube and the connecting plate. The two sides of the magnetic paper are fixedly connected to the sliding tube and the connecting plate respectively. The bottom of the sliding tube is provided with a second sliding groove. A second slider is slidably fitted in the second sliding groove. The bottom of the second slider is fixedly connected to the connecting plate. A flow guide plate is fixedly connected to the connecting plate. The flow guide plate is provided with a plurality of flow guide holes. The monitoring device includes a pressure sensor. The pressure sensor is embedded in the upper part of the baffle plate. The top of the pressure sensor is provided with a rubber block with a central protrusion. The pressure sensor signal is connected to a controller. The controller signal is connected to a mobile terminal.

[0007] The connecting plate is equipped with a warning component, which includes a movable rod. One end of the movable rod is fixedly connected to the sliding tube. The connecting plate is equipped with a movable groove. The movable rod is located in the movable groove and slides in cooperation with the movable groove. The movable rod extends to the outside of the connecting plate. A flag is fixedly connected to one end of the movable rod located outside the connecting plate.

[0008] The principle and beneficial effects of the above scheme are as follows: When using the slag-blocking and flow-controlling device, the device is horizontally fixed at the slag outlet of the converter. When the slag-blocking and flow-controlling device is not used, it is in the open state, with the first and second channels staggered, and the bottom of the first channel abutting against the baffle. When slag is discharged from the slag outlet, steel slag enters the first channel. At this time, the steel slag impacts the guide plate, which guides the steel slag to the bottom of the sliding tube. When the steel slag slides below the sliding tube, it lifts the sliding tube, thus increasing the space of the first channel, which can accommodate more steel slag, giving workers more time to notice that steel slag discharge has begun.

[0009] As steel slag accumulates, it compresses the rubber block, causing it to deform and indent. This indentation comes into contact with a pressure sensor, which transmits the pressure information to the controller. Based on this information, the controller processes it and sends a notification to a mobile terminal, promptly reminding staff to activate the slag-blocking and flow-control device to discharge the steel slag from the converter. This, to a certain extent, prevents steel slag backflow from affecting the converter.

[0010] The rubber block can block the steel slag, either bouncing it away or sucking it into the rubber block, thus preventing the steel slag from affecting the pressure sensor when it impacts the baffle.

[0011] When workers discover that steel slag has been discharged, they activate the flow control and slag-blocking device. Workers use a controller to operate the power equipment, which pulls the connecting plate, causing the first slider to slide within the first groove. When the first channel on the connecting plate aligns with the second channel on the baffle plate, the steel slag can be discharged through the second channel. As the connecting plate moves, it crushes the rubber block, forcing the steel slag into its interior. When the connecting plate returns to its original position, the rubber block regains its original shape, and its surface remains flat, preventing further steel slag buildup. As steel slag accumulates within the rubber block, it gradually penetrates to the bottom. When the block reaches saturation, the slag will penetrate the rubber block, continuously contacting the pressure sensor. The pressure sensor receives information about the continuous pressure and transmits this information to the controller. The controller processes this information and sends a notification to a mobile terminal, reminding workers to replace the rubber block promptly.

[0012] Furthermore, the power equipment includes a fixed block, which is fixedly connected to one side of the baffle. A hydraulic cylinder is fixedly connected to the upper part of the fixed block. The hydraulic cylinder is signal-connected to the controller, and the output shaft of the hydraulic cylinder is fixedly connected to the connecting plate.

[0013] Beneficial effect: The power equipment makes it easy to turn the slag-blocking and flow-controlling device on and off.

[0014] Furthermore, a support plate is fixedly connected to the bottom of the fixing block, and the side of the support plate away from the fixing block is fixedly connected to the baffle.

[0015] Beneficial effects: The support plate facilitates the support of the fixed block, making the fixed block more stable.

[0016] Furthermore, a warning light and a buzzer are installed on the fixed block, both of which are connected to the controller signal.

[0017] Beneficial effects: When the pressure sensor reaches the threshold or is continuously subjected to pressure, the pressure sensor transmits the obtained pressure information to the controller. Based on this information, the controller processes it and then activates the warning light and buzzer alarm to alert surrounding workers and remind them to activate the flow control and slag-blocking device in a timely manner.

[0018] Furthermore, a handle is fixedly connected to the fixing block.

[0019] Beneficial effect: The handle allows staff to easily operate the flow control and slag-blocking device manually.

[0020] Furthermore, the handle has an anti-slip texture.

[0021] Beneficial effects: The anti-slip texture increases the contact area between the hand and the handle, increasing the friction between them and thus achieving an anti-slip effect. Attached Figure Description

[0025] The following detailed description illustrates the specific implementation method:

[0026] The reference numerals in the accompanying drawings include: connecting plate 1, baffle 2, first slider 3, first slide groove 4, first channel 21, second channel 5, magnetic paper 6, sliding tube 7, second slide groove 8, second slider 9, guide plate 10, rubber block 11, moving rod 12, moving groove 13, flag 14, fixing block 15, hydraulic cylinder 16, support plate 17, warning light 18, buzzer alarm 19, and pressure sensor 22.

[0027] The basic implementation examples are as follows: Figure 1 Appendix Figure 2 and attached Figure 3 As shown:

[0028] A transverse sliding plate slag-blocking and flow control device for converters includes a connecting plate 1 and a baffle 2. The bottom of the connecting plate 1 has an integrally formed I-shaped first slider 3. The top of the baffle 2 has a first groove 4 that slides with the first slider 3. The connecting plate 1 and the baffle 2 have a first channel 21 and a second channel 5 respectively in their middle sections. A sliding tube 7 slides within the first channel 21. A magnetic paper 6 is provided between the sliding tube 7 and the connecting plate 1. The magnetic paper 6 is fixedly connected to the sliding tube 7 and the connecting plate 1 on its upper and lower sides respectively. A second groove 8 is formed at the bottom of the sliding tube 7. A second slider 9 slides within the second groove 8. The bottom of the second slider 9 is fixedly connected to the connecting plate 1. A flow guide plate 10 is fixedly connected to the connecting plate 1, and the flow guide plate 10 has several flow guide holes. A monitoring device is installed on the baffle 2, including a pressure sensor 22 embedded in the upper part of the baffle 2. The pressure sensor 22 has a centrally protruding rubber block 11 on its top. The pressure sensor 22 is signal-connected to a controller, and the controller is signal-connected to a mobile terminal.

[0029] A warning component is installed on the connecting plate 1. The warning component includes a movable rod 12. One end of the movable rod 12 is fixedly connected to the sliding tube 7. A movable groove 13 is opened on the connecting plate 1. The movable rod 12 is located in the movable groove 13 and slides in cooperation with the movable groove 13. The movable rod 12 extends to the outside of the connecting plate 1. A flag 14 is fixedly connected to one end of the movable rod 12 located outside the connecting plate 1.

[0030] A power unit is installed on the baffle 2. The power unit includes a fixing block 15, which is fixedly connected to one side of the baffle 2. A hydraulic cylinder 16 is fixedly connected to the top of the fixing block 15, and the hydraulic cylinder 16 is connected to the controller via signal. The output shaft of the hydraulic cylinder 16 is fixedly connected to the connecting plate 1. A support plate 17 is fixedly connected to the bottom of the fixing block 15, and the side of the support plate 17 away from the fixing block 15 is fixedly connected to the baffle 2. A warning light 18 and a buzzer alarm 19 are installed on the fixing block 15, and both the warning light 18 and the buzzer alarm 19 are connected to the controller via signal. A handle with anti-slip texture is fixedly connected to the fixing block 15.

[0031] The specific implementation process is as follows: The device is horizontally fixed at the slag outlet of the converter. The connecting plate 1 is fixed to the slag outlet, and the sliding tube is located inside the slag outlet. When the flow control and slag blocking device is not in use, it is in the closed state. At this time, the first channel 21 and the second channel 5 are staggered, and the bottom of the first channel 21 abuts against the baffle 2. When slag is discharged from the slag outlet, the steel slag enters the first channel 21. At this time, the steel slag impacts the guide plate 10, which guides the steel slag to the bottom of the sliding tube 7. When the steel slag slides under the sliding tube 7, it lifts the sliding tube 7. At this time, the space of the first channel 21 increases, which can accommodate more steel slag, giving the staff more time to notice that the steel slag has begun to be discharged and to promptly activate the flow control and slag blocking device.

[0032] When the steel slag enters the bottom of the sliding tube 7, the magnetic paper 6 continuously absorbs the slag. Because the sliding tube 7 still exerts pressure on the connecting plate 1, it can squeeze and compress the slag, further increasing the slag capacity of the first channel 21. Furthermore, when the sliding tube 7 returns to its original position, it squeezes the magnetic paper 6, causing it to wrinkle. The sliding tube 7 continues to squeeze the magnetic paper 6, expelling the steel slag and allowing it to be reused. When the sliding tube 7 rises, the moving rod 12 slides within the moving groove 13, and the flag 14 on the moving groove 13 moves simultaneously. At this time, the operator can judge the amount of steel slag in the first channel 21 based on the change in the height of the flag 14.

[0033] As steel slag continues to accumulate, it compresses the rubber block 11. Under this pressure, the rubber block 11 deforms and indents downwards. Upon contact with the pressure sensor 22, the pressure sensor 22 senses the pressure and transmits the pressure information to the controller. Based on this pressure information, the controller processes it and sends a notification to the mobile terminal, promptly reminding staff to activate the slag-blocking and flow-control device to discharge the steel slag from the converter. This, to a certain extent, prevents the backflow of steel slag from affecting the converter.

[0034] The rubber block 11 can block the steel slag, bounce the steel slag away or suck the steel slag into the rubber block 11, thus preventing the steel slag from affecting the pressure sensor 22 when it impacts the baffle 2.

[0035] When the staff discovers that the steel slag has been discharged, they activate the flow control and slag-blocking device. The staff can pull or push the baffle 2, or use the controller to operate the power equipment. The support plate 17 provides support for the fixed block 15, making the fixed block 15 more stable. At this time, the hydraulic cylinder 16 operates, and the output shaft of the hydraulic cylinder 16 pulls the connecting plate 1, causing the first slider 3 to slide in the first slide groove 4. When the first channel 21 on the connecting plate 1 coincides with the second channel 5 on the baffle 2, the steel slag can be discharged from the second channel 5. When the connecting plate 1 moves, the connecting plate 1 crushes the rubber block 11. At this time, the steel slag on the rubber block 11 is pressed into the interior of the rubber block 11. When the connecting plate 1 returns to its original position, the rubber block 11 also returns to its original shape, and the surface of the rubber block 11 remains flat, which can block the next steel slag.

[0036] As steel slag continues to accumulate inside the rubber block 11, it gradually extends into the bottom of the block. When the amount of steel slag inside the block reaches saturation, it will penetrate the block. At this point, the block continues to contact the pressure sensor 22, which receives information about the continuous pressure. The pressure sensor 22 transmits this information to the controller. Based on this information, the controller processes it and sends a notification to the mobile terminal, reminding staff to replace the rubber block 11 in a timely manner.

[0037] When the pressure sensor 22 reaches the threshold or is continuously subjected to pressure, it transmits the pressure information to the controller. The controller processes this information and activates the warning light 18 and buzzer alarm 19 to alert nearby workers and remind them to activate the flow control and slag-blocking device. This prevents slag from continuously accumulating and flowing back into the converter, thus avoiding any impact on the converter.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention.
