Description

Technical Field

[0001] This invention relates to the field of heating furnace temperature distribution technology, specifically to a step-type heating furnace temperature distribution adjustment device. Background Technology

[0002] A walking beam furnace is an industrial furnace primarily used for heating metal billets, commonly found in rolling production lines in the steel and non-ferrous metals industries. The key features of a walking beam furnace are its ability to achieve continuous heating, improving production efficiency, and ensuring uniform heating of the metal billet during the heating process, which contributes to improved product quality. Walking beam furnaces are mainly classified into conventional, gas-fired, oil-fired, vacuum, and electromagnetic induction types.

[0003] However, in the operation of existing walking beam furnaces, operators typically set the furnace parameters and start heating. This approach has limitations in controlling the temperature of the billet within the furnace. For example, because the billet remains stationary during heating, it cannot be heated evenly, and the furnace temperature cannot be fully controlled or adjusted. This results in uneven heating or areas not being heated properly. If the billet cannot be heated evenly or the temperature cannot be controlled, uneven heating can lead to deformation, cracks, and uneven sintering, increasing the defect rate. Furthermore, if the oxide layer formed on the billet surface due to uneven heating or furnace temperature is not addressed promptly, it reduces heat transfer, resulting in poor and uneven heating, ultimately affecting product quality and performance. Furthermore, if no treatment is performed during the heating process of the billet in the furnace, the billet may collide with the inner wall of the furnace during the conveying process. If the inner wall of the furnace is not maintained in time under such circumstances, it will directly affect the service life of the furnace. If it is not replaced in time and continues to be used, it will lead to the risk of the furnace cracking or exploding during the heating process.

[0004] Therefore, in view of this, the present invention proposes a temperature distribution adjustment device for a walking beam furnace to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a device that can automatically rotate and heat billets evenly during heating, can automatically vibrate to remove oxide scale from the surface of billets during conveying, can automatically bring the conveyed billets closer to the center during vibration, and can prevent damage to the furnace inner wall due to collisions with billets, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a walking beam furnace temperature distribution adjustment device, comprising a furnace bottom, a reciprocating guide rod for transmission rotatably connected inside the furnace bottom, a fixing block for supporting the reciprocating guide rod fixedly connected inside the furnace bottom, and a conveying platform for conveying heated billets movably connected inside the furnace bottom; the walking beam furnace temperature distribution adjustment device includes: a heating uniformity mechanism and a vibration slag removal mechanism, the heating uniformity mechanism being disposed on the fixing block, and the vibration slag removal mechanism being disposed on one side of the inner wall of the furnace bottom. The uniform heating mechanism is used to uniformly heat the billet in the heating furnace; The vibration slag removal mechanism is used to remove oxides from the uniformly heated billet by vibration.

[0007] Preferably, the uniform heating mechanism includes a slider 1 slidably connected to a reciprocating guide rod, an auxiliary rotating column rotatably connected to the top of the slider 1, a toothed block 1 fixedly connected to the top of the auxiliary rotating column, an auxiliary magnet embedded in the surface of the toothed block 1, a rotating platform fixedly connected to the surface of the toothed block 1 by magnetic attraction of the auxiliary magnet, and a toothed block 2 fixedly connected to the bottom of the slider 1.

[0008] Preferably, the uniform heating mechanism includes a gear rotatably connected to the inner wall of the furnace bottom, a toothed block three is rotatably connected to the inner wall of the furnace bottom, and a transmission belt one is driven to the outer ring surface of the reciprocating guide rod near the gear end.

[0009] Preferably, the vibration slag removal mechanism includes a toothed column 1 rotatably connected to the inner wall of the furnace bottom, a transmission belt 1 with its end away from the reciprocating guide rod being connected to the toothed column 1, a toothed column 2 rotatably connected inside the furnace bottom, the teeth on the toothed column 1 meshing with the teeth on the toothed column 2, a fixed curved block fixedly connected to the top of the toothed column 2, a fixed block 2 fixedly connected to the bottom surface of the conveying platform, a rotating column 1 rotatably connected to the fixed block 2, the rotating column 1 being slidably connected to the fixed curved block, and a transmission belt 2 being connected to the outer ring of the toothed column 1.

[0010] Preferably, the vibration slag removal mechanism includes a rotating column two that is rotatably connected to the inside of the furnace bottom, a transmission belt two that is remote from the toothed column one that is connected to the rotating column two, a cam that is fixedly connected to the rotating column two, a fixed block three that is fixedly connected to the bottom of the conveying platform, a slider two that is slidably connected to the fixed block three, a return spring that is fixedly connected inside the fixed block three, a return spring that is remote from the fixed block three that is fixedly connected to the slider two, and a slider three that is fixedly connected to the side of the slider two that is remote from the fixed block three.

[0011] Compared with the prior art, the present invention provides a temperature distribution adjustment device for a walking beam furnace, which has the following advantages: (1) By setting a uniform heating mechanism, the billet can be rotated and heated uniformly when the heating furnace heats the billet. By controlling the rotation speed, uniform heating can be maintained during the billet heating process, thereby reducing the temperature difference during heating, thus improving the stability of the billet or heated product quality, and also avoiding the billet or product from uneven sintering, deformation and cracking caused by uneven heating. (2) The vibration slag removal mechanism can be set to vibrate the billet after it is uniformly heated. It can effectively break the oxide scale on the surface of the billet due to uneven heating during heating by vibrating left and right. It can remove the oxides generated after heating the billet. The billet after removing the oxides can reduce the defects and unevenness on the surface of the billet in the heating furnace, which can improve the quality and appearance of the billet or product. It can also make the billet heat more evenly in the heating furnace, improve the heat transfer and absorption efficiency, and thus improve the heating effect. 3. The vibration slag removal mechanism can flip the billets near the outside of the conveying platform by a slider while vibrating, which can make the billets on the conveying platform heat better and more evenly in the heating furnace. It can also bring some cylindrical or spherical billets that are easy to roll due to vibration closer to the center of the heating furnace, thereby reducing the risk of the billets colliding with the inner wall of the heating furnace during vibration, effectively slowing down the wear of the inner wall of the heating furnace, and extending the service life of the heating furnace.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Embodiments of the present invention Please refer to Figures 1 to 7 As shown: To address the problems mentioned in the technical solutions, this application provides a walking beam furnace temperature distribution adjustment device, including a furnace bottom 1, a reciprocating guide rod 2 rotatably connected inside the furnace bottom 1 for transmission, a fixing block 3 fixedly connected inside the furnace bottom 1 for supporting the reciprocating guide rod 2, and a conveying platform 4 movably connected inside the furnace bottom 1 for conveying heated billets. The walking beam furnace temperature distribution adjustment device includes a heating uniformity mechanism 5 and a vibration slag removal mechanism 6. The heating uniformity mechanism 5 is mounted on the fixing block 3, and the vibration slag removal mechanism 6 is located on one side of the inner wall of the furnace bottom 1. The uniform heating mechanism 5 is used to uniformly heat the billet in the heating furnace; The vibration slag removal mechanism 6 is used to remove oxides from the uniformly heated billet by vibration.

[0016] The uniform heating mechanism 5 includes a slider 501 slidably connected to the reciprocating guide rod 2, an auxiliary rotating column rotatably connected to the top of the slider 501, a toothed block 502 fixedly connected to the top of the auxiliary rotating column, an auxiliary magnet embedded in the surface of the toothed block 502, a rotating platform 503 fixedly connected to the surface of the toothed block 502 by magnetic attraction through the auxiliary magnet, and a toothed block 504 fixedly connected to the bottom of the slider 501.

[0017] The uniform heating mechanism 5 includes a gear 505 that is rotatably connected to the inner wall of the furnace bottom 1, a toothed block 506 that is rotatably connected to the inner wall of the furnace bottom 1, and a transmission belt 507 that is driven to the outer ring surface of the reciprocating guide rod 2 near the end of the gear 505.

[0018] Among them: the teeth on the second tooth block 504 are the same size as the teeth on the gear 505; the width of the clamping block on the third tooth block 506 is greater than that of the first tooth block 502; the surface of the clamping block on the third tooth block 506 and the bottom of the rotating platform 503 are equipped with magnets that can attract each other; the surface of the clamping block on the third tooth block 506 can contact the bottom of the rotating platform 503.

[0019] The vibrating slag removal mechanism 6 includes a toothed column 601 rotatably connected to the inner wall of the furnace bottom 1, a transmission belt 507 at one end away from the reciprocating guide rod 2 being connected to the toothed column 601, a toothed column 602 rotatably connected inside the furnace bottom 1, the teeth on the toothed column 601 meshing with the teeth on the toothed column 602, a fixed curved block 603 fixedly connected to the top of the toothed column 602, a fixed block 605 fixedly connected to the bottom surface of the conveying platform 4, a rotating column 604 rotatably connected to the fixed block 605, the rotating column 604 being slidably connected to the fixed curved block 603, and a transmission belt 606 drivingly connected to the outer ring of the toothed column 601.

[0020] The vibration slag removal mechanism 6 includes a rotating column 607 rotatably connected to the inside of the furnace bottom 1, a transmission belt 606 with one end away from the toothed column 601 being connected to the rotating column 607, a cam 608 fixedly connected to the rotating column 607, a fixed block 609 fixedly connected to the bottom of the conveying platform 4, a slider 6010 slidably connected to the fixed block 609, a return spring 6011 fixedly connected inside the fixed block 609, one end of the return spring 6011 away from the fixed block 609 being fixedly connected to the slider 6010, and a slider 6012 fixedly connected to the side of the slider 6010 away from the fixed block 609.

[0021] Wherein: the width of cam 608 is the same as the width of slider 6012, and the contact between cam 608 and slider 6012 is not affected during the vibration of conveying platform 4.

[0022] The working principle of all the content in the above embodiments is as follows: In the initial state: the rotating platform 503 is sleeved with the toothed block 502, the clamping block on the toothed block 506 is parallel to the fixed block 3, and the billet to be heated is placed on the rotating platform 503.

[0023] The following describes the working process of the heating uniformity mechanism 5 rotating the heated billet during heating to achieve uniform heating: While the furnace begins heating the billet inside, the reciprocating guide rod 2 also begins to rotate, causing the slider 501 to slide forward on the fixed block 3. Since the teeth at the bottom of the toothed block 502 connected to the slider 501 mesh with the teeth at the top of the rotating platform 503, the toothed block 502 can rotate on the slider 501 through the teeth at the top of the fixed block 3 while sliding. Furthermore, it can drive the billet on the top of the rotating platform 503 to rotate as well. This allows the billet to rotate and adjust its position while being heated in the furnace, maintaining the uniformity of heating. The speed control of the reciprocating guide rod 2 during rotation ensures that the billet is heated better and more evenly in the furnace, effectively reducing the occurrence of scrap and defective products due to uneven heating, such as uneven sintering, deformation, and cracks. Furthermore, during the heating process, when the slider 1 501 drives the rotating platform 503 to slide to the other end of the fixed block 1 3, the teeth on the surface of the toothed block 2 504 can mesh with the teeth of the gear 505, and the clamping block on the toothed block 3 506 is located below the rotating platform 503 on the same horizontal plane. As a result, the toothed block 2 504 begins to mesh and rotate with the gear 505 due to the sliding of the slider 1 501. The toothed block 3 506, through the meshing and rotation of the gear 505, can drive the clamping block to lift up and flip. Since the clamping block on the toothed block 3 506 and the rotating platform 503 can be magnetically attracted due to physical properties, the toothed block 2 504 can mesh and rotate with the gear 505 at the same time, and the toothed block 3 506 can drive the rotating platform 503 to flip. Furthermore, by driving the rotating platform 503 to flip through the toothed block 3 506, the billet that has been uniformly heated on the rotating platform 503 can be placed on the conveying platform 4, which can be automatically transported during the heating process in the furnace, thereby speeding up the working efficiency of the heating furnace. Please refer to the above work process. Figures 1 to 4 .

[0024] The following describes the process by which the vibrating slag removal mechanism 6 vibrates the uniformly heated billet placed on the conveying platform 4 while the reciprocating guide rod 2 rotates, thereby removing oxides from the surface of the billet: Furthermore, while the reciprocating guide rod 2 rotates, the toothed column 601 rotates through the transmission belt 507, and the teeth on the toothed column 601 mesh with the teeth on the toothed column 602. This causes the toothed column 601 to rotate while driving the toothed column 602 to rotate. Since the rotating column 604 can slide on the fixed block 603, and the rotating column 604 is rotatably connected to the fixed block 605, and the rotating column 604 is restricted by the fixed block 603, the toothed column 602 can drive the rotating column 604 to rotate while rotating. Furthermore, when the toothed column 601 rotates in conjunction with the rotating column 604, the rotating column 604, restricted by the fixed block 603, can drive the conveying platform 4 to vibrate left and right. This vibrates the uniformly heated billet on the conveying platform 4 to remove the oxides after heating, breaks the oxide scale on the surface of the billet during heating, effectively promotes heat transfer, and improves the uniformity of temperature distribution. Furthermore, while the gear column 601 rotates, the rotating column 607 rotates via the transmission belt 606. A fixed block 609 is fixedly connected to the conveyor platform 4, and a slider 6010 is slidably connected to the fixed block 609. The side of the slider 6010 away from the fixed block 609 is fixedly connected to the slider 6012, allowing the slider 6010 to slide and drive the slider 6012 to slide. Since the slider 6012 can slide on the conveyor platform 4, a return spring 6011 is fixedly connected inside the fixed block 609. A cam 608 is fixedly connected to the rotating column 607, and the cam 608 contacts the bottom of the slider 6012. Furthermore, due to the physical shape of the cam 608, the rotating column 607 can lift the slider 6012 upwards as it rotates, and the slider 6012 remains on the conveyor platform. 4. As the cam 608 slides downward following the rotating column 607, the physical properties of the return spring 6011 inside the fixed block 609 will press the slider 6010 downward to reset it. Furthermore, as the rotating column 607 rotates, it can drive the slider 6012 to slide up and down on the conveying platform 4, thereby turning over the vibrating billet on the conveying platform 4. This allows the oxide scale on the surface of the billet to fall off after vibration. The turned billet can also be heated better, which can improve the uniformity of billet heating. The slider 6012 can also bring some cylindrical or spherical billets that are easy to roll due to vibration to the center, which can reduce the risk of the billet colliding with the inner wall of the furnace bottom 1 when the conveying platform 4 vibrates. This reduces the wear of the heating furnace and extends its service life. Please refer to the above work process. Figures 1 to 7 .

[0025] Summary: The uniform heating mechanism 5 ensures that the billet rotates at a constant speed during heating in the furnace, guaranteeing even heating and preventing uneven sintering, deformation, cracking, and other defects caused by uneven heating. The vibration slag removal mechanism 6 vibrates the billet placed on the conveyor platform 4 from side to side as the reciprocating guide rod 2 rotates. This vibration removes oxides from the billet after heating, breaking up uneven surfaces caused by heating. The oxide scale caused by heating can effectively promote heat transfer and improve the uniformity of temperature distribution on the billet. Through the lifting and sliding device slider 3 6012, the billet near slider 3 6012 can be flipped while the billet on the conveying platform 4 is vibrated. This can make the billet heat better and more evenly in the heating furnace. It can also bring some cylindrical or spherical billets that are easy to roll due to vibration closer to the center, which can reduce the damage caused by the collision between the billet and the inner wall of the furnace bottom 1 during vibration, effectively slow down the wear of the inner wall of the heating furnace, and extend the service life of the heating furnace.
