Description

Technical Field

[0001] This utility model belongs to the field of metallurgical technology, and specifically relates to a steel wire wheel for cleaning iron oxide in a walking beam furnace. Background Technology

[0002] A walking beam furnace is a continuous heating furnace that uses the rising, advancing, descending, and retracting motion of the furnace bottom or water-cooled metal beams to move the billet forward step by step. It is a type of continuous heating furnace that uses a dedicated walking mechanism to move along a specific trajectory (usually a rectangular trajectory) to advance the steel material inside the furnace step by step, hence the name walking beam furnace. The wire wheel is used to clean the iron oxide from the discharge rollers of the walking beam furnace.

[0003] However, the traditional steel wire wheel used for cleaning iron oxide in walking beam furnaces has a limited cleaning range and cannot cover the iron oxide scale at the discharge end roller, which easily leads to the accumulation of iron oxide scale in this area. The operation is laborious, making it difficult to guarantee the cleaning effect and affecting the overall work efficiency due to the time spent on debugging and operation. At the same time, it requires manual operation by the operator, which leads to high physical exertion and fatigue during long-term operation. It is also difficult to maintain a stable position while manually holding the wheel, which is prone to shaking and affects the cleaning accuracy. Incomplete cleaning or omissions are often caused by positional deviation, which not only reduces the safety of operation, but also affects the overall work efficiency.

[0004] To address the problems mentioned in the background above, a steel wire wheel for cleaning iron oxide in a walking beam furnace is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a steel wire wheel for cleaning iron oxide in a walking beam furnace, which has the advantages of being easy to clean and labor-saving to fix.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a wire wheel for cleaning iron oxide in a walking beam furnace, comprising a housing, a sliding sleeve embedded in the top of the housing, a sliding rod slidably sleeved inside the sliding sleeve, a threaded sleeve fixedly sleeved on the back of the sliding rod, a screw threadedly connected inside the threaded sleeve, a connecting block rotatably connected to the bottom of the screw, a bracket bolted to the bottom of the connecting block, a rotating shaft rotatably sleeved through the front and back of the bracket, a wire wheel fixedly sleeved in the middle of the surface of the rotating shaft, and positioning mechanisms provided on both sides of the inner wall of the housing.

[0007] The above technical solution allows the sliding rod to slide within the sliding sleeve after the mechanism is fixed, thereby adjusting the front and rear positions of the threaded sleeve and wire wheel on the back of the sliding rod. Rotating the screw inside the threaded sleeve causes the connecting block at the bottom and the bracket bolted below the connecting block to move up and down, thereby adjusting the height of the wire wheel fixed to the rotating shaft on the bracket. The wire wheel contacts the iron oxide to be cleaned in the walking beam furnace, starting the rotation of the discharge roller at the furnace without heating it. This allows the wire wheel to rub against the rotating drum and clean it. The rotating shaft can rotate with the cleaning action, enabling the wire wheel to clean the iron oxide. This solution can adapt to the iron oxide cleaning needs at different heights and front and rear positions in the walking beam furnace, ensuring that the cleaning operation can cover the iron oxide scale on the discharge roller of the walking beam furnace. It has strong operational stability and can flexibly adjust the position of the wire wheel according to the thickness and distribution of the iron oxide on site, eliminating the need for complex debugging procedures and saving effort in operation.

[0008] The present invention is further configured such that the positioning mechanism includes a spring, the spring is bolted to both sides of the inner wall of the outer shell, a clamping block is bolted to the end of the spring away from the outer shell, and a telescopic rod is sleeved inside the spring.

[0009] The above technical solution employs a positioning mechanism. When cleaning the discharge rollers of the heating furnace is required, outward force is applied to open the clamping blocks on both sides. The springs are compressed and undergo elastic deformation. Simultaneously, the telescopic rod extends and retracts axially to ensure the stability of the clamping block's movement direction. After the external force is removed, the springs return to their original shape and drive the clamping blocks to move inward, making the clamping blocks tightly fit against the connection of the discharge rollers of the heating furnace. At the same time, the telescopic rod restricts the lateral displacement of the springs, ultimately achieving stable positioning of the device. After positioning, the discharge rollers of the heating furnace can be cleaned. The device can be clamped and fixed at the connection of the discharge rollers of the walking beam heating furnace without manual gripping, effectively reducing the physical burden on operators and avoiding fatigue caused by prolonged hand operation. In the fixed state, the device maintains stable position, reducing possible shaking during manual gripping, ensuring the cleaning accuracy of iron oxide scale at the discharge rollers, avoiding the impact of positional displacement on the cleaning effect, improving operational safety, and ensuring overall work efficiency.

[0010] The present invention is further configured such that connecting plates are bolted to both sides of the connecting block, sliders are welded to both sides of the threaded sleeve, and a sliding groove is provided on the top of the inner side of the connecting plate, and the interior of the sliding groove is slidably connected to the surface of the slider.

[0011] The above technical solution, by setting a connecting plate, a slider, and a slide groove, can limit the movement of the connecting block.

[0012] The present invention is further configured such that the front and rear ends of the rotating shaft surface away from the middle are threaded with limit nuts.

[0013] The above technical solution involves setting a limit nut to limit the rotation shaft and prevent it from falling off.

[0014] The present invention is further configured such that protective pads are adhered to the opposite sides of the two clamping blocks.

[0015] The above technical solution, by setting up a protective pad, can prevent the clamping block from damaging the surface of the roller connection at the discharge end of the heating furnace.

[0016] The present invention is further configured such that a knob is fixedly sleeved on the top of the screw.

[0017] The above technical solution allows for easy rotation of the screw by incorporating a knob.

[0018] The present invention is further configured such that a handle is fixedly sleeved on the front of the slide rod.

[0019] The above technical solution allows for easy pushing and pulling of the slide bar by incorporating a handle.

[0020] The present invention is further configured such that a pull block is bolted to the front of the clamping block.

[0021] The above technical solution involves setting up a pull block, which allows the clamping block to be easily pulled open.

[0022] In summary, this utility model has the following beneficial effects: 1. This utility model can adapt to the iron oxide cleaning needs of different heights and front and rear positions in the walking beam furnace, ensuring that the cleaning operation can cover the iron oxide scale on the discharge end roller of the walking beam furnace. It has strong operational stability and can flexibly adjust the position of the wire wheel according to the thickness and distribution of iron oxide on site. No complicated debugging process is required, and the operation is labor-saving. 2. This utility model can be clamped and fixed at the connection of the discharge roller of the walking beam furnace, eliminating the need for manual gripping. This effectively reduces the physical burden on operators, avoids fatigue caused by prolonged hand operation, and maintains a stable position in the fixed state, reducing the shaking that may occur when manually gripping. This ensures the cleaning accuracy of iron oxide scale at the discharge roller, avoids affecting the cleaning effect due to positional deviation, improves operational safety, and guarantees overall work efficiency.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1: refer to Figure 1 , Figure 2 , Figure 3 A steel wire wheel for cleaning iron oxide in a walking beam furnace includes a housing 1. A sliding sleeve 2 is embedded in the top of the housing 1. A sliding rod 3 is slidably sleeved inside the sliding sleeve 2. A threaded sleeve 4 is fixedly sleeved on the back of the sliding rod 3. A screw rod 5 is threadedly connected inside the threaded sleeve 4. A connecting block 6 is rotatably connected to the bottom of the screw rod 5. A bracket 8 is bolted to the bottom of the connecting block 6. A rotating shaft 9 is rotatably sleeved through the front and back of the bracket 8. A steel wire wheel 10 is fixedly sleeved in the middle of the surface of the rotating shaft 9. The steel wire wheel 10 is made of 65Mn. Positioning mechanisms are provided on both sides of the inner wall of the housing 1. After the mechanisms are fixed, the sliding rod 3 can... The sliding sleeve 2 slides, thereby driving the screw sleeve 4 and the wire wheel 10 on the back of the sliding rod 3 to adjust their front and rear positions. The screw 5 inside the screw sleeve 4 is rotated, which drives the connecting block 6 at the bottom and the bracket 8 bolted below the connecting block 6 to move up and down. This adjusts the height of the wire wheel 10 fixed on the rotating shaft 9 on the bracket 8. The wire wheel 10 contacts the iron oxide to be cleaned in the walking beam furnace. The discharge end roller of the furnace is started to rotate, but it is not heated. This allows the wire wheel 10 to rub against the rotating drum and clean it. The rotating shaft 9 can rotate with the cleaning action, so that the wire wheel 10 can clean the iron oxide.

[0027] refer to Figure 1 , Figure 2 , Figure 3 Connecting plates 7 are bolted to both sides of the connecting block 6, and sliders 14 are welded to both sides of the screw sleeve 4. A groove 15 is provided on the top of the inner side of the connecting plate 7, and the inside of the groove 15 is slidably connected to the surface of the slider 14. By setting the connecting plate 7, slider 14 and groove 15, the movement of the connecting block 6 can be limited.

[0028] refer to Figure 3 The front and rear ends of the rotating shaft 9, which are far from the middle, are threaded with limit nuts 16. By setting the limit nuts 16, the rotating shaft 9 can be limited to prevent it from falling off.

[0029] refer to Figure 1 , Figure 2 , Figure 3A knob 18 is fixedly sleeved on the top of the screw 5, which allows the screw 5 to be rotated easily.

[0030] refer to Figure 1 A handle 19 is fixedly sleeved on the front of the slide bar 3, which makes it easy to push and pull the slide bar 3.

[0031] Example 2: refer to Figure 1 A steel wire wheel for cleaning iron oxide in a walking beam furnace includes a positioning mechanism comprising a spring 11. The spring 11 is bolted to both sides of the inner wall of the outer shell 1. The spring 11 is made of 50CrVA high-temperature resistant spring steel with a stiffness coefficient of 15-25 N / mm. A clamping block 12 is bolted to the end of the spring 11 away from the outer shell 1. A telescopic rod 13 is sleeved inside the spring 11. When it is necessary to clean the discharge end roller of the furnace, an outward force is applied to open the clamping blocks 12 on both sides. The spring 11 is compressed and undergoes elastic deformation. The telescopic rod 13 simultaneously extends and retracts axially to ensure the stability of the movement direction of the clamping block 12. After the external force is removed, the spring 11 returns to its original shape and drives the clamping block 12 to move inward, so that the clamping block 12 fits tightly against the connection of the discharge end roller of the furnace. At the same time, the telescopic rod 13 restricts the lateral displacement of the spring 11, and finally achieves stable positioning of the device. After positioning, the discharge end roller of the furnace is cleaned.

[0032] refer to Figure 1 The two clamping blocks 12 have protective pads 17 glued to their opposite sides. By setting the protective pads 17, the clamping blocks 12 can prevent them from damaging the surface of the roller connection at the discharge end of the heating furnace. The material is silicone rubber.

[0033] refer to Figure 1 A pull block 20 is bolted to the front of the clamping block 12. By setting the pull block 20, the clamping block 12 can be easily pulled open.

[0034] Brief description of usage: After the mechanism is fixed, the slide bar 3 can slide within the slide sleeve 2, thereby driving the screw sleeve 4 and wire wheel 10 on the back of the slide bar 3 to adjust their front and rear positions. Rotating the screw 5 inside the screw sleeve 4 will cause the connecting block 6 at the bottom and the bracket 8 bolted below the connecting block 6 to move up and down, thereby adjusting the height of the wire wheel 10 fixed to the rotating shaft 9 on the bracket 8. The wire wheel 10 contacts the iron oxide to be cleaned in the walking beam furnace, and the discharge roller of the furnace is started to rotate, but not heated, so that the wire wheel 10 can rub against the rotating drum and clean it. The rotating shaft 9 can move with the roller. The cleaning action rotates, causing the wire wheel 10 to clean the iron oxide. When it is necessary to clean the discharge end roller of the heating furnace, the clamping blocks 12 on both sides are opened by applying outward force. The spring 11 is compressed and undergoes elastic deformation. The telescopic rod 13 extends and retracts axially at the same time to ensure the stability of the movement direction of the clamping block 12. After the external force is removed, the spring 11 returns to its original state and drives the clamping block 12 to move inward, so that the clamping block 12 fits tightly against the connection of the discharge end roller of the heating furnace. At the same time, the telescopic rod 13 restricts the lateral displacement of the spring 11, and finally achieves the stable positioning of the device. After positioning, the discharge end roller of the heating furnace is cleaned.
