Description

Technical Field

[0001] This invention belongs to the technical field of billet processing equipment, and relates to a billet raw material heating device, particularly a billet raw material heating device for steel bar processing. Background Technology

[0002] Steel billets refer to steel raw materials that have undergone preliminary processing but have not yet been further refined. They are typically produced from iron ore through processes such as smelting, steelmaking, and continuous casting. Steel billets are commonly used to produce various types and specifications of steel products, such as steel plates, steel pipes, and steel bars. In further processing, steel billets undergo processes such as rolling, forging, and die casting to obtain the desired final products.

[0003] A search revealed a Chinese patent document that discloses a billet heating and conveying device [Application No.: 202411132433.2; Publication No.: CN 118996091 B]. A billet heating and conveying device, relating to the field of billet heating and conveying technology, includes a cross plate. A motor is located at the bottom of the cross plate, and a transmission rod is fixedly connected to the motor's power output shaft. Multiple billets are sequentially placed into adjacent vertical cylinders. The motor drives the cross plate to rotate, and the cross plate, centered on the transmission rod, drives a rotating rod and a limiting cylinder to rotate. During rotation, the limiting cylinder contacts a convex plate, which pushes the limiting cylinder upwards and then downwards, thereby helping to shake the inclined billets inside the vertical cylinders, causing them to displace and enter corresponding holes. The cross plate drives the rotating rod to rotate, and a gear contacts a gear ring, which in turn drives the rotating rod to rotate. The rotating rod then drives the limiting cylinder to rotate, causing the limiting cylinder to rotate on its own axis. After heating the billets, the movable cylinder is removed from the vertical cylinder, and the vertical cylinder is placed horizontally at a connecting plate. The vertical cylinder is moved and conveyed by the inclination of the connecting plate.

[0004] Although this patent involves removing the movable cylinder from the vertical cylinder after the billet is heated and placing the vertical cylinder horizontally at the connecting plate, with the vertical cylinder moving and conveying itself based on the inclination of the connecting plate, it is still necessary to remove the iron oxide scale generated on the surface of the heated billet to prevent iron oxide scale from being pressed into the rolls during the rolling process, causing defects such as uneven marks, peeling, and cracks on the finished product surface. Removing the iron oxide scale can improve the internal structure and properties of the billet, increase its plasticity and ductility, reduce its hardness and brittleness, and reduce cracking and fracture during the rolling process. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a steel billet heating device for steel bar processing. The technical problem to be solved by this invention is: how to use the high-pressure, high-temperature gas generated during heating to clean the iron oxide scale on the surface of the steel billet.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A steel billet heating device for rebar processing includes a heating frame and a heating channel within the heating frame. A pair of stabilizing frames are fixed to the heating frame at both ends of the heating channel. Each stabilizing frame has a ring-shaped track frame fixed to it, and each ring-shaped track frame has a conveying frame. Each conveying frame has a pair of stabilizing arms fixed to it, with one end of each stabilizing arm slidably connected to the corresponding ring-shaped track frame. A pair of clamping frames are slidably disposed within each conveying frame, and each clamping frame has a conveying wheel rotatably connected to it. A servo motor is fixed within each clamping frame, and the output shaft of each servo motor is coaxially fixedly connected to the corresponding conveying wheel. Each stabilizing arm contains a drive assembly for controlling the clamping action of the clamping frames. An induction heating coil is fixed to the top of the heating channel, and a pressure relief channel communicating with the heating channel is provided on the heating frame for pressure relief. An electromagnetic pressure relief valve is fixed inside the channel, and a drive impeller is rotatably connected inside the pressure relief channel. A lower pressure frame is slidably connected inside the heating frame, and a cleaning roller is rotatably connected inside the lower pressure frame. Multiple cleaning steel strips are fixed on the surface of the cleaning roller, and a transmission bevel gear is coaxially fixedly connected to the drive impeller. A transmission bevel gear is rotatably connected inside the heating frame, and the transmission bevel gear is meshed with the transmission bevel gear. A transmission bevel gear is coaxially fixedly connected to the transmission bevel gear. A transmission bevel gear is rotatably connected inside the heating frame, and the transmission bevel gear is meshed with the transmission bevel gear. A cross transmission rod is coaxially fixedly connected to the transmission bevel gear. A transmission worm is rotatably connected inside the lower pressure frame, and a cross transmission hole is opened on the transmission worm. The cross transmission rod and the cross transmission hole are inserted into each other. A transmission worm wheel is coaxially fixedly connected to the cleaning roller, and the transmission worm wheel meshes with the transmission worm.

[0008] The working principle of this invention is as follows: A steel billet is clamped and fixed using a clamping frame. During the fixing process, a servo motor drives a conveyor wheel to rotate, which transports the steel billet into the heating frame. Inside the heating frame, an induction heating coil heats the steel billet. Although the induction heating coil does not directly heat the air during the heating process, the high temperature on the surface of the steel billet causes the surrounding air to expand and increase in volume. The air inside the heating frame expands in volume, decreases in density, and becomes lighter, causing the hot air to rise and accumulate at the top of the heating channel. At this point, a pressure relief channel guides and transports this high-pressure, high-temperature gas. During transport, the high-pressure, high-temperature gas blows a drive impeller, which in turn drives a transmission bevel gear. The rotation of the drive impeller then drives a transmission bevel gear, which in turn drives a transmission bevel gear, which in turn drives a transmission bevel gear. The transmission bevel gear continues to rotate, and so on. The moving bevel gear five drives the transmission bevel gear six to rotate, which in turn drives the cross transmission rod to rotate. The cross transmission rod then drives the transmission worm gear to rotate through its insertion into the cross transmission hole. The transmission worm gear drives the cleaning roller to rotate, and the rotation direction of the cleaning roller is opposite to the direction of the billet conveying. This allows the cleaning steel bar to cooperate with the billet conveying action to roll and rub the surface of the billet. The energy stored in the high-pressure gas (e.g., 30MPa) can be released through the throttle valve to drive equipment such as the pneumatic ejector. Its energy density is far greater than that of lithium batteries (up to 120kJ / L). Therefore, by accumulating pressure and releasing the high-pressure gas appropriately, the above-mentioned rolling action can be achieved, cleaning the iron oxide layer generated after the billet is heated, improving the effect of subsequent rolling. Furthermore, the degree of pressure release is controlled by the electromagnetic pressure relief valve, thereby further controlling the speed of the drive impeller by adjusting the degree of pressure release, and further controlling the washing efficiency.

[0009] The drive assembly includes a control screw rotatably connected to both stabilizer arms and a servo motor II fixedly connected to both stabilizer arms. The output shaft of each servo motor II is coaxially fixedly connected to a corresponding control screw, and each control screw is threadedly connected to a corresponding clamping frame.

[0010] With the above structure, the control screw can be rotated by the second servo motor. After the control screw rotates, it will push the corresponding clamping frame to move, thereby further realizing the relative or opposite movement of the two clamping frames, completing the clamping effect of the steel billet, and facilitating the normal operation of subsequent conveying work.

[0011] The annular track frame is provided with an annular guide groove. Each of the two stabilizing arms is rotatably connected to a follower wheel. The wheel surface of each follower wheel is in contact with the annular guide groove. Each of the two stabilizing arms is rotatably connected to a drive wheel. Each of the two stabilizing arms is fixed with a servo motor. The output shaft of each servo motor is coaxially fixedly connected to the corresponding drive wheel. The wheel surface of each drive wheel is in contact with the surface of the annular track frame.

[0012] With the above structure, the drive wheel can be rotated by the servo motor. The drive wheel, in turn, rotates the two stabilizing arms, the conveying frame and other structures by contacting the surface of the ring track frame. This allows the entire billet to rotate at an angle during the clamping process, improving the uniformity of heating.

[0013] A pair of opposing bonding frames are fixed on the conveying frame. Each bonding frame has a bonding groove, and a wheel seat is slidably connected in each bonding groove. A bonding wheel is rotatably connected on each wheel seat, and a bonding spring is fixed between each wheel seat and the bottom of the corresponding bonding groove.

[0014] With the above structure, the sliding wheel seat can be adjusted according to the thickness of the steel billet, and the wheel seat is pushed by the contact spring so that the wheel surface of the contact wheel is always in contact with the surface of the steel billet.

[0015] The heating frame is slidably connected to a second lower pressure frame, and both the first and second lower pressure frames are fixed with connecting rods. The top of each connecting rod extends out of the heating frame and is fixed with a counterweight. The top surface of the second lower pressure frame is rotatably connected to a guide roller, and the roller surface of the guide roller contacts the surface of the steel billet. The second lower pressure frame is equipped with a striking component, and the guide roller is connected to the striking component.

[0016] Using the above structure, the counterweight can apply pressure to the lower pressure frame one and the lower pressure frame two, so that the lower pressure frame one and the lower pressure frame two can always be in contact with the surface of the billet. When the billet is being transported, the billet can drive the guide roller to rotate. After the guide roller rotates, it will drive the striking component to strike the billet, causing the billet to vibrate. When the billet vibrates rapidly, the impurities on the billet surface tend to maintain their original motion state (stationary or low-speed movement) due to inertia. The high-frequency oscillation of the billet surface causes the impurities to be relatively displaced from the billet surface, and finally detach from the billet surface, further improving the cleaning effect of the iron oxide layer on the billet.

[0017] The striking assembly includes a sliding groove inside the lower pressure frame 2, a striking block slidably connected inside the sliding groove, and a first transmission gear and a second transmission gear rotatably connected inside the lower pressure frame 2. A sector gear is coaxially fixedly connected to the second transmission gear, the first transmission gear is coaxially fixedly connected to the guide roller, a rack is fixed to one side of the striking block, the rack meshes with the sector gear, a first transmission belt is connected to the first transmission gear and the second transmission gear, and a push spring is fixed between the bottom of the sliding groove and the striking block.

[0018] Using the above structure, the guide roller drives the first transmission gear to rotate. After the first transmission gear rotates, it drives the second transmission gear to rotate through the first transmission belt. After the second transmission gear rotates, it drives the sector gear to rotate. After the sector gear rotates, the teeth of the sector gear mesh with the rack. The sector gear then drives the striking block to rise. When the missing tooth part of the sector gear contacts the rack, the striking block loses its restraint, the push spring releases the pressure, and pushes the striking block down, thus realizing the striking work. Furthermore, through the continuous rotation of the sector gear, the striking block can achieve continuous striking.

[0019] The cleaning roller is hollow inside and has a vibrating rod rotatably connected inside. Multiple support rods are arranged and fixed on the vibrating rods. A push spring is fixed to one end of each support rod. A vibrating block is fixed to each push spring. Multiple resonant steel blocks are arranged and fixed on the inner wall of the cleaning roller. Each vibrating block is engaged with a corresponding resonant steel block through a striking action. Each resonant steel block is fixedly connected to a corresponding cleaning steel strip.

[0020] With the above structure, the vibrating rod rotates inside the cleaning roller. After the vibrating rod rotates, it will drive each support rod to rotate as a whole, and further drive each vibrating block to rotate. During the overall rotation, each vibrating block will continuously strike the corresponding resonant steel block, causing the resonant steel block to vibrate. This vibration force is guided to the cleaning steel bar, so that when the cleaning steel bar comes into contact with the iron oxide scale on the steel billet, it can apply vibration force to it, thereby improving the cleaning effect.

[0021] The bottom surface of the lower pressure frame is rotatably connected to a follower roller. The roller surface of the follower roller is in contact with the surface of the steel billet, and a transmission gear three is coaxially fixedly connected to the follower roller. A transmission gear four is coaxially fixed to the vibrating rod, and a transmission toothed belt two is connected to the transmission gear three and the transmission gear four.

[0022] With the above structure, during the billet conveying process, the billet drives the follower roller to rotate, and the rotation of the follower roller will drive the transmission gear three to rotate. After the transmission gear three rotates, it will drive the transmission gear four to rotate through the transmission belt two, and the transmission gear four will drive the vibrating rod to rotate.

[0023] The bottom of the heating channel is rotatably connected to multiple conveying rollers, and a waste collection chamber located at the bottom of the heating channel is opened inside the heating frame, with the opening of the waste collection chamber connected to the heating channel.

[0024] With the above structure, the cleaned iron oxide scale can be collected through the waste collection chamber.

[0025] The heating rack has a placement opening that connects to the waste collection chamber. A collection box is slidably inserted into the placement opening, and an operating handle is fixed on the collection box.

[0026] With the above structure, iron oxide scale can be collected in the collection box through the waste collection chamber, making it convenient for personnel to handle it uniformly later.

[0027] Compared with existing technologies, this steel billet heating equipment for steel bar processing has the following advantages:

[0028] 1. High-pressure, high-temperature gas is guided and transported through a pressure relief channel. During the transport process, the high-pressure, high-temperature gas blows the drive impeller. The rotation of the drive impeller drives the first transmission bevel gear to rotate, which in turn drives the second transmission bevel gear to rotate. The second transmission bevel gear then drives the cross transmission rod to rotate. The cross transmission rod, through its insertion into the cross transmission hole, drives the transmission worm gear to rotate. The transmission worm gear drives the cleaning roller to rotate, and the rotation direction of the cleaning roller is opposite to the direction of the billet conveying. This allows the cleaning steel bar to cooperate with the billet conveying action to roll and rub the surface of the billet, cleaning the iron oxide layer generated after the billet is heated.

[0029] 2. The servo motor drives the drive wheel to rotate. The drive wheel, in turn, rotates the two stabilizing arms, the conveying frame, and other structures by contacting the surface of the ring track frame. This allows the entire billet to rotate at an angle during the clamping process, improving the uniformity of heating.

[0030] 3. By applying pressure to the lower pressure frame one and lower pressure frame two through the counterweight, the lower pressure frame one and lower pressure frame two can always be in contact with the surface of the steel billet. When the steel billet is conveyed, the steel billet can drive the guide roller to rotate. After the guide roller rotates, it will drive the striking component to strike the steel billet, causing the steel billet to vibrate. When the steel billet vibrates rapidly, the impurities on the surface of the steel billet tend to maintain their original motion state (stationary or low-speed movement) due to inertia. The high-frequency oscillation of the steel billet surface causes the impurities to be relatively displaced from the surface of the steel billet, and finally detaches from the surface of the steel billet, further improving the cleaning effect of the iron oxide layer of the steel billet.

[0031] 4. The vibrating rod rotates inside the cleaning roller. After the vibrating rod rotates, it will drive each support rod to rotate as a whole, and further drive each vibrating block to rotate. During the overall rotation, each vibrating block will continuously strike the corresponding resonant steel block, causing the resonant steel block to vibrate. This vibration force is guided to the cleaning steel bar, so that when the cleaning steel bar comes into contact with the iron oxide scale on the steel billet, it can apply vibration force to it, thereby improving the cleaning effect.

[0041] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0042] like Figures 1-8As shown, a steel billet heating device for rebar processing includes a heating frame 1 and a heating channel 2 opened within the heating frame 1. A pair of stabilizing frames 3 are fixed on the heating frame 1 at both ends of the heating channel 2. Annular track frames 4 are fixed on each of the two stabilizing frames 3, and a conveying frame 5 is provided on each annular track frame 4. A pair of stabilizing arms 6 are fixed on each conveying frame 5, with one end of each stabilizing arm 6 slidably connected to the corresponding annular track frame 4. A pair of clamping frames 7 are slidably arranged within each conveying frame 5, and a conveying wheel 8 is rotatably connected to each clamping frame 7. A servo motor 9 is fixed within each clamping frame 7, and the output shaft of each servo motor 9 is coaxially fixedly connected to the corresponding conveying wheel 8. A drive assembly for controlling the clamping action of the clamping frame 7 is provided within each stabilizing arm 6. An induction heating coil 10 is fixed to the top of the heating channel 2, and a pressure relief channel 11 communicating with the heating channel 2 is opened on the heating frame 1. An electromagnetic pressure relief valve 12 is fixed within the pressure relief channel 11. Furthermore, a drive impeller 13 is rotatably connected within the pressure relief channel 11, a lower pressure frame 14 is slidably connected within the heating frame 1, a cleaning roller 15 is rotatably connected within the lower pressure frame 14, and multiple cleaning steel strips 16 are fixed on the roller surface of the cleaning roller 15. A transmission bevel gear 17 is coaxially fixedly connected to the drive impeller 13, and a transmission bevel gear 2 18 is rotatably connected within the heating frame 1. The transmission bevel gear 2 18 meshes with the transmission bevel gear 17, and a transmission bevel gear 5 60 is coaxially fixedly connected to the transmission bevel gear 2 18. A transmission bevel gear 625 is rotatably connected inside the heating frame 1. The transmission bevel gear 60 meshes with the transmission bevel gear 625, and a cross transmission rod 19 is coaxially fixedly connected to the transmission bevel gear 625. A transmission worm gear 20 is rotatably connected inside the lower pressure frame 14. A cross transmission hole 21 is opened on the transmission worm gear 20. The cross transmission rod 19 is inserted into the cross transmission hole 21. A transmission worm wheel 22 is coaxially fixedly connected to the cleaning roller 15, and the transmission worm wheel 22 meshes with the transmission worm gear 20.

[0043] The steel billet can be clamped and fixed by the clamping frame 7. During the fixing process, the servo motor 9 drives the conveying wheel 8 to rotate, and the conveying wheel 8 conveys the steel billet into the heating frame 1. The steel billet is heated by the induction heating coil 10 in the heating frame 1. Although the induction heating coil 10 does not directly heat the air during the heating process, the high temperature of the steel surface during the heating process causes the surrounding air to expand due to heat, increasing its volume. The air inside the heating frame 1 expands in volume after being heated, decreasing in density and weight, so the hot air flows upward and accumulates at the top of the heating channel 2. At this time, the pressure relief channel 11 guides and transports this high-pressure, high-temperature gas. During the transport process, the high-pressure, high-temperature gas blows the drive impeller 13. After the drive impeller 13 rotates, it drives the transmission bevel gear 17 to rotate. After the transmission bevel gear 17 rotates, it drives the transmission bevel gear 18 to rotate. After the transmission bevel gear 18 rotates, it drives the transmission bevel gear 60 to rotate. The fifth gear 60 drives the transmission bevel gear 625 to rotate, which in turn drives the cross transmission rod 19 to rotate. The cross transmission rod 19 then drives the transmission worm gear 20 to rotate through the insertion and engagement with the cross transmission hole 21. The transmission worm gear 20 drives the cleaning roller 15 to rotate, and the rotation direction of the cleaning roller 15 is opposite to the direction of the billet conveying, so that the cleaning steel bar 16 can cooperate with the billet conveying action to roll and rub the surface of the billet. The energy stored in the high-pressure gas (e.g., 30MPa) can be released through the throttle valve to drive equipment such as the pneumatic catapult. Its energy density is far greater than that of lithium batteries (up to 120kJ / L). Therefore, by accumulating pressure and releasing the pressure of the high-pressure gas, the above-mentioned rolling action can be achieved, cleaning the iron oxide layer generated after the billet is heated, improving the effect of subsequent rolling. Furthermore, the pressure relief valve 12 controls the degree of pressure relief, thereby further controlling the speed of the drive impeller 13 by adjusting the degree of pressure relief, and further controlling the washing efficiency.

[0044] The drive assembly includes a control screw 23 rotatably connected within two stabilizer arms 6 and a servo motor 24 fixedly connected within two stabilizer arms 6. The output shaft of each servo motor 24 is coaxially fixedly connected to the corresponding control screw 23, and each control screw 23 is threadedly connected to the corresponding clamping frame 7.

[0045] With the above structure, the control screw 23 can be rotated by the servo motor 24. After the control screw 23 rotates, it will push the corresponding clamping frame 7 to move, thereby further realizing the relative or opposite movement of the two clamping frames 7, completing the clamping effect of the steel billet, and facilitating the normal operation of subsequent conveying work.

[0046] The annular track frame 4 has an annular guide groove 26. Each of the two stabilizing arms 6 is rotatably connected to a follower wheel 27. The wheel surface of each follower wheel 27 is in contact with the annular guide groove 26. Each of the two stabilizing arms 6 is rotatably connected to a drive wheel 28. Each of the two stabilizing arms 6 has a servo motor 29 fixed inside. The output shaft of each servo motor 29 is coaxially fixedly connected to the corresponding drive wheel 28. The wheel surface of each drive wheel 28 is in contact with the surface of the annular track frame 4.

[0047] With the above structure, the drive wheel 28 can be rotated by the servo motor 29. The drive wheel 28, by contacting the surface of the ring track frame 4, drives the two stabilizing arms 6, the conveying frame 5 and other structures to rotate as a whole. In this way, the entire steel billet can be rotated at an angle during the clamping process, thereby improving the uniformity of heating.

[0048] A pair of oppositely arranged bonding frames 30 are fixed on the conveying frame 5. Each bonding frame 30 has a bonding groove 31. Each bonding groove 31 is slidably connected to a wheel seat 32. Each wheel seat 32 is rotatably connected to a bonding wheel 33. A bonding spring 34 is fixed between each wheel seat 32 and the bottom of the corresponding bonding groove 31.

[0049] With the above structure, the sliding wheel seat 32 can be adjusted according to the thickness of the steel billet, and the wheel seat 32 is pushed by the contact spring 34 so that the wheel surface of the contact wheel 33 is always in contact with the surface of the steel billet.

[0050] A second pressure frame 35 is slidably connected inside the heating frame 1, and a connecting rod 36 is fixed on both the first pressure frame 14 and the second pressure frame 35. The top end of each connecting rod 36 extends out of the heating frame 1 and is fixed with a counterweight 37. A guide roller 38 is rotatably connected to the top surface of the second pressure frame 35. The roller surface of the guide roller 38 contacts the surface of the steel billet. A striking component is provided on the second pressure frame 35, and the guide roller 38 is connected to the striking component.

[0051] With the above structure, the counterweight 37 can apply pressure to the lower pressure frame 14 and the lower pressure frame 35, so that the lower pressure frame 14 and the lower pressure frame 35 can always be in contact with the surface of the billet. When the billet is conveyed, the billet can drive the guide roller 38 to rotate. After the guide roller 38 rotates, it will drive the striking component to strike the billet, causing the billet to vibrate. When the billet vibrates rapidly, the impurities on the billet surface tend to maintain their original motion state (stationary or low-speed movement) due to inertia. The high-frequency oscillation of the billet surface causes the impurities to be relatively displaced from the billet surface, and finally detach from the billet surface, further improving the cleaning effect of the iron oxide layer on the billet.

[0052] The striking assembly includes a sliding groove 61 opened in the lower pressure frame 35, a striking block 39 slidably connected in the sliding groove 61, and a transmission gear 40 and a transmission gear 41 rotatably connected in the lower pressure frame 35. A sector gear 42 is coaxially fixedly connected to the transmission gear 41. The transmission gear 40 is coaxially fixedly connected to the guide roller 38. A rack 43 is fixed on one side of the striking block 39. The rack 43 meshes with the sector gear 42. A transmission belt 45 is connected to the transmission gear 40 and the transmission gear 41. A push spring 44 is fixed between the bottom of the sliding groove 61 and the striking block 39.

[0053] With the above structure, the guide roller 38 drives the transmission gear 40 to rotate. After the transmission gear 40 rotates, it drives the transmission gear 41 to rotate through the transmission belt 45. After the transmission gear 41 rotates, it drives the sector gear 42 to rotate. After the sector gear 42 rotates, the tooth segment of the sector gear 42 meshes with the rack 43. The sector gear 42 then drives the striking block 39 to rise. When the missing tooth part of the sector gear 42 contacts the rack 43, the striking block 39 loses its restraint, the push spring 44 releases the pressure, and pushes the striking block 39 down, thereby realizing the striking work. Furthermore, through the continuous rotation of the sector gear 42, the striking block 39 can achieve continuous striking.

[0054] The cleaning roller 15 is hollow inside and has a vibrating rod 46 rotatably connected inside. Multiple support rods 47 are arranged and fixed on the vibrating rod 46. A push spring 48 is fixed to one end of each support rod 47. A vibrating block 49 is fixed to each push spring 48. Multiple resonant steel blocks 50 are arranged and fixed on the inner wall of the cleaning roller 15. Each vibrating block 49 is engaged with a corresponding resonant steel block 50. Each resonant steel block 50 is fixedly connected to a corresponding cleaning steel strip 16.

[0055] With the above structure, the vibrating rod 46 can rotate inside the cleaning roller 15. After the vibrating rod 46 rotates, it will drive each support rod 47 to rotate as a whole, and further drive each vibrating block 49 to rotate. During the overall rotation, each vibrating block 49 will continuously strike the corresponding resonant steel block 50, causing the resonant steel block 50 to vibrate. This vibration force is guided to the cleaning steel bar 16, so that when the cleaning steel bar 16 comes into contact with the iron oxide scale generated on the steel billet, it can apply vibration force to it, thereby improving the cleaning effect.

[0056] The bottom surface of the lower pressure frame 14 is rotatably connected to a follower roller 51. The roller surface of the follower roller 51 is in contact with the surface of the steel billet, and a transmission gear 3 52 is coaxially fixedly connected to the follower roller 51. A transmission gear 4 53 is coaxially fixed to the vibrating rod 46, and a transmission toothed belt 2 54 is connected to the transmission gear 3 52 and the transmission gear 4 53.

[0057] With the above structure, during the billet conveying process, the billet drives the follower roller 51 to rotate. After the follower roller 51 rotates, it drives the transmission gear 3 52 to rotate. After the transmission gear 3 52 rotates, it drives the transmission gear 4 53 to rotate through the transmission belt 2 54. The transmission gear 4 53 then drives the vibrating rod 46 to rotate.

[0058] Multiple conveying rollers 55 are rotatably connected to the bottom of the heating channel 2, and a waste collection chamber 56 located at the bottom of the heating channel 2 is opened in the heating frame 1, and the opening of the waste collection chamber 56 is connected to the heating channel 2.

[0059] With the above structure, the cleaned iron oxide scale can be collected through the waste collection chamber 56.

[0060] The heating frame 1 has a placement port 57 that connects to the waste collection chamber 56. A collection box 58 is slidably inserted into the placement port 57, and an operating handle 59 is fixed on the collection box 58.

[0061] With the above structure, the iron oxide scale that falls into the collection box 58 can be collected through the waste collection chamber 56, making it convenient for personnel to handle it uniformly later.

[0062] The working principle of this invention is as follows: A servo motor 24 drives a control screw 23 to rotate. The rotation of the control screw 23 pushes the corresponding clamping frame 7 to move, thereby achieving relative or opposite movement of the two clamping frames 7 and completing the clamping effect on the steel billet. During the fixing process, a servo motor 9 drives a conveyor wheel 8 to rotate. The conveyor wheel 8 conveys the steel billet into the heating frame 1. The steel billet is heated inside the heating frame 1 by an induction heating coil 10. During the heating process, high temperatures are generated inside the heating frame 1. The air inside the heating frame 1 expands in volume, decreases in density, and becomes lighter, causing the hot air to rise and accumulate at the top of the heating channel 2. At this time, the pressure relief channel 11 guides and transports this high-pressure, high-temperature gas. During the process, high-pressure, high-temperature gas blows the drive impeller 13. The rotation of the drive impeller 13 drives the first transmission bevel gear 17 to rotate, which in turn drives the second transmission bevel gear 18 to rotate. The second transmission bevel gear 18 then drives the fifth transmission bevel gear 60 to rotate, which in turn drives the sixth transmission bevel gear 25 to rotate. The sixth transmission bevel gear 25 then drives the cross transmission rod 19 to rotate. The cross transmission rod 19, through its insertion into the cross transmission hole 21, drives the transmission worm gear 20 to rotate. The transmission worm gear 20 then drives the cleaning roller 15 to rotate, with the rotation direction of the cleaning roller 15 opposite to the billet conveying direction. This allows the cleaning steel bar 16 to cooperate with the billet conveying action, cleaning the surface of the billet. The rolling process removes the iron oxide layer generated after heating the steel billet, improving the subsequent rolling effect. The pressure relief valve 12 controls the pressure relief level, which in turn controls the speed of the drive impeller 13, further regulating the washing efficiency. The counterweight 37 applies pressure to the lower pressure frame 14 and lower pressure frame 35, ensuring they remain in constant contact with the billet surface. During billet transport, the billet drives the guide roller 38 to rotate, which in turn drives the transmission gear 40. The rotation of the transmission gear 40, in turn, drives the transmission gear 41 via the transmission belt 45. The rotation of the transmission gear 41, in turn, drives the sector gear 42. When the sector gear 42 rotates, its teeth mesh with the rack 43, causing the striking block 39 to rise. When the missing tooth of the sector gear 42 contacts the rack 43, the striking block 39 loses its restraint, the push spring 44 releases pressure, and pushes the striking block 39 downward, thus achieving the striking operation. Furthermore, through the continuous rotation of the sector gear 42, the striking block 39 can achieve continuous striking. During the billet conveying process, the billet drives the follower roller 51 to rotate. The rotation of the follower roller 51 then drives the transmission gear 3 52 to rotate. The rotation of the transmission gear 3 52, in turn, drives the transmission gear 4 53 to rotate via the transmission belt 2 54. The transmission gear 4 53 then drives the vibrating rod 46 to rotate.The vibrating rod 46 rotates inside the cleaning roller 15. This rotation drives each support rod 47 to rotate as a whole, further rotating each vibrating block 49. During this rotation, each vibrating block 49 repeatedly strikes its corresponding resonant steel block 50, causing it to vibrate. This vibration force is then directed to the cleaning steel bar 16, allowing it to apply vibration force to the iron oxide scale on the steel billet, thus improving the cleaning effect. The iron oxide scale is collected in the waste collection chamber 56 and falls into the collection box 58 for convenient and unified processing.

[0063] In summary, the steel billet is clamped and fixed by the clamping frame 7. During the fixing process, the servo motor 9 drives the conveyor wheel 8 to rotate, which conveys the steel billet into the heating frame 1. Inside the heating frame 1, the steel billet is heated by the induction heating coil 10. During the heating process, high temperature is generated inside the heating frame 1. The air inside the heating frame 1 expands in volume after being heated, its density decreases, and its weight becomes lighter. As a result, the hot air flows upward and accumulates at the top of the heating channel 2. At this time, the pressure relief channel 11 guides and transports this high-pressure, high-temperature gas. During the transport process, the high-pressure, high-temperature gas blows the drive impeller 13. After the drive impeller 13 rotates, it drives the transmission bevel gear 17 to rotate. After the transmission bevel gear 17 rotates, it will... The transmission bevel gear 18 rotates, which in turn drives the cross transmission rod 19 to rotate. The cross transmission rod 19 then drives the transmission worm gear 20 to rotate through the insertion and engagement with the cross transmission hole 21. The transmission worm gear 20 drives the cleaning roller 15 to rotate, and the rotation direction of the cleaning roller 15 is opposite to the direction of the billet conveying. This allows the cleaning steel bar 16 to cooperate with the billet conveying action to roll and rub the surface of the billet, cleaning the iron oxide layer generated after the billet is heated, improving the effect of subsequent rolling. Furthermore, the pressure relief valve 12 controls the degree of pressure relief, thereby further controlling the speed of the drive impeller 13 by adjusting the degree of pressure relief, and further controlling the washing efficiency.
