Description

Technical Field

[0001] The present invention relates to the technical field of steel processing, and particularly to an annealing furnace for steel processing. Background Art

[0002] Steel processing mainly includes various methods such as hot rolling, forging, extrusion, cold rolling, etc. Among them, forging is the process of forging an ingot into steel, billet or forging blank using equipment such as forging hammers, precision forging machines, quick forging machines or hydraulic presses. It can produce finished steel with better mechanical properties and unique shapes. During the forging process of steel, an annealing furnace is needed to heat-treat the steel. Through the processes of heating and cooling, the internal organizational structure of the steel is adjusted, thereby changing its physical and mechanical properties. Therefore, we introduce an annealing furnace for steel processing.

[0003] The existing patent (Publication No.: CN118726740B) discloses an annealing furnace with automatic temperature control, including a chassis, a furnace base, an inner cover and a cooling cover arranged on the furnace base, a cold air blower, a top cover, a liquid spraying mechanism, a swinging mechanism and a locking mechanism. The liquid spraying mechanism includes a liquid outlet pipe seat, a connecting ring, a liquid spraying pipe seat, at least two first spraying pipes arranged in a ring on the liquid spraying pipe seat, an installation box, a bearing bracket and a second spraying pipe rotatably arranged on each bearing bracket. A number of nozzles are equidistantly arranged along the axis of each first spraying pipe, and the axis of the nozzle is perpendicular to the axis of the first spraying pipe. The swinging mechanism has a swinging output end, and the swinging output end is used to synchronously drive a number of second spraying pipes to swing around the bearing bracket. The locking mechanism includes a number of positioning arc plates and abutting blocks slidably arranged along the radial direction of the chassis. This device can uniformly cool the inner cover in all directions during the cooling stage of the annealing furnace, improving the production quality. In the prior art, during the annealing process of steel, due to the high carbon content of the steel, surface decarburization or oxidation reactions may occur during the annealing process, forming a small amount of carbon slag or oxides. These carbon slag, etc. fall on the furnace base, and after each annealing, it is necessary to manually clean the carbon slag on the furnace base, increasing the labor intensity of workers.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1 to 8 , the present invention provides a technical solution: an annealing furnace for steel processing, including a furnace base 1, an inner cover 2 and a heating cover 3. A drive assembly 4 is provided in the middle of the top surface of the furnace base 1, and a heat insulation layer 5 is covered outside the drive assembly 4. A lifting assembly 6 is provided in the middle of the furnace base 1. The top of the drive assembly 4 is fixedly connected with a cleaning assembly 7. The top of the lifting assembly 6 is rotatably connected with a rotating table 8, and a discharging assembly 9 is provided on the top surface of the rotating table 8.

[0030] In this embodiment, as Figure 1 , Figures 3 to 5 and Figure 8As shown in the figure, the cleaning component 7 includes a support shaft 701 fixedly connected to the top of the driving component 4 and a rotating wall 702 movably connected to the middle of the lifting component 6. A guiding cover 703 is integrally formed at the top end of the support shaft 701. A central shaft 704 is fixedly connected to the top of the guiding cover 703. A sliding groove 705 is formed on the outer surface of the central shaft 704. A sliding block 706 is slidably connected inside the sliding groove 705. One side of the sliding block 706 extending outside the sliding groove 705 is hinged with an expansion connecting rod 707. One end of the expansion connecting rod 707 away from the sliding block 706 is hinged with an inner scraping strip 708. A limiting strip 709 is integrally formed in the middle of the outer surface of the central shaft 704. A rotating ring 7010 is integrally formed at the bottom of the rotating wall 702. An arc-shaped fitting groove is formed on the outer ring of the rotating ring 7010, and a contact ball 7011 is fitted inside the arc-shaped fitting groove. A spring telescopic rod 7012 is fixedly connected to the outer surface of the contact ball 7011. A hanging ring 7013 is integrally formed in the middle of the outer ring of the rotating wall 702. A collecting groove 7014 is hung in the middle of the hanging ring 7013, and the top of the side of the collecting groove 7014 in contact with the rotating wall 702 inclines towards the outer ring of the collecting groove 7014. An outer scraping strip 7015 and a torsion spring 7016 are respectively fixedly connected to the top surface of the rotating wall 702. A pawl 7017 is fixedly connected to the top end of the torsion spring 7016;The outer scraping strip 7015 is composed of two vertical parts and one horizontal part, and there is a gap between the horizontal part and the top surface of the unloading plate 905. When the unloading plate 905 is unloading, it rotates around the connecting shaft on the side close to the outer ring of the rotating table 8, and the unloading plate 905 tilts with the side close to the middle of the rotating table 8 being lifted during unloading. Therefore, the lifting height of the side of the unloading plate 905 close to the horizontal part of the outer scraping strip 7015 decreases gradually and will not interfere with the horizontal part of the outer scraping strip 7015. When it is necessary to scrape the carbon slag and scale on the inner surface of the steel coil, the motor 401 drives the sun gear 402 to rotate, and the support shaft 701 rotates synchronously with the sun gear 402. The support shaft 701 drives the central shaft 704 and the guide cover 703 to rotate synchronously. At this time, the motor 401 rotates forward, that is, the central shaft 704 rotates towards the opening side of the limit strip 709. Since the sliding block 706 is slidably connected to the sliding groove 705 and the central shaft 704 suddenly accelerates, a relative displacement is generated between the sliding block 706 and the central shaft 704, causing the sliding block 706 to slide along the sliding groove 705 to the side close to the closed side of the limit strip 709. The limit strip 709 blocks the inner scraping strip 708 to prevent the inner scraping strip 708 from unfolding under the action of centrifugal force. If the inner scraping strip 708 cannot unfold, it will not clean the carbon slag and scale on the inner surface of the steel coil. When the motor 401 rotates in reverse, the sliding block 706 slides along the sliding groove 705 towards the opening side of the limit strip 709. At this time, the inner scraping strip 708 loses the block of the limit strip 709, and the sliding block 706 moves to the end of the sliding groove 705. Therefore, the central shaft 704 can drive the sliding block 706 to rotate at a high speed. When the sliding block 706 rotates at a high speed, a centrifugal force is generated, throwing up the expansion connecting rod 707, causing the expansion connecting rod 707 to change from a vertical state to a horizontal state, thereby opening the inner scraping strip 708 and enabling the inner scraping strip 708 to scrape the carbon slag and other impurities on the inner surface of the steel coil, realizing the rapid cleaning of the carbon slag on the surface of the steel. It should be noted in the driving assembly 4 that there is a speed difference between the sun gear 402 in the middle and the gear ring 404. The sun gear 402 rotates faster, and the faster rotation speed of the sun gear 402 drives the fan blade 407 to rotate to generate wind power, while the gear ring 404 rotates slowly to drive the rotating table 8 to rotate slowly, preventing the steel coil from being thrown out of the rotating table 8 due to too fast a rotation speed. In addition, the problem of the speed difference also acts on the support shaft 701 and the rotating disk 901. Therefore, the rotating disk 901 and the support shaft 701 are set to be rotatably connected without interference, and at the same time, the problem that the rotation speed of the rotating table 8 is the same as that of the support shaft 701, resulting in the relative static state of the inner scraping strip 708 driven by the support shaft 701 and the steel coil rotation speed, causing the problem that the inner scraping strip 708 cannot clean the inner surface of the steel coil is avoided.;

[0031] In this embodiment, as Figure 4 and Figures 6 to 7As shown in the figure, the unloading assembly 9 includes a rotating disk 901 rotatably connected to the middle of the support shaft 701. One end of the outer ring of the rotating disk 901 is hinged with a rocker 902. One end of the rocker 902 far from the rotating disk 901 is fixedly connected with a limiting rod 903. Both ends of the limiting rod 903 are slidably inserted into the inside of the straight slot 904. The straight slot 904 is opened in the middle of the bottom surface of the unloading plate 905. One side of the unloading plate 905 far from the rotating disk 901 is rotatably connected to the edge of the top surface of the rotating table 8 through a connecting shaft. The unloading plate 905 is fan-shaped, and refractory fiber cloth 906 is fixedly connected to the two straight edges of the unloading plate 905; the operation of the unloading assembly 9 is affected by the weight of the steel coil placed above the rotating table 8. When a steel coil is placed on the rotating table 8, the rotating table 8 will be pressed down under the action of gravity. The downward movement of the rotating table 8 will drive the lifting seat 602 below to descend synchronously. The lifting seat 602 compresses the return spring 601. When in the compressed state, the rocker 902 is in a horizontal state. At this time, the unloading plate 905 fits on the top surface of the rotating table 8. When the cleaning assembly 7 finishes cleaning the carbon slag on the surface of the steel coil, the carbon slag falls on the unloading plate 905 and the refractory fiber cloth 906. After annealing, the steel coil is lifted from the rotating table 8. After losing the pressure from the steel coil, the return spring 601 rebounds, thereby pushing the lifting seat 602 to move upward. The upward movement of the lifting seat 602 drives the rotating table 8 to move upward. At this time, the relative height between the rotating table 8 and the rotating disk 901 changes. The rotating disk 901 descends relative to the rotating table 8. The downward movement of the rotating disk 901 will drive one end of the rocker 902 far from the unloading plate 905 to move downward. At this time, the rocker 902 will take the top opening edge of the central circulation channel 802 of the rotating table 8 as the fulcrum, lift the end of the rocker 902 connected to the unloading plate 905, and drive the limiting rod 903 to slide along the straight slot 904. At this time, the unloading plate 905 will rotate around the connecting shaft connecting it to the rotating table 8, so that the part of the unloading plate 905 close to the middle of the rotating table 8 is lifted and tilted, so that the carbon slag and scale on the unloading plate 905 slide down to the top of the lifting seat 602. Since the inner diameter of the top of the lifting seat 602 is smaller than the outer diameter of the rotating table 8, and the top surface of the lifting seat 602 is an inclined surface, the carbon slag will slide down along the top of the lifting seat 602 into the collection tank 7014 to complete automatic collection without manual cleaning.

[0032] In this embodiment, as Figures 3 to 4 and Figure 6As shown in the figure, the driving component 4 includes a motor 401 fixedly connected to the middle of the top surface of the furnace base 1. The output end of the motor 401 is fixedly penetrated with a sun gear 402. The outer ring of the sun gear 402 meshes with a planetary gear 403. One side of the planetary gear 403 away from the sun gear 402 meshes with a ring gear 404. The output end of the motor 401 is fixedly connected with a fan blade 407. The tooth height of the inner ring of the ring gear 404 is greater than the tooth height of the outer ring of the planetary gear 403. The top of the ring gear 404 is fixedly connected to the bottom surface of the rotating table 8. The middle of the bottom surface of the planetary gear 403 is rotatably connected with a rotating shaft 405, and the bottom end of the rotating shaft 405 penetrates through the heat insulation layer 5 and is fixedly connected to the top surface of the furnace base 1. The upper half of the ring gear 404 is provided with a first ventilation opening 406. The outer ring of the rotating table 8 is integrally formed with ratchet teeth 801. A circulation channel 802 is provided in the middle of the rotating table 8. The top edge of the circulation channel 802 is fixedly connected with an annular blocking plate 803, and the top surface height of the annular blocking plate 803 is higher than the top surface height of the discharge plate 905. An annular limiting groove is provided on the bottom surface of the rotating table 8. The lifting component 6 includes a return spring 601 fixedly connected to the top surface of the furnace base 1. The top end of the return spring 601 is fixedly connected with a lifting seat 602. Plugging rods 603 are equiangularly distributed on the bottom edge of the lifting seat 602. A limiting ring 604 is integrally formed on the top surface of the lifting seat 602. A second ventilation opening 605 is provided on the side wall of the lifting seat 602. The limiting ring 604 is rotatably connected with the annular limiting groove provided on the bottom surface of the rotating table 8;During the annealing process, the motor 401 in the driving component 4 is started to drive the fan blade 407 to rotate forward. The rotation of the fan blade 407 generates wind force, blowing air from the circulation channel 802 into the channel formed by the inner ring of the steel coil, and finally blowing it out to the inner top of the inner cover 2. Subsequently, this part of the air diffuses around after hitting the inner top of the inner cover 2. At the same time, a negative pressure is generated below the fan blade 407, sucking the air between the outer ring of the steel coil and the inner wall of the inner cover 2 into the middle of the gear ring 404 through the first vent 406 and the second vent 605, and then blowing it upward through the fan blade 407 again to form a cycle, so that the hot air in the inner cover 2 circulates continuously, ensuring that the steel coil is heated evenly everywhere during the annealing process and the annealing effect is better. In addition, when the motor 401 rotates forward, it will also drive the sun gear 402 to rotate. The rotation of the sun gear 402 will drive the gear ring 404 to rotate through the planet gear 403. It should be noted that the rotation direction of the gear ring 404 is opposite to that of the sun gear 402. The rotation of the gear ring 404 will drive the rotating table 8 at the top to rotate. At this time, the outer ring ratchet teeth 801 of the rotating table 8 will mesh with the ratchet pawl 7017, that is, the rotating table 8 can drive the rotating wall 702 to rotate through the ratchet pawl 7017, so that the rotating wall 702 and the rotating table 8 remain relatively stationary, that is, the outer scraping strip 7015 on the rotating wall 702 and the rotating table 8 remain relatively stationary. This structure is to prevent the outer scraping strip 7015 from continuously rubbing the surface of the steel coil during the annealing process, which will increase the wear of the outer scraping strip 7015 over time. Similarly, if the motor 401 rotates in reverse, the rotating table 8 will rotate in the reverse direction. At this time, the ratchet teeth 801 and the ratchet pawl 7017 will not mesh, and the rotating table 8 and the rotating wall 702 will rotate relative to each other. Also, because there is a steel coil placed on the rotating table 8, the outer scraping strip 7015 can scrape the carbon slag and scale on the outer surface of the steel coil at this time. The spring telescopic rod 7012 is installed in the middle of the inner side of the lifting seat 602. The resilience of the spring telescopic rod 7012 presses the abutting ball 7011 into the spherical groove on the outer ring of the rotating ring 7010. This structure mainly increases the friction between the rotating ring 7010 and the lifting seat 602 to prevent the rotating table 8 from driving the rotating wall 702 to rotate when the ratchet teeth 801 and the ratchet pawl 7017 are not meshed. The tooth height of the inner ring of the gear ring 404 is greater than the tooth height of the outer ring of the planet gear 403 to ensure that the gear ring 404 can still maintain meshing with the planet gear 403 when rising with the rotating table 8 and prevent the transmission from being interrupted.;

[0033] The usage method and advantages of the present invention: When this annealing furnace for steel processing is in use, the working process is as follows:

[0034] The driving component 4 drives the fan blade 407 to rotate, causing the hot air inside the inner cover 2 to rotate, ensuring uniform heating of all parts of the steel coil and improving the heating effect. The heat during heating comes from the high-speed burners on the heating hood 3. The basic structure of the heating hood 3 is prior art and will not be elaborated here. After annealing, the motor 401 rotates in reverse to drive the cleaning component 7 to operate, simultaneously scraping off the scale and oxide skin generated on the inner and outer surfaces of the steel coil. After cleaning, the scraped impurities fall on the discharge plate 905. When the steel coil is lifted away, the lifting component 6 rebounds to lift the rotating table 8, automatically triggering the discharge component 9 to slide the impurities on the discharge plate 905 into the collection tank 7014, realizing rapid cleaning of the top surface of the rotating table 8 and reducing the manual labor intensity.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
