Description

Technical Field

[0001] This invention relates to the field of stainless steel strip annealing technology, and more specifically to a stainless steel strip annealing apparatus. Background Technology

[0002] In the stainless steel production process, freshly produced stainless steel strips often exhibit carbide precipitation, lattice defects, and inconsistent microstructure, leading to a decrease in corrosion resistance. Therefore, annealing is necessary. Annealing is a metal heat treatment process that involves slowly heating the metal to a certain temperature, holding it for a sufficient time, and then cooling it at an appropriate rate. The purpose is to reduce hardness, improve machinability, reduce residual stress, stabilize dimensions, and reduce deformation and cracking tendency; refine grains, adjust microstructure, and eliminate microstructural defects. More precisely, annealing is a heat treatment process for materials, including both metallic and non-metallic materials, and the annealing objectives for new materials differ from those of traditional metal annealing.

[0003] Stainless steel strips are mostly stored in coils. When unwinding stainless steel coils, uneven force may cause them to shift and slip. When they shift and slip, they may bend and misalign, making it difficult to anneal. Furthermore, during annealing, dust and other impurities on the surface of stainless steel strips often adhere to them, which greatly reduces the quality of the stainless steel strips. Therefore, we have proposed an annealing device for stainless steel strips. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a stainless steel strip annealing device, including an annular square shell, an anti-slip mechanism fixedly connected to one side of the annular square shell, a stainless steel strip sleeve fitted and slidably connected to the outer surface of the anti-slip mechanism, a handle fixedly connected to one side of the stainless steel strip, a side sleeve rod fitted and slidably connected to the outer surface of the handle, a smoothing mechanism fixedly connected to the inner wall of the annular square shell, an air jet mechanism fixedly connected to the bottom of the annular square shell, and a bottom cylinder fixedly connected to the bottom of the air jet mechanism.

[0005] The anti-slip mechanism includes a side corner plate. A long pull rod is threaded through and connected to one side of the side corner plate. A return spring is fixedly connected to one side of the side corner plate. A stop block is fixedly connected to the end of the return spring away from the side corner plate. An inner push spring is fixedly connected to one side of the side corner plate. An inner push plate is fixedly connected to the end of the inner push spring away from the side corner plate. A tightening ring is fitted and fixedly connected to the outer surface of the inner push plate. A clamping piece is fixedly connected to the side of the inner push plate away from the inner push spring. One side of the side sleeve rod is fixedly connected to an annular square shell. One side of the side corner plate is fixedly connected to the annular square shell. One end of the long pull rod passes through a stainless steel coil and is connected to the stainless steel coil. The sliding connection includes multiple clamping plates evenly distributed on one side of the inner push plate. The inner push plate is sleeved on the long pull rod and slidably connected to it. The stop block resists the long pull rod under the pull force to prevent it from sliding towards the stop block during subsequent rotation. The two inner push plates push the stainless steel strip to the middle position to prevent the stainless steel strip from shifting or misaligning due to uneven force direction during unwinding. The clamping plates on one side of the inner push plate will engage with the gaps in the stainless steel strip to separate it, preventing the stainless steel strip from being wound too tightly and difficult to unwind. The tightening ring tightens the stainless steel strip inward to prevent it from loosening during unwinding after the gaps between the stainless steel strips are separated.

[0006] Furthermore, the smoothing mechanism includes a side plate, a compression spring fixedly connected to the bottom of the side plate, a push plate fixedly connected to the bottom of the compression spring, an upper through rod fixedly connected to the top of the push plate, a V-shaped plastic plate fixedly connected to one side of the push plate, side brushes fixedly connected to both sides of the V-shaped plastic plate, one side of the side plate fixedly connected to the inner wall of the annular square shell, one side of the push plate slidably connected to the inner wall of the annular square shell, multiple side brushes evenly distributed on both sides of the V-shaped plastic plate, and the top of the upper through rod penetrating the side plate and connecting with... The side plates are slidably connected, and the downward spring pushes the push plate against the stainless steel strip through its extension force. This prevents the stainless steel strip from being completely laid flat at the bottom of the annular square shell during unwinding. At the same time, the upper through rod at the top of the push plate passes through the side plates to limit the push plate and prevent it from moving together with the sliding stainless steel strip when in contact with it. The side brushes on the V-shaped plastic plate clean the sliding stainless steel strip to prevent a large amount of dust from adhering to the surface of the stainless steel strip and affecting the annealing quality. The dust is pushed to both sides of the V-shaped plastic plate for discharge, preventing excessive dust accumulation on both sides of the V-shaped plastic plate from affecting the cleaning effect.

[0007] Further, the jetting mechanism includes a heating plate with an exhaust port at its top and a bottom square shell fixedly connected to its bottom. An internal cleaning assembly is fixedly connected to the bottom of the inner wall of the bottom square shell. An air pump is connected to the bottom of the bottom square shell. A cooling strip is slidably connected through one side of the bottom square shell. A side arc plate is fixedly connected to the top of the heating plate, with a side arc hole on one side. A long connecting plate is fixedly connected to one side of the side arc plate, with an arc-shaped baffle on one side. A dust-blocking hole is opened on one side of the arc-shaped baffle. An inner arc lever is fixedly connected to one side of the side arc plate, with a vent hole on one side. One side of the long connecting plate is fixedly connected to the inner wall of the annular square shell. One side of the side arc plate penetrates the annular square shell and is fixedly connected to it. The top of the heating plate is fixedly connected to the annular square shell, and the bottom of the bottom square shell is fixedly connected to a bottom cylinder. Next, multiple ventilation holes are provided and evenly distributed on the inner arc-shaped baffle, multiple dust-blocking holes are provided and evenly distributed on the arc-shaped baffle, and multiple exhaust holes are provided and evenly distributed on the heating plate. Gas is discharged from the bottom square shell through the exhaust holes to blow air and clean the bottom of the stainless steel strip, preventing excessive dust from adhering to the bottom surface of the stainless steel strip and affecting the annealing quality. When the gas passes through the dust-blocking holes, the dust blown away is blocked at the bottom of the arc-shaped baffle, preventing the cleaned dust from repeatedly adhering to the surface of the stainless steel strip with the airflow. The dust is discharged out of the annular square shell through the side arc holes, preventing excessive dust from accumulating at the bottom of the arc-shaped baffle and blocking the dust-blocking holes. The gas is guided to the middle part of the stainless steel strip through the arc-shaped setting of the side arc plate to blow air and clean the dust, preventing dust and other debris adhering to the top surface of the stainless steel strip from being difficult to clean. The gas blows the inner arc-shaped baffle towards the arc-shaped baffle to scrape away the dust, preventing the difficult-to-blow dust clumps adhering to the surface of the stainless steel strip from being difficult to clean.

[0008] Furthermore, the internal cleaning assembly includes a pull-down spring, a square scraper blade fixedly connected to the top of the pull-down spring, a curved ring plate rotatably connected to the top of the square scraper blade, an inclined connecting plate fixedly connected to the inner wall of the curved ring plate, a central circular block fixedly connected to the side of the inclined connecting plate away from the curved ring plate, an upper brush fixedly connected to the top of the inclined connecting plate, a plastic ring fixedly connected to the top of the square scraper blade, an internal brush fixedly connected to the inner wall of the plastic ring, the bottom of the pull-down spring fixedly connected to the inner wall of the bottom square shell, both sides of the square scraper blade slidably connected to the inner wall of the bottom square shell, two curved ring plates evenly distributed on the square scraper blade, multiple inclined connecting plates evenly distributed on the inner wall of the curved ring plate, and multiple internal brushes. The upper brushes are evenly distributed on the plastic ring. Multiple upper brushes are evenly distributed on the inclined connecting plate. The square scraper blades slide and scrape the bottom square shell to prevent dust from adhering to the inner wall of the bottom square shell. The inclined connecting plate is tilted and rotates to diffuse air upwards towards the square scraper blades, preventing the gas passing through the curved ring plate from being difficult to spray evenly from all the exhaust holes. When the upper brushes move to contact the heating plate, they rotate and clean the exhaust holes to prevent excessive dust accumulation in the exhaust holes from causing blockage. When the plastic ring unfolds outwards, it wipes and cleans the bottom of the heating plate to prevent excessive dust accumulation on the bottom surface of the heating plate from blocking the exhaust holes. As the plastic ring opens outwards, the built-in brushes on the inner wall clean the exhaust holes to prevent dust accumulation in the exhaust holes that the upper brushes cannot reach, which would affect the exhaust efficiency.

[0009] The beneficial effects of this invention are as follows:

[0010] 1. This invention uses two inner push plates to push the stainless steel strip to the middle position, preventing the stainless steel strip from shifting or misaligning due to uneven force direction during unwinding. A downward spring pushes the lower push plate to resist the stainless steel strip through its extension force, preventing the stainless steel strip from not being completely flattened at the bottom of the annular square shell during unwinding. Gas is guided to the middle part of the stainless steel strip through the arc-shaped setting of the side arc plate for blowing and dust removal, preventing dust and other debris from adhering to the top surface of the stainless steel strip and being difficult to clean. A square scraper blade slides and scrapes the bottom square shell to prevent dust from adhering to the inner wall of the bottom square shell and being difficult to clean.

[0011] 2. This invention incorporates an anti-slip mechanism. The stop block, under the pull force, blocks the long pull rod, preventing it from sliding towards the stop block during subsequent rotation. The inner push spring pushes the inner push plate to push the stainless steel strip. The two inner push plates push the stainless steel strip to the middle position, preventing the stainless steel strip from shifting or misaligning due to uneven force during unwinding. The clamping piece on one side of the inner push plate will engage with the gaps in the stainless steel strip to separate it, preventing the stainless steel strip from being wound too tightly and difficult to unwind. The tightening ring tightens the stainless steel strip inward, preventing it from loosening during unwinding after the gaps between the stainless steel strips are separated.

[0012] 3. This invention incorporates a leveling mechanism. A downward-pressing spring, through its extension force, pushes a lower push plate against the stainless steel strip, preventing the strip from being partially laid flat on the bottom of the annular square shell during unwinding. Simultaneously, an upper through-rod at the top of the lower push plate, passing through the side plate, limits the lower push plate, preventing it from moving along with the sliding stainless steel strip. Side brushes on the V-shaped plastic plate clean the sliding stainless steel strip, preventing excessive dust from adhering to its surface and affecting the annealing quality. The dust is pushed to both sides of the V-shaped plastic plate for discharge, preventing excessive dust accumulation on both sides of the plate from affecting the cleaning effect.

[0013] 4. By setting up a jet mechanism, the dust blown by the gas through the dust-blocking hole is blocked at the bottom of the arc-shaped baffle, preventing the cleaned dust from repeatedly adhering to the surface of the stainless steel strip with the airflow. The dust is discharged out of the annular square shell through the side arc hole, preventing excessive dust accumulation at the bottom of the arc-shaped baffle from blocking the dust-blocking hole and making it difficult to ventilate. The gas is guided to the middle part of the stainless steel strip by the arc-shaped setting of the side arc plate for blowing and dust removal, preventing dust and other debris from adhering to the top surface of the stainless steel strip and being difficult to clean. The gas blown to the top surface of the stainless steel strip continues to blow from the bottom towards the arc-shaped baffle. The gas blows the inner arc blade towards the arc-shaped baffle to scrape it off, preventing dust that is difficult to blow away from adhering to the surface of the stainless steel strip and is difficult to clean.

[0014] 5. This invention features an internal cleaning component. A square scraper blade slides and scrapes the bottom square shell, preventing dust from adhering to the inner wall of the bottom square shell and becoming difficult to clean. An inclined connecting plate, through its tilted setting and rotation, diffuses air upwards towards the square scraper blade, preventing gas passing through the curved ring plate from being evenly sprayed out from all the exhaust holes. When the upper brush moves to contact the heating plate, it rotates and cleans the exhaust holes, preventing excessive dust accumulation and blockage. When the plastic ring expands outwards, it wipes and cleans the bottom of the heating plate, preventing excessive dust accumulation on the bottom surface of the heating plate from clogging the exhaust holes. As the plastic ring expands outwards, the built-in brush on the inner wall cleans the exhaust holes, preventing dust accumulation in exhaust holes that the upper brush cannot reach, thus affecting exhaust efficiency.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0026] For the first embodiment, please refer to... Figures 1-5The present invention is an annealing device for stainless steel strip, comprising an annular square shell 1, an anti-slip mechanism 2 fixedly connected to one side of the annular square shell 1, a stainless steel coil 3 sleeved and slidably connected to the outer surface of the anti-slip mechanism 2, a handle 4 fixedly connected to one side of the stainless steel coil 3, a side sleeve 5 sleeved and slidably connected to the outer surface of the handle 4, a smoothing mechanism 6 fixedly connected to the inner wall of the annular square shell 1, an air jet mechanism 7 fixedly connected to the bottom of the annular square shell 1, and a bottom cylinder 8 fixedly connected to the bottom of the air jet mechanism 7.

[0027] The anti-slip mechanism 2 includes a side corner plate 201. A long pull rod 202 is threaded through and connected to one side of the side corner plate 201. A pull-back spring 203 is fixedly connected to one side of the side corner plate 201. A stop block 204 is fixedly connected to the end of the pull-back spring 203 away from the side corner plate 201. An inward push spring 205 is fixedly connected to one side of the side corner plate 201. An inward push plate 206 is fixedly connected to the end of the inward push spring 205 away from the side corner plate 201. An inward push plate 206 is sleeved and fixedly connected to the outer surface of the inward push plate 206. There is a tightening ring 207, and a clamping piece 208 is fixedly connected to the side of the inner push plate 206 away from the inner push spring 205. One side of the side sleeve rod 5 is fixedly connected to the annular square shell 1, and one side of the side corner plate 201 is fixedly connected to the annular square shell 1. One end of the long pull rod 202 passes through the stainless steel coil 3 and is slidably connected to the stainless steel coil 3. Multiple clamping pieces 208 are provided and evenly distributed on one side of the inner push plate 206. The inner push plate 206 is sleeved on the long pull rod 202 and is slidably connected to the long pull rod 202.

[0028] The smoothing mechanism 6 includes a side plate 601. A downward pressure spring 602 is fixedly connected to the bottom of the side plate 601. A downward push plate 603 is fixedly connected to the bottom of the downward pressure spring 602. An upward through rod 604 is fixedly connected to the top of the downward push plate 603. A V-shaped plastic plate 605 is fixedly connected to one side of the downward push plate 603. Side brushes 606 are fixedly connected to both sides of the V-shaped plastic plate 605. One side of the side plate 601 is fixedly connected to the inner wall of the annular square shell 1. One side of the downward push plate 603 is slidably connected to the inner wall of the annular square shell 1. Multiple side brushes 606 are provided and evenly distributed on both sides of the V-shaped plastic plate 605. The top of the upward through rod 604 passes through the side plate 601. It is slidably connected to the side plate 601. In use, the stainless steel roll 3 is placed between the two inner push plates 206. The long pull rod 202 is rotated from one side of the side plate 201, passing through the side plate 201 and then through the stainless steel roll 3 through the threaded engagement. At the same time, the stainless steel roll 3 is pulled open to the other side of the annular square shell 1 and fixed to the handle 4. The handle 4 is rotated to unwind the stainless steel roll 3. After the long pull rod 202 passes through the stainless steel roll 3, it passes through the other side plate 201 through the threaded engagement, which facilitates the installation and removal of the stainless steel roll 3. When the long pull rod 202 passes through the other side plate 201, it pushes the stop block 204. The long pull rod 202 and the other side plate 201 are connected. When the side corner plate 201 finishes its threaded engagement, rotating the long pull rod 202 will prevent it from moving. Simultaneously, the return spring 203 pulls back the stop block 204 with its return force. The stop block 204, under this return force, blocks the long pull rod 202. At the same time, the inner push spring 205 pushes the inner push plate 206 with its extension force, pushing the stainless steel coil 3. The two inner push plates 206 push the stainless steel coil 3 to the middle position. When the inner push plates 206 push the stainless steel coil 3, the clamping piece 208 on one side of the inner push plate 206 will engage with the gap in the stainless steel coil 3, separating it. Simultaneously, the tightening ring 207 is spread out and fitted onto the stainless steel coil 3, and the tightening ring 207 pushes inward... When the stainless steel strip 3 is tightened and slides past the bottom of the annular square shell 1, the downward pressure spring 602 pushes the downward push plate 603 to abut against the stainless steel strip 3 through the extension force. At the same time, the upward through rod 604 at the top of the downward push plate 603 passes through the side plate 601 to limit the downward push plate 603. Meanwhile, when the stainless steel strip slides, it contacts the V-shaped plastic plate 605 on one side of the downward push plate 603. The side brush 606 on the V-shaped plastic plate 605 cleans the sliding stainless steel strip. At the same time, the V-shaped plastic plate 605 accumulates the cleaned dust on both sides. As more and more dust accumulates, it is pushed to both sides of the V-shaped plastic plate 605 and discharged in conjunction with the sliding force of the stainless steel strip.

[0029] For the second embodiment, please refer to... Figures 6-9This invention provides an annealing device for stainless steel strip: the jetting mechanism 7 includes a heating plate 701, an exhaust hole 702 on the top of the heating plate 701, a bottom square shell 703 fixedly connected to the bottom of the heating plate 701, an inner cleaning component 704 fixedly connected to the bottom of the inner wall of the bottom square shell 703, an air pump 705 connected to the bottom of the bottom square shell 703, a cooling strip 706 penetrating and slidably connected to one side of the bottom square shell 703, a side arc plate 707 fixedly connected to the top of the heating plate 701, a side arc hole 708 on one side of the side arc plate 707, a long connecting plate 709 fixedly connected to one side of the side arc plate 707, and an arc-shaped baffle 710 fixedly connected to one side of the side arc plate 707. A dustproof hole 711 is provided on one side of the plate 710. An inner arc plate 712 is fixedly connected to one side of the side arc plate 707. A ventilation hole 713 is provided on one side of the inner arc plate 712. One side of the long connecting plate 709 is fixedly connected to the inner wall of the annular square shell 1. One side of the side arc plate 707 passes through the annular square shell 1 and is fixedly connected to the annular square shell 1. The top of the electric heating plate 701 is fixedly connected to the annular square shell 1. The bottom of the bottom square shell 703 is fixedly connected to the bottom cylinder 8. Multiple ventilation holes 713 are provided and evenly distributed on the inner arc plate 712. Multiple dustproof holes 711 are provided and evenly distributed on the arc baffle 710. Multiple exhaust holes 702 are provided and evenly distributed on the electric heating plate 701.

[0030] The internal cleaning assembly 704 includes a pull-down spring 7041, a square scraper blade 7042 fixedly connected to the top of the pull-down spring 7041, a curved ring plate 7043 rotatably connected through the top of the square scraper blade 7042, an inclined connecting plate 7044 fixedly connected to the inner wall of the curved ring plate 7043, a central round block 7045 fixedly connected to the side of the inclined connecting plate 7044 away from the curved ring plate 7043, an upper brush 7046 fixedly connected to the top of the inclined connecting plate 7044, a plastic ring 7047 fixedly connected to the top of the square scraper blade 7042, an internal brush 7048 fixedly connected to the inner wall of the plastic ring 7047, the bottom of the pull-down spring 7041 fixedly connected to the inner wall of the bottom square shell 703, and both sides of the square scraper blade 7042 fixedly connected to the bottom square shell 703. The inner wall of shell 703 is slidably connected. Two curved ring plates 7043 are evenly distributed on the square scraper blade 7042. Multiple inclined connecting plates 7044 are evenly distributed on the inner wall of the curved ring plates 7043. Multiple built-in brushes 7048 are evenly distributed on the plastic ring 7047. Multiple upper brushes 7046 are evenly distributed on the inclined connecting plates 7044. In use, before annealing, the air pump 705 is started to spray air onto the bottom square shell 703. The gas is discharged from the bottom square shell 703 through the exhaust hole 702 to blow dust off the bottom of the stainless steel strip. At the same time, after being discharged through the exhaust hole 702, the gas passes through the dust blocking hole 711 and the ventilation hole 713 in sequence. When the gas passes through the dust blocking hole 711, it is blown away. Dust is trapped at the bottom of the arc-shaped baffle 710. Simultaneously, the gas blows the dust from the bottom of the arc-shaped baffle 710 into the side arc hole 708 on the side arc plate 707, and then out through the side arc hole 708 to the outside of the annular square shell 1. The gas is guided to the middle part of the stainless steel strip for blowing and dust removal through the arc-shaped design of the side arc plate 707. The gas blown to the top surface of the stainless steel strip continues to blow from the bottom towards the arc-shaped baffle 710. The gas blows the inner arc-shaped deflector 712 towards the arc-shaped baffle 710 to scrape away dust. After cleaning, the air pump 705 is turned off, and the electric heating plate 701 is started to heat the stainless steel strip at the bottom of the annular square shell 1. After heating to a certain temperature and maintaining it for a period of time, the cooling strip 706 is fully inserted into the bottom square shell 703, and the air pump is started. Gas is sprayed onto the bottom square shell 703. The gas is cooled by the cooling bar 706 and then blown onto the surface of the stainless steel strip for further cooling, thus completing the annealing process. The powerful jet force propels the square scraper 7042 to slide upwards inside the bottom square shell 703, scraping away impurities. Simultaneously, gas is blown from the bottom center of the square scraper 7042 to both sides. The gas blown to both sides is discharged out through the exhaust port 702 via the curved ring plate 7043. At the same time, the gas blows the inclined connecting plate 7044 inside the curved ring plate 7043, causing the curved ring plate 7043 to rotate around the central block 7045. The inclined connecting plate 7044, through its tilted setting and rotation, diffuses the air upwards towards the square scraper 7042.Simultaneously, as the inclined connecting plate 7044 rotates, the upward movement of the square scraper 7042 causes the top upper brush 7046 to move as well. When the upper brush 7046 moves to contact the heating plate 701, it rotates and cleans the vent 702. As the square scraper 7042 moves upward, it pushes the plastic ring 7047 against the bottom of the heating plate 701, causing it to press and expand outwards. As the plastic ring 7047 expands outwards, it wipes and cleans the bottom of the heating plate 701. Simultaneously, as the plastic ring 7047 opens outwards, the built-in brush 7048 on the inner wall cleans the vent 702.

[0031] In operation, the stainless steel strip 3 is placed between the two inner push plates 206. The long pull rod 202 is rotated from one side of the side corner plate 201, passing through the side corner plate 201 via a threaded connection and then through the stainless steel strip 3. Simultaneously, the stainless steel strip 3 is pulled open to the other side of the annular square shell 1 and fixed to the handle 4. Rotating the handle 4 shell unwinds the stainless steel strip 3. After passing through the stainless steel strip 3, the long pull rod 202 passes through the other side corner plate 201 again via a threaded connection, facilitating the installation and removal of the stainless steel strip 3. When the long pull rod 202 passes through the other side corner plate 201, it pushes the stop block 204. When the long pull rod 202 and the other side corner plate 201 are no longer threaded, rotating the long pull rod 202 will prevent it from moving, and the return spring 203 will simultaneously... The pull-back force pulls back the stop block 204, which resists the long pull rod 202. At the same time, the inner push spring 205 pushes the inner push plate 206 to push the stainless steel coil 3 through its extension force. The two inner push plates 206 push the stainless steel coil 3 to the middle position. When the inner push plates 206 push the stainless steel coil 3, the clamping piece 208 on one side of the inner push plate 206 will get into the gap of the stainless steel coil 3 and separate the stainless steel coil 3. At the same time, the tightening ring 207 is opened and fitted onto the stainless steel coil 3. The tightening ring 207 tightens the stainless steel coil 3 inward. When the stainless steel strip slides past the bottom of the annular square shell 1, the downward pressure spring 602 pushes the downward push plate 603 to resist the stainless steel coil 3 through its extension force. At the same time, the upward thread at the top of the downward push plate 603... Rod 604, passing through side plate 601, limits the downward push plate 603. Simultaneously, as the stainless steel strip slides, it contacts the V-shaped plastic plate 605 on one side of the downward push plate 603. Side brushes 606 on the V-shaped plastic plate 605 clean the sliding stainless steel strip. The V-shaped plastic plate 605 accumulates the cleaned dust on both sides, and as the dust accumulates, combined with the sliding force of the stainless steel strip, the dust is pushed to both sides of the V-shaped plastic plate 605 for discharge. Before annealing, air pump 705 is activated to spray air into the bottom square shell 703. The gas exits from the bottom square shell 703 through exhaust port 702, blowing dust off the bottom of the stainless steel strip. After exiting through exhaust port 702, the gas passes through dust-blocking hole 711 and ventilation hole 713 in sequence. Dust blown through dust holes 711 is blocked at the bottom of the arc-shaped baffle 710. Simultaneously, the gas blows the dust from the bottom of the arc-shaped baffle 710 into the side arc holes 708 on the side arc plate 707, and then out through the side arc holes 708 to the outside of the annular square shell 1. The gas is guided to the middle part of the stainless steel strip for cleaning through the arc shape of the side arc plate 707. The gas blown to the top surface of the stainless steel strip continues to blow from the bottom towards the arc-shaped baffle 710. The gas blows the inner arc-shaped deflector 712 towards the arc-shaped baffle 710 to scrape away dust. After cleaning, the air pump 705 is turned off, and the electric heating plate 701 is started to heat the stainless steel strip at the bottom of the annular square shell 1. After heating to a certain temperature and maintaining it for a period of time, the cooling strip 706 is fully inserted into the bottom square shell 703.The air pump 705 is activated to spray air onto the bottom square shell 703. The air is cooled by the cooling bar 706 and then blown onto the surface of the stainless steel strip for further cooling, thus completing the annealing process. The powerful jet force propels the square scraper 7042 to slide upwards inside the bottom square shell 703, scraping away impurities. Simultaneously, air is blown from the bottom center of the square scraper 7042 to both sides. The air blown to both sides is discharged through the curved ring plate 7043 to the exhaust port 702. At the same time, the air blows the inclined connecting plate 7044 inside the curved ring plate 7043, causing the curved ring plate 7043 to rotate around the central block 7045. The inclined plate 7044, in conjunction with its rotation, diffuses air upwards towards the square scraper 7042. Simultaneously, as the inclined plate 7044 rotates, the upward movement of the square scraper 7042 moves the top upper brush 7046 along with it. When the upper brush 7046 contacts the heating plate 701, it rotates and cleans the exhaust hole 702. As the square scraper 7042 moves upwards, it pushes the plastic ring 7047 against the bottom of the heating plate 701, causing it to press and expand outwards. As the plastic ring 7047 expands outwards, it wipes and cleans the bottom of the heating plate 701. Simultaneously, the built-in brush 7048 on the inner wall cleans the exhaust hole 702.
