Description

Technical Field

[0001] This invention relates to the field of silicon steel annealing correction technology, and in particular to a silicon steel annealing furnace correction device. Background Technology

[0002] Currently, annealing furnaces are present in continuous heat treatment lines for silicon steel in the metallurgical industry. For medium and high grade non-oriented silicon steel and oriented silicon steel, horizontal annealing furnaces are used in the heat treatment lines. Because silicon steel requires low and stable annealing tension, and the annealing furnace is relatively long, the strip tension is low, and the strip is prone to deviation. Therefore, a correction roller is arranged at the outlet of the annealing furnace to correct its deviation in order to produce products with stable quality. Existing silicon steel heat treatment lines usually set correction rollers and tension gauge rollers in sequence after the annealing furnace.

[0003] A patent with publication number CN118497483A discloses a tension control device for an annealing furnace of silicon steel and a silicon steel annealing furnace production system. This tension control device for an annealing furnace of silicon steel includes a pre-furnace tension roller and a pre-furnace straightening roller arranged sequentially on the inlet side of the annealing furnace, and a post-furnace straightening roller and a post-furnace tension roller arranged sequentially on the outlet side of the annealing furnace. The pre-furnace straightening roller and the post-furnace straightening roller are located on the inlet and outlet sides of the annealing furnace, respectively. A tension meter is integrated into the post-furnace straightening roller by placing the tension meter directly below the roller bearing seat. Because the tension meter is directly placed below the roller bearing seat of the pre-furnace straightening roller, and the straightening roller integrates the function of a tension meter roller, compared to the existing tension meter rollers that are separately placed behind the straightening roller, the tension meter is much closer to the annealing furnace, resulting in more accurate tension measurement. This facilitates stable control of the tension of the silicon steel, thereby improving the finished product quality of the silicon steel strip.

[0004] In the production of silicon steel, to improve the problem of deviation, the transmission method is to manually adjust the perpendicularity of the free idler roller at the annealing furnace outlet and the running direction of the strip to guide and correct the deviation. The effect is relatively obvious. However, due to the influence of many factors such as strip shape and tension fluctuation, manual adjustment is required repeatedly, which is inefficient and labor-intensive. Moreover, when the output and receiving ends of the silicon steel change speed during rapid movement, the two ends will exert extrusion force on the silicon steel, causing the middle part of the silicon steel to form a raised state. The raised silicon steel will expand to both sides, thus deviating from its original position and causing deviation. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem in the prior art that when the output end and receiving end of silicon steel change in speed, the silicon steel in the taut state changes to the relaxed state. In the relaxed state, the silicon steel in the two ends will exert extrusion force on the silicon steel while the length remains unchanged, thereby increasing the length of the silicon steel and causing the middle position of the silicon steel to be raised. The silicon steel in the raised state will expand to both sides, thereby deviating from its original position and causing deviation.

[0006] To solve the above-mentioned technical problems, the present invention provides a silicon steel annealing furnace correction device, including a foundation platform and a support frame fixedly installed on the outer surface of the top of the foundation platform. The support steel frame is fixedly installed on the top surface of the foundation platform and is positioned on the back of the support frame. Silicon steel is movably sleeved on the inner wall of the support frame. A support base is provided on the inner wall of the support frame. A rotating shaft is movably sleeved on the top surface of the support base at the middle position. The inner wall of the silicon steel slides against the outer surface of the rotating shaft. A fixing block is provided on the top surface of the support base. V-shaped hinge plates are fixedly connected to both ends of the fixing block. Elastic push wires are fixedly connected to the inner wall of the V-shaped hinge plates. An auxiliary arc plate is fixedly connected to the other side surface of the V-shaped hinge plates. The inner walls of the fixing block and the auxiliary arc plate are movably against the outer surface of the silicon steel.

[0007] In one embodiment of the present invention, a fixing pin is fixedly installed on the top surface of the support base and at the two side edges, a movable support is provided on the top surface of the fixing pin, and a movable support fixing pin is movably sleeved on the inner side wall of the movable support.

[0008] In one embodiment of the present invention, a furnace roller support is fixedly connected to the other end of the movable support fixing pin. The furnace roller support is positioned at the top edge of the rotating shaft and the support base. A support roller is provided on the top surface of the fixing pin and at one side edge of the movable support fixing pin.

[0009] In one embodiment of the present invention, damping telescopic rods are symmetrically fixedly connected to the inner walls on both sides of the support base, and elastic wires are movably sleeved on the outer surface of the damping telescopic rods.

[0010] In one embodiment of the present invention, the other end of the damping telescopic rod is fixedly connected to the outer surface of the fixing block, and the two ends of the elastic wire are respectively movably overlapped on the outer surface of the fixing pin and the fixing block.

[0011] In one embodiment of the present invention, wear-resistant paddles are provided on the inner wall surfaces of the fixing block and the auxiliary arc plate, and are movably attached to the outer surface of the silicon steel. A fan is fixedly installed on the outer surface of the auxiliary arc plate. A cavity is provided between the wear-resistant paddles, the fixing block, and the auxiliary arc plate, and the output end of the fan extends into the cavity.

[0012] In one embodiment of the present invention, an elastic buffer wire is fixedly connected to the top inner wall of the furnace roller support, a flexible plate is fixedly connected to the inner walls of both sides of the furnace roller support, and a wear-resistant roller is fixedly connected to the bottom surface of the flexible plate.

[0013] In one embodiment of the present invention, the bottom surface of the wear-resistant roller is movably overlapped with the top surface of the silicon steel, and the other end of the elastic buffer wire is fixedly connected to the top outer surface of the flexible plate.

[0014] In one embodiment of the present invention, a motor is fixedly installed on the top inner wall of the supporting steel frame, a threaded rod is fixedly connected to the output end of the motor, a fixed base is movably overlapped on the inner surface of the supporting steel frame, and the outer surfaces of the threaded rod and the limiting auxiliary rod are disposed on the outer surface of the fixed base.

[0015] In one embodiment of the present invention, a hydraulic rod is fixedly installed on the inner side wall of the top of the fixed base, and an arc-shaped extrusion plate is fixedly connected to the output end of the hydraulic rod and movably overlaps the top surface of the fixed base. The inner side wall of the arc-shaped extrusion plate movably overlaps the outer side surface of the auxiliary arc plate.

[0016] The technical solution of the present invention has the following advantages compared with the prior art:

[0017] The present invention discloses a silicon steel annealing furnace correction device. When the silicon steel extends out of the annealing furnace, it is constrained by a rotating shaft on the top surface of the support base, causing the silicon steel to rotate around the rotating shaft. When the output end and receiving end of the silicon steel change speed, causing positional deviation and deviation, the correction device rotates freely according to the deviation position and amount of the strip. The strip forms an angle with the roller surface of the correction device, resulting in a deviation in perpendicularity between the roller surface of the correction device and the strip. Along the running direction of the strip, one side moves forward and the other backward, with the deviation point of the strip in the forward position, causing the strip to be corrected backward until the strip forms a 90° angle with the roller surface of the correction device, thus stopping the deviation.

[0018] The present invention discloses a silicon steel annealing furnace correction device. When the silicon steel rotates on the surface of the rotating shaft, the fixing block on one end of the damping telescopic rod and the surface of the auxiliary arc plate are attached to the surface of the silicon steel. The inner wall of the silicon steel is tightly attached to the surface of the rotating shaft by the extrusion of the auxiliary arc plate. The remaining position of the silicon steel will form an angle under the extrusion of the auxiliary arc plate. The angle will create tension on the surface of the silicon steel, so that the overall surface of the silicon steel is always in a relatively tight state. The silicon steel in the tight state will always be in a tensile state, which greatly reduces the effect of the silicon steel deviating from its original position due to changes in tension during transportation, which may cause stagnation or relaxation in the middle position.

[0019] The present invention discloses a silicon steel annealing furnace correction device. When there is a slight change in the speed of the output end and the receiving end of the silicon steel, the silicon steel will squeeze the auxiliary arc plate, which will then elastically expand on the surface of the V-shaped hinge plate. At this time, the elastic pushing wire on the outer surface of the auxiliary arc plate will continuously provide a squeezing force to the auxiliary arc plate, so that the inner wall of the auxiliary arc plate will always be in contact with the two sides of the silicon steel. This keeps the silicon steel in a squeezed state and in its original position, while the excess raised silicon steel will not shake too much during the movement and transportation, reducing the positional deviation of the silicon steel and achieving the effect of correcting the silicon steel.

[0020] The silicon steel annealing furnace correction device of this invention addresses the issue that when the speed changes excessively between the output and receiving ends of the silicon steel, expansion and accumulation occur in the middle of the silicon steel, causing it to detach from the surface of the rotating shaft. The continuously expanding silicon steel expands outwards. At this point, the elastic wires on the outer surface of the damping telescopic rod buffer the continuously expanding and compressing fixed block, preventing the silicon steel from expanding too much at once, thus avoiding it falling out of the fixed block and support base. Simultaneously, a hydraulic rod pushes the arc-shaped extrusion plate, causing its surface to adhere to the outer surface of the auxiliary arc plate, compressing the surface of the auxiliary arc plate and limiting the expansion of the fixed block and auxiliary arc plate. This reduces the risk of the silicon steel detaching from the fixed block and auxiliary arc plate due to excessive expansion speed, significantly increasing the contact area and range between the fixed block / auxiliary arc plate and the silicon steel.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0034] Please see Figure 1 - Figure 10This invention provides a correction device for a silicon steel annealing furnace, including a base platform 11 and a support frame 12 fixedly installed on the outer surface of the top of the base platform 11. A support steel frame 13 is fixedly installed on the top surface of the base platform 11, and the support steel frame 13 is positioned on the back of the support frame 12. A silicon steel 14 is movably sleeved on the inner wall of the support frame 12. A support base 121 is provided on the inner wall of the support frame 12. A rotating shaft 123 is movably sleeved on the top surface of the support base 121 at the middle position. The inner wall of the silicon steel 14 slides against the outer surface of the rotating shaft 123. On the top surface of the support base 121, a fixing block a3 is provided. V-shaped hinge plates a4 are fixedly connected to both ends of the fixing block a3. Elastic pushing wires a5 are fixedly connected to the inner wall of the V-shaped hinge plates a4. An auxiliary arc plate a6 is fixedly connected to the other side surface of the V-shaped hinge plates a4. The inner walls of the fixing block a3 and the auxiliary arc plate a6 are movably fitted against the outer surface of the silicon steel 14. Fixing pins 122 are fixedly installed on the top surface of the support base 121 at both edges. Movable supports 125 are provided on the top surface of the fixing pins 122. A movable support fixing pin 126 is movably sleeved on the inner wall of 5. A furnace roller support 124 is fixedly connected to the other end of the movable support fixing pin 126. The furnace roller support 124 is positioned at the top edge of the rotating shaft 123 and the support base 121. A roller 127 is provided on the top surface of the fixing pin 122 and at one edge of the movable support fixing pin 126. Damping telescopic rods a1 are symmetrically fixedly connected to the inner walls on both sides of the support base 121. An elastic wire a2 is movably sleeved on the outer surface of the damping telescopic rod a1. The top inner wall of the support steel frame 13... A motor 132 is fixedly mounted on the upper part of the support frame 13. A threaded rod 133 is fixedly connected to the output end of the motor 132. A fixed base 131 is movably overlapped on the inner surface of the support frame 13. The outer surfaces of the threaded rod 133 and the limiting auxiliary rod 134 are set on the outer surface of the fixed base 131. A hydraulic rod 135 is fixedly mounted on the inner wall of the top of the fixed base 131. An arc-shaped extrusion plate 136 is fixedly connected to the output end of the hydraulic rod 135 and movably overlapped on the top surface of the fixed base 131. The inner wall of the arc-shaped extrusion plate 136 movably overlaps on the outer surface of the auxiliary arc plate a6.

[0035] After the silicon steel 14 extends out of the annealing furnace, the surface of the silicon steel 14 is limited by the rotating shaft 123 on the top surface of the support base 121, and the silicon steel 14 rotates around the surface of the rotating shaft 123. When the output end and receiving end of the silicon steel 14 change in speed, causing the silicon steel 14 to deviate in position and run off course, the correction device rotates freely according to the deviation position and deviation amount of the strip. The strip and the roller surface of the correction device form an angle, and then the roller surface of the correction device deviates from the perpendicularity of the strip. Along the running direction of the strip, one side is forward and the other side is backward. The deviation point of the strip is in the forward position, causing the strip to be corrected to the backward position until the strip and the roller surface of the correction device form a 90° angle and stop the deviation.

[0036] When silicon steel 14 rotates on the surface of rotating shaft 123, the fixed block a3 on one end of damping telescopic rod a1 and the surface of auxiliary arc plate a6 are attached to the surface of silicon steel 14. The inner wall of silicon steel 14 is tightly attached to the surface of rotating shaft 123 by the compression of auxiliary arc plate a6. The remaining position of silicon steel 14 will form an angle under the compression of auxiliary arc plate a6. The angle will create tension on the surface of silicon steel 14, so that the overall surface of silicon steel 14 is always in a relatively tight state. The silicon steel 14 in the tight state will always be in a tensile state, which greatly reduces the effect of silicon steel 14 deviating from its original position due to changes in tension during transportation.

[0037] When there is a slight change in the speed of the output end and the receiving end of the silicon steel 14, the silicon steel 14 will squeeze the auxiliary arc plate a6, which will cause the auxiliary arc plate a6 to expand elastically on the surface of the V-shaped hinge plate a4. At this time, the elastic pushing wire a5 on the outer surface of the auxiliary arc plate a6 will continuously provide a squeezing force to the auxiliary arc plate a6, so that the inner wall of the auxiliary arc plate a6 will always be in contact with the two sides of the silicon steel 14, so that the silicon steel 14 will always be in a squeezed state and remain in its original position. The excess raised silicon steel 14 will not shake too much during the movement and transportation, reducing the positional deviation of the silicon steel 14 and achieving the effect of correcting the deviation of the silicon steel 14.

[0038] When the speed changes too much at the output and receiving ends of the silicon steel 14, expansion and accumulation occur in the middle of the silicon steel 14. The silicon steel 14 will then detach from the surface of the rotating shaft 123. The continuously expanding silicon steel 14 will expand outwards. At this time, the elastic wire a2 on the outer surface of the damping telescopic rod a1 buffers the continuously expanding and compressing fixed block a3, preventing the silicon steel 14 from expanding too much at once, thus avoiding it from falling out of the fixed block a3 and the support base 121. Simultaneously, the hydraulic rod 135 pushes the arc-shaped extrusion plate 136, causing its surface to adhere to the outer surface of the auxiliary arc plate a6, compressing the surface of the auxiliary arc plate a6 and limiting the expansion of the fixed block a3 and the auxiliary arc plate a6. This reduces the risk of the silicon steel 14 detaching from the fixed block a3 and the auxiliary arc plate a6 due to excessive expansion speed, significantly increasing the contact area and range between the fixed block a3, the auxiliary arc plate a6, and the silicon steel 14.

[0039] Furthermore, such as Figure 1 - Figure 2 and Figure 4 - Figure 10 As shown, the other end of the damping telescopic rod a1 is fixedly connected to the outer surface of the fixed block a3, and the two ends of the elastic wire a2 are respectively movably overlapped on the outer surface of the fixed pin 122 and the fixed block a3. Wear-resistant paddles a7 are provided on the inner wall of the fixed block a3 and the auxiliary arc plate a6, which are movably attached to the outer surface of the silicon steel 14. A fan a8 is fixedly installed on the outer surface of the auxiliary arc plate a6. A cavity a9 is provided between the wear-resistant paddles a7, the fixed block a3, and the auxiliary arc plate a6. The output end of the blower a8 extends into the cavity a9. An elastic buffer wire 1241 is fixedly connected to the inner top wall of the furnace roller support 124. A flexible plate 1242 is fixedly connected to the inner walls on both sides of the furnace roller support 124. A wear-resistant roller 1243 is fixedly connected to the bottom surface of the flexible plate 1242. The bottom surface of the wear-resistant roller 1243 is movably overlapped on the top surface of the silicon steel 14. The other end of the elastic buffer wire 1241 is fixedly connected to the outer top surface of the flexible plate 1242.

[0040] When the silicon steel 14 slides on the surface of the fixed block a3 and the auxiliary arc plate a6, the wear-resistant pawl a7 comes into contact with the surface of the silicon steel 14. At this time, the fan a8 blows air into the cavity a9. When the cold air hits the back of the wear-resistant pawl a7, the rapidly flowing gas will remove the residual heat on the back of the wear-resistant pawl a7, which can greatly prevent the surface temperature of the wear-resistant pawl a7 from becoming too high and reducing its service life.

[0041] Working principle: After the silicon steel 14 extends out of the annealing furnace, it is constrained by the rotating shaft 123 on the top surface of the support base 121, and the silicon steel 14 rotates around the surface of the rotating shaft 123. When the output end and receiving end of the silicon steel 14 change in speed, causing the silicon steel 14 to deviate in position and run off course, the correction device rotates freely according to the deviation position and deviation amount of the strip. The strip forms an angle with the roller surface of the correction device, and thus the roller surface of the correction device deviates from the strip in perpendicularity. Along the running direction of the strip, one side moves forward and the other side moves backward. The deviation point of the strip is in the forward position, causing the strip to move backward to correct the deviation until the strip forms a 90° angle with the roller surface of the correction device and stops the deviation.

[0042] When the silicon steel 14 rotates on the surface of the rotating shaft 123, the fixed block a3 at one end of the damping telescopic rod a1 and the surface of the auxiliary arc plate a6 adhere to the surface of the silicon steel 14. The compression of the auxiliary arc plate a6 further ensures that the inner wall of the silicon steel 14 is tightly adhered to the surface of the rotating shaft 123. The remaining positions of the silicon steel 14 form an angle under the compression of the auxiliary arc plate a6, creating tension on the surface of the silicon steel 14. This keeps the overall surface of the silicon steel 14 in a relatively taut state. This taut state significantly reduces the risk of the silicon steel 14 shifting from its original position during transport due to changes in tension, which could cause stagnation or relaxation in the middle.

[0043] When there is a slight change in the speed of the output end and the receiving end of the silicon steel 14, the silicon steel 14 will squeeze the auxiliary arc plate a6, which will cause the auxiliary arc plate a6 to expand elastically on the surface of the V-shaped hinge plate a4. At this time, the elastic pushing wire a5 on the outer surface of the auxiliary arc plate a6 will continuously provide a squeezing force to the auxiliary arc plate a6, so that the inner wall of the auxiliary arc plate a6 will always be in contact with the two sides of the silicon steel 14, so that the silicon steel 14 will always be in a squeezed state and remain in its original position. The excess raised silicon steel 14 will not shake too much during the movement and transportation, reducing the positional deviation of the silicon steel 14 and achieving the effect of correcting the deviation of the silicon steel 14.

[0044] When the speed changes too much at the output and receiving ends of the silicon steel 14, expansion and accumulation occur in the middle of the silicon steel 14. The silicon steel 14 will then detach from the surface of the rotating shaft 123. The continuously expanding silicon steel 14 will expand outwards. At this time, the elastic wire a2 on the outer surface of the damping telescopic rod a1 buffers the continuously expanding and compressing fixed block a3, preventing the silicon steel 14 from expanding too much at once, thus avoiding it from falling out of the fixed block a3 and the support base 121. Simultaneously, the hydraulic rod 135 pushes the arc-shaped extrusion plate 136, causing its surface to adhere to the outer surface of the auxiliary arc plate a6, compressing the surface of the auxiliary arc plate a6 and limiting the expansion of the fixed block a3 and the auxiliary arc plate a6. This reduces the risk of the silicon steel 14 detaching from the fixed block a3 and the auxiliary arc plate a6 due to excessive expansion speed, significantly increasing the contact area and range between the fixed block a3, the auxiliary arc plate a6, and the silicon steel 14.

[0045] Obviously, the above embodiments are merely illustrative examples for clarity and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
