Description

Technical Field

[0001] This invention application relates to the technical field of hot rolling of steel, and particularly to a hot rolling device for automatic production of steel. Background Art

[0002] Hot rolling is an important process in the steel production process. By plastically deforming the steel billet through rollers at high temperature, steel with the desired shape and size can be obtained. Currently, it is widely used in the production of steel, profiles, plates, etc. It has high production efficiency and good product quality, and is an important foundation of the modern steel industry.

[0003] However, there are many deficiencies in the traditional hot rolling process. For example, an oxide layer generally forms on the surface of the hot-rolled steel. If the sample layer is not processed in time, the oxide layer will make the surface of the steel rough and difficult to process, reducing the surface quality. At the same time, it will reduce the corrosion resistance and wear resistance of the steel, affecting the product life.

[0004] Therefore, in order to improve the quality and service life of steel, the surface of the steel needs to be treated. For example, an automatic hot rolling device for steel production with the publication number CN115870341B efficiently removes the scale on the surface of the steel plate through multiple high-pressure air guns. At the same time, by using the bottom fixed roller, the top hot rolling roller and the rotating mechanism, it ensures that the steel plate is evenly rolled in the hot rolling cavity. Finally, the lifting action of the steel plate is realized through the lifting mechanism and the closing plate, and combined with the cleaning plate and the limiting parts, it further guarantees the quality and efficiency of the steel plate rolling.

[0005] However, there are still some defects in the above-mentioned prior art during the hot pressing of steel: 1. The above patent application only blows the scale on the surface of the steel plate through high-pressure air guns. Due to the strong adhesion of the scale, it is difficult for the high-pressure air guns to completely remove the bottom layer of the scale. Therefore, there is a possibility that the scale cannot be completely removed by this method, resulting in the remaining scale affecting the subsequent surface treatment.

[0006] 2. Since the hot-rolled steel plate becomes thinner, the above-mentioned prior art does not properly support the steel plate before and after hot rolling during the hot rolling process, which will cause a height difference on both sides of the top hot rolling roller of the steel plate, resulting in deformation of the steel plate. And because the hot-rolled steel plate has good flexibility and is more likely to bend, it further exacerbates the problem of the decline in the surface flatness of the steel plate.

[0007] Based on this, under the statement of the above viewpoints, there is still room for improvement in the prior art's method of hot rolling steel. Summary of the Invention

DETAILED DESCRIPTION

[0044] The following is combined with Figures 1 to 12 This application is described in further detail.

[0045] The embodiment of the present application discloses an automated hot rolling equipment for steel production, which ensures that the steel will not bend before and after hot rolling, and can effectively remove the oxide layer on the surface of the steel.

[0046] Embodiment 1:

[0047] Reference Figure 1 and Figure 2 A hot rolling equipment for automated steel production includes symmetrically arranged horizontal frames 1, each of which is equipped with a corresponding vertical frame 2, and a hot rolling mechanism 3 and a conveying mechanism 4 are installed on the two vertical frames 2.

[0048] Reference Figure 2 and Figure 3 The hot rolling mechanism 3 includes: hot rolling rollers 31, which are symmetrically arranged along the height direction of the vertical frame 2.

[0049] The arc-shaped plate 32 is disposed on the opposite side of the vertical frame 2 and corresponds to the two ends of the hot rolling roller 31 one by one.

[0050] The sliding block 33 is slidably arranged inside the arc-shaped plate 32 , and both ends of the hot rolling roller 31 are mounted on the corresponding sliding blocks 33 through bearings.

[0051] The moving block can drive the hot rolling roll 31 to move along the arc plate 32. Furthermore, the distance between the two hot rolling rolls 31 is adjustable. Thus, the cooperation between the two hot rolling rolls 31 and the arc plate 32 can roll steel into steel plates with different thicknesses, with a wider range of applicability.

[0052] Referring to Figure 3 , the conveying mechanism 4 includes: conveying frames 41, two of which are provided and correspond to the vertical frames 2 one by one. They are slidably arranged along the height direction of the vertical frames 2 and move synchronously with the sliding blocks 33.

[0053] Conveying rollers 42, a plurality of which are evenly arranged along the length direction of the conveying frames 41 and are installed between the conveying frames 41 through bearings.

[0054] The conveying frames 41 drive the conveying rollers 42 to move synchronously, which can ensure that no matter what thickness the hot rolling rolls 31 roll the steel into, the positions of the hot rolling rolls 31 and the conveying rollers 42 always remain consistent, avoiding the possibility that the rolled steel plate bends on both sides of the hot rolling rolls 31 due to the height difference between the hot rolling rolls 31 and the conveying rollers 42, so as to ensure the flatness of the steel plate after rolling.

[0055] Rotating rollers 43 for grinding the surface of the steel plate are symmetrically arranged along the height direction between the conveying frames 41 (refer to Figure 9 and Figure 10 ).

[0056] During the rotation of the rotating rollers 43, the surface of the steel can be subjected to friction grinding treatment to ensure that the oxide layer on the surface of the steel can be treated more thoroughly, avoiding the possibility that the oxide layer remains on the surface of the steel after rolling, and reducing the influence of the oxide layer on the surface of the steel on the flatness of the surface of the rolled steel plate.

[0057] Referring to Figure 4 , a fixed frame 21 is installed on the vertical frame 2. A vertical frame 22 is installed on the fixed frame 21. A linkage rod 23 that cooperates with the corresponding side sliding block 33 is slidably arranged through the vertical frame 22 along its height direction. A plurality of linkage blocks 24 are arranged along the length direction of the linkage rod 23. One end of the linkage block 24 far from the corresponding linkage rod 23 is connected to the conveying frame 41 on the same side.

[0058] According to the required processing thickness of the steel, first, the existing drive (electric slider or cylinder) drives the slider 33 to slide along the arc plate 32 for a certain distance. At this time, the sliders 33 move towards each other and move a certain distance in the height direction of the vertical frame 2, changing the distance between the two hot rolling rolls 31. During the movement of the slider 33 near the bottom of the vertical frame 2, the linkage rod 23 is driven to move synchronously. During the movement of the linkage rod 23, the conveying frame 41 is driven to move synchronously through the linkage block 24. At this time, the conveying rolls 42 move synchronously, thereby ensuring that the positions of the hot rolling rolls 31 and the conveying rolls 42 always remain consistent, avoiding the possibility that the rolled steel plate bends on both sides of the hot rolling rolls 31 due to the height difference between the hot rolling rolls 31 and the conveying rolls 42, and ensuring the flatness of the steel plate after rolling.

[0059] Since the thickness of the steel plate changes before and after rolling, taking the vertical frame 2 as the boundary, the height of the conveying roll 42 on the side close to the rotating roll 43 is slightly lower than the height of the hot rolling roll 31 near the bottom of the vertical frame 2. This can ensure that the steel can smoothly enter between the hot rolling rolls 31 while reducing the degree of deformation of the steel between the hot rolling rolls 31 and the corresponding conveying rolls 42, and can support and convey the steel before rolling, avoiding the possibility that the steel deforms before hot rolling.

[0060] The height of the conveying roll 42 on the side far from the rotating roll 43 is the same as the height of the hot rolling roll 31 near the bottom of the vertical frame 2. This facilitates the conveying and support of the rolled steel plate, reducing the possibility that the rolled steel plate bends on both sides of the hot rolling rolls 31 due to the height difference between the corresponding hot rolling rolls 31 and the conveying rolls 42, and improving the flatness of the steel plate rolling.

[0061] Looking back Figure 2 On the slider 33, a limit protrusion 331 is provided. A limit rod 332 for limiting and locking the slider 33 is slidably penetrated through the limit protrusion 331. A plurality of limit holes 333 matched with the limit rod 332 are uniformly arranged along the circumferential direction of the arc plate 32.

[0062] At the starting position, the limit rod 332 is not inserted into the limit hole 333, and the displacement of each movement of the slider 33 is the distance between two adjacent limit holes 333, so as to ensure that for each displacement of the slider 33, there is a corresponding limit hole 333 cooperating with the limit rod 332, thereby ensuring that the slider 33 can be relatively fixed with the arc plate 32. Specifically, when the slider 33 moves to the corresponding height, at this time, the limit rod 332 is inserted into the corresponding limit hole 333. At this time, the limit rod 332 fixes the slider 33 on the arc plate 32, so that the slider 33 keeps the hot rolling roll 31 in a fixed state through the limit rod 332.

[0063] Referring to Figure 5, in order to limit the conveying rack 41, the locking plate 29 designed by the present invention can fix the conveying rack 41 on the vertical rack 2. Specifically, a support connecting rack 25 is commonly installed on the vertical rack 2. A double-acting cylinder two 26 is installed in the middle of the support connecting rack 25 through a cylinder seat. A horizontal round bar 27 is installed on the telescopic end of the double-acting cylinder two 26. A vertical connecting plate 28 is installed at one end of the horizontal round bar 27 away from the double-acting cylinder two 26. A locking plate 29 for locking and limiting the conveying rack 41 is installed on one side of the vertical connecting plate 28 close to the corresponding side vertical rack 2. And the locking plate 29 is slidably arranged on the corresponding side vertical rack 2 and abuts against the conveying rack 41.

[0064] When the conveying rack 41 moves to the specified height, the double-acting cylinder two 26 is started at this time. During the movement of the telescopic end of the double-acting cylinder two 26, the vertical connecting plate 28 is driven to move towards each other through the horizontal round bar 27. During the movement of the vertical connecting plate 28 towards each other, the locking plate 29 is driven to lock the conveying rack 41, so that the friction between the conveying rack 41 and the vertical rack 2 increases. Furthermore, the conveying rack 41 can be fixed on the vertical rack 2, reducing the possibility of the conveying rack 41 shaking.

[0065] Refer to Figure 7 , in order to improve the stability of both ends of the conveying rack 41, the support block 11 and the support connecting block 12 provided by the present invention can cooperate with each other to support both ends of the conveying rack 41. Specifically, support blocks 11 are symmetrically arranged along the length direction of the horizontal machine rack 1. A plurality of support connecting blocks 12 that support the conveying rack 41 are evenly arranged on the support blocks 11 along the height direction thereof.

[0066] During specific operation, when the conveying rack 41 moves to the specified height and is locked by the locking plate 29, an appropriate number of support connecting blocks 12 are placed on the support blocks 11 at this time. At this time, the support blocks 11 and the support connecting blocks 12 cooperate with each other to support both ends of the conveying rack 41, so as to ensure the stability of the conveying rack 41 during the hot rolling process.

[0067] Refer to Figure 6 , in order to ensure that the steel does not slide relatively during the conveying process, the alignment plate 54 designed by the present invention can align and limit the steel during the conveying process, so that the steel always moves towards the hot rolling roll 31 along the length direction of the conveying rack 41. Specifically, a limiting assembly 5 is commonly installed between the conveying racks 41, including: a support frame 51, which is arranged between the two conveying racks 41 and both ends of the support frame 51 are respectively installed on the corresponding side conveying racks 41.

[0068] A double-acting cylinder one 52, which is installed in the middle of the support frame 51 through a cylinder seat.

[0069] Linking plates 53, which are symmetrically arranged along the length direction of the support frame 51 and are slidably arranged on the support frame 51. The two telescopic ends of the double-acting cylinder one 52 are respectively connected to the corresponding side linking plates 53.

[0070] A plurality of alignment plates 54 are evenly arranged along the length direction of the linkage plate 53 , and each alignment plate 54 is located between adjacent conveying rollers 42 .

[0071] During specific operation, the conveying roller 42 is driven to rotate by an external driving force, and the double-axis cylinder 52 is started during the process of the conveying roller 42 transporting steel. The telescopic end of the double-axis cylinder 52 drives the linkage plate 53 to slide on the support frame 51 during the reciprocating movement of the conveying roller 42 in the length direction. The linkage plate 53 synchronously drives the alignment plate 54 to move during the reciprocating movement. During the movement of the alignment plate 54, the steel in the moving process can be continuously limited to prevent the steel from deviating on the conveying roller 42 and affecting its transportation and hot rolling effects.

[0072] Reference Figure 8 and Figure 9 When the steel enters the through groove, the steel is located between the two rotating rollers 43. At this time, the rotating rollers 43 can perform friction and grinding treatment on the steel during the steel conveying process to remove the oxide layer on the surface of the steel. Specifically, the conveying frame 41 is provided with a horizontal plate 411 that reciprocates along the length direction of the conveying frame 41 and is located between the limiting assembly 5 and the hot rolling roller 31. The horizontal plate 411 is provided with a through groove for passing the steel plate. The rotating rollers 43 extend along the length direction of the through groove and are symmetrically arranged along the height direction of the through groove, and are installed on the inner wall of the through groove through bearings.

[0073] During specific operation, when the steel passes through the through groove, the horizontal plate 411 moves back and forth. During the movement of the horizontal plate 411, the rotating roller 43 can be driven to move back and forth. During the reciprocating movement of the rotating roller 43, dynamic friction can be applied to the oxide layers on the upper and lower surfaces of the steel. At this time, the rotating roller 43 is driven to rotate by an external driving force (motor, etc.). During the rotation of the rotating roller 43, dynamic friction can be applied to the surface of the steel plate, and then the stubborn oxide layer on the surface of the steel can be frictionally polished to ensure that the oxide layer can be removed from the surface of the steel.

[0074] Reference Figure 9 and Figure 11 In order to reduce the use of existing drives, the rack plate 414 and the driving gear 413 provided by the present invention cooperate with each other to drive the rotating roller 43 to rotate adaptively. Specifically, the shaft head of the rotating roller 43 passes through the side wall of the horizontal plate 411, and the two ends of the horizontal section are rotatably installed with a linkage shaft 412 through bearings. The driving gear 413 is installed at one end of the linkage shaft 412 away from the horizontal plate 411, and a rack plate 414 meshing with the driving gear 413 is installed on the linkage rod 23 on the corresponding side. The linkage shaft 412 and the shaft head of the rotating roller 43 on the corresponding side are connected through a gear transmission.

[0075] During specific operation, the horizontal plate 411 synchronously drives the driving gear 413 to move through the linkage shaft 412 during the reciprocating movement. During the movement of the driving gear 413, it meshes with the rack plate 414 and synchronously drives the linkage shaft 412 to rotate. During the rotation of the linkage shaft 412, the rotating roller 43 is driven to rotate through the gear transmission, and then the rotating roller 43 can be driven to rotate without external force, and then the rotating roller 43 is driven to rotate without external drive to rub and polish the oxide layer on the surface of the steel.

[0076] Reference Figure 10 A material leakage trough 415 matching the through groove is provided at the bottom of the horizontal plate 411, and a plurality of impurity removal pipes 416 connected to the through groove are provided at the top of the horizontal plate 411 along its length direction. A nozzle 417 for blowing the oxide layer on the top and bottom of the steel plate is also provided inside the through groove.

[0077] The impurity removal pipe 416 is connected to an external vacuum cleaner (not shown in the figure). During operation, gas is pumped into the nozzle 417 through an external air pump (not shown in the figure) in the process of the steel plate passing through the through groove. At this time, the gas forms an airflow through the nozzle 417 and blows to the top and bottom of the steel, thereby blowing the oxide layer rubbed and polished on the surface of the steel. The oxide layer on the surface of the steel is lifted up, and the oxide layer lifted up from the top of the steel is diffused on the top of the through groove. The impurity removal pipe 416 has a pressure difference between the inside and the outside due to the external vacuum cleaner's suction, and the oxide layer diffused on the top of the through groove is adsorbed by the external vacuum cleaner through the impurity removal pipe 416, and the oxide layer diffused on the bottom of the through groove leaks out through the leakage groove 415, and the oxide layer leaked from the leakage groove 415 is collected by the existing collection frame (not shown in the figure).

[0078] Replay Figure 2 A driving roller 311 matching the hot rolling roller 31 is installed between the vertical frames 2 through a bearing, and the driving roller 311 is connected to the corresponding hot rolling roller 31 through a gear transmission method.

[0079] When the steel moves between the hot rolling rollers 31, the driving roller 311 is driven to rotate by an external driving force. During the rotation of the driving roller 311, the hot rolling roller 31 is driven to rotate by a gear transmission. During the rotation of the hot rolling roller 31, the steel can be rolled to obtain a steel plate. The obtained steel plate continues to move along the length direction of the conveying frame 41 through the conveying roller 42 until a formed steel plate is obtained.

[0080] Embodiment 2:

[0081] Reference Figure 12On the basis of the first embodiment, a lifting cylinder 13 is further installed on the horizontal frame 1, and a height sensor is installed on the sliding block 33 near the bottom of the vertical frame 2. The height sensor is electrically connected to the lifting cylinder 13 through a central control component, wherein the central control component includes a central control panel arranged on the horizontal frame 1 and a central control unit arranged inside the central control panel, wherein the central control unit includes a central control module, a cylinder control module electrically connected to the central control module, and a distance sensor module electrically connected to the central control module.

[0082] The cylinder control module is electrically connected to the lifting cylinder 13, and the distance sensor module is electrically connected to the height sensor.

[0083] During specific operation, during the movement of the sliding block 33, the height sensor can measure the moving height of the sliding block 33. At this time, the height sensor transmits the measured data to the distance sensing module, and the distance sensing module processes the data and transmits it to the central control module. The central control module processes the data information and transmits it to the cylinder control module. The cylinder control module processes the data and transmits it to the lifting cylinder 13. At this time, the lifting cylinder 13 is started, and the telescopic end of the lifting cylinder 13 drives the conveying frame 41 on the corresponding side to move the same distance as the moving height of the sliding block 33, thereby making the up and down moving distance of the conveying frame 41 more intelligent.

[0084] Example 3, refer to Figure 11 On the basis of embodiment 1, the shaft head of the conveying roller 42 between the vertical frame 2 and the horizontal plate 411 passes through the corresponding conveying frame 41, and a toggle plate 421 is installed on the shaft head of the conveying roller 42. A downward-opening 匚-shaped frame 422 is arranged between the two ends of the horizontal plate 411 and the conveying frame 41 on the corresponding side. Any vertical section of the 匚-shaped frame 422 is installed on the horizontal plate 411, and the 匚-shaped frame 422 is slidably arranged on the conveying frame 41 on the corresponding side away from the horizontal vertical section, and an elastic telescopic rod 423 for resetting the 匚-shaped frame 422 on the corresponding side is installed on the conveying frame 41, and a linkage frame 424 cooperating with the toggle plate 421 on the same side is installed on the vertical section of the 匚-shaped frame 422 close to the conveying frame 41.

[0085] The elastic telescopic rod 423 is installed on the conveying frame 41, and the telescopic end of the elastic telescopic rod 423 is installed on the corresponding profile frame 422. During specific operation, the corresponding conveying roller 42 drives the toggle plate 421 to rotate during rotation. When the toggle plate 421 rotates and approaches the linkage frame 424, the toggle plate 421 drives the linkage frame 424 to move away from the vertical frame 2. At this time, the linkage frame 424 drives the profile frame 422 to move synchronously during the movement. During the movement of the profile frame 422, the horizontal plate 411 can be driven to move away from the vertical frame 2. At this time, the elastic telescopic rod 423 is stretched. When the toggle plate 421 is disengaged from the linkage frame 424, the elastic telescopic rod 423 is reset. At this time, the profile frame 422 drives the horizontal plate 411 to reset synchronously.

[0086] When the toggle plate 421 contacts the linkage frame 424 again, the above-mentioned action is repeated, and then the profile frame 422 can also drive the horizontal plate 411 to move back and forth.

[0087] The implementation principle of the present invention is:

[0088] (1): According to the required processing thickness of the steel, the existing drive (electric slider or cylinder) is first used to drive the sliding block 33 to slide a certain distance along the arc plate 32. At this time, the sliding blocks 33 move toward each other and move a certain distance in the height direction of the vertical frame 2. The spacing between the two hot rolling rollers 31 changes. During the movement of the sliding block 33 near the bottom of the vertical frame 2, the linkage rod 23 is driven to move synchronously. During the movement of the linkage rod 23, the linkage block 24 is used to synchronously drive the conveying frame 41 to move synchronously. At this time, the conveying roller 42 moves synchronously, thereby ensuring that the positions of the hot rolling roller 31 and the conveying roller 42 are always consistent.

[0089] (2): When the conveying frame 41 moves to the specified height, the double-axis cylinder 26 is started. During the movement of the telescopic end of the double-axis cylinder 26, the horizontal round rod 27 drives the vertical connecting plate 28 to move toward each other. During the movement of the vertical connecting plate 28, the locking plate 29 is driven to lock the conveying frame 41.

[0090] (3): The horizontal plate 411 drives the driving gear 413 to move synchronously through the linkage shaft 412 during the reciprocating movement. The driving gear 413 meshes with the rack plate 414 during the movement to synchronously drive the linkage shaft 412 to rotate. During the rotation of the linkage shaft 412, the rotating roller 43 is driven to rotate through the gear transmission, thereby driving the rotating roller 43 to rotate without external force, thereby driving the rotating roller 43 to rotate without external drive, thereby frictionally grinding the oxide layer on the surface of the steel.

[0091] (4): During the process of the steel plate passing through the inside of the through groove, gas is pumped into the inside of the nozzle 417 by an external air pump (not shown in the figure). At this time, the gas forms an air flow through the nozzle 417 and blows towards the top and bottom of the steel material, thereby being able to blow the oxide layer that rubs and polishes the surface of the steel material. The oxide layer on the surface of the steel material rises. At this time, the oxide layer rising from the top of the steel material fills the top of the through groove. Due to the external vacuum cleaner pumping air, there is an internal and external pressure difference in the impurity removal pipe 416. Therefore, the oxide layer filling the top inside the through groove is adsorbed and processed by the external vacuum cleaner through the impurity removal pipe 416, and the oxide layer filling the bottom inside the through groove leaks out through the material leakage groove 415. The oxide layer leaking out from the material leakage groove 415 is collected by an existing collection box (not shown in the figure).
