Description

Technical Field

[0001] The present invention relates to the technical field of rolling, and more specifically, to an iron laminate rolling device and its usage method. Background Art

[0002] Rolling equipment is the core equipment in metal sheet processing, which realizes the thickness reduction and performance optimization of metal sheets through the combination of high-temperature heating and mechanical pressure. In current technologies, iron laminates are usually rolled using double-roll or multi-roll mills, and steel billets heated to 1000 - 1200 °C are transported between the rolls for reciprocating pressing. And the conical roll design is used to compensate for the thermal expansion effect. During this process, the rolling equipment needs to cooperate with a high-pressure water descaling device to spray the surface of the sheet to remove the high-temperature oxide layer and ensure the surface quality after rolling.

[0003] However, iron laminates are prone to form a dense oxide layer, such as scale, in the high-temperature environment before rolling, and its residue will directly affect the rolling accuracy and the performance of the finished product. In current technologies, although the water spraying step can wash away some scale through high-pressure water flow, due to the uneven temperature distribution of the steel billet, such as rapid cooling at the edges and high temperature in the center, and through retrieval, it can be known that in the patent with the publication number CN112496048A, a rolling equipment is provided, which can adjust the problem of uneven temperature distribution of the metal billet by adding a cooling box.

[0004] However, through further analysis, it is found that its water spraying mechanism is a static design, and the fixed-water-pressure spraying system is difficult to dynamically adapt to the scale peeling requirements of different regions, that is, the water spraying step cannot combine additional peeling structures to serve the subsequent rolling work, resulting in the unremoved scale that may be embedded in the sheet during subsequent rolling, causing a decrease in the interlayer bonding force or local stress concentration, and resulting in defects such as warping and fracture of the finished plate. Summary of the Invention

An electric telescopic rod movably connected to the same-side corner of the outer open U-shaped support plate is hingedly installed on each second hinged base.

[0018] A method for using an iron sheet rolling equipment, comprising the following steps:

[0019] S1: First, two sets of rolling rolls are unfolded through the output end of the roll driving device, and the rolling sheet to be processed is conveyed between the two sets of rolling rolls in cooperation with the rolling sheet conveying base unit, and the outer oxide skin stripping module at the output end is made to approach the rolling sheet to be processed in cooperation with the multi-axis adjustment arm;

[0020] S2: Then, the upper oxide skin stripping unit and the lower oxide skin stripping unit at the output end are controlled by the rolling sheet outer oxide skin stripping module to fit the rolling sheet to be processed, and the reciprocating cycle driving unit is used to drive the stripping mechanism to perform reciprocating cycle stripping on the oxide layer on the surface;

[0021] S3: Finally, while spraying water to strip the outer oxide layer of the rolling roll plate at the roll end through the spray water in the first conduit, the waste water is collected by the lower oxide skin stripping unit and conveyed to the stripping water heat energy circulation module on both sides of the rolling end for heat energy circulation.

[0022] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects:

[0023] (1) By combining the dynamically adapted oxide skin stripping structure with the multi-angle spraying system, the removal efficiency of the oxide layer on the surface of the iron sheet is improved. The problem that the traditional static water spraying mechanism is difficult to cope with the dense oxide layer on the surface of the high-temperature rolling sheet due to the inability to adjust the stripping angle and pressure is solved. During the working process, through the coordinated control of the multi-axis adjustment robotic arm and the bidirectional telescopic rod, the upper and lower stripping units can flexibly adapt to the thickness and position of the sheet, and at the same time, through the combination of the U-shaped spray pipe and the intermittent grinding coating, the dynamic matching of the spray water pressure and the mechanical stripping force is realized. The spray water is not only used to wash away the oxide layer, but also introduced into the cavity disc of the grinding mechanism through the hollow conduit to form a dual effect of cooling and mechanical stripping, effectively solving the problem of the decrease in the interlayer bonding force caused by the oxide skin embedding in the substrate.

[0024] (2) Through the intermittent stripping mechanism, through the cooperation of the wave ring sleeve and the return spring, the periodic telescopic movement of the grinding coating is realized, and the microcracks of the oxide layer are induced to expand by using the difference between the thermal stress and the mechanical stress, and the oxide skin is stripped in stages, which not only avoids substrate damage, but also significantly reduces the oxide residue, and is especially suitable for the processing requirements of high-strain sensitive materials such as iron sheets.

[0025] (3) Through the integrated design of the configured thermal energy cycle and protective gas system, the energy efficiency of the process and the quality of the finished product are improved. The high-temperature spray water after stripping recovers waste heat through the gas guiding cavity cover, heats the inert protective gas, and forms a temperature-controlled gas curtain to cover the rolling area, reducing the risk of secondary oxidation of the metal. Compared with the traditional cold gas curtain, the temperature-controlled gas has a higher density and a more uniform coverage, reducing the thermal stress of the temperature difference between the sheet and the gas during rolling. At the same time, the inclination adjustment function of the rolling plate conveying base cooperates with the outer extended water receiving cover to optimize the directional collection and discharge efficiency of the wastewater, further reducing energy consumption. This design organically combines descaling, rolling, and thermal energy management, comprehensively improving the environmental adaptability and processing stability of the equipment.

[0048] As shown in the figure, in order to clearly implement the structure of the embodiments of the present invention, specific structures and devices are marked in the figure, but this is only for schematic needs and is not intended to limit the present invention to this specific structure, device and environment. According to specific needs, those of ordinary skill in the art can adjust or modify these devices and environments. Detailed implementation manners

[0049] The following will describe in detail an iron laminate rolling equipment and its usage method provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some technicians in the field of well-known technologies, other alternative methods can also be adopted for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0050] As Figures 1 to 11 shown, an embodiment of the present invention provides an iron laminate rolling equipment, including a roll drive device 1. Two sets of rolls 2, one above the other, are arranged at the output end of the roll drive device 1. A rolling plate conveying base unit 3 for continuously conveying a rolling plate between the two sets of rolls 2 for rolling is arranged on the side of the roll drive device 1. A multi-axis adjusting arm 4 is fixedly installed on the side of the roll drive device 1. A rolling plate outer oxide scale peeling module 5 capable of clamping the upper and lower sides of the rolling plate is arranged at the output end of the multi-axis adjusting arm 4;

[0051] The rolling plate outer oxide scale peeling module 5 includes an upper oxide scale peeling unit 53 arranged on the upper side of the rolling plate and a lower oxide scale peeling unit 54 arranged on the lower side of the rolling plate. Both the upper oxide scale peeling unit 53 and the lower oxide scale peeling unit 54 include a reciprocating cycle driving unit 7;

[0052] Among them, a set of first conduits 532 for supplying spray water penetrate through both the upper oxide scale peeling unit 53 and the lower oxide scale peeling unit 54. U-shaped spray pipes 533 facing the roll end are arranged at the penetrating ends of the first conduits 532. Peeling mechanisms 8 connected to the first conduits 532 are also arranged on both sides of the reciprocating cycle driving unit 7 to spray and peel the outer oxide layer of the rolling plate at the roll end by using the spray water in the first conduits 532.

[0053] To solve the problem in the prior art that the water spraying mechanism of rolling equipment lacks a dynamically adaptable peeling structure and cannot effectively remove the dense oxide layer formed at high temperature, resulting in residual oxide scale embedding into the interior of the sheet during subsequent rolling, causing a decrease in interlayer bonding force and stress concentration. The above technical solution is now adopted to solve this problem. The above technical solution mainly consists of a roll drive device 1, rolls 2, a rolling sheet conveying base unit 3, a multi-axis adjusting arm 4, an outer oxide scale peeling module 5 for rolling sheets, a reciprocating circulation drive unit 7, and a peeling mechanism 8. The roll drive device 1 and the rolls 2 are the inherent structures of the iron sheet rolling equipment in the prior art. The roll drive device 1 serves as the main drive end of the device. On the one hand, it is used to drive the rolls 2 at the output end to move up and down to change the actual spacing between the two sets of rolls 2. On the other hand, it is used to drive each roll 2 to rotate to roll the metal sheet clamped between the two rolls 2. The rolling sheet conveying base unit 3 is a base structure for conveying the rolling sheet. On the one hand, it is used to stably convey the processed metal sheet between the two sets of rolls 2. On the other hand, it can also tilt and rotate to better pour out the sprayed water on the lower surface and the peeled oxide metal layer. The configured multi-axis adjusting arm 4 is a robotic arm structure that can be adjusted in multiple directions in the prior art and is used to support the outer oxide scale peeling module 5 at the output end to stably sleeve outside the metal sheet, so that the output end of the outer oxide scale peeling module 5 for rolling sheets can stably fit on the upper and lower surfaces of the metal sheet to be processed.

[0054] The outer oxide scale peeling module 5 for rolling sheets mainly consists of an upper oxide scale peeling unit 53 and a lower oxide scale peeling unit 54. The upper oxide scale peeling unit 53 and the lower oxide scale peeling unit 54 have the same structure but opposite orientations. The upper oxide scale peeling unit 53 is located on the upper side of the plate to be processed, while the lower oxide scale peeling unit 54 is located on the lower side of the plate to be processed. Therefore, the acting end of the upper oxide scale peeling unit 53 faces downward to peel the dense oxide layer on the upper surface of the plate to be processed, and the acting end of the lower oxide scale peeling unit 54 faces upward to peel the dense oxide layer on the lower surface of the plate to be processed. Both the upper oxide scale peeling unit 53 and the lower oxide scale peeling unit 54 penetrate into a set of first conduits 532. On the one hand, it is to supply water to the U-shaped spray pipe 533 so that the U-shaped spray pipe 533 can spray the plate to be processed during operation to remove the oxide layer. On the other hand, it is to supply water to the two sets of peeling mechanisms 8 arranged inside so that the sprayed water can act on the peeling surfaces of the peeling mechanisms 8 synchronously, further improving the peeling effect of the peeling mechanisms 8. To solve the problem in the prior art that the water spraying mechanism of rolling equipment lacks a dynamically adaptable peeling structure and cannot effectively remove the dense oxide layer formed at high temperature, resulting in residual oxide scale embedding into the interior of the sheet during subsequent rolling, causing a decrease in interlayer bonding force and stress concentration.

[0055] Such as Figures 1 to 11As shown in the figure, the outer scale peeling module 5 of the rolling plate includes a bidirectional electric telescopic rod 51 fixedly installed at the output end of the multi-axis adjusting arm 4. A mounting frame 52 is fixedly installed on the upper output end of the bidirectional electric telescopic rod 51. The upper scale peeling unit 53 includes a cavity housing 531 fixedly installed on the side of the mounting frame 52. A first conduit 532 penetrates through the interior of the cavity housing 531. The penetrating end of the first conduit 532 is used to connect to a water supply end. The penetrating end of the first conduit 532 is fixedly installed with a U-shaped spray pipe 533. A number of atomizing spray openings facing the roll end are formed on the pipe surface of the U-shaped spray pipe 533. An external expansion joint 534 is also fixedly installed at the position where the U-shaped spray pipe 533 is connected to the first conduit 532.

[0056] Among them, the bidirectional electric telescopic rod 51 arranged at the output end of the multi-axis adjusting arm 4 is also a telescopic rod structure that can be electrically controlled bidirectionally in the prior art. Its function is to control the upper scale peeling unit 53 and the lower scale peeling unit 54 at the upper and lower ends to expand and retract synchronously, so as to adaptively adjust the working surfaces of the upper scale peeling unit 53 and the lower scale peeling unit 54 to approach the metal plate. The cavity housing 531 is a housing structure with a cavity inside and an open side facing the metal plate. The side facing the metal plate is open to intermittently extend the peeling end. The configured U-shaped spray pipe 533 is also close to the open end of the cavity housing 531. The penetrating end of the first conduit 532 is used to connect to a water supply end. To ensure the flexibility of the device during operation, the side used to connect to the water supply end is connected by a hose.

[0057] As Figures 1 to 11 As shown in the figure, the reciprocating cycle driving unit 7 includes a socket frame 71 fixedly installed at the middle position inside the cavity housing 531. A servo motor 72 is fixedly installed on the surface of the socket frame 71. A first bevel gear head 73 is fixedly installed at the output end of the servo motor 72. Tooth plates 78 are fixedly installed on both sides of the socket frame 71. A second U-shaped support plate 74 is fixedly installed at the bottom of the tooth plate 78. A reciprocating threaded rod 75 is movably installed inside the second U-shaped support plate 74. A second bevel gear head 76 meshing with the first bevel gear head 73 is fixedly installed at the middle position of the reciprocating threaded rod 75. A limiting groove 77 is formed on the surface of the open end of the second U-shaped support plate 74. Peeling mechanisms 8 are arranged symmetrically on both sides of the second bevel gear head 76 through the limiting groove 77.

[0058] As Figures 1 to 11As shown, the peeling mechanism 8 includes nut sleeve blocks 81 slidably installed in the limit grooves 77 on both sides of the second bevel gear head 76. Leak-proof covers 82 are fixedly installed on the surfaces of the nut sleeve blocks 81. A number of reset spring rods 89 are fixedly installed at the inner bottom position of the leak-proof covers 82, and a ring sleeve 810 is fixedly installed on the reset ends of the reset spring rods 89. A hollow conduit 83 is sleeved inside the ring sleeve 810. An open cover 88 is fixedly installed at the bottom of the leak-proof cover 82. A cavity disc 813 which is wholly placed inside the open cover 88 is fixedly installed at the bottom of the hollow conduit 83. A number of groups of fan-shaped polishing coatings 814 are arranged at the bottom of the cavity disc 813.

[0059] Among them, the configured cavity disc 813 and the number of groups of fan-shaped polishing coatings 814 are both made of high-strength heat-resistant materials in the prior art. For example, tungsten carbide or ceramic coatings can be used for preparation to meet the requirements of high-temperature processing.

[0060] Such as Figures 1 to 11 As shown, the peeling mechanism 8 further includes a wave ring sleeve 87 fixedly installed at the upper side position inside the leak-proof cover 82. An outer extension rod 811 is fixedly installed at the position of the hollow conduit 83 flush with the wave ring sleeve 87. Ball bearings 812 which are slidably clamped in the circular openings of the wave ring sleeve 87 are movably installed at both side ends of the outer extension rod 811. A water receiving cover 84 which is communicated with the hollow conduit 83 is fixedly installed at one side where the hollow conduit 83 passes through the leak-proof cover 82. A gear ring 85 which meshes with the same-side tooth plate 78 is fixedly installed on the outer ring surface of the water receiving cover 84.

[0061] Among them, the configured wave ring sleeve 87 is a circular ring structure as a whole and is a wavy closed structure composed of smooth curves. The ball 812 is always attached to the circular opening of the wave ring sleeve 87 under the restoring elastic force of the restoring spring rod 89. During the rotation of the hollow conduit 83, the ball 812 attached to the circular opening of the wave ring sleeve 87 will move along the smooth curve of the wave ring sleeve 87. On one end of the cavity disc 813, it is manifested that the cavity disc 813 rotates while reciprocally extending out of the open mask 88. Because in the actual processing process, the outer surface temperature of the metal plate to be processed is extremely high, so with the deployment of the multi-axis adjusting arm 4 and the bidirectional electric telescopic rod 51, there is a certain gap between the open mask 88 and the metal plate to be processed instead of contact. By reciprocally controlling the intermittent extension of the cavity disc 813 through the wave ring sleeve 87, it is to make the cavity disc 813 intermittently approach and attach to the metal plate surface for grinding and peeling. The grinding and peeling end is set to reciprocally extend because the outer surface of the metal plate has a high temperature of about 1000 to 1200 degrees Celsius during the rolling process. Continuous grinding in this environment will cause plastic deformation of the substrate due to continuous pressure, such as depression and warping. Through the periodic retraction of the wave ring sleeve 87, the metal undergoes elastic recovery during the grinding interval to avoid the accumulation of plastic deformation, so as to utilize the intermittent period to release the work hardening effect and reduce the subsequent grinding resistance, especially for high strain rate sensitive materials such as multi-layer iron rolling plates.

[0062] Moreover, the further intermittent peeling work can also promote the oxide layer on the outer surface of the rolling plate to detach in a shell-like structure during the rolling process, directly increasing the removal effect of the oxide layer. Because the iron layer plate is different from the rolling of stainless steel and aluminum alloy, the main formation of pitting and cracks is due to the residual oxide scale of the iron layer plate. The pitting is formed by the oxide scale being pressed in, and the cracks are formed because the oxide scale hinders the metal flow. Therefore, the shell peeling mechanism can be imitated, and a gradient pressure grinding end is used to grind from a single action point to make the edge automatically peel off, reducing the damage to the substrate during the oxide layer peeling process. Specifically in the processing process of the rolling plate, its gradient peeling can be divided into:

[0063] The first stage: When the grinding coating 814 of the cavity disc 813 grinds a single point, it will grind off impurities such as magnetite and iron oxide on the outer layer of the oxide scale.

[0064] The second stage: During the stage when the cavity disc 813 intermittently retracts, microcracks will be generated in the inner layer of the oxide scale, that is, iron monoxide, due to the difference in thermal stress and mechanical stress.

[0065] The third stage: When the cavity disc 813 extends out again to work, it has left the previous grinding point. After the previous grinding point is ground, the surrounding area will complete peeling along the crack extension to avoid damaging the substrate.

[0066] As Figures 1 to 11 shown, sealing covers 86 are movably installed at the tops of the water receiving covers 84. A fourth conduit 9 that communicates with a first conduit 532 penetrating into the cavity housing 531 is connected to the outside of each of the sealing covers 86. A plurality of groups of leakage ports 815 are arranged in a circular pattern on the bottom surface of the cavity disc 813, and a communication cavity 816 that communicates with the plurality of groups of leakage ports 815 is provided inside the cavity disc 813.

[0067] Among them, the configured communication cavity 816 is intended to communicate the hollow conduit 83 with the inside of the cavity disc 813, so that the liquid in the water receiving cover 84 outside the hollow conduit 83 can be introduced onto the working surface of the cavity disc 813.

[0068] As Figures 1 to 11 shown, the lower scale stripping unit 54 has the same structure as the upper scale stripping unit 53. Outer extended water receiving covers 10 are fixedly connected to both sides of the cavity housing 531 in the lower scale stripping unit 54. A fifth conduit 11 is connected in communication between the outer extended connectors 534 in the lower scale stripping unit 54 and the upper scale stripping unit 53. A drain connector 12 is fixedly installed at the bottom position of the cavity housing 531 in the lower scale stripping unit 54.

[0069] Among them, the outer extended water receiving covers 10 configured on both sides of the cavity housing 531 in the lower scale stripping unit 54 are for collecting the high-temperature liquid sprayed from the metal plate and the upper scale stripping unit 53 during the processing. After collecting it into the cavity housing 531 in the lower scale stripping unit 54, it is discharged by the drain connector 12 at the bottom position. Connecting the fifth conduit 11 in communication between the outer extended connectors 534 in the lower scale stripping unit 54 and the upper scale stripping unit 53 is for using only one spray water supply end.

[0070] The specific working state of the stripping mechanism 8 is as follows:

[0071] First, the roll drive device 1 controls the two rolls 2 to start separating through the internally configured output end, reserving space for the plate to be rolled on the conveying end of the rolling plate conveying base unit 3. Immediately after heating the plate to be rolled to an appropriate temperature through the heating furnace, it is transferred to the rolling plate conveying base unit 3 and conveyed to between the two rolls 2 through the rolling plate conveying base unit 3.

[0072] Then, servo adjustment is performed through the multi-axis adjustment arm 4 to control the output end of the external scale stripping module 5 of the rolling plate to approach the plate to be rolled, and then the bidirectional electric telescopic rod 51 is used to adjust the distance between the upper scale stripping unit 53 and the lower scale stripping unit 54 when approaching the plate to be rolled.

[0073] Then, through the rotation of the first bevel gear head 73 at the output end of the servo motor 72, the engaged second bevel gear head 76 is driven to rotate synchronously. The rotation of the second bevel gear head 76 can control the rotation of the reciprocating threaded rod 75 inside the second U-shaped support plate 74, enabling the nut sleeve blocks 81 engaged on both sides of the second U-shaped support plate 74 to move back and forth along the limit groove 77. During the back-and-forth movement of the nut sleeve blocks 81, the gear ring 85 on the upper side of the hollow conduit 83 movably sleeved inside the leakage mask 82 can also move along the surface of the toothed plate 78. Since the gear ring 85 and the toothed plate 78 are in an engaged state, during the movement along the surface of the toothed plate 78, the gear ring 85 will also rotate synchronously. The rotation of the gear ring 85 can drive the water receiving cover 84 to rotate. Since the water receiving cover 84 is fixedly connected to the hollow conduit 83, the hollow conduit 83 can also be rotated. The outer side of the hollow conduit 83 is provided with outstretched rods 811 and balls 812 that are movably attached to the bottom surface of the wave ring sleeve 87. Therefore, during the rotation of the hollow conduit 83, its rotation trajectory is the same as the wave ring of the wave ring sleeve 87, causing the hollow conduit 83 to rotate and reciprocate up and down inside the leakage mask 82. And because the hollow conduit 83 is movably sleeved in the ring sleeve 810 through the return spring rod 89, it will always adhere to the wave ring sleeve 87 during the rotation and up-and-down reciprocation. Therefore, specifically, the cavity disc 813 at the side end of the hollow conduit 83 reciprocally extends, periodically pressing against the surface of the plate to be rolled. A polishing coating 814 is arranged on the fitting surface of the cavity disc 813, and the oxidation layer on the outer surface of the plate to be rolled can be polished using this polishing coating 814.

[0074] Finally, during the periodic reciprocating polishing process, spray water is introduced into the first conduit 532. Specifically, the spray water is introduced from the first conduit 532 of the upper scale peeling unit 53. A part of it enters the U-shaped spray pipe 533 of the upper scale peeling unit 53 and is atomized and sprayed outwards through the U-shaped spray pipe 533. A part of it enters the water receiving cover 84 in the upper scale peeling unit 53 through the fourth conduit 9, enters the hollow conduit 83 through the water receiving cover 84, then enters the communication cavity 816 outside the hollow conduit 83, and finally is discharged through the leak port 915 on the cavity disc 813, directly acting on the polishing surface. Another part of the spray water in the first conduit 532 of the upper scale peeling unit 53 enters the fifth conduit 11 through the outer expansion joint 534 and enters the lower scale peeling unit 54 through the fifth conduit 11. Since the lower scale peeling unit 54 has the same structure as the upper scale peeling unit 53, the flow path of the spray water in the lower scale peeling unit 54 will not be elaborated here.

[0075] During the staged grinding process of the upper scale stripping unit 53 and the lower scale stripping unit 54, the bidirectional electric telescopic rod 51 will also reciprocate, changing the interval between the two units. The purpose is to provide an interval difference for a period of time so that the rolling mill 2 can perform rolling processing on the plate to be rolled during this interval difference, and the processing is carried out in a reciprocating cycle.

[0076] As Figures 1 to 11 shown, a stripping water heat energy circulation module 6 is further arranged on the surface of the roll drive device 1. The stripping water heat energy circulation module 6 includes a first U-shaped support plate 61 fixedly installed between two groups of rolls 2. Protective frames 62 are fixedly installed at both side ends of the first U-shaped support plate 61. The sides of the protective frames 62 facing the plate to be rolled are in an open state, and two sets of air guide cavity covers 63, one above the other, are fixedly installed at the open ends. A protective gas connector 65 is fixedly installed at the middle position of the bottom of the first U-shaped support plate 61. A second conduit 64 communicating with the two air guide cavity covers 63 on both sides is connected to the protective gas connector 65. A third conduit 66 penetrating into the two sets of air guide cavity covers 63, one above the other, is fixedly installed in each protective frame 62. The penetrating end of the third conduit 66 is hermetically connected to the drainage connector 12 through a hose to reuse the sprayed water after spraying, and the end of the third conduit 66 penetrating out of the protective frame 62 is conveyed to the waste water purification end through a hose.

[0077] Among them, the configured first U-shaped support plate 61 does not interfere with the two groups of rolls 2 because the radii of the two groups of rolls 2 are long enough, and on the other hand, the output ends of the two groups of rolls 2 extend outwards. The extended distance, that is, the gap between the two groups of rolls 2 and the surface of the roll drive device 1, can accommodate the stripping water heat energy circulation module 6 to avoid interference between the stripping water heat energy circulation module 6 and the two groups of rolls 2. The two sets of air guide cavity covers 63 are arranged one above the other, and the air outlet is in an inclined state as a whole, all facing the end to be processed.

[0078] Among them, the configured protective gas connector 65 is a connector structure controlled by an electric valve in the prior art and is used to introduce protective gas. Because during the rolling processing of the rolled plate, in order to ensure the stability of the rolling end and avoid secondary oxidation of the metal, protective gas will be introduced. Because after descaling and before rolling, the metal will regenerate scale when exposed to air. The so-called descaling is the spraying and stripping work of the outer scale stripping module 5 of the rolled plate. However, the density of the inert gas and the air curtain coverage effect are generally poor, so the stripping water heat energy circulation module 6 is provided to assist in the work.

[0079] Specifically, during the process of the multi-axis adjustment arm 4 controlling the operation of the rolling plate external scale peeling module 5, the spray water ejected from the rolling plate external scale peeling module 5 will increase in temperature after contacting the high-temperature metal plate. After being collected by the outer extended water receiving covers 10 on both sides of the lower scale peeling unit 54, it can be discharged from the drain joint 12 and introduced into the third conduit 66. Therefore, the high-temperature spray water will enter the interior of the air guiding cavity cover 63 through the third conduit 66, heating the interior of the air guiding cavity cover 63, so that the gas discharged from the air guiding cavity cover 63 has a certain temperature. On the one hand, this temperature can directly act on the rolling end. On the other hand, combining the protective gas protection system with the waste heat recovery of descaling wastewater can improve the energy-saving efficiency of the entire system, reduce the temperature difference between the high-temperature steel billet and the cold gas during rolling, reduce thermal stress, increase the density of inert gas, and enhance the air curtain coverage effect.

[0080] As Figures 1 to 11 shown, the rolling plate conveying base unit 3 includes a first hinged base 31. At the middle position of the upper surface of the first hinged base 31, an outer open U-shaped support plate 32 is movably hinged. At both end positions of the outer open U-shaped support plate 32, rolling plate conveying rollers 33 are fixedly installed, and lateral limiting frames 34 are fixedly installed on both ends of the rolling plate conveying rollers 33. At the four corner positions of the first hinged base 31, second hinged bases 35 are fixedly installed, and on each second hinged base 35, an electric telescopic rod 36 that is movably connected to the same side corner of the outer open U-shaped support plate 32 is hinged.

[0081] Among them, the configured rolling plate conveying base unit 3 has two functions. On the one hand, it conveys the rolling plate. On the other hand, it cooperates with the peeling water heat energy recycling module 6 to better recover the peeling water for heat energy recycling. The specific working state is as follows:

[0082] First, when the rolling mill rolls, the electric telescopic rods 36 hinged on the second hinged bases 35 on the four sides of the first hinged base 31 cooperate to make the outer open U-shaped support plate 32 in a horizontal state. Then, the rolling plate conveying rollers 33 on both sides are opened, and the rolling plate placed on the surface is stably conveyed between the processing rollers through the rolling plate conveying rollers 33.

[0083] Then, after the rolling plate external scale peeling module 5 finishes working, the rolling mill 2 can be separated up and down through the roll drive device 1 so that the rolling plate is not in a clamped state, and in cooperation with the electric telescopic rods 36 hinged on the second hinged bases 35 on the four sides of the first hinged base 31, the outer open U-shaped support plate 32 is tilted left and right to make the spray water remaining on the surface of the rolling plate slide away better.

[0084] When the present invention is in use, in order to better collect the sprayed water, a corresponding water collection frame can also be configured at the bottom of the first hinge base 31, and in order to ensure the stability of the collected sprayed water, a filtering structure can be configured at the collection end.

[0085] The present invention covers any alternatives, modifications, equivalent methods and solutions made on the essence and scope of the present invention. In order to enable the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without these detailed descriptions. In addition, in order to avoid unnecessary confusion to the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0086] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
