Description

Technical Field

[0001] This invention relates to the field of hot-rolled plate processing technology, and in particular to a device for removing iron oxide scale from the surface of hot-rolled plates. Background Technology

[0002] Hot-rolled steel sheets, as a type of sheet metal, are classified according to their applications into carbon structural steel hot-rolled sheets, low-alloy structural steel hot-rolled sheets, carbon tool steel hot-rolled sheets, stainless steel hot-rolled sheets, and so on. During the hot-rolling process, the high temperature of the hot-rolled sheet, upon contact with air, causes iron oxide scale to form on its surface. Since hot-rolled sheets undergo subsequent processes such as leveling, if iron oxide scale is present on the surface, it can be pressed into the sheet, causing surface damage. In other words, the iron oxide scale affects subsequent processing and the quality of the hot-rolled sheet. Therefore, it is crucial to remove the iron oxide scale from the surface of the hot-rolled sheet promptly during processing.

[0003] The traditional method for removing iron oxide scale from the surface of hot-rolled steel plates involves installing high-pressure nozzles along the plate's conveying path to remove the scale through the impact of high-pressure water. While this method has some effect, it is difficult to completely remove the scale. In actual production, some scale remains adhered to and retained on the surface of the hot-rolled plate after removal, which is detrimental to its later use. Furthermore, under this process, the detached scale is washed away by the high-pressure water flow and accumulates in the water tank. As the amount of scale in the tank increases, blockages easily occur, making processing difficult and severely impacting continued production. Summary of the Invention

[0004] The purpose of this invention is to provide a device for removing iron oxide scale from the surface of hot-rolled steel plates.

[0005] The technical solution to achieve the objective of this invention is: a device for removing iron oxide scale from the surface of hot-rolled steel plates, comprising a frame, on which a row of idler rollers are horizontally arranged, each idler roller being rotatably mounted on the frame, and a grinding mechanism being provided on each of the axial sides of each idler roller, the grinding mechanism comprising a mounting frame, a plurality of conveying rollers and a plurality of grinding rollers, the mounting frame being rotatably mounted on the frame via a rotating shaft, the rotating shaft being horizontal and perpendicular to the idler rollers, the mounting frame being driven by a drive transmission mechanism to rotate along the rotating shaft, the plurality of conveying rollers and the plurality of grinding rollers being rotatably mounted on the mounting frame, the plurality of conveying rollers being driven by a first drive mechanism to rotate synchronously, the plurality of grinding rollers being driven by a second drive mechanism to rotate synchronously, the conveying rollers and the grinding rollers being arranged along the same straight line, the arrangement direction of the conveying rollers and the grinding rollers being parallel to the arrangement direction of the idler rollers, and the conveying rollers, the grinding rollers and the idler rollers being parallel.

[0006] Furthermore, the conveying rollers and the grinding rollers are arranged alternately at intervals.

[0007] Furthermore, the drive transmission mechanism includes a worm gear and a drive motor. The worm gear is horizontally and rotatably mounted on the frame. The worm gear has two threaded portions with opposite rotation directions. Each of the two rotating shafts of the two grinding mechanisms is equipped with a worm wheel, and the two worm wheels mesh one-to-one with the two threaded portions on the worm gear. The mounting frames of the two grinding mechanisms can be driven by two independent drive transmission mechanisms, or by a single drive transmission mechanism as described above. Compared to being driven by two independent drive transmission mechanisms, when the drive transmission mechanism of the present invention simultaneously drives the mounting frames of the two grinding mechanisms, the rotation of the two grinding mechanisms is more synchronized, which is more conducive to the uniform grinding of the iron oxide scale on both sides.

[0008] Furthermore, within each of the grinding mechanisms, a first belt assembly is fitted onto all adjacent pairs of conveyor rollers. The first drive mechanism is fixedly mounted on the mounting frame and is drively connected to one of the conveyor rollers. During operation, after the first drive mechanism drives one of the conveyor rollers to rotate, all adjacent conveyor rollers in the grinding mechanism are driven sequentially, achieving synchronous rotation. This configuration is simple in structure and provides a high synchronization rate for the conveyor roller rotation. The first drive mechanism can be, but is not limited to, a motor.

[0009] Furthermore, within each of the grinding mechanisms, a second belt assembly is fitted onto all adjacent pairs of grinding rollers. The second drive mechanism is fixedly mounted on the mounting frame and is connected to one of the grinding rollers via a transmission connection. During operation, after the second drive mechanism drives one of the grinding rollers to rotate, all adjacent grinding rollers in the grinding mechanism are driven sequentially, achieving synchronous rotation. This configuration is simple in structure and provides a high synchronization rate for the grinding roller rotation. The second drive mechanism can be, but is not limited to, a motor.

[0010] Furthermore, a screw is rotatably mounted on the mounting frame, the screw being parallel to the conveying roller. The rotating shaft has a threaded hole, and the screw passes through and is threadedly engaged with the threaded hole. Rotating the screw, under the threaded engagement of the screw and the threaded hole, allows the mounting frame and the entire grinding mechanism to move in a direction parallel to the screw's axial direction. This movement allows for adjustment of the distance between the two grinding mechanisms. This adjustable distance enables the hot-rolled plate surface oxide scale removal device of the present invention to be applicable to grinding hot-rolled plates of different thicknesses, greatly improving application flexibility.

[0011] Furthermore, a rotary handwheel is installed at the end of the screw. The rotary handwheel facilitates the rotation of the screw and improves the ease of adjustment.

[0012] Furthermore, each of the grinding mechanisms is also provided with a corresponding support beam, which is fixed to the frame. The support beam is located on the side of the rotating shaft away from the idler roller and is located below the mounting frame. When the mounting frame is in a horizontal position, the support beam is in contact with the bottom of the mounting frame. The support beam is used to support the mounting frame in the horizontal position, making the stability better during operation, especially when the grinding mechanism carries the hot-rolled plate.

[0013] Furthermore, the two grinding mechanisms are symmetrical along a row of rollers.

[0014] Furthermore, the frame is a frame structure. Compared to structures such as pillars and beams, frame structures are more robust.

[0015] Furthermore, a hopper is connected to the bottom of the frame. The hopper is vertically continuous, with the upper opening diameter larger than the lower opening diameter. This hopper design facilitates the collection of iron oxide scale generated during grinding.

[0016] This invention relates to a device for removing iron oxide scale from the surface of hot-rolled steel plates. When the grinding rollers of the grinding mechanism grind the hot-rolled steel plate, the grinding rollers make hard contact with the hot-rolled steel plate with a large contact area. Under this simultaneous, large-area hard stress, the iron oxide scale on the surface of the hot-rolled steel plate, especially large pieces of iron oxide scale, is easily broken and detached. Furthermore, during the grinding process, the conveying rollers can drive the hot-rolled steel plate to reciprocate on the support rollers. While the hot-rolled steel plate is being ground, on the one hand, the grinding rollers can perform comprehensive grinding of the hot-rolled steel plate, resulting in more thorough and uniform removal of the iron oxide scale, preventing incomplete removal of some iron oxide scale; on the other hand, the vibration of the hot-rolled steel plate during its movement makes it easier for the iron oxide scale to fall off.

[0017] The present invention provides a device for removing iron oxide scale from the surface of hot-rolled steel plates. Furthermore, by rotating the mounting frame of the grinding mechanism onto the frame via the rotating shaft, the grinding mechanism and the hot-rolled steel plate on it can be flipped and tilted under the drive of the transmission mechanism, achieving repositioning. Compared to a flat hot-rolled steel plate or a method where the hot-rolled steel plate is positioned above it, in the present invention's device for removing iron oxide scale from the surface of hot-rolled steel plates, the grinding mechanism and the hot-rolled steel plate are flipped and tilted. After repositioning, when the grinding roller of the grinding mechanism grinds the hot-rolled steel plate, the broken iron oxide scale on the hot-rolled steel plate has space to fall. Since there is no supporting structure below the broken iron oxide scale, it easily falls off under its own weight.

[0018] The present invention relates to a device for removing iron oxide scale from the surface of hot-rolled steel plates. The two grinding mechanisms are located on both sides of the idler roller. During operation, the two grinding mechanisms simultaneously grind the two sides of the hot-rolled steel plate, resulting in high efficiency and speed in removing iron oxide scale from the two sides of the hot-rolled steel plate.

[0019] This invention relates to a device for removing iron oxide scale from the surface of hot-rolled steel plates. The grinding mechanism uses grinding rollers to hard-grind the hot-rolled steel plate, making the iron oxide scale on the plate easily breakable. The conveying rollers of the grinding mechanism transport the hot-rolled steel plate, causing it to reciprocate. This vibration and side-mounted grinding make the broken iron oxide scale on the hot-rolled steel plate easily detach and fall off. During grinding, the iron oxide scale is easily broken and detached, and the reciprocating motion of the hot-rolled steel plate ensures thorough and uniform removal of the iron oxide scale. Therefore, this invention's device for removing iron oxide scale from hot-rolled steel plates has a good effect on removing iron oxide scale. Furthermore, the two grinding mechanisms grind from both sides of the hot-rolled steel plate, resulting in high efficiency and speed in removing the iron oxide scale.

[0020] Furthermore, during the hot-rolled plate flipping and grinding process, including the flipping of the grinding mechanism and the flipping of the hot-rolled plate, the hot-rolled plate on the surface of the hot-rolled plate of the present invention is flipped simultaneously during the flipping of the two grinding mechanisms. In other words, the flipping mechanism of the grinding mechanism and the flipping mechanism of the hot-rolled plate are combined into one. The structure of the hot-rolled plate surface oxide scale removal device of the present invention is simple and does not require a separate flipping mechanism for the hot-rolled plate. Moreover, after the hot-rolled plate is flipped and placed on its side, the side-standing hot-rolled plate stands on the support roller and reciprocates on the support roller. The rolling of the support roller greatly reduces the running obstacles of the hot-rolled plate, providing convenient conditions for the labor-saving and smooth operation of the hot-rolled plate, making the grinding process more balanced and smooth.

[0026] The specific embodiments of the hot-rolled plate surface oxide scale removal device of the present invention will be described in detail below with reference to the accompanying drawings:

[0027] like Figures 1 to 5As shown, a device for removing iron oxide scale from the surface of hot-rolled steel plates includes a frame 10. A row of idler rollers 1 are horizontally arranged on the frame 10, and each idler roller 1 is rotatably mounted on the frame 10. A grinding mechanism 2 is provided on each of the axial sides of each idler roller 1. The grinding mechanism 2 includes a mounting frame 21, a plurality of conveying rollers 22, and a plurality of grinding rollers 23. The mounting frame 21 is rotatably mounted on the frame 10 via a rotating shaft 211, which is horizontal and perpendicular to the idler rollers 1. The mounting frame 21 is connected to a drive transmission mechanism 24 and is driven by the drive transmission mechanism 24 to move along the rotating shaft 21. 1. Rotation: Several conveying rollers 22 and several grinding rollers 23 can be rotatably mounted on the mounting frame 21. Several conveying rollers 22 are driven by a first driving mechanism 221 and can rotate synchronously. Several grinding rollers 23 are driven by a second driving mechanism 231 and can rotate synchronously. The conveying rollers 22 and the grinding rollers 23 are arranged along the same straight line. The arrangement direction of the conveying rollers 22 and the grinding rollers 23 is parallel to the arrangement direction of the support rollers 1. The conveying rollers 22, the grinding rollers 23 and the support rollers 1 are all parallel.

[0028] This invention relates to a device for removing iron oxide scale from the surface of hot-rolled steel plates. The grinding mechanism 2 is used to convey, flip, and grind the hot-rolled steel plates. The mounting frame 21 of the grinding mechanism 2 is rotatably mounted on the frame 10 via a rotating shaft 211. The mounting frame 21 is rotatable. Under the condition that the mounting frame 21 is rotatable, the mounting frame 21 is connected to the drive transmission mechanism 24, which provides power for the rotation of the mounting frame 21, ultimately ensuring that the grinding mechanism 2 can flip the hot-rolled steel plates. Conveying rollers 22 and grinding rollers 23 are arranged at intervals on the grinding mechanism 2. The upper surfaces of both the conveying rollers 22 and the grinding rollers 23 protrude from the mounting frame 21 and are located on the same horizontal plane. The conveying rollers 22 are used to convey the hot-rolled steel plates, and the grinding rollers 23 are used to grind the hot-rolled steel plates.

[0029] In the hot-rolled plate surface oxide scale removal device of the present invention, before the hot-rolled plate is conveyed to it, the two grinding mechanisms 2 are placed horizontally. After the hot-rolled plate from the production line is conveyed into the hot-rolled plate surface oxide scale removal device of the present invention, the hot-rolled plate is located on the idler roller 1 and the two grinding mechanisms 2, and is supported by the idler roller 1 and the two grinding mechanisms 2. When the idler roller 1 and the two grinding mechanisms 2 support the hot-rolled plate together, the width of the hot-rolled plate covering the two grinding mechanisms 2 is not the same, that is, the hot-rolled plate is not symmetrically located on the two grinding mechanisms 2, but is in an eccentric state, that is, the part of the hot-rolled plate on one side of the grinding mechanism 2 is larger, and the part on the other side of the grinding mechanism 2 is smaller.

[0030] In this invention, a device for removing iron oxide scale from the surface of hot-rolled steel plates is used. The hot-rolled steel plates are asymmetrically positioned on two grinding mechanisms 2. The first drive mechanism 221 of the two grinding mechanisms 2 drives the conveying rollers 22 to rotate synchronously, completely conveying the hot-rolled steel plates onto the device and stopping them at a suitable position. Then, the drive transmission mechanism 24 of the two grinding mechanisms 2 drives the rotating shaft 211 to rotate, causing the mounting frames 21 of the two grinding mechanisms 2 to flip in opposite directions. The outer sides of the two mounting frames 21 move upwards and stand upright relative to each other. During the flipping and uprighting process of the two mounting frames 21, the hot-rolled steel plates on the two grinding mechanisms 2 are asymmetrically placed, with one side rotating higher and the other side rotating lower, resulting in an inclined state. Under its own weight and the gradually forming clamping action of the two grinding mechanisms 2, the inclined hot-rolled steel plates flip into a side-standing state, with the side-standing hot-rolled steel plates positioned on the support rollers 1. When the two grinding mechanisms 2 are flipped to a parallel, side-standing position to clamp the side-standing hot-rolled plate, the drive transmission mechanism 24 stops operating. Then, the first drive mechanism 221 and the second drive mechanism 231 of the two grinding mechanisms 2 are activated. The first drive mechanism 221 drives the conveying roller 22, which in turn drives the hot-rolled plate to reciprocate on the support roller 1. The second drive mechanism 231 drives the grinding roller 23 to rotate. The grinding roller 23, rotating within the two mounting frames 21, grinds the two side surfaces of the hot-rolled plate reciprocating on the support roller 1, removing the iron oxide scale from the two side surfaces of the hot-rolled plate.

[0031] This invention relates to a device for removing iron oxide scale from the surface of hot-rolled steel plates. After the iron oxide scale on both sides of the hot-rolled steel plate is polished, the first drive mechanism 221 and the second drive mechanism 231 of the two polishing mechanisms 2 stop operating. The drive transmission mechanism 24 of the two polishing mechanisms 2 drives the rotating shaft 211 to rotate, causing the mounting frames 21 of the two polishing mechanisms 2 to flip over, with the upper ends of the two mounting frames 21 flipping outward. During the outward flipping of the two mounting frames 21, the two sides of the hot-rolled steel plate are no longer clamped by the two polishing mechanisms 2. Since the thickness of the hot-rolled steel plate is usually small, after the two sides are no longer clamped by the two polishing mechanisms 2, the hot-rolled steel plate tilts and leans against one of the polishing mechanisms 2. As the two polishing mechanisms 2 gradually flip over to a flat position, the lower end of the hot-rolled steel plate when tilted gradually slides onto the other polishing mechanism 2, so that after the two polishing mechanisms 2 are completely flipped to a flat position, the hot-rolled steel plate also becomes flat and is supported by the two polishing mechanisms 2. Subsequently, the first drive mechanism 221 of the two grinding mechanisms 2 is driven, and the conveying roller 22 rotates synchronously to output the ground hot-rolled plate.

[0032] The hot-rolled plate surface iron oxide scale removal device of the present invention, when the grinding roller 23 of the grinding mechanism 2 grinds the hot-rolled plate, the grinding roller 23 makes hard contact with the hot-rolled plate and the contact area is large. Under the simultaneous large-area hard force, the iron oxide scale on the surface of the hot-rolled plate, especially the whole piece of iron oxide scale, is easily broken and detached. In addition, during the grinding process of the grinding roller 23, the conveying roller 22 can drive the hot-rolled plate to reciprocate on the support roller 1. When the hot-rolled plate is reciprocated and ground at the same time, on the one hand, the grinding roller 23 can grind the hot-rolled plate comprehensively, and the iron oxide scale on the hot-rolled plate is ground more thoroughly and evenly, without the situation that some iron oxide scale is not removed; on the other hand, the vibration of the hot-rolled plate during the movement makes the iron oxide scale on it easier to fall off.

[0033] The hot-rolled plate surface oxide scale removal device of the present invention further improves the positioning by rotating the mounting frame 21 of the grinding mechanism 2 onto the frame 10 via the rotating shaft 211. This allows the grinding mechanism 2 and the hot-rolled plate on it to be flipped and tilted under the drive of the drive transmission mechanism 24, achieving a displacement. Compared to the method of placing the hot-rolled plate flat and having it rotate from above, in the hot-rolled plate surface oxide scale removal device of the present invention, the grinding mechanism 2 and the hot-rolled plate are flipped and tilted. After displacement, when the grinding roller 23 of the grinding mechanism 2 grinds the hot-rolled plate, the broken oxide scale on the hot-rolled plate has a falling space. Since there is no supporting structure below the broken oxide scale, it easily falls off under its own weight.

[0034] The present invention relates to a device for removing iron oxide scale from the surface of hot-rolled steel plates. The two grinding mechanisms 2 are located on both sides of the roller 1. During operation, the two grinding mechanisms 2 simultaneously grind the two sides of the hot-rolled steel plate, resulting in high efficiency and speed in removing iron oxide scale from the two sides of the hot-rolled steel plate.

[0035] This invention relates to a device for removing iron oxide scale from the surface of hot-rolled steel plates. The grinding roller 23 of the grinding mechanism 2 performs hard grinding on the hot-rolled steel plate, making the iron oxide scale on the plate easily breakable. The conveying roller 22 of the grinding mechanism 2 transports the hot-rolled steel plate, causing it to reciprocate. This vibration and side-mounted grinding make the broken iron oxide scale on the hot-rolled steel plate easily detach and fall off. During grinding, the iron oxide scale is easily broken and detached, and the reciprocating motion of the hot-rolled steel plate ensures thorough and uniform removal of the iron oxide scale. Therefore, this invention's device for removing iron oxide scale from the surface of hot-rolled steel plates has a good effect on removing iron oxide scale. Furthermore, the two grinding mechanisms 2 perform grinding on both sides of the hot-rolled steel plate, resulting in high efficiency and speed in removing the iron oxide scale.

[0036] Furthermore, during the hot-rolled plate flipping and grinding process, including the flipping of the grinding mechanism 2 and the flipping of the hot-rolled plate, the iron oxide scale removal device for the hot-rolled plate surface of the present invention simultaneously achieves the flipping of the hot-rolled plate on both grinding mechanisms 2 during the flipping process. In other words, the flipping mechanism of the grinding mechanism 2 and the flipping mechanism of the hot-rolled plate are combined into one. The structure of the iron oxide scale removal device for the hot-rolled plate surface of the present invention is simple, and there is no need to set up a separate flipping mechanism for the hot-rolled plate. Moreover, after the hot-rolled plate is flipped and placed on its side, the side-placed hot-rolled plate stands on the support roller 1 and reciprocates on the support roller 1. The rolling of the support roller 1 greatly reduces the running obstacles of the hot-rolled plate, providing convenient conditions for the labor-saving and smooth operation of the hot-rolled plate, making the grinding process more balanced and smooth.

[0037] The present invention relates to a device for removing iron oxide scale from the surface of hot-rolled steel plates. Based on the operation of this device, the rotation angle of the mounting frame 21 is clearly defined. The rotation angle of the mounting frame 21 is limited to the ability of the mounting frame 21 to repeatedly change between a flat position and a side-standing position. That is, the mounting frame 21 can at least rotate from a flat position to a side-standing position, and simultaneously, it can also rotate back from a side-standing position to a flat position. Further details regarding this will not be elaborated upon in the present invention.

[0038] In the hot-rolled steel plate surface oxide scale removal device of the present invention, preferably, the conveying rollers 22 and the grinding rollers 23 are arranged alternately at intervals. Alternatively, the conveying rollers 22 and the grinding rollers 23 can be arranged alternately at intervals, or two conveying rollers 22 can be spaced apart with one grinding roller 23, or two grinding rollers 23 can be spaced apart with one conveying roller 22, or other arrangements are also possible. Compared to other arrangements, when the conveying rollers 22 and the grinding rollers 23 are arranged alternately at intervals, the conveying of the hot-rolled steel plate is more reliable, and the grinding of the hot-rolled steel plate is more uniform.

[0039] In a preferred embodiment of the hot-rolled steel plate surface oxide scale removal device of the present invention, the drive transmission mechanism 24 includes a worm gear 241 and a drive motor 242. The worm gear 241 is horizontally rotatably mounted on the frame 10. The worm gear 241 has two threaded portions 2410 with opposite rotation directions. Each of the two rotating shafts 211 of the two grinding mechanisms 2 is equipped with a worm wheel 243, and the two worm wheels 243 mesh with the two threaded portions 2410 on the worm gear 241 in a one-to-one correspondence. When the two grinding mechanisms 2 need to be rotated, the worm gear 241 is rotated, and under the meshing action of the worm wheels 243 and the worm gear 241, the two grinding mechanisms 2 rotate synchronously along their respective rotating shafts 211.

[0040] In this invention, the device for removing iron oxide scale from the surface of hot-rolled steel plates allows the mounting frames 21 of the two grinding mechanisms 2 to be driven by two independent drive transmission mechanisms, or by a single drive transmission mechanism as described above. Compared to being driven by two independent drive transmission mechanisms, the drive transmission mechanism 24 of this invention simultaneously drives the mounting frames 21 of both grinding mechanisms 2, resulting in more synchronized rotation of the two grinding mechanisms 2 and facilitating more uniform grinding of the iron oxide scale on both sides.

[0041] In this invention, a device for removing iron oxide scale from the surface of hot-rolled steel plates is preferably provided in which, within each grinding mechanism 2, a first belt assembly 222 is fitted onto all adjacent pairs of conveyor rollers 22. A first drive mechanism 221 is fixedly mounted on the mounting frame 21 and is drively connected to one of the conveyor rollers 22. During operation, after the first drive mechanism 221 drives one of the conveyor rollers 22 to rotate, all adjacent conveyor rollers 22 in the grinding mechanism 2 are driven sequentially to achieve synchronous rotation. This configuration is simple in structure and achieves a high synchronization rate in the rotation of the conveyor rollers 22. The first drive mechanism 221 can be, but is not limited to, a motor.

[0042] In this invention, a device for removing iron oxide scale from the surface of hot-rolled steel plates is preferably provided in which, within each grinding mechanism 2, a second belt assembly 232 is fitted onto all adjacent grinding rollers 23. A second drive mechanism 231 is fixedly mounted on the mounting frame 21 and is drively connected to one of the grinding rollers 23. During operation, after the second drive mechanism 231 drives one of the grinding rollers 23 to rotate, all adjacent grinding rollers 23 in the grinding mechanism 2 are driven sequentially, achieving synchronous rotation. This configuration is simple in structure and provides a high synchronization rate for the rotation of the grinding rollers 23. The second drive mechanism 231 can be, but is not limited to, a motor.

[0043] The present invention relates to a device for removing iron oxide scale from the surface of hot-rolled steel plates. The first belt assembly 222 and the second belt assembly 232 each include two pulleys respectively mounted on two adjacent rollers and a belt mounted on the two pulleys. The first belt assembly 222 and the second belt assembly 232 are conventional structures, and the present invention will not elaborate further on them.

[0044] In this invention, a hot-rolled steel plate surface oxide scale removal device preferably includes a screw 25 rotatably mounted on the mounting frame 21. The screw 25 is parallel to the conveying roller 22. The rotating shaft 211 has a threaded hole 212, through which the screw 25 passes and is threadedly engaged with the threaded hole 212. Rotating the screw 25 allows the mounting frame 21 and the entire grinding mechanism 2 to move in a direction parallel to the axial direction of the screw 25 under the threaded engagement of the screw 25 and the threaded hole 212. This movement allows for adjustment of the distance between the two grinding mechanisms 2. This adjustable distance enables the hot-rolled steel plate surface oxide scale removal device to be applied to grinding hot-rolled steel plates of different thicknesses, greatly improving application flexibility.

[0045] In this invention, a device for removing iron oxide scale from the surface of hot-rolled steel plates is provided. Each mounting frame 21 may have one, two, or multiple screws 25 corresponding to it; preferably, each mounting frame 21 has two screws 25 corresponding to it, with the two screws 25 located at opposite ends of the mounting frame 21. Figure 2 As shown.

[0046] In the hot-rolled steel plate surface oxide scale removal device of the present invention, preferably, a rotating handwheel 251 is installed at the end of the screw 25. The rotating handwheel 251 facilitates the rotation of the screw 25 and improves the convenience of adjustment.

[0047] In the hot-rolled plate surface oxide scale removal device of the present invention, preferably, each grinding mechanism 2 is also provided with a corresponding support beam 26. The support beam 26 is fixed on the frame 10, and is located on the side of the rotating shaft 211 away from the idler roller 1. The support beam 26 is located below the mounting frame 21. When the mounting frame 21 is in a flat position, the support beam 26 is in contact with the bottom of the mounting frame 21. The support beam 26 is used to support the mounting frame 21 in the flat position, so as to improve the stability during operation, especially when the grinding mechanism 2 carries the hot-rolled plate.

[0048] In the present invention, the iron oxide scale removal device for hot-rolled plate surface is preferably configured such that the two grinding mechanisms 2 are symmetrical along a row of rollers 1.

[0049] In this invention, the device for removing iron oxide scale from the surface of hot-rolled steel plates preferably includes a frame structure 10. Compared to structures such as pillars and beams, the frame structure offers greater stability.

The hopper 101 is vertically continuous, and the upper opening diameter of the hopper 101 is larger than the lower opening diameter. The hopper 101 facilitates the collection of iron oxide scale generated during grinding.

[0051] For those skilled in the art, without departing from the concept of this invention, several simple deductions or substitutions can be made, and all such deductions or substitutions should be considered to fall within the scope of protection of this invention.
