Description

Technical Field

[0001] The present application relates to the technical field of steel rolling, and in particular to a rough intermediate roller removal device for steel rolling. Background Art

[0002] Steel rolling is a production process that rolls steel billets or ingots into steel products with specific shapes, sizes and properties. The steel rolling process usually includes heating, rough rolling, intermediate rolling, finishing rolling, cooling and finishing processes, and the transfer of steel billets in various processes is mainly carried out through conveyor tracks.

[0003] However, after the steel billets are heated and roughly rolled, some of them will have problems such as bending, twisting, and surface defects, resulting in unqualified steel billets. After the unqualified steel billets undergo the intermediate rolling process, the existing surface defects and other problems will continue to expand, thereby reducing the quality of the final products and causing obvious deficiencies. Utility Model Content

[0004] In order to improve the production quality of steel rolling, the present application provides a steel rolling rough intermediate roller rejection device.

[0005] The present application provides a steel rolling rough intermediate roller removal device that adopts the following technical solutions:

[0006] A rough intermediate roller rejection device for steel rolling comprises a frame, a plurality of conveyor rollers equidistantly and evenly connected in rotation in the length direction of the frame, a connecting shaft fixedly connected to one side of the frame, a plurality of push plates rotatably connected to the connecting shaft, each of the push plates is arranged in a gap between adjacent conveyor rollers, a collecting table is provided on the side of the frame close to the connecting shaft, a conveyor belt is provided on the collecting table, a rejection component is provided on the frame, the rejection component drives the plurality of push plates to rotate synchronously around the connecting shaft, when the rejection component is not in operation, the top surface height of the push plate is below the top surface of the conveyor roller, and the length direction of the horizontal section of the push plate is parallel to the length direction of the conveyor roller.

[0007] By adopting the above technical solution, when the conveying roller conveys the steel billet, the steel billet moves above the push plate. When unqualified steel billets appear, the rejection component drives the push plate to rotate upward around the connecting shaft toward the collection table. When the push plate rotates, it drives the steel billet to move upward and gradually forms an inclined slope. The unqualified steel billets slide along the inclined push plate and fall onto the conveyor belt. The conveyor belt transports the unqualified steel billets out of the collection table, and then the rejection component drives the push plate to reset. This arrangement realizes the timely rejection of unqualified steel billets, prevents unqualified steel billets from entering the intermediate rolling process, and thus improves the production quality of steel rolling.

[0008] Optionally, the rejection assembly includes a hydraulic cylinder corresponding to the multiple push plates one by one, the hydraulic cylinder is arranged on the side of the frame away from the connecting axis, the end of the piston rod of the hydraulic cylinder is hinged with a drive rod, and the end of the drive rod away from the hydraulic cylinder is hinged to the vertical section of the push plate. When the rejection assembly is not in operation, the piston rod of the hydraulic cylinder is in an extended state.

[0009] By adopting the above technical solution, when rejection is required, the piston rod of the hydraulic cylinder retracts, and the piston rod drives the driving rod to move in the direction away from the collection platform. The movement of the driving rod drives the push plate to rotate around the connecting shaft, and the surface of the push plate is lifted and gradually tilted, so that the unqualified steel billets on the push plate slide to the surface of the conveyor belt. After the rejection is completed, the piston rod of the hydraulic cylinder extends, and the piston rod drives the push plate to reset so that the next rejection operation can be carried out smoothly. The rejection operation is automatically controlled by the hydraulic cylinder, which avoids the safety hazard caused by the high temperature of the steel billet to the workers.

[0010] Optionally, a protective baffle is provided on a side of the collecting platform away from the frame.

[0011] By adopting the above technical solution, under the protection of the protective block, unqualified steel billets will not directly slide out of the conveyor belt surface due to inertia, thereby increasing the probability that the conveyor belt will directly convey the unqualified steel billets out of the collection platform.

[0012] Optionally, a protective chamfer is provided between the protective baffle and the surface of the conveyor belt, and the protective chamfer is rounded.

[0013] By adopting the above technical solution, when the unqualified steel billet slides and contacts the protective baffle, the protective chamfer converts part of the kinetic energy of the rising steel billet into gravitational potential energy, thereby reducing the impact energy received by the protective baffle and increasing the service life of the protective baffle.

[0014] Optionally, a guide platform is provided on a side of the collecting platform close to the frame, and a guide slope is provided on the guide platform and is inclined from top to bottom along the frame toward the collecting platform.

[0015] By adopting the above technical solution, when the unqualified steel billet is about to slide onto the collection table, the guide slope on the guide table can smoothly transition the unqualified steel billet to the surface of the conveyor belt, reducing the vibration caused by the change in the movement direction of the steel billet, thereby reducing the possibility of the unqualified steel billet getting stuck between the push plate and the collection table, and ensuring the smooth progress of the rejection operation.

[0016] Optionally, a cooling assembly is provided on the collection table, and the cooling assembly includes a cooling box fixedly mounted on the bottom surface of the collection table, a liquid delivery pipe is connected to the cooling box, a liquid delivery pump is provided on the liquid delivery pipe, a plurality of grooves are provided on the protective baffle, a cavity connected to the plurality of grooves is provided on the protective baffle, one end of the liquid delivery pipe extends into the cavity and is connected to a connecting pipe, a liquid outlet pipe corresponding to the plurality of grooves is connected to the connecting pipe, the liquid outlet end of the liquid outlet pipe extends out of the groove and is connected to an atomizing nozzle, and the water outlet direction of the atomizing nozzle is set toward the conveyor belt.

[0017] By adopting the above technical solution, the liquid feeding pump is started at the time of rejection, and the liquid feeding pump draws the coolant in the cooling box into the liquid feeding pipe. The coolant flows into the liquid outlet pipe through the liquid feeding pipe and the connecting pipe, and is finally atomized by the atomizing nozzle to become cooling droplets sprayed on the surface of the steel billet. When the cooling droplets come into contact with the unqualified steel billet, they absorb the heat from the surface of the unqualified steel billet and eventually vaporize and evaporate. At this time, the surface temperature of the conveyed steel billet is reduced, reducing the risk of workers being burned due to contact with high-temperature steel rolling, and facilitating subsequent transportation, storage and further processing.

[0018] Optionally, sliders are provided at both opposite ends of the connecting tube, and a slide groove is provided on the inner side wall of the cavity for slidingly cooperating with the slider. The cross-sections of the slider and the slide groove are square, and a screw is rotatably connected in each of the slide grooves. The slider is threadedly connected to the screw, and one end of the screw extends out of the cavity and is fixedly connected to a pulley. A belt is jointly provided on the outside of the two pulleys, and a motor is provided on the protective baffle, and the output shaft of the motor is coaxially and fixedly connected to one of the screws.

[0019] By adopting the above technical solution, the motor is started in the process of the steel billet rolling down from the push plate, and the motor drives the two screws to rotate synchronously through the transmission action of the pulley and the belt. The rotation of the screw drives the slider to move in the direction away from the guide platform, and the movement of the slider drives the connecting pipe to move. The connecting pipe drives the atomizing nozzle to gradually move toward the groove through the liquid outlet pipe. At this time, the liquid outlet range of the atomizing nozzle changes as the steel billet moves toward the conveyor belt, thereby increasing the contact range between the surface of the unqualified steel billet and the coolant, thereby improving the cooling effect of the coolant.

[0020] Optionally, a plurality of mounting slots are provided on the protective baffle, a small fan is provided in each of the mounting slots, and an air outlet end of the small fan is arranged toward the surface of the conveyor belt.

[0021] By adopting the above technical solution, after the steel billet slides onto the conveyor belt, the air absorbs heat and the temperature rises. The airflow blown out by the fan can quickly take away the hot air and introduce air with lower temperature for heat exchange. At the same time, air cooling can promote the evaporation process of the coolant, thereby enhancing the overall cooling effect on the steel billet surface, shortening the cooling time and improving the cooling efficiency.

[0022] Optionally, a high-temperature resistant rubber layer is provided on the surface of the push plate.

[0023] By adopting the above technical solution, when the push plate contacts the unqualified steel billet, the setting of the high-temperature resistant rubber layer effectively buffers the impact force generated by the collision between the push plate and the unqualified steel billet, reduces the damage caused by the impact force to the steel billet and the push plate, and at the same time reduces the adverse effects of the high temperature of the steel billet on the push plate structure, thereby extending the service life of the push plate.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. This application provides a push plate and a rejection assembly. When unqualified billets appear, the rejection assembly drives the push plate to rotate, and the push plate pushes the unqualified billets from the surface of the conveyor roller to the conveyor belt. The conveyor belt then conveys the unqualified billets out of the collection platform. This arrangement enables the timely rejection of unqualified billets, preventing them from entering the intermediate rolling process, thereby improving the production quality of rolled steel.

[0026] 2. This application provides an atomizing nozzle and a small fan. The atomizing nozzle sprays coolant on the surface of unqualified steel billets. The small fan accelerates the evaporation rate of coolant droplets on the surface of the steel billets through air cooling. When the coolant droplets evaporate, they carry away the heat of the steel billet surface, thereby cooling the unqualified steel billets, reducing the risk of workers being burned by exposure to high-temperature steel rolling, and facilitating subsequent handling, storage, and further processing.

[0027] 3. This application sets a screw, a slider, a connecting pipe and a liquid outlet pipe. In the process of the steel billet sliding from the push plate to the surface of the conveyor belt, the rotation of the screw drives the liquid outlet pipe to move, and the liquid outlet pipe drives the atomizing nozzle to move. At this time, the liquid outlet range of the atomizing nozzle changes as the steel billet moves toward the conveyor belt, thereby increasing the contact range between the surface of the unqualified steel billet and the coolant.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] The embodiment of the present application discloses a rough intermediate roller removal device for steel rolling.

[0037] Reference Figure 1 and Figure 2 A steel rolling rough intermediate roller rejection device includes a frame 1, a plurality of drive motors 01 are fixedly installed on one side of the frame 1, and conveying rollers 02 corresponding to the plurality of drive motors 01 are rotatably connected to the frame 1. The plurality of conveying rollers 02 are evenly and equidistantly arranged in the length direction of the frame 1. The conveying rollers 02 are driven by the drive motor 01 to rotate and are responsible for conveying the steel billet from the rough rolling process to the intermediate rolling process.

[0038] Reference Figure 1 and Figure 2A collecting platform 2 is provided on the side of the frame 1 away from the driving motor 01. The collecting platform 2 is installed on the ground. A conveyor belt 3 for conveying unqualified steel billets is installed on the collecting platform 2. The conveying direction of the conveyor belt 3 is opposite to the conveying direction of the conveying roller 02 to avoid the accumulation of unqualified steel billets on the collecting platform 2. A connecting shaft 4 is fixedly connected to the side of the frame 1 close to the collecting platform 2. The axial extension direction of the connecting shaft 4 is parallel to the length direction of the frame 1. A plurality of equidistant and evenly distributed push plates 5 are rotatably connected to the connecting shaft 4. The push plate 5 includes a horizontal section 51 arranged horizontally and a vertical section 52 integrally formed with the horizontal section 51. The push plate 5 is located in the gap between two adjacent conveying rollers 02. A high-temperature resistant rubber layer is fixedly installed on the surface of the push plate 5. In this embodiment, the high-temperature resistant rubber layer is made of silicone rubber. The high-temperature resistant rubber layer effectively buffers the impact force generated when the steel billet collides with the push plate 5. A rejection component 6 is provided on the frame 1.

[0039] Reference Figure 1 and Figure 2 The rejection component 6 includes a hydraulic cylinder 61 corresponding to a plurality of push plates 5. The hydraulic cylinder 61 is fixedly mounted on the side of the frame 1 away from the collection table 2. The end of the piston rod of the hydraulic cylinder 61 is hinged with a drive rod 62. The end of the drive rod 62 away from the hydraulic cylinder 61 is hinged to the vertical section 52 of the push plate 5. When in the non-rejecting state, the piston rod of the hydraulic cylinder 61 is in an extended state, the height of the top surface of the push plate 5 is below the top surface of the conveying roller 02, and the length direction of the horizontal section 51 of the push plate 5 is parallel to the length direction of the conveying roller 02.

[0040] When unqualified steel billets appear, the piston rod of the hydraulic cylinder 61 retracts, and the piston rod drives the driving rod 62 to move in the direction away from the collecting platform 2. The movement of the driving rod 62 drives the push plate 5 to rotate upward around the connecting shaft 4 toward the collecting platform 2. When the push plate 5 rotates, it drives the steel billets to move upward and gradually forms an inclined slope. The unqualified steel billets roll along the inclined push plate 5 to the collecting platform 2, and the conveyor belt 3 transports the unqualified steel billets out of the collecting platform 2. Then the piston rod of the hydraulic cylinder 61 extends, and the piston rod belt drives the push plate 5 to reset through the driving rod 62 so that the next rejection operation can be carried out smoothly. This arrangement realizes the timely rejection of unqualified steel billets, prevents unqualified steel billets from entering the intermediate rolling process, and thus improves the production quality of steel rolling.

[0041] Reference Figure 2 and Figure 3The collecting table 2 is fixedly connected to a guide table 21 on one side close to the frame 1. The guide table 21 is provided with a guide slope 211 inclined from top to bottom along the direction of the frame 1 wire removal collecting table 2. When the push plate 5 is driven by the hydraulic cylinder 61 and tilted to the maximum extent, the inclination angle of the push plate 5 is the same as the inclination angle of the guide slope 211, and there is always no gap at the connection between the push plate 5 and the guide table 21 during this process. The setting of the guide table 21 and the guide slope 211 can smoothly transition the unqualified steel billets to the surface of the conveyor belt 3, reduce the vibration caused by the change in the movement direction of the steel billets, thereby reducing the possibility of the unqualified steel billets being stuck between the push plate 5 and the collecting table 2, and ensuring the smooth progress of the rejection operation.

[0042] Reference Figure 2 and Figure 3 A protective baffle 22 is fixedly connected to the side of the collecting platform 2 away from the guide platform 21. The protective baffle 22 is perpendicular to the surface of the conveyor belt 3. The length of the protective baffle 22 is the same as the length of the collecting platform 2. When unqualified steel billets slide onto the conveyor belt 3, the protective baffle 22 effectively prevents the steel billets from leaving the conveyor belt 3. A protective chamfer 221 is formed between the protective baffle 22 and the surface of the conveyor belt 3. The protective chamfer 221 is a rounded corner. When the unqualified steel billet slides and contacts the protective baffle 22, part of the kinetic energy of the unqualified steel billet is converted into gravitational potential energy due to the opening of the protective chamfer 221, thereby reducing the impact energy received by the protective baffle 22 and having a better deceleration effect.

[0043] Reference Figures 3 to 5 The collecting platform 2 is provided with a cooling assembly 7, which includes a cooling box 71 fixedly mounted on the bottom surface of the collecting platform 2. The cooling box 71 stores coolant, and a liquid delivery pipe 72 is connected to the cooling box 71. A liquid delivery pump 73 for delivering coolant is fixedly mounted on the liquid delivery pipe 72. A plurality of grooves 222 are provided on the surface of the protective baffle 22 facing the guide platform 21. The plurality of grooves 222 are evenly distributed in the length direction of the protective baffle 22. The protective baffle 22 is provided with a plurality of grooves 222. 2 is connected to the cavity 223, the liquid outlet end of the liquid feeding pipe 72 extends into the interior of the cavity 223 and is connected to a connecting pipe 74. The connecting pipe 74 is perpendicular to the liquid feeding pipe 72, and the length direction of the connecting pipe 74 is parallel to the length direction of the protective baffle 22. The connecting pipe 74 is connected to liquid outlet pipes 75 corresponding to the multiple grooves 222. The liquid outlet pipes 75 are arranged in correspondence with the corresponding grooves 222. The liquid outlet ends of the liquid outlet pipes 75 extend out of the grooves 222 to above the conveyor belt 3 and are connected to an atomizing nozzle 76.

[0044] Reference Figures 3 to 6The part of the liquid delivery pipe 72 extending to the cavity 223 is a bellows, and the two ends of the connecting pipe 74 parallel to the length direction are fixedly connected to the slider 8. A slide groove 9 is provided on the inner side wall of the cavity 223, which slides with the slider 8. The cross-sections of the slide groove 9 and the slider 8 are square to limit the relative rotation between the slide groove 9 and the slider 8. A screw 91 is rotatably connected in each slide groove 9, and one end of the screw 91 extends out of the cavity 223 and is fixedly connected to a pulley 10. The two pulleys 10 are rotatably arranged on the outer surface of the protective baffle 22. A belt 101 is commonly provided on the outside of the two pulleys 10. A motor 11 is fixedly mounted on the protective baffle 22, and the output shaft of the motor 11 is coaxially and fixedly connected to one of the screws 91.

[0045] During the rejection process, the motor 11 and the liquid feeding pump 73 are started, and the liquid feeding pump 73 draws the coolant in the cooling box 71 into the liquid feeding pipe 72. The coolant flows through the liquid feeding pipe 72 and the connecting pipe 74 to the liquid outlet pipe 75, and finally is atomized by the atomizing nozzle 76 to become coolant droplets sprayed on the surface of the billet. At the same time, when the billet slides down from the push plate 5, the motor 11 drives the two screws 91 to rotate synchronously through the transmission effect of the pulley 10 and the belt 101. The rotation of the screw 91 drives the slider 8 to move in the direction away from the guide platform 21, and the slider 8 moves The connecting pipe 74 is driven to move, and the connecting pipe 74 drives the atomizing nozzle 76 to gradually move toward the groove 222 through the liquid outlet pipe 75. At this time, the liquid outlet range of the atomizing nozzle 76 changes as the billet moves toward the conveyor belt 3, thereby increasing the contact range between the surface of the unqualified billet and the coolant. When the coolant droplets come into contact with the unqualified billet, they absorb the heat from the surface of the unqualified billet and eventually vaporize and evaporate. At this time, the surface temperature of the conveyed billet is lowered, reducing the risk of workers being burned by contact with high-temperature steel rolling, and facilitating subsequent transportation, storage and further processing.

[0046] Reference Figures 3 to 6 A plurality of mounting grooves 224 are provided on the protective baffle 22, and the plurality of mounting grooves 224 are evenly distributed along the length direction of the protective baffle 22. A small fan 12 is fixedly installed in each mounting groove 224, and the air outlet end of the small fan 12 is arranged toward the surface of the conveyor belt 3.

[0047] After the billet slides onto the conveyor belt 3, the air absorbs heat and its temperature rises. The airflow blown out by the fan can quickly take away the hot air and introduce air with lower temperature for heat exchange. At the same time, air cooling can promote the evaporation process of the coolant, thereby enhancing the overall cooling effect on the billet surface, shortening the cooling time and improving the cooling efficiency.

[0048] The implementation principle of the rough intermediate roller rejection device for steel rolling in the embodiment of the present application is as follows: the conveying roller 02 conveys the steel billet that has undergone rough rolling to the intermediate rolling process. When unqualified steel billets appear, the control system controls the piston rod of the hydraulic cylinder 61 to retract, and the piston rod drives the driving rod 62 to move in the direction away from the collection platform 2. The driving rod 62 moves and drives the push plate 5 to rotate upward around the connecting shaft 4 toward the collection platform 2. When the push plate 5 rotates, it drives the steel billet to move upward and gradually forms an inclined surface. The unqualified steel billet rolls along the inclined push plate 5 to the collection platform 2, and the conveyor belt 3 transports the unqualified steel billet out of the collection platform 2. Then the piston rod of the hydraulic cylinder 61 is extended, and the piston rod belt drives the push plate 5 to reset through the driving rod 62 so that the next rejection operation can be carried out smoothly. This arrangement realizes the timely rejection of unqualified steel billets, prevents unqualified steel billets from entering the intermediate rolling process, and thus improves the production quality of steel rolling.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
