Description

Technical Field

[0001] This utility model belongs to the field of descaling technology in the roughing zone, and specifically relates to an automated steam and water descaling device for the roughing zone of N08926 iron-nickel-based alloy hot continuous rolling coil. Background Technology

[0002] Iron-nickel based alloy N08926 is a high-performance alloy material. Its chemical composition is based on iron and nickel, with the addition of alloying elements such as chromium, molybdenum, copper, and nitrogen, forming a unique microstructure that combines high strength, excellent corrosion resistance, and good high-temperature mechanical properties. Due to its good corrosion resistance and high-temperature performance, nickel-based alloy N08926 is widely used in aerospace, chemical, petrochemical, and nuclear energy fields.

[0003] During the roughing process, the surface of the iron-nickel based alloy N08926 is exposed to newly formed secondary oxide scale due to high temperature. It is necessary to clean the surface with high-temperature steam and water. At the same time, when the roughing mill rolls the surface of the iron-nickel based alloy N08926, some oxide scale will stick to the surface of the roughing rolls. If it is not cleaned in time, it will not only lead to accelerated wear of the roughing rolls, but also cause defects such as indentations and scratches on the surface of the plate, reducing the product quality of the plate surface.

[0004] A search revealed a high-formability duplex stainless steel sheet hot continuous rolling apparatus (CN222568772U), comprising a conveyor roller, a roughing rolling mechanism, a collecting mechanism, and a first descaling mechanism. The collecting mechanism includes a surrounding plate and a holding assembly, with the surrounding plate connected to the holding assembly and the holding assembly installed on the side of the roughing rolling mechanism. The first descaling mechanism includes a first water tank and a descaling assembly, with the first water tank connected to the holding assembly and the descaling assembly connected to the holding assembly. The second descaling mechanism includes a second water tank and a spraying assembly, with the second water tank installed between the roughing rolling mechanism and the finishing rolling mechanism and the second water tank connected to the spraying assembly. The spraying assembly is connected to both the roughing rolling mechanism and the finishing rolling mechanism.

[0005] A further search revealed that the existing technology announcement number is CN219401700U, which describes a hot continuous rolling device for corrosion-resistant stainless steel-carbon steel composite plates. This device includes a heating furnace, a descaling machine, a roughing mill, a finishing mill, and a coiler. The roughing mill includes a roughing mechanism, a descaling mechanism, and a temperature shield. A descaling mechanism is located on one side of the roughing mechanism. The descaling mechanism has several temperature shields. The descaling mechanism includes a support box, a temperature shield, a square opening, a limiting plate, a sliding frame, an annular gear disc, a first gear, a first motor, a rack, a limiting block, a second motor, a motor base, a high-pressure water pipe, a high-pressure nozzle, a moving frame, a third motor, a rotating disc, a swing rod, a swing frame, a fixed block, and an adjustment mechanism. A square opening is located on one side of the temperature shield.

[0006] Neither of the two existing technologies mentioned above cleans the residual oxide scale adhering to the rolling rolls when descaling stainless steel plates. If the residual oxide scale adheres to the surface of the rolls for a long time, it will not only lead to increased wear of the rolls, but also cause defects such as indentations and scratches on the surface of the plate, reducing the product quality of the plate surface, and thus adversely affecting the subsequent processing and finished product performance of the stainless steel plate. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automated steam and water descaling device for the roughing zone of N08926 iron-nickel-based alloy hot-rolled coils. By adjusting the spraying mechanism and the cleaning mechanism simultaneously, the cleaning of the surface of the hot-rolled coils and the surface of the roughing rolls is achieved, reducing the risk of defects such as indentations and scratches on the surface of the plate and ensuring the surface quality of the hot-rolled coils.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The spraying mechanism is used to clean the oxide scale on the surface of the iron-nickel-based alloy hot-rolled coil, and the cleaning mechanism is used to clean the oxide scale adhering to the surface of the roughing rolls.

[0010] The adjustment mechanism includes a mounting shell, a mounting frame, a connecting rod, a sliding block, a double-acting screw, a motor I, and a sliding rod. The mounting frame is installed between two sets of roughing rolling mechanisms. Sliding grooves II are provided on both sides of the mounting frame. Two sets of mounting shells are respectively installed on both sides of the mounting frame. Sliding grooves I are provided at both the upper and lower ends of the mounting shells. Sliding frames are provided at both the upper and lower ends of the two sets of mounting shells. The sliding frames are slidably connected to the mounting frame through the sliding grooves II. The sliding frames on both sides of the mounting frame are connected through a spraying mechanism and a cleaning mechanism. Two sets of sliding blocks are slidably installed inside the mounting shell. The upper and lower ends of the sliding blocks pass through the sliding grooves I and are hinged to the connecting rod. The connecting rod is hinged to the sliding frame. The double-acting screw is rotatably installed in one set of mounting shells, and the sliding rod is installed in the other set of mounting shells. The motor I is installed at one end of the double-acting screw, and the output shaft of the motor I is fixedly connected to the double-acting screw. The double-acting screw is threadedly connected to the sliding block, and the sliding rod is slidably connected to the sliding block.

[0011] The spraying mechanism includes a telescopic tube, a sleeve, a rotating tube, and a stepper motor I. A rotating tube is located between the sliding frames on both sides of the mounting frame. A nozzle is located at the bottom of the rotating tube. One end of the rotating tube is rotatably connected to the telescopic tube via the sleeve. The telescopic end of the telescopic tube is fixedly connected to the sliding frame and the mounting frame. The other end of the rotating tube is provided with a protective shell I, which is fixedly connected to the sliding frame. A gear is provided on the portion of the rotating tube rotatably connected to and located inside the protective shell I. The stepper motor I is mounted on the sliding frame. The output shaft of the stepper motor I passes through the protective shell I and is equipped with a gear. The gear on the output shaft of the stepper motor I meshes with the gear at the end of the rotating tube.

[0012] The cleaning mechanism includes a sludge collection shell, a protective shell II, an electric push rod, a connecting plate, a rotating shaft, a scraper, a motor II, and a lead screw. A fixed shell is provided between the sliding frames on both sides of the mounting frame. The fixed shell is located on both sides of the rotating tube. Two sets of protective shells II are installed inside the fixed shell. The electric push rod is installed inside the protective shell II, and its telescopic end passes through the protective shell II and is fixedly connected to the connecting plate. The connecting plate is hinged to the sludge collection shell via the rotating shaft, which is also fixedly connected to the sludge collection shell. One end of the connecting plate has a protective shell III, which passes through the protective shell III and has a limiting groove.

The motor II is installed inside the protective shell III, and the bevel gear on the output shaft of the motor II meshes with the bevel gear at the bottom end of the lead screw. The scraper is slidably connected to the sludge collection shell.

[0013] A spring is provided at the connection between the scraper and the sludge collection shell. A telescopic rod is sleeved inside the spring. The scraper is connected to the sludge collection shell through the telescopic rod. The spring plays a buffering role when the scraper encounters hard objects while cleaning the surface of the coarse roller, preventing the scraper from being damaged by hard scraping and reducing the service life of the scraper.

[0014] The sludge collection shell has a suction port on one side.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1) Motor I drives the bidirectional lead screw to rotate, causing two sets of sliding blocks to slide within the mounting housing. As the sliding blocks slide, the sliding frame moves up and down within the sliding groove II of the mounting frame via the hinged connecting rod, thereby synchronously adjusting the height and position of the spraying mechanism and cleaning mechanism mounted on the sliding frame. Stepper motor I drives the rotating tube to swing, causing the spray head to rotate at multiple angles and expanding the cleaning range of the spray head. Two sets of electric push rods extend simultaneously, pushing the connecting plate to bring the scraper closer to the roughing roll. Motor II drives the lead screw to rotate, and the lead screw drives the gear to rotate through the threaded rack, causing the rotating shaft to rotate and adjusting the scraper angle so that the scraper fits against the surface of the roughing roll. This achieves synchronous and efficient cleaning of the surface of the hot-rolled iron-nickel alloy coil and the roughing roll, reducing the risk of defects such as indentations and scratches on the surface of the plate and ensuring the surface quality of the hot-rolled iron-nickel alloy coil.

[0026] To facilitate understanding by those skilled in the art, the following is a detailed explanation in conjunction with the appendix. Figure 1-8 The technical solution of this utility model will be further described in detail below.

[0027] An automated steam-water descaling device for the roughing zone of N08926 iron-nickel-based alloy hot-rolled coil includes a roughing mechanism 1, roughing rolls 101, a sludge collection box 104, an adjusting mechanism 2, a spraying mechanism 3, and a cleaning mechanism 4. The roughing mechanism 1 has two sets, and roughing rolls 101 are installed on the roughing mechanism 1. A transport frame 102 is provided on one side of the roughing mechanism 1, and a transport roll 103 is provided on the transport frame 102. A sludge collection box 104 is installed at the bottom between the two sets of roughing mechanisms 1. The adjusting mechanism 2 is installed between the two sets of roughing mechanisms 1. The spraying mechanism 3 and the cleaning mechanism 4 are installed on the adjusting mechanism 2. The cleaning mechanism 4 is located on both sides of the spraying mechanism. The spraying mechanism 3 is used to clean the oxide scale on the surface of the iron-nickel-based alloy hot-rolled coil, and the cleaning mechanism 4 is used to clean the oxide scale adhering to the surface of the roughing rolls 101.

[0028] As described above, the hot-rolled iron-nickel alloy coil is fed into the roughing mill 1 by the transport rollers 103 on the transport frame 102 for rolling. When the hot-rolled iron-nickel alloy coil is rolled between the roughing mills 1, the adjusting mechanism 2 adjusts the position of the spraying mechanism 3 and the cleaning mechanism 4. The spraying mechanism 3 sprays a mixture of high-temperature steam and water to powerfully remove the oxide scale from the surface of the coil. The peeled oxide scale falls into the bottom collection box 104. At the same time, the cleaning mechanism 4 operates synchronously to scrape and clean the oxide scale adhering to the surface of the roughing rollers 101, so as to avoid the oxide scale residue affecting the rolling quality.

[0029] The adjusting mechanism 2 includes a mounting shell 21, a mounting frame 22, a connecting rod 24, a sliding block 25, a double-acting lead screw 26, a motor I 27, and a sliding rod 28. The mounting frame 22 is installed between the two sets of roughing rolling mechanisms 1. Sliding grooves II 2201 are provided on both sides of the mounting frame 22. The two sets of mounting shells 21 are respectively installed on both sides of the mounting frame 22. Sliding grooves I 2101 are provided at both the upper and lower ends of the mounting shells 21. Sliding frames 23 are provided at both the upper and lower ends of the two sets of mounting shells 21. The sliding frames 23 are slidably connected to the mounting frame 22 through the sliding grooves II 2201. The sliding frames 23 on both sides of the mounting frame 22 are connected to the mounting frame 22 through the sliding grooves II 2201. The spraying mechanism 3 and the cleaning mechanism 4 are connected. Two sets of sliding blocks 25 are slidably installed in the mounting shell 21. The upper and lower ends of the sliding blocks 25 pass through the sliding groove I 2101 and are hinged to the connecting rod 24. The connecting rod 24 is hinged to the sliding frame 23. The bidirectional screw 26 is rotatably installed in one set of mounting shells 21, and the sliding rod 28 is installed in the other set of mounting shells 21. The motor I 27 is installed at one end of the bidirectional screw 26. The output shaft of the motor I 27 is fixedly connected to the bidirectional screw 26. The bidirectional screw 26 is threadedly connected to the sliding block 25, and the sliding rod 28 is slidably connected to the sliding block 25.

[0030] As described above, motor I 27 drives the bidirectional lead screw 26 to rotate, causing the two sets of sliding blocks 25 to slide within the mounting housing 21. When the sliding blocks 25 slide, the sliding frame 23 is driven to slide up and down within the sliding groove II 2201 of the mounting frame 22 via the hinged connecting rod 24. This, in turn, drives the spraying mechanism 3 and the cleaning mechanism 4 mounted on the sliding frame 23 to adjust their height and position synchronously, achieving precise alignment of the hot-rolled iron-nickel alloy coil and the roughing roll 101, providing flexible and stable support for descaling and cleaning operations.

[0031] The spraying mechanism 3 includes a telescopic tube 31, a sleeve 32, a rotating tube 33, and a stepper motor I 36; a rotating tube 33 is provided between the sliding frames 23 on both sides of the mounting frame 22, and a nozzle 34 is provided at the bottom of the rotating tube 33. One end of the rotating tube 33 is rotatably connected to the telescopic tube 31 through the sleeve 32. The telescopic end of the telescopic tube 31 is fixedly connected to the sliding frame 23 and the mounting frame 22. The other end of the rotating tube 33 is provided with a protective shell I 35, which is fixedly connected to the sliding frame 23. The part of the rotating tube 33 that is rotatably connected to the protective shell I 35 and located inside the protective shell I 35 is provided with a gear. The stepper motor I 36 is mounted on the sliding frame 23. The output shaft of the stepper motor I 36 passes through the protective shell I 35 and is provided with a gear. The gear on the output shaft of the stepper motor I 36 meshes with the gear at the end of the rotating tube 33.

[0032] As described above: after the adjusting mechanism 2 moves the sliding frame 23 to a suitable position, the telescopic tube 31 adjusts its length as the sliding frame 23 moves; the stepper motor I 36 drives the rotating tube 33 to swing, causing the nozzle 34 to rotate at multiple angles, thus expanding the cleaning range of the nozzle 34; high-temperature steam and water enter the rotating tube 33 through the telescopic tube 31 and the sleeve 32, and are sprayed out from the nozzle 34 to clean the oxide scale on the surface of the plate coil in an all-round and efficient manner, ensuring the descaling effect.

[0033] The cleaning mechanism 4 includes a sludge collection shell 41, a protective shell II 42, an electric push rod 43, a connecting plate 44, a rotating shaft 46, a scraper 48, a motor II 410, and a lead screw 412. A fixed shell 45 is provided between the sliding frames 23 on both sides of the mounting bracket 22. The fixed shell 45 is located on both sides of the rotating tube 33. Two sets of protective shells II 42 are installed inside the fixed shell 45. The electric push rod 43 is installed inside the protective shell II 42. The telescopic end of the electric push rod 43 passes through the protective shell II 42 and is fixedly connected to the connecting plate 44. The connecting plate 44 is hinged to the sludge collection shell 41 via the rotating shaft 46, and the rotating shaft 46 is fixedly connected to the sludge collection shell 41. 4. One end of the connecting plate 44 is provided with a protective shell Ⅲ47. One end of the connecting plate 44 passes through the protective shell Ⅲ47 and is provided with a limiting groove 4401. One end of the rotating shaft 46 passes through the protective shell Ⅲ47 and is provided with a gear. A rack is provided on one side of the gear. The gear meshes with the rack, and the rack is slidably connected to the connecting plate 44 through the limiting groove 4401. The lead screw 412 is rotatably installed in the protective shell Ⅲ47. The lead screw 412 is threadedly connected to the rack, and a bevel gear is provided at the bottom end of the lead screw 412. The motor Ⅱ410 is installed in the protective shell Ⅲ47. The bevel gear on the output shaft of the motor Ⅱ410 meshes with the bevel gear at the bottom end of the lead screw 412. The scraper 48 is slidably connected to the sludge collection shell 41.

[0034] A spring 413 is provided at the connection between the scraper 48 and the sludge collection shell 41. A telescopic rod is sleeved inside the spring 413. The scraper 48 is connected to the sludge collection shell 41 through the telescopic rod. The spring 413 plays a buffering role when the scraper 48 encounters hard objects while cleaning the surface of the coarse roller 101, preventing the scraper 48 from being damaged by hard scraping and reducing the service life of the scraper 48.

[0035] The sludge collection shell 41 is provided with a suction port 49 on one side;

[0036] The motor terminals of the two sets of electric actuators 43 are directly connected in parallel to the same controller. The controller outputs the same signal to control the speed of the motors of the two sets of electric actuators 43, thereby synchronously controlling the extension and retraction speed of the two sets of electric actuators 43.

[0037] As described above, after the adjusting mechanism 2 moves the sliding frame 23 to a suitable position, the two sets of electric push rods 43 extend simultaneously, pushing the connecting plate 44 to bring the scraper 48 closer to the roughing roll 101; the motor II 410 drives the lead screw 412 to rotate, and the lead screw 412 drives the gear to rotate through the threaded rack, causing the rotating shaft 46 to rotate, adjusting the angle of the scraper 48 so that the scraper 48 fits against the surface of the roughing roll 101, and the peeled oxide scale falls into the sludge collection shell 41 and is sucked away through the suction port 49, ensuring the surface of the roughing roll 101 is clean and maintaining the rolling accuracy.
