Description

Technical Field

[0001] This invention relates to the field of hot-dip galvanized steel coil production technology, and in particular to a fully automated hot-dip galvanized steel coil production system and production method. Background Technology

[0002] Steel is prone to rusting in air and water, while zinc corrodes at only one-fifteenth the rate of steel in the atmosphere. To effectively protect steel sheets from corrosion, galvanized steel sheets achieve protection through a dense zinc coating. Steel strip, a narrow and long steel plate made of carbon steel, is widely used not only as a traction and transport component in belt conveyors but also for cargo bundling. These products are meticulously manufactured by steel rolling mills to meet the needs of various industrial sectors in the manufacture of metal or machinery products. Steel strip, also known as strip steel, is limited to a width of 1300 mm, while its length varies depending on the specific coil. Strip steel is typically supplied in coils and features high dimensional accuracy, a superior surface finish, ease of processing, and material savings.

[0003] However, current strip coiling mechanisms lack automatic unwinding capabilities after coiling, making it difficult to automatically unload the coiled strip. This necessitates manual operation, reducing efficiency and consuming significant labor, thus impacting practicality. Furthermore, existing strip coiling mechanisms require manual pushing of a transport vehicle to move the coil after coiling, failing to achieve fully automated coiling and transport, further reducing practicality and efficiency. While existing technologies may already address these issues, this paper aims to provide an alternative or replacement solution. Summary of the Invention

[0004] The technical solution of the present invention to achieve the above objectives is as follows: a fully automatic production method for hot-dip galvanized steel coils, comprising the following steps: step S1, uncoiling and initial processing; step S2, deep cleaning; step S3, annealing and cooling; step S4, hot-dip galvanizing; step S5, cooling and air drying; step S6, leveling and tensioning; step S7, post-galvanizing anti-corrosion treatment.

[0005] Step S1: First, the cold-rolled steel coil is uncoiled, and then an advanced shearing and welding machine is used for precise shearing and efficient welding to ensure that the initial processing of the material meets the requirements of subsequent production.

[0006] Step S2: After a second chemical degreasing process, the surface of the steel plate is thoroughly cleaned to ensure that there is no oil or impurities on the plate surface, laying a solid foundation for subsequent process steps.

[0007] Step S3: The steel plate then enters the annealing furnace for continuous annealing treatment. This process helps to eliminate internal stress in the material and improve the machinability and mechanical properties of the plate.

[0008] Step S4: The steel plate is placed in a zinc pot for hot-dip galvanizing. This step aims to give the steel plate excellent corrosion resistance and aesthetics, ensuring that it can maintain a long service life under various environmental conditions.

[0009] Step S5: After galvanizing, the steel plate enters the quenching tank for rapid cooling and is dried by air drying equipment to remove excess moisture from the surface, preparing it for the next step of processing.

[0010] Step S6: The steel plate enters the leveling machine and undergoes finishing and tension straightening to ensure that the plate surface is flat and free of warping, meeting the requirements of high-precision processing.

[0011] Step S7: The steel plate enters the passivation device for post-plating anti-corrosion treatment. Through a specific chemical treatment process, the corrosion resistance of the steel plate is further improved, ensuring that it is not easily damaged during long-term use.

[0012] In step S3, after annealing, the steel plate will undergo a cooling stage to ensure that the temperature drops to a suitable level.

[0035] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in the order of operation. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0036] Example

[0037] A fully automated production method for hot-dip galvanized steel coils includes the following steps: Step S1, uncoiling and initial processing; Step S2, deep cleaning; Step S3, annealing and cooling; Step S4, hot-dip galvanizing; Step S5, cooling and air drying; Step S6, leveling and tensioning; Step S7, post-galvanizing anti-corrosion treatment.

[0038] Step S1: First, the cold-rolled steel coil is uncoiled, and then an advanced shearing and welding machine is used for precise shearing and efficient welding to ensure that the initial processing of the material meets the requirements of subsequent production.

[0039] Step S2: After a second chemical degreasing process, the surface of the steel plate is thoroughly cleaned to ensure that there is no oil or impurities on the plate surface, laying a solid foundation for subsequent process steps.

[0040] Step S3: The steel plate then enters the annealing furnace 2 for continuous annealing treatment. This process helps to eliminate internal stress in the material and improve the machinability and mechanical properties of the plate.

[0041] Step S4: The steel plate is placed in a zinc pot for hot-dip galvanizing. This step aims to give the steel plate excellent corrosion resistance and aesthetics, ensuring that it can maintain a long service life under various environmental conditions.

[0042] Step S5: After galvanizing, the steel plate enters the quenching tank for rapid cooling and is dried by air drying equipment to remove excess moisture from the surface, preparing it for the next step of processing.

[0043] Step S6: The steel plate enters the leveling machine 5 and undergoes finishing and straightening to ensure that the plate surface is flat and free of warping, meeting the requirements of high-precision processing.

[0044] Step S7: The steel plate enters the passivation device for post-plating anti-corrosion treatment. Through a specific chemical treatment process, the corrosion resistance of the steel plate is further improved, ensuring that it is not easily damaged during long-term use.

[0045] In step S3, after annealing, the steel plate will undergo a cooling stage to ensure that the temperature drops to a suitable level.

[0046] like Figure 1-6 As shown, the degreasing concave box 1, the annealing furnace 2, the galvanizing box 3, the quenching and drying box 4, the leveling machine 5, the electroplating and anti-corrosion box 6, and the cleaning and drying box 7 are interconnected by a number of auxiliary kit brackets 8. The flow guiding structure 9 is connected to a number of auxiliary kit shaft tubes. The extrusion and conveying structure 10 and the stirring auxiliary structure 11 are installed on the degreasing concave box 1, the galvanizing box 3, the quenching and drying box 4, the electroplating and anti-corrosion box 6, and the cleaning and drying box 7.

[0047] Specifically, the diversion structure 9 includes: a pair of feeding hydraulic chucks 101, a concave feeding support block 102, a moving support block 103, a collecting support block 104, a pair of moving lead screw modules 105, a collecting drive shaft tube 106, several collecting sleeve arc blocks 107, a collecting drive inner shaft 108, several transmission pins 109, a pair of collecting gearboxes 110, a pair of collecting drive motors 111, a diversion and unloading assembly, and a compression limiting assembly;

[0048] Specifically, the concave feeding support block 102 is installed on the degreasing concave box 1, a pair of feeding hydraulic chucks 101 are installed on the concave feeding support block 102, the collecting support block 104 is installed on the cleaning and drying box 7, a pair of moving screw modules 105 are installed in parallel on the cleaning and drying box 7, the moving support block 103 is installed on the moving end of the pair of moving screw modules 105, the collecting drive shaft tube 106 is inserted into the collecting support block 104, a plurality of collecting sleeve arc blocks 107 are evenly installed on the collecting drive shaft tube 106, and the extrusion limiting component is installed on a plurality of collecting sleeve arc blocks. On block 107, the diversion and unloading assembly is installed on several of the collection kit arc blocks 107, the collection drive inner shaft 108 is inserted into the movable support block 103, several pin slots are opened on the outer side of the collection drive inner shaft 108 and the inner side of the collection drive shaft tube 106, several transmission pins 109 are movably inserted into the inner side of the pin slots on the collection drive inner shaft 108 and the collection drive shaft tube 106, a pair of collection gearboxes 110 are fitted on the collection drive shaft tube 106 and the collection drive inner shaft 108, and the drive ends of a pair of collection drive motors 111 are respectively connected to a pair of collection gearboxes 110;

[0049] It should be noted that, in the above process, the cold-rolled steel coil is uncoiled and then precisely sheared and efficiently welded using an advanced integrated shearing and welding machine. This ensures that the initial processing of the material meets the requirements of subsequent production. The welded steel plate is guided to the inside of the degreasing concave box 1 by the flow-guiding structure 9 and the extrusion and conveying structure 10. The raw materials inside the degreasing concave box 1 are mixed and stirred by the stirring auxiliary structure 11, thereby accelerating the degreasing reaction. Through airflow stirring, the thickness of the liquid film on the solid surface can be significantly reduced, making it easier for the degreasing agent to contact and act on the dirt. The stronger the stirring, the thinner the liquid film, and the larger the contact area between the degreasing agent and the dirt, thereby improving the degreasing efficiency. Stirring helps the dissolved dirt leave the metal surface, allowing new cleaning agent to occupy the surface, so that the metal surface can achieve a better cleaning effect. Stirring can break the relatively stable liquid film on the solid surface, making it easier for dirt to be washed away. Stirring helps the cleaning agent to be evenly distributed in the degreasing liquid, ensuring that each part is thoroughly cleaned. This not only improves the degreasing effect but also avoids excessive consumption of cleaning agents in a certain area. The chemical degreasing process thoroughly cleans the steel plate surface, ensuring it is free of oil and impurities, laying a solid foundation for subsequent processes. The steel plate then enters annealing furnace 2 for continuous annealing, a process that helps eliminate internal stress and improves the plate's machinability and mechanical properties. Next, the steel plate undergoes hot-dip galvanizing in a zinc bath; this step aims to give the steel plate excellent corrosion resistance and aesthetics, ensuring a long service life under various environmental conditions. After galvanizing, the steel plate enters a quenching tank for rapid cooling and is dried to remove excess moisture, preparing it for the next step. The steel plate then enters a leveling machine 5 for finishing and straightening to ensure a flat, warp-free surface, meeting high-precision processing requirements. Finally, the steel plate enters a passivation unit for post-galvanizing anti-corrosion treatment, using specific chemical... The processing technology further improves the corrosion resistance of the steel plate, ensuring that it is not easily damaged during long-term use. A pair of feeding hydraulic chucks 101 limit the steel coil, while a pair of collecting drive motors 111 operate, driving a pair of collecting gearboxes 110 on the drive end of the collecting drive motors 111. The collecting drive inner shaft 108 and collecting drive tube 106 inside the collecting gearboxes 110 rotate. At the same time, the collecting drive inner shaft 108 drives several guide pins 109 on it, which in turn drive the collecting drive tube 106 on its outer side to rotate. The collecting drive tube 106 drives several collecting sleeve arc blocks 107 on it. The expansion of the extrusion limiting components on the collection sleeve arc blocks 107 achieves the internal expansion, extrusion, and fixation of the steel coil, as well as vertical lifting, extrusion, and fixation collection.

[0050] like Figure 1-6As shown, the extrusion limiting assembly includes: a pair of extrusion concave blocks 201, a pair of extrusion convex blocks 202, a pair of lifting extrusion rods 203, a pair of extrusion limiting shafts 204, a pair of adsorption ring electromagnets 205, a pair of adsorption ring magnets 206, a pair of extrusion sleeve springs 207, several convex extension blocks 208, several arc extension blocks 209, several extension magnets 210, several extension metal rods 211, and extension electromagnets 212;

[0051] Specifically, a pair of extrusion concave blocks 201 are respectively mounted on the movable support block 103 and the collection support block 104; a pair of extrusion convex blocks 202 are respectively movably inserted into the inner side of the pair of extrusion concave blocks 201; a pair of extrusion limiting shafts 204 are respectively inserted into the pair of extrusion concave blocks 201, and the pair of extrusion limiting shafts 204 are respectively movably inserted into the pair of extrusion convex blocks 202; a pair of extrusion sleeve springs 207 are respectively sleeved on the pair of extrusion limiting shafts 204; a pair of adsorption ring electromagnets 205 are respectively mounted on the pair of extrusion concave blocks 201; a pair of adsorption ring magnets 206 are respectively mounted on the pair of extrusion convex blocks 202; and several collection sleeves... The arc block 107 is provided with convex expansion slots. A plurality of convex expansion blocks 208 are movably inserted into the inner side of the plurality of convex expansion slots. A plurality of arc expansion blocks 209 are installed on the plurality of convex expansion blocks 208.

A pair of lifting extrusion rods 203 are inserted into a pair of extrusion convex blocks 202.

[0052] It should be noted that, as described above, a pair of compression springs 207 respectively drive the compression convex blocks 202 on them, causing the pair of compression convex blocks 202 to rise and fall stably and vertically along the inner side of a pair of compression concave blocks 201. Simultaneously, the pair of compression convex blocks 202 drive the lifting compression rods 203 on them, which in turn compress and limit the rotating and collected steel coil. The compression limiting shaft 204 also limits the rise and fall of the compression convex blocks 202. Meanwhile, a pair of adsorption ring electromagnets 205 on the pair of compression concave blocks 201 are energized, causing them to magnetically attract a pair of adsorption ring magnets 206, thereby achieving the goal of moving the pair of compression convex blocks 202 along the inner side of the compression concave blocks 201. The inner side of 01 is stably raised and lowered to compress and fix or loosen the steel coil. At the same time, the extension electromagnet 212 is energized, and the extension electromagnet 212 transmits magnetism to several extension metal rods 211. The extension metal rods 211 magnetically repel several convex extension blocks 208. The convex extension blocks 208 drive the arc extension blocks 209 on them. The arc extension blocks 209 expand and fix the steel coil on the inner side, thereby achieving compression and fixation on both the inner and outer sides. The operation of a pair of movable screw modules 105 drives the movable support block 103 on it to move horizontally. The movable support block 103 causes the collecting drive inner shaft 108 on it to move horizontally stably, thereby exposing the steel coil.

[0053] like Figure 1-6 As shown, the discharge assembly includes: a discharge longitudinal and transverse screw module 301, a pair of discharge winches 302, a discharge plate 303, a pair of concave extrusion blocks 304, a pair of discharge extrusion screw modules 305, a pair of extrusion discharge hydraulic push rods 306, a pair of extrusion discharge plates 307 and 303, and a pair of extrusion discharge rubber blocks 308.

[0055] It should be noted that, as described above, the operation of the unloading longitudinal and transverse screw module 301 drives the operation of a pair of unloading winches 302 on it. The operation of the pair of unloading winches 302 drives the unloading plate 303 on it to rise and fall. At the same time, the operation of a pair of opposing unloading extrusion screw modules 305 on the unloading plate 303 drives a pair of concave extrusion blocks 304 on it. The pair of concave extrusion blocks 304 are inserted into the inside of the steel coil. The extension and retraction of the extrusion unloading hydraulic push rod 306 on the inside of the pair of concave extrusion blocks 304 drives the extrusion unloading plate 307303 on the pushing end of the extrusion unloading hydraulic push rod 306. The extrusion unloading plate 307303 drives the extrusion unloading rubber block 308 on it, thereby achieving the extrusion and fixing of the steel coil.

Springs 403 are respectively fitted onto several lifting limit shafts 402, several toothed metal rods 404 are respectively inserted into several auxiliary mounting brackets 8, and several toothed metal rods 404 are respectively connected to several lifting extrusion grooves, several repulsion electromagnets 405 are respectively installed on several toothed metal rods 404, several repulsion magnets 406 are respectively installed on several extrusion lifting L-shaped bearing blocks 401, and several extrusion rollers 407 are respectively installed on several extrusion lifting L-shaped bearing blocks 401;

[0058] It should be noted that, in the above process, several repulsive electromagnets 405 are energized, and the magnetism of the several repulsive electromagnets 405 is transferred to several toothed metal rods 404. The magnetism of the several toothed metal rods 404 is transferred to several repulsive magnets 406. The several repulsive magnets 406 drive the pressing and lifting L-shaped bearing blocks 401 on them. The pressing and lifting L-shaped bearing blocks 401 move stably up and down along the inner side of the pressing groove. At the same time, the pressing and lifting L-shaped bearing blocks 401 drive the pressing rollers 407 on them. The pressing rollers 407 press the steel coil into the inner side of the degreasing concave box 1, galvanizing box 3, quenching and drying box 4, electroplating and anti-corrosion box 6, and cleaning and drying box 7.

[0059] like Figure 1-6 As shown, the stirring auxiliary structure 11 includes: a plurality of L-shaped flow-guiding stirring tubes 501, a plurality of threaded inner blades 502, a plurality of toothed flow-guiding tubes 503, a plurality of negative pressure boxes 504, a plurality of negative pressure drive motors 505, a plurality of negative pressure gearboxes 506, a plurality of negative pressure threaded rods 507, a plurality of negative pressure tension plates 508, and a plurality of negative pressure threaded tubes 509.

[0060] Specifically, several L-shaped flow-guiding and stirring tubes 501 are respectively inserted in parallel into the degreasing concave box 1, the galvanizing box 3, the quenching and drying box 4, the electroplating and anti-corrosion box 6, and the cleaning and drying box 7. Several threaded inner blades 502 are respectively installed on the inner side of several L-shaped flow-guiding and stirring tubes 501. Several toothed flow-guiding tubes 503 are respectively connected to several L-shaped flow-guiding and stirring tubes 501. Several negative pressure boxes 504 are respectively connected to several toothed flow-guiding tubes 501. 3. Several negative pressure threaded tubes 509 are respectively inserted into several negative pressure boxes 504, several negative pressure threaded rods 507 are respectively movably inserted into the inner side of several negative pressure threaded rods 507 tubes, several negative pressure tension plates 508 are respectively installed on several negative pressure threaded rods 507, several negative pressure deflectors are respectively fitted onto several negative pressure threaded tubes 509, and the driving ends of several negative pressure drive motors 505 are respectively connected to several negative pressure gearboxes 506;

[0061] It should be noted that, as described above, the operation of the negative pressure drive 505 drives the negative pressure gearbox 506 on its drive end, which in turn drives the inner negative pressure threaded tube 509 to rotate. This, in turn, causes the inner negative pressure threaded rod 507 to rotate, resulting in stable lifting and lowering of the threaded rod 507 along the inner side of the negative pressure threaded tube 509. Simultaneously, the threaded rod 507 drives the negative pressure stretching plate 508, causing it to stably lift and lower along the inner side of the negative pressure chamber 504. Furthermore, the negative pressure inside the reaction chamber... Air inside the toothed drainage pipe 503 is drawn into the negative pressure box 504. Similarly, air inside several L-shaped drainage and stirring pipes 501 is drawn into the toothed drainage pipe 503. Then, the negative pressure drive 505 runs in reverse, thereby drawing the liquid inside the negative pressure box 504 into the inside of several L-shaped drainage and stirring pipes 501. Through the cooperation of several threaded inner blades 502, the rotating liquid flow inside the L-shaped drainage and stirring pipes 501 is drawn into the inside of the degreasing concave box 1, galvanizing box 3, quenching and drying box 4, electroplating and anti-corrosion box 6, and cleaning and drying box 7, thereby achieving mixing and stirring.

[0062] As a preferred embodiment, the degreasing concave box 1, the galvanizing box 3, and the electroplating anti-corrosion box 6 are each equipped with a raw material box, and each of the raw material boxes is equipped with a feeding valve.

[0063] As a preferred option, furthermore, each of the three feeding valves is equipped with a flow sensor.

[0064] As a preferred option, furthermore, each of the auxiliary kit brackets 8 is equipped with a tension sensor.

[0065] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
