It includes a flipping mechanism and a rangefinder. When replenishing the molten zinc in the zinc pot, the zinc ingot is hooked by the translation zinc-adding component, and the flipping support is flipped up. With the movement of the translation zinc-adding component, the zinc ingot comes into contact with the high-temperature molten zinc in the zinc pot, thus achieving replenishment. The rangefinder obtains the molten zinc level data in real time, and the movement of the translation drive I is controlled by a host computer, enabling automated and precise level control of the molten zinc in the zinc pot, thereby improving the quality of strip galvanizing.

Description

Technical Field

[0001] This invention relates to the field of continuous galvanizing technology, and in particular to automated production line equipment for continuous galvanizing. Background Technology

[0002] Zinc is a metal with moderate ductility. At room temperature, a thin, dense film of basic zinc carbonate forms on the surface of zinc, preventing further oxidation and protecting the zinc interior from corrosion, thus extending the material's service life. Due to this property, zinc is often used in industry to coat steel plates to prevent corrosion; such galvanized steel plates are called galvanized sheets. Steel strip refers to a conveyor belt made of carbon steel, used as a traction and transport component in belt conveyors, and also for bundling goods. It is a narrow, long steel plate produced by various steel rolling mills to meet the needs of different industrial sectors for the industrialized production of various metal or mechanical products. There are two methods for galvanizing steel strip: electro-galvanizing and hot-dip galvanizing. Electro-galvanizing produces a thinner coating and involves a more complex process. Hot-dip galvanizing, on the other hand, is simpler, produces a thicker coating, and is easier for modern large-scale production. Hot-dip galvanizing is further divided into single-sheet galvanizing and continuous galvanizing. Single-sheet hot-dip galvanizing using the flux method involves stacking hot-rolled thin sheets, which are annealed and then sent to the galvanizing workshop. The surface oxide scale is removed by pickling, and after being coated with solvent and dried, the sheets are placed in a zinc bath for hot-dip galvanizing. This method is obsolete due to its low output, high cost, poor quality, severe environmental pollution, and low economic efficiency. It has been replaced by modern, large-scale, continuous hot-dip galvanizing production lines that offer high quality, high output, low consumption, and significant economic benefits. These lines have low production costs, are easy to implement, and provide anodic protection: when the coating is intact, it acts as an insulating layer; if minor damage occurs, the coating itself corrodes due to electrochemical action, thus protecting the steel from corrosion. Hot-dip galvanized steel strips have a thick, strong coating, a beautiful and glossy appearance, and are therefore highly favored and increasingly widely used.

[0003] The zinc-adding operation of a continuous hot-dip galvanizing unit involves factors such as zinc pot temperature, zinc pot level, zinc dross formation, and zinc ingot loss, all of which have a significant direct or indirect impact on product quality. Zinc ingots must be added promptly to a continuous hot-dip galvanizing unit; zinc should be added as soon as the zinc pot level drops, rather than waiting until the level has dropped significantly before adding several ingots. This is to minimize fluctuations in the zinc pot level and temperature.

[0004] In current continuous galvanizing production lines, after the zinc material in the zinc pot is consumed, zinc blocks for replenishment are usually placed into the zinc pot manually or using hoisting equipment. For ease of raw material management, the zinc blocks are typically the industry standard zinc ingot 1, which weighs 1 ton per block and is relatively large. Zinc ingot 1 is brick-shaped, with a through hole 11 on each side. This through hole 11 facilitates demolding or hoisting of the zinc ingot 1. Its structure is as follows: Figure 1 and Figure 2As shown. The inventors believe that manually placing zinc ingot 1 directly into the zinc pot is time-consuming and labor-intensive, and can only be done in whole pieces, making it impossible to accurately control the zinc liquid level in the zinc pot; using hoisting equipment to lift zinc ingot 1 for zinc addition requires the zinc ingot 1 to be hoisted above the zinc pot surface, and then the operator manually operates the hoisting equipment to add the zinc ingot 1 to the zinc pot according to the zinc pot level, which is obviously not only dangerous, but also lacks precision in controlling the zinc addition speed; the suspended zinc ingot will not only swing, easily causing fluctuations in the zinc pot level, but also occupy the limited strip steel conveying operation space above the zinc pot, causing friction and interference with the strip steel. Summary of the Invention

[0005] In order to overcome the shortcomings of existing technologies, such as the inability to achieve precise quantitative automated dispensing of zinc blocks, and thus the inability to control the level of zinc liquid in the zinc pot.

By setting up a tilting mechanism, the operation of lifting zinc ingots above the zinc pot surface using hoisting equipment is avoided, thus achieving automated zinc addition. Combined with a liquid level measuring system, precise liquid level control of the zinc in the zinc pot is achieved, thereby improving the quality of galvanized strip steel.

The electrical control system is communicatively connected to a host computer. The rear end of the translation zinc-adding assembly is connected to a zinc-adding part via a double-crank structure. The zinc-adding part includes a hook. A lifting piston cylinder is installed between the zinc-adding part and the translation zinc-adding assembly.

[0016] In some embodiments of this disclosure, the assembly frame includes a base frame, the base frame is provided with a slide rail, the slide rail is parallel to the receiving slide, the slide rail is provided with a bearing slide plate, the hinged vertical shaft is provided on one side of the bearing slide plate, the other side of the bearing slide plate is provided with a connecting block, the swing arm piston cylinder acts between the connecting block and the lever; a limit switch is provided on each of the left and right paths of the lever's swing stroke.

[0017] Compared with existing technologies, the above-mentioned automated precision quantitative zinc-adding machine has the following advantages:

[0018] When it is necessary to replenish the zinc pot with zinc liquid, simply hook the zinc ingot with the translation zinc feeding component, flip up the flipping bracket, and move the translation zinc feeding component to make the zinc ingot contact the high-temperature zinc liquid in the zinc pot to achieve replenishment. With the help of the rangefinder, the zinc liquid level data can be obtained in time, and the movement of the translation drive I can be controlled by the host computer to achieve precise liquid level control of the zinc liquid in the zinc pot.

[0019] By setting up the zinc addition component, large-weight and large-volume zinc ingots can be added into the zinc pot from one side, which can effectively avoid drastic fluctuations in the level and temperature of the zinc liquid in the zinc pot and improve the quality of strip galvanizing.

[0020] By setting up a flipping mechanism, the operation of lifting equipment to lift zinc ingots above the zinc pot liquid surface is avoided, and contact interference between the lifting equipment and the automated conveying path of the strip steel and / or the zinc pot nose is avoided. The production space is optimized and the equipment has a high degree of integration; the safety production risks of suspending large-volume and heavy zinc ingots are avoided.

The process is fast and efficient. There is no need to flip the heavy and bulky zinc ingot during connection. It is very convenient to hook the zinc ingot and quickly enter the zinc-adding state, resulting in a short process cycle. Attached Figure Description

[0039] To better understand the purpose, structure, and function of this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below. It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit this application.

[0040] As shown in the attached diagram. Figures 3 to 15As shown, an automated, precise, quantitative zinc-adding machine is designed, including a flipping mechanism 2 and a rangefinder. The terms "including" and "equipped with," and any variations thereof, in this application are open-ended and intended to cover non-exclusive inclusion. The flipping mechanism 2 includes a frame 21, with a hinge 211 on its upper part. A flipping arm 22 is hinged to the hinge 211. The flipping arm 22 has a receiving slide 221. A flipping arm piston cylinder 23 is disposed between the front of the flipping arm 22 and the front of the frame 21. The boundary between the front and rear parts can be the location of the hinge 211. In the description of this application, it should be understood that the directional terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate directional or positional relationships based on the appended... Figure 5 The orientations or positional relationships shown are for descriptive purposes only and do not indicate or imply that the device or unit referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this application. The tilting arm piston cylinder 23 is equipped with a hydraulic control system; the receiving slide 221 is equipped with a translation zinc-adding assembly 24, which includes a translation drive I 241. In this document, the serial number of the component is used only to distinguish the objects described and has no sequential or technical meaning. The translation drive I 241 is equipped with an electronic control system, which is connected to a host computer or microcontroller that can directly send operation commands. The host computer controls the translation drive I 241 and the rangefinder to achieve automated zinc adding and automated control of the zinc liquid level in the zinc pot, saving a lot of manpower and reducing the safety hazards caused by operators working in close contact with the zinc pot, which is in line with the enterprise's goal of reducing labor costs. The production requirements depend on the following: The rear end of the translation zinc-adding assembly 24 is connected to the zinc-adding part 25 via a double-crank structure. The zinc-adding part 25 includes a hook 251. A lifting piston cylinder 26 is provided between the zinc-adding part 25 and the translation zinc-adding assembly 24. The lifting piston cylinder 26 is controlled by the hydraulic control system. Through the double-crank structure of the translation zinc-adding assembly 24, the hook 251 can be raised vertically under the action of the lifting piston cylinder 26 to directly connect to the through hole 11 of the zinc ingot 1. The process is fast and efficient. When connecting, there is no need to flip the heavy and large-volume zinc ingot 1. It is very convenient to hook the zinc ingot 1 and quickly enter the state to be zinc-adding. The process cycle is short. The rangefinder is controlled by the electrical control system. Through the setting of the translation zinc-adding assembly 24, heavy and large-volume zinc ingots 1 can be added into the zinc pot 7 from one side. This can effectively avoid drastic fluctuations in the level and temperature of the zinc liquid in the zinc pot 7 and improve the quality of strip galvanizing.

[0041] When zinc pot 7 needs to be replenished, zinc ingot 1 is placed in the receiving slide 221. The electronic control system controls the translation zinc-adding assembly 24 to move below the zinc ingot 1. The lifting piston cylinder 26 is operated to engage the hook 251 with the through hole 11 at the front end of the zinc ingot 1. The electronic control system then controls the translation zinc-adding assembly 24 to move to the rear end of the tilting mechanism 2. The tilting arm piston cylinder 23 is activated, causing the front end of the tilting arm 22 to rise and the rear end to fall. The liquid level data of the zinc liquid in zinc pot 7 is measured by the rangefinder and transmitted to the upper... The host computer controls the tilting angle of the tilting arm 22 or the position of the translational zinc-adding component 24 to achieve the contact volume between the zinc ingot 1 and the hot zinc liquid in the zinc pot, thereby realizing automated and precise liquid level control of the zinc liquid in the zinc pot. During this process, the rangefinder keeps detecting the liquid level of the zinc liquid in the zinc pot 7 in real time. As the zinc ingot 1 melts in the zinc pot 7, when the liquid level in the zinc pot 7 rises to the specified height, the translational zinc-adding component 24 stops descending. After the rangefinder measures that the strip plate has consumed a certain amount of zinc liquid, the translational zinc-adding component 24 descends again. This function is repeated in sequence. After the hook trolley reaches the end of its stroke, a small portion of the zinc block has not completely fallen into the zinc liquid. At this time, the lifting piston cylinder 26 controls the double crank structure to partially descend the hook 251, so that the zinc block completely falls into the zinc liquid, and the zinc material on the hook 251 is completely melted. Subsequently, the hook 251 is raised, and the translation zinc loading assembly 24 returns to the waiting position for receiving materials. The above steps are repeated to start the next operation cycle. By setting up the flipping mechanism 2, the operation of lifting equipment to lift zinc ingot 1 above the liquid surface of zinc pot 7 is avoided, and the contact interference between the lifting equipment and the automated conveying path of strip steel and / or zinc pot nose 6 is avoided. The production space is optimized and the equipment has a high degree of integration. The safety production risks of suspending large-volume and heavy zinc ingot 1 are avoided.

[0042] The above embodiments illustrate three examples of implementing the aforementioned technical solutions. The term "embodiment" as used herein means that a specific feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of this application. The appearance of this phrase in various locations within the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. Where there is no conflict, the various embodiments in this application can be combined with each other.

[0043] Embodiment 1 discloses an automated, precise, quantitative zinc-adding machine, including a turning mechanism 2 and a rangefinder. The detection direction of the rangefinder is perpendicular to the surface of the molten zinc in the zinc pot 7. The turning mechanism 2 includes a frame 21, which can be a welded sheet metal frame. The upper part of the frame 21 is provided with a hinge 211, and a turning arm 22 is hinged to the hinge 211. The turning arm 22 is provided with a receiving slide 221. A turning arm piston cylinder 23 is disposed between the front part of the turning arm 22 and the front part of the frame 21. The turning arm piston cylinder 23 is a hydraulic cylinder, which has high force and smooth operation. This effectively improves the safety factor. The dividing point between the front and rear parts can be the location of the hinge 211. The tilting arm piston cylinder 23 is equipped with a hydraulic control system. The receiving slide 221 is equipped with a translation zinc-adding assembly 24. The translation zinc-adding assembly 24 includes a translation drive I 241, which includes a motor and a reducer. The translation drive I 241 is equipped with an electronic control system, which is communicatively connected to a host computer. In this embodiment, the host computer can be a microcontroller. Automated zinc-adding is achieved through the cooperation of the translation drive I 241 and the rangefinder. The automated control of the zinc pot's molten zinc level saves significant manpower and reduces safety hazards associated with close contact with the zinc pot, meeting the company's need to reduce reliance on manual labor. The rear end of the translational zinc-adding assembly 24 is connected to a zinc-adding section 25 via a double-crank structure. The zinc-adding section 25 includes a hook 251, and a lifting piston cylinder 26 is provided between the zinc-adding section 25 and the translational zinc-adding assembly 24. The lifting piston cylinder 26 controls the hook 251 to rise or fall. The lifting piston cylinder 26 is controlled by the hydraulic control system, and the translational zinc-adding assembly 24... The double-crank structure of the 4 allows the hook 251 to be raised vertically under the action of the lifting piston cylinder 26, directly connecting to the through hole 11 of the zinc ingot 1. The process is quick and efficient, and there is no need to flip the heavy and large zinc ingot 1 during connection. It is very convenient to hook the zinc ingot 1 and quickly enter the zinc-adding state, resulting in a short process cycle. The rangefinder is controlled by the electronic control system. By setting the zinc-adding component 24, heavy and large zinc ingots 1 can be added to the zinc pot 7 from one side, which can effectively avoid drastic fluctuations in the zinc liquid level and temperature in the zinc pot 7 and improve the quality of strip galvanizing.

[0044] A stop switch is provided between the front of the tilting arm 22 and the front of the frame 21 to ensure that the receiving slide 221 is in a horizontal position when the tilting arm piston cylinder 23 retracts and resets, preventing the zinc ingot 1 from sliding on the receiving slide 221. The translation zinc loading assembly 24 is a hook trolley. The tilting arm 22 is equipped with a rack I 222, which is parallel to the receiving slide 221. The translation drive I 241 is equipped with a drive gear I, which works with the rack I 222. The control system can realize timely stopping or reversing of the translation zinc loading assembly 24 with high control precision. It has good load-bearing capacity and is suitable for heavy and large-volume zinc ingots 1; the rangefinder is a laser rangefinder, suitable for high-temperature working environments near zinc pots; the hook 251 is provided on the upper surface of the zinc-adding part 25, and the hook 251 is a straight hook post used for the through hole of the zinc ingot, so that the hook 251 can directly connect to the through hole 11 of the zinc ingot 1. The process is fast and efficient. When connecting, there is no need to turn the heavy and large-volume zinc ingot 1. It is very convenient to hook the zinc ingot 1 and quickly enter the state to be added with zinc. The process cycle is short. In this embodiment, the hook 251 and the through hole 11 are clearance fit; in this embodiment, the feeding slide 311 and the receiving slide 221 are both slides composed of rolling rollers.

[0045] Example 2 discloses an automated, precise, quantitative, flipping zinc-adding machine. The difference between this example and Example 1 is that in this example, the host computer can be a computer; the zinc-adding section 25 has a box-frame structure, welded from high-temperature resistant metal parts. This box-frame structure reduces weight, lessening the working pressure on the translation drive I 241, and also reducing the meshing load pressure between the drive gear I and the rack I 222 during zinc addition; the upper end of the hook 251 has a chamfer and / or rounded corner for quick and easy connection with the through hole 11; above the receiving slide 221... An anti-detachment guard 27 is provided. The anti-detachment guard 27 is a metal frame that is connected to both sides of the receiving slide 221. It prevents the zinc ingot 1 from falling off the receiving slide 221 due to the shift of the center of gravity and shaking after the tilting arm 22 is tilted up, thus effectively reducing the safety risk. In this embodiment, both the feeding slide 311 and the receiving slide 221 are channels. When in use, the zinc ingot 1 is placed in the slot of the channel, which can effectively prevent the zinc ingot 1 from swaying and deviating from the path during movement, thus avoiding excessive load on the translation drive I 241 and / or translation drive II 321.

[0046] like Figures 3 to 15As shown, Embodiment 3 discloses an automated, precise, quantitative zinc-adding machine. The difference between this embodiment and Embodiment 2 is that it further includes a feeding mechanism 3. The feeding mechanism 3 includes a transmission support 31, which is provided with a horizontally positioned feeding slide 311. The feeding slide 311 is equipped with a translational pushing component 32, which includes a translational drive II 321. The translational drive II 321 includes a motor and a reducer. When the tilting arm 22 is in a non-tilting state, the rear end of the feeding slide 311 is connected to the front end of the receiving slide 221. In use, zinc ingots 1 are transported or hoisted onto the feeding slide 311, and the zinc blocks are pushed in by the translational pushing component 32. The position to be hooked for the translation zinc-adding assembly 24; a travel stop switch is provided between the front part of the tilting arm 22 and the front part of the frame 21 to further ensure the angle of docking between the rear end of the feeding slide 311 and the front end of the receiving slide 221; in this embodiment, both the feeding slide 311 and the receiving slide 221 are smooth planes, and each side is provided with a limiting member, which can be a partition or a rolling bearing to reduce friction; the translation pushing assembly 32 is a pushing trolley, the feeding mechanism 3 is provided with a rack II, the rack II is parallel to the feeding slide 311, the translation drive II 321 is provided with a drive gear II, the drive gear II is used in conjunction with the rack II, and the pushing trolley... The rear end acts on the zinc ingot 1, and the movement of the pusher trolley is controlled by the translation drive II 321; the rear end of the frame 21 is connected to the zinc pot slag remover 4.

A lever 42 is hinged to the hinged vertical shaft 411. A swing arm piston cylinder 43 is fitted between the inner end of the lever 42 and the assembly frame 41. A slag-removing plate 421 is provided at the outer end of the lever 42, allowing direct contact between the slag-removing plate 421 and the zinc liquid. The slag-removing plate 421 is made of high-temperature resistant metal. In this embodiment, a thin steel sheet can be used. The swing arm piston cylinder 43 can be a hydraulic cylinder connected to the hydraulic control system or a pneumatic cylinder equipped with a pneumatic system. In this embodiment, a pneumatic cylinder is used to ensure that the slag-removing plate 421 reacts quickly. In this embodiment, the assembly frame 41 includes a base frame 412. The base frame 412 is provided with a slide rail 413. The slide rail 413 is parallel to the receiving slide 221. The slide rail 413 is equipped with a bearing slide plate 414. The bearing slide plate 414 is equipped with a limiting part for locking the relative position between the slide rail 413 and the bearing slide plate 414, thereby controlling the length of the lever 42 extending into the zinc pot 7.The hinged vertical shaft 411 is located on one side of the bearing slide plate 414, and a connecting block 415 is located on the other side of the bearing slide plate 414. The swing arm piston cylinder 43 acts between the connecting block 415 and the lever 42. A limit switch 44 is provided on each of the left and right paths of the lever 42's swing stroke. The limit switches 44 control the stroke of the swing arm piston cylinder 43, avoiding wasted preparation time for the ranging sensor caused by excessive stroke of the lever 42, effectively improving the continuity of zinc liquid level measurement. A short swing path also maintains the cleanliness of the swing path, ensuring real-time measurement by the laser ranging sensor.
