Description

Technical Field

[0001] The present disclosure relates to the technical field of hot-dip galvanizing, and particularly to an experimental device for analyzing the overflow state and slag discharge condition of a galvanizing furnace nose. Background Art

[0002] Galvanizing the surface of strip steel is currently the most cost-effective, easy and aesthetic anti-corrosion method with wide applications. Among them, hot-dip galvanizing has advantages such as uniform coating, strong adhesion and long service life, and is mainly carried out in a zinc pot. After the strip steel is cleaned and pretreated, it enters the high-temperature molten zinc liquid from the furnace nose, and is guided by the zinc pot rollers to leave the zinc liquid, and finally the excess zinc liquid is blown off by an air knife to obtain a uniform coating.

[0003] However, the zinc ash and zinc slag generated in the hot-dip galvanizing process may adhere to the surface of the strip steel with the shaking of the strip steel and the flow of the zinc liquid, forming surface quality defects. With the increasing maturity of the hot-dip galvanizing technology, the surface quality of galvanized strip steel has been improving year by year, but this defect still cannot be eliminated and can only be controlled. Since the strip steel first contacts the zinc liquid in the furnace nose, which is the key position where zinc ash and zinc slag defects occur, an inner trough plate structure is generally set at the bottom of the furnace nose to form an overflow, and a zinc ash and zinc slag extraction pump is externally set to extract the zinc ash and zinc slag that appear in this process, thereby reducing the incidence of surface defects. However, due to the different inner trough plate structures of the furnace nose, the overflow state of the furnace nose is also different, which may cause the zinc ash and zinc slag to not be discharged in time, increasing the incidence of this defect. And the high-temperature non-transparent state of the zinc liquid makes it difficult to observe this defect, so that the occurrence of defects is unpredictable and uncontrollable.

[0004] Therefore, it is necessary to propose an experimental device for analyzing the overflow state and slag discharge condition of a galvanizing furnace nose to at least partially solve the problems existing in the prior art. Summary of the Invention

[0050] It can be understood that the experimental device 100 for analyzing the overflow state and slag discharge situation of a galvanizing furnace nose is provided with a liquid storage part 110, a conveying part 120, a furnace nose model 130, a pumping and sending pump 140, and an adjusting part. Among them, the liquid storage part 110 can store a transparent liquid. The zinc pot is simulated by the liquid storage part 110, the zinc liquid is simulated by the transparent liquid, and non-transparent plastic particles are placed in the transparent liquid to simulate zinc ash and zinc slag. The density of the non-transparent plastic particles is less than that of the transparent liquid, so that the non-transparent plastic particles float on the liquid surface of the transparent liquid to restore as much as possible the floating situation of zinc ash and zinc slag in the zinc liquid. The conveying belt 150 is conveyed through the conveying part 120. The belt 150 contacts the transparent liquid after passing through the furnace nose model 130. The strip steel is simulated by the belt 150, so as to simulate the galvanizing process of the belt 150. By observing the amount of zinc ash and zinc slag on the belt 150, the current simulated galvanizing quality can be simulated. The pumping and sending pump 140 enters the interior of the furnace nose model 130 through the slag discharge port 133 of the furnace nose model 130, and a part of the non-transparent plastic particles overflowing between the plate body and the inner frame 132 of the furnace nose model 130 is pumped out by the pumping and sending pump 140 to simulate the extraction of a part of zinc ash and zinc slag between the plate body and the inner frame 132 of the furnace nose by the pumping and sending pump 140 in reality. With such a setting, by setting the transparent liquid, the flow field of the non-transparent plastic particles in the transparent liquid can be observed in real time to truly simulate the flow field of zinc ash and zinc slag. The state of the furnace nose model 130 is adjusted by the adjusting part. The state of the furnace nose model 130 includes the swing angle and the insertion depth of the furnace nose. With such a setting, by adjusting the state of the furnace nose model 130 and the structural parameters of the furnace nose model 130, the overflow state of the transparent liquid in the furnace nose model 130 can be adjusted, so as to determine the corresponding slag discharge situation of the furnace nose model 130, and further determine the optimization trend and law of the state and structure of the furnace nose model 130, so as to optimize the slag discharge effect, reduce the occurrence rate of surface defects in the hot-dip galvanizing process, and improve the product quality.

[0051] It can be understood that the experimental parameters include the conveying speed parameter of the strip steel, the flow rate parameter of the pumping and sending pump 140, the width of the strip steel, etc. The experimental device 100 for analyzing the overflow state and slag discharge situation of a galvanizing furnace nose can also be provided with a control module. The control module can be used to adjust the experimental parameters. For example, the control module can control the conveying speed of the strip steel and control the flow rate of the pumping and sending pump 140. By increasing the experimental parameter variables, the influence of the above experimental parameters on the slag discharge situation can be determined to further improve the optimization trend and law of the state and structure of the furnace nose model 130.

[0052] In some examples, such as Figure 1 and Figure 2As shown, the furnace nose model 130 includes: a housing 131. Along the conveying direction of the belt 150, a first conveying port is provided on the top plate of the housing 131, and a second conveying port is provided on the bottom plate of the housing 131; four plate bodies are arranged on the bottom plate and surround the second conveying port. The four plate bodies form an inner frame 132. The inner frame 132, the first conveying port and the second conveying port are interconnected along the conveying direction of the belt 150; there are two slag discharge ports 133, which are respectively arranged on both sides in the width direction of the housing 131 and close to the bottom plate. Among them, the pumping pump 140 is connected to the slag discharge port 133 on the side close to the liquid storage part 110.

[0053] It can be understood that the furnace nose model 130 can be provided with a housing 131 and an inner frame 132. Among them, a first conveying port is provided on the top plate of the housing 131, and a second conveying port is provided on the bottom plate of the housing 131, and the first conveying port and the second conveying port are connected and communicated along the conveying direction of the belt 150. The inner frame 132 is formed by surrounding four plate bodies. The inner frame 132 is located on the bottom plate and on the periphery of the second conveying port to support the inner frame 132 through the bottom plate. The inner frame 132, the first conveying port and the second conveying port are interconnected along the conveying direction of the belt 150. There are two slag discharge ports 133, which are respectively arranged on both sides in the width direction of the housing 131 and close to the bottom plate direction. After part of the furnace nose model 130 is placed in the liquid storage part 110, the transparent liquid will overflow between the housing 131 and the inner frame 132 of the furnace nose model 130. The pumping pump 140 can pump out the transparent liquid that overflows between the housing 131 and the inner frame 132 of the furnace nose model 130, and then pump out the non-transparent plastic particles in the overflowing transparent liquid, so as to reduce the influence of the non-transparent plastic particles on the belt 150.

[0054] In some examples, both the housing 131 and the plate bodies are made of transparent materials.

[0055] It can be understood that both the housing 131 and the plate bodies are made of transparent materials, so as to facilitate the operator to observe the internal situation of the housing 131, as well as the flow field of the non-transparent plastic particles in the transparent liquid that overflows between the housing 131 and the inner frame 132 of the furnace nose model 130. And the situation of the belt 150 passing through the furnace nose model 130 can be observed, as well as whether there are non-transparent plastic particles sticking to the belt 150. Thus, while truly simulating the actual situation of the strip steel passing through the furnace nose, the experimental situation can be observed in real time, which is convenient for adjusting the experimental parameters, the state of the furnace nose model 130 and the structural parameters of the furnace nose model 130 according to the experimental situation, and then determining the optimization trend and law of the state and structure of the furnace nose model 130, so as to optimize the slag discharge effect, reduce the incidence of surface defects in the hot-dip galvanizing process, and improve the product quality.

[0056] In some examples, the adjusting part includes: a connecting beam, holes are formed at corresponding positions on opposite sides of the liquid storage part 110, and the connecting beam passes through the two holes; a connecting piece, the housing 131 is connected to the connecting beam through the connecting piece; wherein, the area of the hole is larger than the cross-sectional area of the connecting beam.

[0057] It can be understood that the adjusting part is provided with a connecting beam and a connecting piece. Among them, holes are formed at corresponding positions on opposite sides of the liquid storage part 110, and the connecting beam passes through the two holes so that the connecting beam penetrates through the liquid storage part 110. The housing 131 is connected to the connecting beam through the connecting piece, and the area of the hole is larger than the cross-sectional area of the connecting beam, so that the connecting beam can rotate in the hole and the position of the connecting beam in the hole can be adjusted. With such a setting, by adjusting the rotation angle of the connecting beam and the position of the connecting beam in the hole, the position and angle of the furnace nose model 130 relative to the liquid storage part 110 are adjusted. Thereby, the installation horizontal position, vertical position and swing angle of the furnace nose model 130 in the structural parameters of the furnace nose model 130 are adjusted to determine the state of the furnace nose model 130 and the optimization trend and law of the structure, so as to optimize the slag discharge effect, reduce the occurrence rate of surface defects in the hot-dip galvanizing process, and improve the product quality.

[0058] Exemplarily, the hole can be one of a rectangular hole, a waist-shaped hole or a circular hole, and the connecting piece can be a fastening bolt.

[0059] In some examples, the adjusting part further includes: a positioning plate, which is arranged in the hole and is used for positioning the connecting beam after adjusting the position of the connecting beam in the hole; a fixing piece, after the positioning part positions the connecting beam, the position of the connecting beam is fixed through the fixing piece.

[0060] It can be understood that the adjusting part can also be provided with a positioning plate and a fixing piece. Among them, the positioning plate can be clamped in the hole to position the connecting beam after the position of the connecting beam is adjusted, and then the position of the connecting beam is fixed through the fixing piece to ensure the position stability of the connecting beam. Specifically, a plurality of slots arranged at intervals can be formed on the inner side wall of the hole according to the cross-sectional size of the connecting beam. After adjusting the position of the connecting beam in the hole, the positioning plate is inserted into the slot closest to the connecting beam to limit the position of the positioning plate. The fixing piece can be a fastening bolt, a plurality of threaded holes can be formed on the circumferential side of the connecting beam, and a plurality of long holes are arranged at intervals on the positioning plate. When fixing the position of the connecting beam, a gasket is laid at the long hole to limit the axial displacement of the fastening bolt, and the fastening bolt is operated to pass through the long hole and be screwed into the threaded hole to fix the position of the connecting beam.

[0061] In some examples, it further includes: an angle detection piece, which is used for detecting the swing angle of the housing 131 relative to the liquid storage part 110; a position detection piece, which is used for detecting the position of the housing 131 relative to the liquid storage part 110.

Among them, the swinging angle of the housing 131 relative to the liquid storage part 110 is detected by the angle detection component; the position of the housing 131 relative to the liquid storage part 110 is detected by the position detection component. To accurately detect the installation horizontal position, vertical position and swinging angle of the furnace nose model 130, which is convenient for real-time tracking and detecting and recording the structural parameters of the furnace nose model 130, and then determining the state of the furnace nose model 130 and the optimization trend and law of the structure, so as to optimize the slag discharge effect, reduce the incidence of surface defects in the hot-dip galvanizing process, and improve the product quality.

[0063] In some examples, it further includes: a camera device for photographing a part of the belt 150 that enters the liquid storage part 110 through the furnace nose model 130 to determine the amount of non-transparent plastic particles on the belt 150; a storage module for storing the swinging angle data detected by the angle detection component, the position data detected by the position detection component, and the non-transparent plastic particle amount data; an analysis module for analyzing the relationship between the overflow state and the slag discharge situation according to the swinging angle data, the position data, and the non-transparent plastic particle amount data, so as to determine the structural optimization trend and law of the furnace nose model 130.

[0064] It can be understood that the experimental device 100 for analyzing the overflow state and slag discharge situation of the galvanizing furnace nose is also provided with a camera device, a storage module and an analysis module. Among them, a high-speed camera can be selected as the camera device to clearly capture the amount of non-transparent plastic particles on the belt 150 passing through the liquid storage part 110. The storage module can store the corresponding swinging angle data detected by the angle detection component, the position data detected by the position detection component, and the non-transparent plastic particle amount data. The analysis module analyzes the relationship between the overflow state and the slag discharge situation according to the swinging angle data, the position data, and the non-transparent plastic particle amount data, so as to determine the structural optimization trend and law of the furnace nose model 130, so as to optimize the slag discharge effect, reduce the incidence of surface defects in the hot-dip galvanizing process, and improve the product quality.

[0065] Exemplarily, the storage module can also store multiple experimental parameters.

Among them, the first roller 121 serves as the driving roller, and the belt 150 is tightened and conveyed by the first roller 121, the second roller 122, and the third roller 123.

[0067] It can be understood that the conveying unit 120 is also provided with a driving member 124, a first roller 121, a second roller 122, and a third roller 123.

The belt 150 is tightened by the first roller 121, the second roller 122, and the third roller 123. With such a setting, the conveying stability can be improved. The driving member 124 drives the first roller 121 to rotate, so as to convey the belt 150 through the furnace nose model 130 and then into the transparent liquid in the liquid storage unit 110, and then the belt 150 exits the transparent liquid.

[0068] In some examples, the belt 150 is a seamless belt 150.

[0069] It can be understood that the belt 150 can be selected as a seamless belt 150 to simulate the strip steel as much as possible, avoid non-transparent plastic particles from entering the seams, and improve the accuracy of experimental simulation.
