Description

Technical Field

[0001] The utility model relates to the technical field of galvanized metal surface treatment technology, in particular to a non-contact treatment device for gathering zinc liquid floating matter used in the galvanizing process. Background Art

[0002] During the galvanizing process, a zinc pot is used to melt zinc ingots and maintain their liquid state to meet the production needs of hot-dip products. During this process, the liquid metal's surface comes into contact with air, causing condensation and oxidation, resulting in surface scrap metal. If not promptly treated, large areas of crystallization and oxide scum can form on the liquid surface, significantly impacting product quality and causing degradation. In severe cases, this can damage production equipment, necessitating prompt cleaning. Currently, surface scrap metal removal is primarily performed manually. Operators, wearing protective gear, use a specially designed long-handled scoop (approximately 2 meters long) around the zinc pot, gently touching the surface to collect the surface scrap metal. This scrap metal is then removed and placed in a slag bin. The center area of ​​the zinc pot is the hot-dip coating area. Care must be taken during slag collection to avoid collision with the high-speed product. During cleaning, gentle movements are required to avoid disturbing the liquid surface, which can affect product quality. The ambient temperature around the zinc pot is high (approximately 450°C), posing safety risks due to volatilization and high-temperature liquids. The operation time is long, generally no less than 30 minutes per slag removal process, and frequent cleaning operations are required. Therefore, there is an urgent need for a zinc liquid floating object aggregation and treatment device for the galvanizing process to collect scrap metal on the surface of the zinc liquid during the galvanizing process, thereby reducing the workload of manual operation and avoiding the safety risks of manual operation.

A first suspension bracket 3 is fixedly installed on one side of the top of the concrete base 2, and a second suspension bracket 4 is fixedly installed on the other side of the top of the concrete base 2. A third suspension bracket 5 is welded between the first suspension bracket 3 and the second suspension bracket 4, and a first adjustment rod 6 is provided on the top of the first suspension bracket 3, the second suspension bracket 4 and the third suspension bracket 5, and a main magnetic coil 9 is fixed to the bottom of the first adjustment rod 6 through a main magnetic hanging ring 8. The inner wall around the main magnetic coil 9 rotates A second adjustment rod 7 is installed with equal distances, and an auxiliary magnetic coil 10 is rotatably installed on the outer wall of the second adjustment rod 7. The main magnetic coil 9 and the auxiliary magnetic coil 10 are connected to the electric control box 11 through a wire, and the electric control box 11 is connected to the cooling control box 12 through a signal line. A furnace nose magnetic coil 21 is provided on one side of the main magnetic coil 9, and the furnace nose magnetic coil 21 is connected to the furnace nose 20. The main magnetic coil 9, the auxiliary magnetic coil 10 and the furnace nose magnetic coil 21 are all supported by the outer shell 15, and the top outer wall of the outer shell 15 is provided with a lifting ring 22;

[0026] By utilizing the main magnetic coil 9 and the furnace nose magnetic coil 21 to generate plane traveling wave magnetic fields in clockwise and counterclockwise directions, and the auxiliary magnetic coil 10 to generate a plane traveling wave magnetic field from the inside to the outside, the plane traveling wave magnetic field exerts a force on the liquid metal, and driven by the force, the liquid metal flows in a predetermined direction, so that the surface scrap metal gathers in the convergence area 23, forming a closed magnetic area in the convergence area 23, reducing the dispersion of the surface scrap metal in the convergence area 23, thereby improving the surface purity of the zinc liquid and improving the galvanizing effect.

[0027] A metal plate 19 is vertically inserted into the inner wall of the zinc pot 1, and the metal plate 19 and the furnace nose 20 are arranged parallel to each other. A silicon steel rod 16 is arranged inside the shell 15, and a plurality of equidistantly distributed zigzag silicon steel sheets 18 are superimposed on the outer wall of the silicon steel rod 16, and copper coils 17 are wound between the zigzag silicon steel sheets 18;

[0028] The top of the copper coil 17 is connected to a busbar support 13, and the busbar support 13 is provided with a power bus 14. The width ratio of the serrated silicon steel sheet 18 to the width of the copper coil 17 is 10:13, and the number of silicon steel rod slots is an integer multiple of 3 and not less than 6.

[0029] A collecting area 23 is provided at one corner of the top of the zinc pot 1, and the ratio of the side length of the collecting area 23 to the width of the silicon steel rod 16 is 0.8;

[0030] When this embodiment is used, first, according to the size of the zinc pot 1 and the original size data, x is the distance between the auxiliary magnetic coils 10. The auxiliary coil on the furnace nose 20 side is installed perpendicular to the main coil, and the two auxiliary coils in the middle of the strip side are installed perpendicular to the main coil. The remaining auxiliary magnetic coils are installed pointing to the DS point and the OS point respectively, and form an angle α with the main magnetic coil. The DS point and the OS point are the two widest sides of the strip. a and c are the coverage distances of the auxiliary coils, and b and d are the distances from the edge of the strip to the installation position of the auxiliary magnetic coils. The corresponding relationship is a=0.6*b, c=0.5*d. After adjusting the positional relationship between the auxiliary magnetic coil 10 and the main magnetic coil 9 to a suitable height, the height position of the main magnetic coil 9 is adjusted by rotating the first adjusting rod 6. According to the depth of the zinc liquid inside the zinc pot 1, the main magnetic coil 9 is adjusted to a distance from the zinc liquid. The liquid level height is 100mm, and the auxiliary magnetic coil 10 is adjusted to 50mm from the zinc liquid level. After completion, the furnace nose magnetic coil 21 is adjusted to 100mm from the zinc liquid level. Then the main magnetic coil 9 and the furnace nose magnetic coil 21 are used to generate plane traveling wave magnetic fields in clockwise and counterclockwise directions, and the auxiliary magnetic coil 10 generates a plane traveling wave magnetic field from the inside to the outside. The plane traveling wave magnetic field exerts a force on the liquid metal, and under the drive of the force, the liquid metal flows in a predetermined direction, so that the surface scrap metal gathers in the convergence area 23, and forms a closed magnetic area in the convergence area 23, reducing the dispersion of the surface scrap metal in the convergence area 23. When the scrap metal impurities on the surface of the zinc liquid gather, the galvanizing process begins. Due to the accumulation of impurities on the liquid surface, the galvanizing quality of subsequent galvanized products is improved. Example
