[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] Example 1

[0024] The problem to be solved is that existing hot-rolled coils have residual impurities on their surface, which affect the quality of the hot-rolled coils. Workers need to remove the impurities from the hot-rolled coils separately, which leads to slow and incomplete impurity removal efficiency.

[0025] The solution is as follows: A finishing device for hot-rolled coils of ferrous metal smelting and rolling, comprising a device body 1, the device body 1 including a first support device 2, a second support device 3, a flame cleaning device 4, and a base 5. The first support device 2 and the second support device 3 are distributed in a horizontally equidistant manner. The flame cleaning device 4 is installed between the tops of the first support device 2 and the second support device 3. A set of bases 5 is provided, and a set of bases 5 are respectively welded to the bottoms of the first support device 2 and the second support device 3. The flame cleaning device 4 includes a flame mounting block 6 and a gas torch 7. Two sets of gas torches 7 are installed on flame mounting blocks 6 in a horizontally equidistant manner. The flame mounting blocks 6 have a rectangular structure and two sets of horizontally equidistant embedding ports 8 are provided on the rear side of the flame mounting blocks 6. Damping mounting shafts 9 are provided at both ends of the flame mounting blocks 6. The gas torches 7 include a gas pipe 10, a gas flame nozzle 11, and a gas connecting hose 13. The gas flame nozzle 11 is installed at the front end of the gas pipe 10. A flow control valve 12 is installed inside the gas pipe 10. The gas connecting hose 13 is installed at the rear end of the gas pipe 10.

[0026] Analysis of the above content: The flame cleaning device 4 uses a gas torch 7 to spray a high-temperature flame to burn and clean impurities such as oxide scale and oil stains on the surface of the hot-rolled coil. The specific process is as follows: Gas enters the gas pipeline 10 through the gas connection hose 13; the flow control valve 12 adjusts the gas flow to control the flame intensity; the gas is finally ejected from the gas flame nozzle 11 to form a flame; the flame mounting block 6 is connected to the bearing mounting ports 21 of the first support device 2 and the second support device 3 via a damping mounting shaft 9, and can rotate around the damping mounting shaft 9 to adjust the flame spray angle. When the impurities on the coil surface are thick: rotating the flow control valve 12 increases the gas flow, thus increasing the flame intensity ejected from the gas flame nozzle 11. Simultaneously, rotating the flame mounting block 6 allows the flame to form a 45° angle with the coil surface (enhancing the burning impact force). When the impurities on the coil surface are thick... When the impurity is thin: reduce the opening of the flow control valve 12 to decrease the flame intensity. Rotate the flame mounting block 6 until the flame is parallel to the surface of the roll plate (to avoid excessive burning and damage to the roll plate). When changing the gas source: disconnect the gas connecting hose 13 from the gas source, and reconnect it after replacement. The flame intensity can be precisely adjusted through the flow control valve 12 to adapt to the cleaning needs of roll plates with different impurity thicknesses. The flame mounting block 6 can be flexibly adjusted in angle (0-90°) through the damping mounting shaft 9 to adapt to roll plates of different widths and curvatures. The two sets of gas torches 7 are equidistantly distributed laterally, which can clean different areas of the roll plate simultaneously, improving cleaning efficiency. Gas flow rate adjustment range: 0.5-3m 3 / h (achieved via flow control valve 12), flame mounting block rotation angle range: 0-90° (damped mounting shaft 9 provides damping positioning), gas flame nozzle 11 spray distance: 100-300mm (adapted to the distance between the roll plate and the device).

[0027] Example 2:

[0028] Please see Figure 1-4 This utility model provides a technical solution based on Embodiment 1: The first support device 2 and the second support device 3 both include a main support block 14, a guide connecting block 15, and an insertion bolt 16. The top of the main support block 14 is provided with a large movable groove 17, and both ends of the large movable groove 17 are provided with small movable grooves 18. The guide connecting block 15 is inserted into the large movable groove 17, and both ends of the guide connecting block 15 are provided with small sliding blocks 20. The surfaces of the main support block 14 and the guide connecting block 15 are provided with several sets of locking adjustment holes 19 distributed in a row at equal intervals. The insertion bolt 16 has an L-shaped structure and is inserted into the locking adjustment holes 19 of the main support block 14 and the guide connecting block 15. The top side of the guide connecting block 15 is provided with a bearing mounting port 21.

[0029] Analysis of the above content: The height of the flame cleaning device 4 can be adjusted by the guide connecting block 15 sliding up and down in the large movable groove 17 of the main support block 14; after adjustment, the insert pin 16 passes through the locking adjustment hole 19 of the main support block 14 and the guide connecting block 15 to fix the two. The small sliding block 20 slides within the small movable groove 18 to ensure the vertical lifting and lowering of the guide connecting block 15. The bearing mounting port 21 is used to install the damping mounting shaft 9, enabling the rotational connection of the flame mounting block 6. When the thickness of the rolled plate is 5-10mm: pull the guide connecting block 15 upward to move the small sliding block 20 upward within the small movable groove 18 until the distance between the flame cleaning device 4 and the rolled plate is 150-200mm. Then insert the insertion bolt 16 into the corresponding locking adjustment hole 19 for fixation. When the thickness of the rolled plate is 10-20mm: push the guide connecting block 15 downward to adjust the distance to 200-300mm and fix it with the insertion bolt 16. If the guide connecting block 15 slides and gets stuck: check the fit clearance between the small sliding block 20 and the small movable groove 18 (normally 0.1-0.3mm), and add grease if necessary.

[0030] Example 3:

[0031] Please see Figure 1-4 The present invention provides a technical solution based on Embodiment 1: the base 5 has a rectangular structure, the top of the base 5 has two sets of symmetrically distributed elongated groove fixing holes 24, the base 5 has a reinforcing opening 22 inside, the reinforcing opening 22 has a rectangular structure, and the base 5 has several sets of horizontally equidistant reinforcing blocks 23 inside, the reinforcing blocks 23 have a trapezoidal structure.

[0032] Analysis of the above content: The base 5 is connected to the ground expansion bolts through the long slot fixing hole 24 to fix the whole device; the internal reinforcing port 22 and the trapezoidal reinforcing block 23 form a grid-like reinforcing structure, which improves the load-bearing capacity and deformation resistance of the base. When installed on a cement floor: the expansion bolts are passed through the long slot fixing hole 24 and the nuts are tightened to fix it. If the ground is uneven, the position of the base 5 can be finely adjusted by the length margin (50mm) of the long slot fixing hole 24. The long slot fixing hole 24 is adapted to ground fixing points with different spacing, which is highly flexible in installation. The combination of the trapezoidal reinforcing block 23 and the reinforcing port 22 reduces the weight of the base while improving the structural strength (the load-bearing capacity is increased by 40%).

[0033] Example 4:

[0034] Please see Figure 1-4The present invention provides a technical solution based on Embodiment 1: A connecting arm 25 is provided between the first support device 2 and the second support device 3. The connecting arm 25 has a rectangular structure. Several sets of main structural holes 26 are distributed in a horizontally equidistant manner on the surface of the connecting arm 25. The main structural holes 26 have a rectangular structure. A structural block 27 is provided inside the main structural hole 26. The structural block 27 has a triangular shape. Small structural holes 28 are provided inside the structural block 27. The small structural holes 28 have a triangular shape.

[0035] Analysis of the above content: Connecting arm 25 connects the first support device 2 and the second support device 3. The main structural hole 26 reduces the overall weight. The triangular structural block 27 and the triangular small structural hole 28 form a stable triangular support structure, which enhances the connection rigidity of the two support devices and avoids relative displacement due to vibration during operation. When the device vibrates greatly during operation: check the weld between the structural block 27 and the main structural hole 26 (the weld strength must be ≥200MPa). If cracks are found, they need to be re-welded. The combination of the main structural hole 26 and the structural block 27 reduces the weight of connecting arm 25 by 30% while increasing the bending strength by 25%. The triangular small structural hole 28 further optimizes the stress distribution and reduces the impact of resonance.
