Description

Technical Field

[0001] The utility model belongs to the technical field of steel billet surface cleaning device structure, and more specifically relates to a steel billet surface cleaning device. Background Art

[0002] In the process of producing steel sections, the surface quality requirements of steel sections are relatively strict to ensure customer satisfaction with steel section products. The main problem in the processing and production of steel sections is the rough surface. The rough surface is mainly caused by the presence of local melting areas of different degrees on the surface of the steel billet in the form of points and surfaces. A large amount of oxides are attached to the matrix of the steel billet in this area. The above oxides (mainly iron oxide) cannot be eliminated after two descaling treatments. Even if the pressure is increased, it is difficult to improve, resulting in the steel billet bringing defects into the rolling mill. In the subsequent rolling process, the melting oxides have no ductility, resulting in the phenomenon of direct falling off from the pits, forming rough surfaces on the surface of the steel sections. Especially for steel sections with a large compression ratio, the rough surface area is larger, which seriously affects the forming quality of the steel sections.

[0003] At present, the oxides are mainly removed by gas blowing on the surface of the billet. However, the above method is difficult to completely remove the iron oxide scale adhering to the surface of the billet, and it is difficult to completely solve the problem of roughness on the surface of the subsequent steel section, which seriously reduces the production efficiency and affects the forming quality of the steel section.

[0024] Please also read Figures 1 to 3 , the billet surface cleaning device provided by the utility model is now described. The billet surface cleaning device comprises a conveying frame 1, a mounting column 2, an air-water blowing pipe group 3, a water supply pipe 4, an air supply pipe 5 and a supercharger 6. The conveying frame 1 is used to support the billet. The conveying frame 1 is provided with a protective cover 11 shielding the top of the billet. The mounting column 2 is connected to the upper side of the conveying frame 1 and is located at the outlet end of the protective cover 11. The air-water blowing pipe group 3 is installed on the mounting column 2 and extends to the other side of the conveying frame 1. The supercharger 6 is arranged on the air supply pipe 5. The outlet ends of the water supply pipe 4 and the air supply pipe 5 are respectively connected to the air-water blowing pipe group 3. The air-water blowing pipe group 3 is provided with a plurality of blowing nozzles 33 extending downward.

[0025] Compared with the prior art, the billet surface cleaning device provided in the present embodiment is a billet surface cleaning device. In the process of conveying the billet on the conveying frame 1, the air-water blowing pipe group 3 on the mounting column 2 can be used to blow the billet, and the air supply pipe 5 and the water supply pipe 4 are simultaneously fed into the air-water blowing pipe group 3. Under the action of the supercharger 6, the air-water blowing pipe group 3 sprays a high-pressure air-water mixture onto the surface of the billet through the blowing nozzle 33. The high-pressure blowing effect of the air-water mixture is used to effectively remove the oxides on the surface of the billet, thereby enhancing the blowing effect on the billet, improving the surface quality of the billet, and avoiding the subsequent generation of surface roughness of steel sections.

[0026] In this embodiment, the supercharger 6 is used to pressurize the air flow in the air supply pipe 5, so that the high-speed air flow is fully mixed with the water in the water supply pipe 4, and is sprayed onto the surface of the steel billet in the form of an air-water mixture under a higher pressure, so as to form a greater impact force on the steel billet, so as to break through the hot air film on the surface of the steel billet and directly hit the molten iron sheet, so that the iron oxide scale attached to the surface of the steel billet can be effectively removed, thereby obtaining a steel billet with excellent quality, avoiding the generation of roughness from the root, and effectively ensuring the quality of subsequent steel processing.

[0027] In one possible implementation, please also refer to Figures 1 to 3 The air-water blowing pipe group 3 includes an air supply transverse pipe 31 connected to the mounting column 2 and a water supply transverse pipe 32 located above the air supply transverse pipe 31. A plurality of connecting pipes 34 connected to the air supply transverse pipe 31 are provided below the water supply transverse pipe 32. The outlet end of the air supply pipe 5 is connected to the inlet end of the air supply transverse pipe 31, the water supply pipe 4 is connected to the inlet end of the water supply transverse pipe 32, and the blowing nozzle 33 is arranged below the air supply transverse pipe 31.

[0028] In this embodiment, the air-water blowing pipe group 3 adopts the form of a combination of an air supply transverse pipe 31 and a water supply transverse pipe 32, so that the air flow and the water flow are supplied synchronously and are fully mixed in the air-water blowing pipe group 3, and then sprayed onto the surface of the steel billet through the blowing nozzle 33, which can effectively remove the iron oxide in the steel billet.

[0029] Compared with the traditional method of directly using water flow for spraying, on the one hand, the air flow pressure can be effectively increased by the supercharger 6, so that the air-water mixture can impact the surface of the steel billet at a higher pressure, thereby enhancing the impact force on the steel billet. On the other hand, it can also effectively reduce the water consumption and reduce the economic cost. Therefore, the above method reduces the consumption of water resources while increasing the impact force of the air-water spray pipe group 3, and has a good use effect.

[0030] Specifically, the air supply transverse pipe 31 is connected to the top of the water supply transverse pipe 32 through the connecting pipe 34. The pressurized airflow is sent to the water supply transverse pipe 32 through the connecting pipe 34. The airflow and water are fully mixed to form an air-water mixture, which is then sprayed onto the surface of the steel billet through the blowing nozzle 33, having a good impact effect.

[0031] In some embodiments, please refer to Figures 1 to 3The connecting pipe 34 is arranged at intervals along the axial direction of the water supply transverse pipe 32, and the blowing nozzle 33 is arranged at intervals along the axial direction of the air supply transverse pipe 31. The connecting pipe 34 and the blowing nozzle 33 are arranged one by one in the vertical direction. In order to improve the mixing effect, the connecting pipe 34 is arranged at a position corresponding to the blowing nozzle 33, so that the pressurized high-pressure gas can be directly sent to the position near the blowing nozzle 33 in the water supply transverse pipe 32. The water at the blowing nozzle 33 is directly affected by the airflow in the connecting pipe 34, and can be quickly mixed with the airflow to form a gas-water mixture and sprayed on the surface of the steel billet, effectively removing the iron oxide on the surface of the steel billet.

[0032] In one possible implementation, please also refer to Figures 1 to 3 The air supply transverse pipe 31 and the water supply transverse pipe 32 are connected via a connecting block 35 . The connecting block 35 is connected to the mounting column 2 and is located on a side of the mounting column 2 close to the protective cover 11 .

[0033] In this embodiment, the air supply transverse pipe 31 and the water supply transverse pipe 32 are connected by a connecting block 35 to ensure the stability of the relative position of the air supply transverse pipe 31 and the water supply transverse pipe 32. Combined with the connecting function of the connecting pipe 34, the above components can form a unified whole. The connecting block 35 is connected to the mounting column 2 to ensure that there is an appropriate distance between the blowing nozzle 33 and the steel billet, so as to achieve effective blowing on the surface of the steel billet.

[0034] Specifically, the connection block 35 is located on a side of the mounting column 2 close to the protective cover 11, and can timely process the steel billet sent out of the protective cover 11, so that the iron oxide on the surface thereof can be effectively removed.

[0035] In some embodiments, please refer to Figures 1 to 3 The air supply transverse pipe 31 and the water supply transverse pipe 32 are respectively provided through the connection block 35 and are respectively welded to the connection block 35. The air supply transverse pipe 31 and the water supply transverse pipe 32 are respectively provided through the connection block 35 and are respectively welded to the connection block 35. The connection block 35 forms a good fixing effect between the air supply transverse pipe 31 and the water supply transverse pipe 32 to ensure the integrity of the structure.

[0036] In some embodiments, please refer to Figures 1 to 3 A sliding guide rail 21 extending in the up-down direction is provided on the mounting column 2 , and the connecting block 35 is slidably connected to the sliding guide rail 21 . The connecting block 35 is locked to the sliding guide rail 21 through a locking member 22 .

[0037] In this embodiment, the sliding guide rail 21 provided on the mounting column 2 facilitates the connection block 35 to slide up and down, thereby driving the air-water blowing pipe group 3 to adjust the up and down position, so that the distance between the blowing nozzle 33 and the steel billet meets the purging requirements. The connection block 35 is locked to the sliding guide rail 21 by the locking member 22, and even if the air-water blowing pipe group 3 is subjected to the reaction force of the air-water mixture during purging, it will not cause the problem of misalignment and movement, thereby ensuring the effective removal of iron oxide on the surface of the steel billet.

[0038] In one possible implementation, please also refer to Figures 1 to 3 There are a plurality of locking members 22, which are arranged at intervals in the up-down direction, and the locking members 22 are arranged through the connection block 35, and the extended ends of the locking members 22 abut against the sliding guide rail 21. There are a plurality of locking members 22, which can abut against different positions of the sliding guide rail 21, so as to ensure the stability of the relative position between the connection block 35 and the sliding guide rail 21, and thus make the position of the air-water spraying pipe group 3 relatively stable.

[0039] In one possible implementation, please also refer to Figures 1 to 3 The billet surface cleaning device also includes a controller and a heat detection component 7 connected to the controller. The heat detection component 7 is used to monitor the supply of the billet into the protective cover 11 to generate a detection signal and send the detection signal to the controller. The controller is electrically connected to the supercharger 6 and is used to send a boost start and stop command to the supercharger 6.

[0040] In this embodiment, a controller and a heat detection component 7 are also provided. The heat detection component 7 can timely detect the surface quality of the steel billet in the protective cover 11 and send the detection signal to the controller for the controller to make a judgment according to a preset program.

[0041] When the controller receives the detection signal that needs to be detected, it can send a boost command to the supercharger 6 according to the preset program, so that the air flow in the air supply pipe 5 has a higher pressure to meet the need to blow away the iron oxide on the surface of the steel billet.

[0042] In some embodiments, please refer to Figures 1 to 3, the heat detection component 7 is arranged on the conveying frame 1 and is located on one side of the protective cover 11. The heat detection component 7 has a detection probe 71 extending into the protective cover 11. The detection probe 71 is used to monitor the supply of the steel billet into the protective cover 11. The heat detection component 7 is arranged on the conveying frame 1 and has a detection probe 71 extending into the protective cover 11. The detection probe 71 is used to detect whether there is a steel billet entering the protective cover 11, and a detection signal is generated and sent to the controller, so that the controller can supply water and gas according to the conveying state of the steel billet. The layout structure of the above-mentioned detection probe 71 can open and close the gas-water blowing pipe group 3 according to the supply of the steel billet, avoiding the waste of water resources and electricity resources, and realizing the accuracy of the controller's control over the components such as the supercharger 6.
