Description

Technical Field

[0002] In the field of iron and steel metallurgical industry, steelmaking is a very important link, and slag removal technology is an important part of the steelmaking process.

[0003] The degree of slag removal not only affects the quality of downstream molten steel, but also affects the production cost and benefits of steel enterprises. The new generation of slag removal technology has been automated, and usually no longer requires worker operation. The slag removal process is controlled by machines throughout. However, in the later stage of automatic slag removal by the machine, the slag surface becomes thin, and the slag blocks are constantly free on the surface of the molten iron, which reduces the slag removal efficiency. At this time, manual intervention is required to operate the air-blowing slag removal device to lower the gun, insert it obliquely into the liquid surface of the molten iron tank, and spray nitrogen into the molten iron, so that the rolling liquid surface forces the free slag behind the molten iron tank to move and gather at the tank mouth, which is convenient for the machine to automatically remove the slag. However, the gun lowering speed, gun lowering angle and gun lowering depth are all based on the operator's experience and judgment, resulting in a long gun lowering time, affecting the efficiency of air-blowing slag removal and subsequent processes, and thus affecting steelmaking efficiency.

[0042] In order to solve the technical problem in the prior art that the air slag removal gun 20 is not accurately controlled and affects the air slag removal efficiency and steelmaking efficiency, the present application provides an air slag removal device, which is convenient for accurately detecting and controlling the gun lowering angle, gun lowering depth and gun lowering speed, improving the gun lowering accuracy of the air slag removal gun 20, and thus improving the air slag removal efficiency and steelmaking efficiency. The first end of the guide bracket 10 referred to in the present application refers to the upper end of the guide bracket 10 away from the ladle 002 and the molten iron liquid level, and the second end of the guide bracket 10 refers to the lower end of the guide bracket 10 close to the ladle 002 and the molten iron liquid level.

[0043] See also Figure 1 and Figure 4 The air slag removal device provided in the embodiment of the present application includes a guide bracket 10, an air slag removal gun 20, a first drive mechanism 30, a second drive mechanism 40, a displacement detection assembly 70 and an inclination detection assembly 80. The guide bracket 10 is generally in the shape of a long strip, and is used to support the air slag removal gun 20 and guide the movement of the air slag removal gun 20. The air slag removal gun 20 is slidably arranged with the guide bracket 10, and the air slag removal gun 20 is generally parallel to the guide bracket 10. The first end of the guide bracket 10 is supported by a rotating shaft, so that the guide bracket 10 and its second end can rotate around the rotating shaft of the first end to adjust the angle of the guide bracket 10.

[0044] The first driving mechanism 30 is disposed on the guide bracket 10, and is used to drive the air slag gun 20 to reciprocate relative to the guide bracket 10, so that the air slag gun 20 is extended or retracted relative to the second end of the guide bracket 10, and the depth of the air slag gun 20 inserted into the molten iron liquid surface is controlled by adjusting the extension length of the air slag gun 20. When the first driving mechanism 30 is used to drive the air slag gun 20 to move relative to the guide bracket 10, the displacement detection component 70 can directly or indirectly detect the movement displacement of the air slag gun 20 relative to the guide bracket 10, and it is convenient to determine the depth of the air slag gun 20 according to the movement displacement of the air slag gun 20 relative to the guide bracket 10. By paying attention to the displacement change of the air slag gun 20 at all times, the lowering speed of the air slag gun 20 can be controlled.

[0045] The second driving mechanism 40 is connected to the guide bracket 10, and can drive the guide bracket 10 to rotate around the rotating shaft at its first end during movement, adjust the angle of the guide bracket 10, and then adjust the lowering angle of the air-blowing slag-removing gun 20. With the help of the inclination detection component 80, the inclination of the guide bracket 10 is accurately detected and controlled, so that the air-blowing slag-removing gun 20 is easily controlled to be inserted into the molten iron liquid surface at a set angle, that is, the accurate control of the lowering angle of the gun is realized.

[0046] In some embodiments, in conjunction with Figures 1 to 3, the first driving mechanism 30 adopts the form of a combination of a driving motor 31 and a transmission assembly. Among them, the driving motor 31 is fixed to the first end of the guide bracket 10, and the transmission assembly is extended along the length direction of the guide bracket 10. The transmission assembly plays the role of connecting the driving motor 31 and the air-blowing slag-removing gun 20. The transmission assembly is provided with an input end and an output end. The input end of the transmission assembly is connected to the output shaft of the driving motor 31, and the output end of the transmission assembly is fixedly connected to the air-blowing slag-removing gun 20. The transmission assembly can convert the rotation of the input end into the linear motion of the output end, thereby driving the air-blowing slag-removing gun 20 to slide relative to the guide bracket 10. By controlling the forward and reverse angles of the driving motor 31, the movement direction and movement displacement of the air-blowing slag-removing gun 20 can be controlled.

[0047] A reducer or a reduction mechanism may be provided between the output shaft of the driving motor 31 and the input end of the transmission assembly as required, so as to improve the control accuracy of the movement displacement of the air-blowing slag-removing gun 20 .

[0048] Exemplarily, the guide bracket 10 is provided with a guide slot along its extension direction, and the transmission assembly adopts a structure in which a transmission gear, a transmission chain 32 and a guide slider 33 cooperate, and the transmission assembly also includes a plurality of driven gears for supporting the transmission chain 32. The transmission chain 32 is a closed annular structure, and the transmission gear is fixedly mounted on the output shaft of the driving motor 31 and meshes with the transmission chain 32. The driving motor 31 drives the transmission gear to rotate and then drives the transmission chain 32 to move. A plurality of driven gears are provided as needed and are rotatably mounted on the guide bracket 10, and the driven gear is meshed with the transmission chain 32 to support and guide the transmission chain 32.

[0049] The guide slider 33 is slidably arranged in the guide chute, and at least two groups of guide sliders 33 are arranged. The air-blowing slag-removing gun 20 is fixedly installed on the guide slider 33, and the guide slider 33 and the guide chute cooperate to realize sliding guidance. The guide slider 33 is fixedly provided with a plurality of driving teeth, and the driving teeth are meshed with the transmission chain 32. The transmission chain 32 moves under the drive of the transmission gear and drives the guide slider 33 to move along the guide chute through the driving teeth, thereby driving the air-blowing slag-removing gun 20 fixed on the guide slider 33 to move.

[0050] The displacement detection component 70 can directly detect the movement of the guide slider 33 or the movement of the air slag gun 20 to detect the movement displacement of the air slag gun 20, and can also indirectly detect the movement displacement of the guide slider 33 and the air slag gun 20 by detecting the rotation angle of the drive motor 31. In this embodiment, the displacement detection component 70 uses an encoder set at the drive motor 31. The encoder can be mechanical, optical, magnetic or electromagnetic induction as needed, and this application does not limit this.

[0051] In some embodiments, the air slag removal device also includes a controller 60 and a display module. The encoder is connected to the controller 60, and the controller 60 is connected to the display module. The controller 60 includes at least a storage module and a processing module. The storage module is used to store the corresponding relationship between the rotation angle of the drive motor 31 and the movement displacement of the air slag removal gun 20. The processing module receives the rotation angle information of the drive motor 31 detected by the encoder, outputs the actual movement displacement of the air slag removal gun 20 by reading the corresponding relationship between the rotation angle of the drive motor 31 and the movement displacement of the air slag removal gun 20 stored in the storage module, and transmits the actual movement displacement to the display module for real-time display.

[0052] Further, the second driving mechanism 40 includes a fixed support 41 and an electro-hydraulic push rod 42, the first end of the electro-hydraulic push rod 42 is connected to the fixed support 41, and the second end, i.e., the end of the electro-hydraulic push rod 42, is hinged to the second end of the guide bracket 10, and the second end of the guide bracket 10 is driven to rotate around the rotating shaft by the extension and contraction of the electro-hydraulic push rod 42, thereby changing the inclination angle of the guide bracket 10 and adjusting the lowering angle of the air-blowing slag-removing gun 20. The inclination detection component 80 can directly detect the inclination angle of the guide bracket 10 or the air-blowing slag-removing gun 20, and can also indirectly detect the lowering angle of the air-blowing slag-removing gun 20 by detecting the extension and contraction amount of the electro-hydraulic push rod 42.

[0053] In this embodiment, the inclination detection component 80 includes at least a displacement sensor for detecting the extension and retraction amount of the electro-hydraulic push rod 42. The displacement sensor is connected to the above-mentioned controller 60. The controller 60 stores the correspondence between the extension and retraction amount of the electro-hydraulic push rod 42 and the inclination angle of the guide bracket 10. The displacement sensor transmits the detected extension and retraction amount of the electro-hydraulic push rod 42 to the controller 60. The controller 60 processes the stored correspondence between the extension and retraction amount of the electro-hydraulic push rod 42 and the inclination angle of the guide bracket 10 to obtain the actual inclination angle of the guide bracket 10, and transmits the actual inclination angle to the display module for display.

[0054] In addition, the inclination detection assembly 80 can also use an inclination sensor set on the guide bracket 10, and use the inclination sensor to directly detect the inclination of the guide bracket 10. Or the inclination detection assembly 80 includes a displacement sensor for detecting the extension and contraction amount of the electro-hydraulic push rod 42 and a inclination sensor for directly detecting the inclination of the guide bracket 10. The displacement sensor and the inclination sensor are used to improve the inclination detection accuracy of the guide bracket 10, so that the operator can accurately adjust the inclination of the guide bracket 10 according to the actual inclination information of the guide bracket 10 detected, thereby improving the precise control of the lowering angle of the air blast slag driving gun 20.

[0055] The second driving mechanism 40 is not limited to the structure of the fixed support 41 and the electro-hydraulic push rod 42, and may also adopt a combination structure of the fixed support 41 and the hydraulic cylinder or the fixed support 41 and the electric push rod.

[0056] On the basis of the above-mentioned embodiments, the air slag removal device provided in the embodiments of the present application includes a controller 60, and the controller 60 is connected to the first drive mechanism 30, the second drive mechanism 40, the displacement detection component 70 and the inclination detection component 80, so that the controller 60 adjusts the operation of the first drive mechanism 30 and the second drive mechanism 40 according to the movement displacement of the air slag removal gun 20 detected by the displacement detection component 70 and the inclination of the guide bracket 10, so as to adjust the gun lowering angle, gun lowering displacement and gun lowering speed, realize automatic control of the air slag removal gun 20, improve control accuracy, and thus improve the air slag removal efficiency.

[0057] Furthermore, the air-blowing slag-removing device also includes a visual camera 50, which is fixed above the molten iron liquid surface and connected to the controller 60. The ladle transfer vehicle 001 transports the ladle 002 to the bottom of the air-blowing slag-removing device, and the air-blowing slag-removing gun 20 is driven toward the molten iron liquid surface. When the gun head just contacts the molten iron liquid surface, smoke and dust will be stirred up. The visual camera 50 can monitor the smoke and dust stirred up when the gun head of the air-blowing slag-removing gun 20 contacts the molten iron liquid surface, and mark the insertion depth of the air-blowing slag-removing gun 20 at this moment as zero. When the air-blowing slag-removing gun 20 moves from the first end to the second end relative to the guide bracket 10, the insertion depth increases, and when the air-blowing slag-removing gun 20 moves from the second end to the first end relative to the guide bracket 10, the insertion depth decreases. In addition, the visual camera 50 is also used to identify and determine whether the ladle 002 and the ladle transfer vehicle 001 have reached the bottom of the air-blowing slag-removing gun 20.

[0058] In some embodiments, the air-blowing slag-removing device is further provided with a distance sensor 90, which is fixed to the air-blowing slag-removing gun 20 and is at a preset distance L0 from the gun head of the air-blowing slag-removing gun 20, and the preset distance L0 is greater than the maximum insertion depth of the air-blowing slag-removing gun 20 into the molten iron liquid surface. The distance sensor 90 is used to detect the distance between the air-blowing slag-removing gun 20 and the molten iron liquid surface, and the distance detected by the distance sensor 90 from the molten iron liquid surface is set as P, and P minus L0 is the distance between the gun head of the air-blowing slag-removing gun 20 and the molten iron liquid surface. The controller 60 is connected to the distance sensor 90, and is used to obtain the distance L between the gun head of the air-blowing slag-removing gun 20 and the molten iron liquid surface according to the distance P detected by the distance sensor 90 and the molten iron liquid surface and the preset distance L0. So as to control the gun lowering depth and gun lowering speed of the air-blowing slag-removing gun 20 according to the distance L between the gun head of the air-blowing slag-removing gun 20 and the molten iron liquid surface and the movement displacement of the air-blowing slag-removing gun 20.

[0059] Exemplarily, when L≥0.5m, the controller 60 controls the first driving mechanism 30 to drive the air-blowing slag-removing gun 20 to move toward the molten iron surface at a speed of 0.8m / s;

[0060] When 0≤L<0.5m, the controller 60 controls the first driving mechanism 30 to drive the air-blowing slag-removing gun 20 to move toward the molten iron surface at a speed of 0.5m / s;

[0061] After the air-blowing slag-removing gun 20 is inserted into the molten iron surface, that is, after the controller 60 learns that the visual camera 50 monitors the smoke and dust stirred up by the gun tip of the air-blowing slag-removing gun 20 contacting the molten iron surface, the controller 60 controls the first driving mechanism 30 to drive the air-blowing slag-removing gun 20 to be inserted into the molten iron surface at a speed of 0.3 m / s until the set insertion depth is reached.

[0062] The air slag removal device provided in the present application adjusts the lowering speed and displacement of the air slag removal gun 20 through the first driving mechanism 30, adjusts the lowering angle of the air slag removal gun 20 with the help of the second driving mechanism 40 and the guide bracket 10, and uses the displacement detection component 70 and the inclination detection component 80 to detect the lowering depth and angle of the air slag removal gun 20 in real time, thereby improving the control accuracy of the lowering of the air slag removal gun 20. By controlling the movement of the first driving mechanism 30 and the second driving mechanism 40 with the help of the controller 60, the lowering efficiency of the air slag removal gun 20 can be significantly improved and the lowering time can be shortened.

[0063] The above-mentioned air slag removal device can improve the gun lowering efficiency of the air slag removal gun 20, accurately control the gun lowering depth, gun lowering speed and gun lowering angle, so that the nitrogen injection effect is significant, the slag gathering effect is improved, and the slag removal efficiency is improved; by shortening the gun lowering time, the erosion of the gun head of the air slag removal gun 20 by molten iron is reduced. It is convenient for the automatic slag removal device 003 to quickly complete the slag removal and improve the steelmaking efficiency. The controller 60 automatically controls the first drive mechanism 30 and the second drive mechanism 40 to drive the air slag removal gun 20 to move according to the position vision camera 50, the displacement detection component, the inclination detection component 80 and the distance sensor 90, which reduces the labor intensity and labor cost.
