Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, and in particular to an automatic spraying device for billets in a continuous casting machine. Background Technology

[0002] With the continuous development of technology, the development of heavy industry has also increased. Heavy industry mainly involves the processing and production of steel. After molten steel initially solidifies in the crystallizer to form a billet shell, it is pulled out of the crystallizer and enters the secondary cooling zone. Spraying rapidly cools the surface of the billet, allowing the liquid steel inside to continue solidifying. This forms a solidified billet shell of a certain thickness and strength in a short time, meeting the requirements of subsequent production processes. Spraying ensures a uniform temperature drop across the billet surface, preventing localized overheating or undercooling. Uniform cooling allows for even growth of the internal microstructure of the billet, preventing microstructural differences caused by uneven cooling and improving the overall quality of the billet.

[0003] Most existing steel cooling sprays use direct spraying, which has a simple nozzle position and structure. Multiple sets are needed to spray and cool the steel from multiple directions and at multiple different points. This can lead to abnormal problems inside the steel, and the recovery of the cooling medium can be quite difficult. Utility Model Content

[0004] This disclosure relates to an automatic spraying device for continuous casting machine billets. After the conveying device transports the billet, the billet is formed by the conveying device and then guided into the inner end of the collecting component. The supporting component inside the collecting component supports the control component, allowing the nozzle component of the control component to spray the passing billet, thereby achieving a heat dissipation effect on the billet. The head of the nozzle component can spray at an angle, causing the device to rotate due to a reverse impact, thus achieving circumferential spray cooling.

[0005] In a first aspect, this disclosure provides an automatic spraying device for billets in a continuous casting machine, specifically comprising: a conveying device; a collecting component is provided at the right side of the conveying device, a billet is clamped and conveyed inside the conveying device, a supporting component is mounted at the inner end of the collecting component, a rotating component is rotatably mounted at the middle of the supporting component, the billet is placed at the middle of the rotating component, a control component is mounted at the left side of the inner wall of the rotating component, and a nozzle assembly is mounted at the right side of the inner wall of the rotating component, the control component and the nozzle assembly are interconnected.

[0006] In at least some embodiments, the bottom collection cover of the collection assembly is installed on the right side of the billet, and a top cover is installed on the top of the bottom collection cover. A hole is provided in the middle part of the contact position between the top cover and the bottom collection cover, and a barrier curtain is provided on the hole.

[0007] In at least some embodiments, the support frame of the support component is placed in the middle of the inside of the collection component, a top clip is snapped onto the top of the support frame, three sets of openings are provided at the bottom of the support frame, a supply frame is installed at the contact position between the support frame and the top clip, an outer pipe is provided at the corresponding installation position at the outer end of the supply frame, and a cavity is provided inside the supply frame, which is connected to the outer pipe.

[0008] In at least some embodiments, the outer retaining ring of the rotating component is sleeved and installed on the inner side of the support component. A positioning ring is screwed and installed on the left side of the outer retaining ring. An auxiliary wheel is rotatably installed at the position where the positioning ring contacts the support component. An auxiliary groove is provided at the outer end of the outer retaining ring and the positioning ring. An inner guide groove is provided on the inner end face of the outer retaining ring. An inner cavity is provided at the inner end of the outer retaining ring.

[0009] In at least some embodiments, the control ring of the control component is rotatably mounted on the left side of the inner end of the rotating component, the sliding frame of the control component is slidably mounted on the inner guide groove of the rotating component, the outer end of the sliding frame contacts the spiral groove of the control ring, a connecting block is connected between the sliding frame and the nozzle assembly, and a control block is added to the outer end of the rotational mounting position of the control ring.

[0010] In at least some embodiments, the inner frame of the nozzle assembly is configured as a ring structure, and the bottom nozzle disposed on the inner frame is connected to it, with the head outlet shape of the bottom nozzle being inclined.

[0011] This utility model provides an automatic spraying device for billets in a continuous casting machine, which has the following beneficial effects:

[0012] In this invention, the conveying device clamps and conveys the billet to a rotating assembly mounted on a support component. A circular array of nozzles is installed at the inner end of the rotating assembly, and a control component is connected to the nozzle assembly. When adjusted, the control component swings the nozzles in an inclined direction, creating a conical spray pattern. The tilted head of the nozzles directs the spray, causing the billet to pass through them. This creates a counterforce, causing the rotating assembly to rotate, thus improving heat dissipation for the billet. A collection component is installed at the outer end of the support component, covering the area sprayed by the nozzles to prevent the spread of debris and facilitating recycling.

[0013] In addition, when the device is running, the coolant used for cooling will be sprayed out, causing the liquid to atomize and diffuse. The bottom collection hood and the top hood are interlocked to block the atomized coolant and facilitate its collection. The holes in the bottom collection hood and the top hood allow the casting billet to pass through, and the barrier curtain at the hole is in contact with the casting billet. While the barrier curtain is in contact with the casting billet, it further blocks the mist, facilitating the collection of the mist and preventing its diffusion.

[0014] Furthermore, the device needs to be rotated during use to engage the outer retaining ring with the inner end of the support component. A positioning ring is screwed onto the left side of the outer retaining ring for limiting its position. Auxiliary wheels are installed on the inner end faces of both the outer retaining ring and the positioning ring. These auxiliary wheels assist in better rotating the entire rotating component within the support component. Auxiliary grooves are provided on the outer ends of the outer retaining ring and the positioning ring to facilitate easier assembly and disassembly of the rotating component. Firstly, the inner guide groove on the inner end face of the outer retaining ring allows for easy control of the sliding installation of the component parts. The nozzle assembly is installed inside the rotating component. Therefore, to allow the support component to supply the nozzle assembly, an inner cavity is directly provided inside the outer retaining ring, allowing the support component to supply the nozzle assembly through the inner cavity.

[0015] In addition, during use, the mechanical energy of the control block is directly controlled to make the control ring rotate, while the sliding frame slides on the inner guide groove. The rotating control ring drives the sliding frame through the spiral groove, realizing the sliding control of the sliding frame by the control ring. The sliding frame controls the nozzle assembly through the connecting block, realizing the angle swing of the nozzle assembly, thus achieving the control function of the nozzle assembly.

[0016] Furthermore, the ring-shaped structure of the inner frame allows it to rotate and adjust within the rotating assembly, while also supplying coolant from both ends. The outlet of the bottom nozzle is set at an angle, causing the mist sprayed from the bottom nozzle to be angled, thereby creating a reverse force in the device and enabling automatic rotation of the device, thus achieving better cooling of the casting billet.

In order to supply the rotating component 5, the cavity inside the supply frame 403 is directly connected to the outer pipe 404, thereby realizing the connection between the outer pipe 404 and the supply frame 403, which plays the role of supplying the rotating component 5.

[0041] In this embodiment of the disclosure, such as Figure 3 Figure 6 As shown, the outer retaining ring 501 of the rotating component 5 is sleeved and installed on the inner side of the support component 4.

At the same time, the auxiliary wheel 503 is installed on the inner end face of both the outer retaining ring 501 and the positioning ring 502.

The support component 4 rotates, and the outer ends of the outer retaining ring 501 and the positioning ring 502 are provided with auxiliary grooves 504 to facilitate the disassembly and assembly of the rotating component 5. The inner end face of the outer retaining ring 501 is provided with an inner guide groove 505, and the inner end of the outer retaining ring 501 is provided with an inner cavity 506. First, the inner guide groove 505 provided on the inner end face of the outer retaining ring 501 facilitates the sliding installation of the component 6 through the inner guide groove 505. The nozzle component 7 will be installed on the inner end of the rotating component 5. Therefore, in order to allow the support component 4 to supply the nozzle component 7, the inner cavity 506 is directly provided inside the outer retaining ring 501, so that the support component 4 can supply the nozzle component 7 through the inner cavity 506.

[0042] In this embodiment of the disclosure, such as Figure 5 Figure 7 As shown, the control ring 601 of the control component 6 is rotatably mounted on the left side of the inner end of the rotating component 5. The sliding frame 602 of the control component 6 is slidably mounted on the inner guide groove 505 of the rotating component 5. The outer end of the sliding frame 602 contacts the spiral groove of the control ring 601. A connecting block 603 connects the sliding frame 602 and the nozzle assembly 7. A control block 604 is added to the outer end of the rotating mounting position of the control ring 601. In use, the mechanical energy of the control block 604 is directly controlled to make the control ring 601 rotate, while the sliding frame 602 slides on the inner guide groove 505. The rotating control ring 601 transmits power to the sliding frame 602 through the spiral groove, realizing the sliding control of the sliding frame 602 by the control ring 601.

Firstly, the ring structure of the inner frame 701 allows the inner frame 701 to rotate and adjust within the rotating assembly 5, and also allows the inner frame 701 to supply coolant from both ends. Secondly, the outlet of the bottom nozzle 702 is set to be inclined, so that the mist sprayed by the bottom nozzle 702 is inclined, thereby making the device generate a reverse force, realizing the automatic rotation of the device, and better realizing the cooling effect on the casting billet 2.

[0044] The working principle of this embodiment is as follows: During installation, the collecting component 3 is first turned on. The tool needs to adjust the position control block 604 of the control component 6 so that the control block 604 controls the control ring 601. The control ring 601 will swing the angle of the nozzle component 7 through the sliding frame 602, so that the nozzle component 7 forms a specified conical spray shape. The conveying device 1 clamps and conveys the billet 2 to the middle position of the rotating component 5. At this time, the external pipe 404 of the external support component 4 is connected to the pipeline, so that the support component 4 supplies coolant to the rotating component 5. At this time, the collecting component 3 is closed, so that the billet 2 is introduced into the inner end position of the rotating component 5. The rotating component 5, which is supplied with coolant, will spray out from the nozzle component 7. The nozzle component 7 rotates while spraying out at an angle, forming a uniformly rotating cooling surface. The collecting component 3 has the function of collecting mist, etc.
