Description

Technical Field

[0001] The utility model relates to the technical field of crystallizers, in particular to a vibration structure for a high-speed continuous casting crystallizer. Background Art

[0002] The crystallizer is a continuous steel casting equipment that receives the molten steel injected from the tundish and solidifies it into a solid billet shell according to the specified cross-sectional shape. It is the most critical component of the continuous casting machine, and its structure, material and performance parameters play a decisive role in the quality of the billet and the production capacity of the casting machine.

[0003] Most vibration structures currently used are not convenient for vibrating the crystallizer, and the crystallizer cannot be lifted to replace the spring.

[0004] After searching, the existing patent [CN 211101477 U] discloses a vibration device for a cast steel crystallizer, including a bottom plate, two side baffles are fixedly installed on the left and right sides of the bottom plate, and the two side baffles are fixedly installed with guide pillars one at positions close to the bottom plate, and the other end of the guide pillar one is fixedly installed with a shock-absorbing plate. The utility model connects the cooling circuit and the vibration mechanism as a whole by installing a cooling water inlet pipe on the upper side of the vibration plate and the left side of the left crystallizer, fixing a cooling water outlet pipe on the upper side of the vibration plate and the lower right side of the right crystallizer, and fixing a cooling water connecting pipe between the left crystallizer and the right crystallizer. When the device vibrates, the cooling circuit moves together with the vibration law of the device, avoiding the cooling water pipe from being damaged and falling off, improving the cooling rate, and avoiding inconsistent amplitudes at the top of the left crystallizer and the right crystallizer through spring two, protecting the cooling water connecting pipe and reducing the equipment maintenance cost. The vibration device solves the problem that the cooling water pipe is easily damaged or falls off;

[0005] Although the above utility model patent solves the problem that the cooling water pipe is easily damaged or falls off, most of the vibration structures currently used are not convenient for vibrating the crystallizer. During use, if the crystallizer cannot be vibrated, the primary billet shell may be adhered to the crystallizer wall and be torn, which shortens the service life of the crystallizer and makes the crystallizer less practical. In addition, the crystallizer cannot be lifted to replace the spring. During use, the elasticity of the spring will decrease after long-term use. If the spring cannot be replaced, the vibration efficiency may be reduced. Utility Model Content

[0006] The utility model aims to provide a vibration structure for a high-speed continuous casting crystallizer to solve the problems raised in the prior art.

[0007] To achieve the above object, the utility model provides the following technical solution: a vibration structure for a high-speed continuous casting crystallizer, comprising a workbench, characterized in that a vibration mechanism is arranged on the top of the workbench, and the vibration mechanism comprises a motor bracket;

[0008] A motor bracket is welded to the top of the workbench, a motor is fixedly connected to one side of the motor bracket, an output shaft of the motor is fixedly connected to the motor shaft via a coupling, a rotating plate is welded to one end of the motor shaft, a moving shaft is welded to one side of the rotating plate, a fixed block is movably connected to one end of the moving shaft, a crystallizer is welded to one side of the fixed block, a fixing bar is welded to one side of the fixed block, and a spring is movably connected to the top of the workbench.

[0013] As a preferred technical solution, a clamping block is welded to one end of the second electric push rod, and a clamping groove is provided on the outer wall of the crystallizer.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model can achieve the effect of vibrating the crystallizer by setting the vibration mechanism. During use, the crystallizer is driven to vibrate up and down by starting the motor. During the up and down movement, the vibration frequency of the crystallizer can be made higher through the elastic effect of the spring, which can avoid the situation where the primary blank shell and the crystallizer wall are bonded and broken due to the inability to vibrate the crystallizer, thereby ensuring the service life of the crystallizer.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Figure 1 As shown, the utility model provides the following technical solution, including a workbench 1, a vibration mechanism 2 is arranged on the top of the workbench 1, a crystallizer 4 is movably connected to the top of the spring 208, the vertical center line of the crystallizer 4 coincides with the vertical center line of the workbench 1, and a lifting and replacement mechanism 3 is arranged on the top of the workbench 1.

[0024] Among them: after the molten steel flows into the crystallizer 4, the molten steel is strongly cooled in the crystallizer 4 and then solidified. During the solidification process, the crystallizer 4 needs to be vibrated to prevent the ingot from sticking to the copper wall of the crystallizer 4 during the solidification process, thereby preventing the shell from being torn or steel leaking. The crystallizer 4 is vibrated by the vibration mechanism 2. When the spring 208 has been used for a long time, its elasticity deteriorates. At this time, the spring 208 needs to be replaced. The spring 208 is replaced by the lifting and replacement mechanism 3, thereby completing the work.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, a vibration mechanism 2 is provided on the top of the workbench 1, and the vibration mechanism 2 includes a motor bracket 201, the motor bracket 201 is welded and connected to the top of the workbench 1, the number of the motor bracket 201 is two, a motor 202 is fixedly connected to one side of the motor bracket 201, the output shaft of the motor 202 is fixedly connected to the motor shaft 203 through a coupling, a rotating plate 204 is welded to one end of the motor shaft 203, a moving shaft 205 is welded to one side of the rotating plate 204, one end of the moving shaft 205 is movably connected to a fixed block 206, one side of the fixed block 206 is welded and connected to a crystallizer 4, a fixed bar 207 is welded to one side of the fixed block 206, the number of the fixed bars 207 is two, and a spring 208 is movably connected to the top of the workbench 1, the number of the springs 208 is four.

[0026] Among them: after the molten steel flows into the crystallizer 4, the molten steel is strongly cooled in the crystallizer 4 and then solidified. During the solidification process, the crystallizer 4 needs to be vibrated to prevent the ingot from bonding with the copper wall of the crystallizer 4 during the solidification process, thereby preventing the ingot shell from cracking or steel leakage. At this time, the motor 202 is started, and the motor 202 starts to rotate, and the motor 202 drives the motor shaft 203 to start rotating, and the motor shaft 203 drives the rotating plate 204 to start rotating, and the rotating plate 204 drives the moving shaft 205 to start rotating, so that the moving shaft 205 moves between the two fixed bars 207, and the moving shaft 205 drives the fixed bar 207 to start moving, and the fixed bar 207 drives the fixed block 206 to start moving, and the fixed block 206 drives the crystallizer 4 to start moving, so that the crystallizer 4 starts to vibrate. During the vibration process of the crystallizer 4, the frequency of vibration of the crystallizer 4 can be made higher through the action of the spring 208, thereby completing the vibration work.

[0027] like Figure 1 and Figure 4 As shown, a lifting and replacing mechanism 3 is provided on the top of the workbench 1, and the lifting and replacing mechanism 3 includes a first electric push rod 301. The first electric push rod 301 is welded on the top of the workbench 1. The number of the first electric push rods 301 is two. A connecting block 302 is welded to the top of the first electric push rod 301. A second electric push rod 303 is fixedly connected to one side of the connecting block 302. A clamping block 304 is welded to one end of the second electric push rod 303. A clamping groove 305 is opened on the outer wall of the crystallizer 4. The shape and size of the clamping groove 305 match the shape and size of the clamping block 304.

[0028] Among them: when the elasticity of the spring 208 deteriorates after a long period of use, the spring 208 needs to be replaced. First, the crystallizer 4 needs to be lifted and fixed. At this time, the second electric push rod 303 is started, so that the second electric push rod 303 begins to extend, and the second electric push rod 303 drives the block 304 to start moving, so that the block 304 is moved to the slot 305 opened inside the crystallizer 4 and is stuck. Then the first electric push rod 301 is started, so that the first electric push rod 301 begins to extend, the first electric push rod 301 drives the connecting block 302 to start rising, the connecting block 302 drives the second electric push rod 303 to start rising, the second electric push rod 303 drives the block 304 to start rising, and the block 304 drives the crystallizer 4 to start rising, so that the crystallizer 4 rises to a suitable position, and then the spring 208 is replaced manually to complete the lifting and replacement work.

[0029] The working principle of the utility model is as follows: after the molten steel flows into the crystallizer 4, the molten steel is strongly cooled in the crystallizer 4 and then solidified. During the solidification process, the crystallizer 4 needs to be vibrated to prevent the ingot from being bonded to the copper wall of the crystallizer 4 during the solidification process and causing the shell to crack or steel leakage accidents. At this time, the motor 202 is started, and the motor 202 starts to rotate, and the motor 202 drives the motor shaft 203 to start rotating, and the motor shaft 203 drives the rotating plate 204 to start rotating, and the rotating plate 204 drives the moving shaft 205 to start rotating, so that the moving shaft 205 moves between the two fixed bars 207, and the moving shaft 205 drives the fixed bar 207 to start moving, and the fixed bar 207 drives the fixed block 206 to start moving, and the fixed block 206 drives the crystallizer 4 to start moving, so that the crystallizer 4 starts to vibrate, and during the vibration process of the crystallizer 4, the frequency of the vibration of the crystallizer 4 can be increased through the action of the spring 208. The rate is higher, thereby completing the vibration work. After the spring 208 has been used for a long time, its elasticity becomes poor. At this time, the spring 208 needs to be replaced. First, the crystallizer 4 needs to be lifted and fixed. At this time, the second electric push rod 303 is started, so that the second electric push rod 303 begins to extend, and the second electric push rod 303 drives the block 304 to start moving, so that the block 304 is moved to the card slot 305 opened inside the crystallizer 4 and stuck.
