TECHNICAL FIELD
[0001] The present application relates to the technical field of a billet caster vibration device, and in particular to a crystallizer vibration device for a billet caster. BACKGROUND
[0002] At present, the billet caster is one of the important equipment in modern steel production, mainly used for continuous casting of liquid metal into semi-finished products with certain shape and size. The crystallizer vibration device, as a key component of the billet caster, directly affects the quality and production efficiency of the cast billet. In recent years, with the continuous development and technological progress of the metallurgical industry, the requirements for the crystallizer vibration device are becoming higher and higher, especially in improving the surface quality of the cast billet, reducing cracks and inclusions, etc. Significant progress has been made.
[0003] In the existing billet caster, in order to solve the quality problem of liquid metal during solidification in the crystallizer, various vibration methods are usually used to improve the forming conditions of the cast billet. Common vibration methods include mechanical vibration, electromagnetic vibration, etc. Specifically, mechanical vibration generally drives the screw nut pair or other transmission mechanisms through the motor, so that the vibration table reciprocates up and down; while electromagnetic vibration directly acts on the vibration table by electromagnetic force to realize periodic vibration. These methods can effectively improve the surface quality and internal organization of the cast billet to a certain extent, but also have some shortcomings.
[0004] However, the crystallizer vibration device for the billet caster in the prior art generally has low vibration precision and poor stability. For example, in the mechanical vibration system, due to the long transmission chain, cumulative error is easy to occur, which causes the actual motion trajectory of the vibration table to deviate from the expected path, thereby affecting the quality of the cast billet. In addition, after long time running, the wear between components will be aggravated, further reducing the reliability and service life of the system. Therefore, a crystallizer vibration device capable of accurately controlling the motion trajectory of the vibration table and having high stability is needed. CONTENT OF THE INVENTION
[0005] In order to solve the above problems, the present application provides a crystallizer vibration device for a billet caster.
[0006] The crystallizer vibration device for a billet caster provided by the present application adopts the following technical scheme:
[0007] A kind of bloom continuous casting machine with crystallizer vibration device, including crystallizer, also including vibration table, guiding component is provided in vibration table, guiding component includes mounting plate, screw rod and guide rod, mounting plate is horizontally arranged, and crystallizer is detachably connected with mounting plate, screw rod is vertically arranged, and screw rod is rotatably connected with vibration table, guide rod is vertically fixed with vibration table, one end of mounting plate is threadedly connected with screw rod, and the other end is slidably connected with guide rod, the bottom of vibration table is provided with driving device for driving vibration table to vibrate up and down.
[0008] By adopting the above technical scheme, the crystallizer can be quickly installed with the mounting plate in the vibration table, and then rotated through the screw rod in the guiding component, so that the mounting plate and the crystallizer are adjusted in the vertical direction until they are fixed at the appropriate position. The driving device at the bottom of the vibration table drives the vibration table to vibrate up and down. At this time, the vibration table and the crystallizer both have a certain vibration amplitude in the vertical direction. Moreover, the crystallizer can reduce the deviation in the horizontal direction under the limiting and guiding action of the screw rod and the guide rod, thereby improving the vibration stability of the crystallizer.
[0009] Optionally, a plurality of legs are fixed to the bottom of the vibration table, and the plurality of legs are uniformly distributed along the area of the bottom of the vibration table, and each leg is fixed with a damping seat.
[0010] By adopting the above technical scheme, the legs at the bottom of the vibration table and the damping seats fixed below the legs can effectively reduce the vibration amplitude of the vibration table and increase the stability of the vibration table.

[0012] By adopting the above technical scheme, when the driving motor is started, the driving motor drives the turntable to rotate. When the turntable rotates, it drives the connecting rod to make circular motion. The end of the connecting rod connected with the moving column drives the moving column to slide in the slide rail. Since the slide rail is fixed in the vertical direction, the moving column drives the vibration table to vibrate in the vertical direction, thereby reducing the deviation in the horizontal direction and increasing the stability of the vibration table.
[0013] Optionally, a spring and a limit alarm are respectively fixed at both ends of the slide rail. When the moving column slides in the slide rail, it abuts against the spring. When the spring is compressed to a certain degree, the limit alarm is triggered.
[0014] By adopting the technical scheme, the mobile column is abutted against the spring when sliding to a certain range in the slide rail, which can reduce vibration, and the vibration of the vibration table is stopped when the vibration amplitude of the mobile column exceeds the range of the limit alarm, so that the vibration amplitude of the vibration table is prevented from being too large, and the safety of the vibration of the vibration table is increased.
[0015] Optionally, two support frames are fixed on the side wall of the slide rail, the support frames are fixed on the motor base, and the two support frames are symmetrically arranged along the slide rail.
[0016] By adopting the technical scheme, the support frames arranged symmetrically can increase the stability of the slide rail when the vibration table vibrates.

[0018] By adopting the technical scheme, the crystallizer is connected through the spring hook and the sliding block in the slide, and the sliding block can only move in the vertical direction, so that the stability of the crystallizer in the horizontal direction is increased, and the vibration deviation of the crystallizer in the horizontal direction is reduced.
[0019] Optionally, a plurality of insertion holes are formed in the slide, the plurality of insertion holes are interval arranged along the length direction of the slide, a limiting block is arranged at both ends of the sliding block, the limiting block is slidably connected in the slide, and the limiting block is insertedly connected with the insertion hole.
[0020] By adopting the technical scheme, the position of the sliding block and the spring hook can be adjusted according to the position and height of the crystallizer, and when the sliding block is adjusted to the appropriate position, the limiting block is insertedly connected with the insertion hole, so that the sliding block is limited.
[0021] Optionally, a damping pad is fixed on the limiting block.
[0022] By adopting the technical scheme, the gap between the limiting block and the sliding block, and the damping pad of the limiting block itself, can achieve the damping effect on the sliding block.
[0023] In summary, the present application has at least one of the following beneficial technical effects:
[0024] The driving device at the bottom of the vibration table not only drives the vibration table to reciprocate in the vertical direction, but also limits the vibration range of the vibration table through the limit alarm in the slide rail, reduces the horizontal deviation displacement of the vibration table, and increases the vibration stability of the vibration table.
[0025] When the crystallizer is vibrated by the vibration table, vertical vibration of the crystallizer along the guide assembly also occurs. The connection of the spring hooks and the sliding blocks on the outer wall of the crystallizer can not only provide guidance for the vibration of the crystallizer, but also increase the stability of the crystallizer.
