[0002] The crystallizer used in the continuous casting machine is a very important component of the continuous casting machine. It is called the "heart" of the continuous casting equipment. The crystallizer is a bottomless steel ingot mold with forced water cooling. It is mainly used to receive the molten steel injected from the intermediate tank and solidify it into a solid billet shell according to the specified cross-sectional shape. Its structure, material and performance parameters play a decisive role in the quality of the ingot and the production capacity of the casting machine. The Chinese invention patent, authorization announcement number "CN114932205A", discloses a crystallizer lubrication device for a continuous casting machine, including: a crystallizer body, a water injection pipe and a shaking sleeve. Graphite plates are movably installed on both sides of the inner wall of the crystallizer body, and a fixed plate extending from the crystallizer body is fixedly installed on the outer side of the graphite plate.

[0003] The above technical solution is provided with a water storage tank, a water seepage hole and a graphite plate that cooperate with each other. When in use, oil is injected into the interior of the crystallizer body. Through the contact between the steel and the graphite plate, since the surface of the graphite plate is relatively smooth, it can conveniently play a lubricating role during use. At the same time, water can seep into the interior of the crystallizer body through the water seepage hole, which can quickly cool the surface of the steel to form steel slag, and it is not easy to stick to the interior of the crystallizer body, making it more convenient during use and increasing the working efficiency of the steel. During the cooling process, a lot of residues are left at the bottom of the crystallizer. If the residues are allowed to accumulate at the bottom of the crystallizer, it is easy for debris to form a whole with the subsequent steel to be cooled, affecting the quality of the subsequent steel.

The surface of the sealing gasket 14 contacts the bottom of the crystallizer body 2.

[0032] A collecting hopper 4 is welded to the outside of the crystallizer body 2 and is arranged directly below the bottom plate 13 .

[0033] A motor gear 21 is installed on the surface of the crystallizer body 2, and the output shaft of the motor gear 21 is fixedly sleeved with a motor 20. A gear 28 is fixedly sleeved on the surface of the internal threaded sleeve 17, and the surface of the gear 28 is meshed with the surface of the motor 20.

[0038] When it is necessary to drain the oil mixture;

[0039] First, start the motor 12. The start of the motor 12 drives the gear 11 to rotate. The rotation of the gear 11 drives the motor gear 10 to rotate. The rotation of the motor gear 10 drives the motor 12 to rotate. The rotation of the motor 12 drives the internal threaded sleeve 23 to rotate. The rotation of the internal threaded sleeve 23 drives the threaded rod 22 to move. The movement of the threaded rod 22 drives the bottom plate 13 to move downward. The downward movement of the bottom plate 13 drives the bottom plate 2 15 to move downward.

The water-oil mixture flows into the interior of the collecting hopper 4 through the gap between the sealing gasket 14 and the bottom of the crystallizer body 2.

[0040] When it is necessary to clean the debris on the bottom plate 2 15;

[0041] First, start the motor 12 to drive the bottom plate 2 15 to move downward to a suitable position, then start the motor gear 21. The start of the motor gear 21 drives the motor 20 to rotate, the rotation of the motor 20 drives the gear 2 18 to rotate, the rotation of the gear 2 18 drives the internal threaded sleeve 17 to rotate, the rotation of the internal threaded sleeve 17 drives the threaded rod 19 to move, and the movement of the threaded rod 19 drives the cleaning brush 16 to move to clean the metal debris on the bottom plate 2 15.

[0042] By setting up a cleaning component and a sealing component, when it is necessary to clean the debris on the bottom plate 15 at the bottom of the crystallizer body 2, it is only necessary to start the motor 12 to drive the bottom plate 15 in the sealing component to move downward to a suitable position, and then the cleaning component drives the cleaning brush 16 to move to clean the debris on the bottom plate 15. This can prevent the debris that sinks to the bottom plate 15 from accumulating and affecting the quality of subsequent steel, that is, ensure that the bottom of the crystallizer body 2 is clean enough during each cooling, and prevent the debris on the bottom plate 15 of the crystallizer body 2 from affecting the quality of the steel, that is, ensure the surface quality of the steel after each cooling.

[0043] By setting up a sealing component, when it is necessary to quickly separate the water-oil mixture inside the crystallizer body 2 from the inside of the crystallizer body 2 and to add subsequent water and oil, it is only necessary to start the motor 12 to drive the bottom plate 2 15 to move downward, open the bottom of the crystallizer body 2, and quickly separate the water and oil inside the crystallizer body 2.

[0044] Since both water, oil and debris can be recycled, by setting up a collecting hopper 4, the collecting hopper 4 can cooperate with the cleaning device to collect metal debris, and the collecting hopper 4 can also cooperate with the sealing component to collect water and oil, thereby reducing the cost of cooling steel and the like.

[0045] Working principle:

[0046] When it is necessary to drain the oil mixture;

[0047] First, start the motor 12. The start of the motor 12 drives the gear 11 to rotate. The rotation of the gear 11 drives the motor gear 10 to rotate. The rotation of the motor gear 10 drives the motor 12 to rotate. The rotation of the motor 12 drives the internal threaded sleeve 23 to rotate. The rotation of the internal threaded sleeve 23 drives the threaded rod 22 to move. The movement of the threaded rod 22 drives the bottom plate 13 to move downward. The downward movement of the bottom plate 13 drives the bottom plate 2 15 to move downward. The downward movement of the bottom plate 2 15 drives the sealing gasket 14 to move downward and no longer seals the bottom of the crystallizer body 2. The water-oil mixture flows into the interior of the collecting hopper 4 through the gap between the sealing gasket 14 and the bottom of the crystallizer body 2.

[0048] When it is necessary to clean the debris on the bottom plate 2 15;

[0049] First, start the motor 12 to drive the bottom plate 2 15 to move downward to a suitable position, then start the motor gear 21. The start of the motor gear 21 drives the motor 20 to rotate, the rotation of the motor 20 drives the gear 2 18 to rotate, the rotation of the gear 2 18 drives the internal threaded sleeve 17 to rotate, the rotation of the internal threaded sleeve 17 drives the threaded rod 19 to move, and the movement of the threaded rod 19 drives the cleaning brush 16 to move to clean the metal debris on the bottom plate 2 15.
