In addition, the terms "first", "second" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] The utility model provides a device which can promote the solidification of molten steel in a crystallizer.

[0027] Reference Figure 3 and Figure 4 In this preferred embodiment, a device that can promote the solidification of molten steel in a crystallizer includes a cooling rod 3 for inserting into the copper tube of the crystallizer, wherein the cooling rod 3 is made of metal material (can be made of silver-copper material), and a cooling water circulation channel 32 for cooling water is provided inside the cooling rod 3.

[0028] Furthermore, the device for promoting solidification of molten steel in the crystallizer further comprises a clamping device for clamping the cooling rod 3, the clamping device comprising a support base and a clamping claw, the clamping claw can move up and down relative to the support base. The support base and the clamping claw are slidably connected by a linear guide rail, so as to stably drive the cooling rod 3 to move up and down, so as to be inserted into the crystallizer.

[0029] This embodiment proposes a specific structure of a clamping claw: a through hole is provided on the clamping claw for the cooling rod 3 to pass through, the top end of the cooling rod 3 is passed through the through hole, a fastener is passed through the clamping claw and its end abuts against the outer wall of the cooling rod 3 to fix the cooling rod 3. The axis of the fastener is arranged horizontally.

[0030] Specifically, in this embodiment, a partition 31 is provided inside the cooling rod 3 to separate the cooling water circulation channel 32 into a water inlet channel and a water outlet channel, and a water inlet and a water outlet are provided on the top of the cooling rod 3. The water inlet channel is connected to the water inlet, and the water outlet channel is connected to the water outlet. The partition 31 is integrally formed with the cooling rod 3.

[0031] In this embodiment, the cooling rod 3 is a hollow rectangular parallelepiped structure.

[0032] Furthermore, the device for promoting solidification of molten steel in the crystallizer further comprises a cooling water supply system connected to the cooling water circulation channel 32. A temperature detection device is installed on the outer wall of the cooling rod 3, so as to facilitate detection of the temperature of the cooling rod 3. A scale line is arranged on the outer wall of the cooling rod 3, so as to facilitate the operator to see and understand the current insertion depth of the cooling rod 3.

[0033] Furthermore, the clamping claw can move laterally relative to the support base, so as to facilitate adjusting the insertion position of the cooling rod 3 according to the position of the crystallizer. For example, a transverse support and a vertical support can be provided, the clamping claw is mounted on the transverse support and connected to the transverse support in a transverse sliding manner, and the transverse support can move up and down relative to the vertical support, so that the clamping claw can adjust the position laterally and vertically.

[0034] like Figure 1 and Figure 2 As shown, when the molten steel enters the inside of the crystallizer copper tube 1 through the water inlet and reaches a certain liquid level, the molten steel will cool and crystallize to form a shell of a certain thickness on the surface of the crystallizer copper tube 1 in contact with the molten steel. Without other means, the thickness of the shell is basically fixed and cannot be increased, and thus the production speed cannot be further increased.

[0035] like Figure 3 and Figure 4 As shown, after a cooling rod 3 with cooling inside is inserted into the molten steel of the crystallizer copper tube 1, the molten steel will be cooled and crystallized on the outer surface of the inserted cooling rod 3, which is equivalent to increasing the area where the molten steel is cooled and crystallized. When the molten steel cooling and crystallization area outside the cooling rod 3 is close to the molten steel cooling and crystallization area inside the crystallizer copper tube 1, the two cooling and crystallization areas will merge to form a billet shell with a larger thickness, thereby being able to increase the production speed.

[0036] The device proposed in this embodiment for promoting solidification of molten steel in a crystallizer has the following beneficial effects:

[0037] 1. This device can promote the solidification of molten steel inside the crystallizer, thereby increasing the production speed. It also has the advantages of simple structure, very simple and convenient use, and easy implementation;

[0038] 2. The installation position of the cooling rod 3 can be flexibly adjusted at any time according to needs;

[0039] 3. The cooling rod 3 can be taken out at any time without affecting the existing equipment.
